What is Home Theater?

Home theater is more than a big screen TV. True home theater combines sight and sound to duplicate or surpass what you experience in the movie theater. Several factors come together to make a true home theater experience.

  • Screen – The size of the picture is important only in that it fill the proper “look angle” from the viewer’s seats. A 19″ tube is perfectly acceptable in a small apartment space; a 60″ screen will strain the viewer’s peripheral vision, just as sitting in the front row of a theater would not be pleasant after the first few days.
  • Seating – Your theater must be able to seat each viewer comfortably. And all must have an adequate perspective on that screen. A ratio of about 3:1 is about right – this translates to putting your eyes about 5 feet away from your 19″ TV. A 2: 1 ratio is OK for immersing yourself into a movie, but it’s a bit close for Tom Brokaw. And 5:1 is the outer limit – after that, you will find yourself leaning forward to see the details. As for seating off the center line, about half the distance to the screen is about it. So for seating spread, that’s 5 feet of couch space for your 19″ set.
  • Sound – The sound image should be centered around the screen. Additional are positioned to add depth.
  • Lighting – The management of ambient light can enhance your viewing experience – too much and it’s a wash out, too little and you’re stumbling around in the dark.
  • Control – One key to taking full advantage of each aspect of your Home Theater is to be able to control it simply. One small set of buttons should turn it on , change modes, channels & volume, and shut it down.
  • The Room- A basement is one of the best places to install a home theater. Controlling light is usually easier in a lower level because there’s less outdoor light interference. And the ability to insulate the ceiling and walls makes it possible to keep out a lot of distracting sounds and avoid disturbing other areas of the house. Another factor to consider is the size of the equipment. This is particularly an issue with the larger rear and front screen projectors. The basement often has extra space for equipment and avoids using valuable living space upstairs.

What are HDTV and DTV?

  • Analog TV Broadcast (also known as NTSC): A video signal in the form of a wave that constantly changes shape as color, brightness, and motion within the video image change. We will be referring to this as a traditional signal or picture.
  • Digital TV (DTV): A technology that transmits information as ones and zeros as opposed to transmitting the information in wave form. The digital signal is read by a digital TV much like a computer.
  • HDTV: Otherwise known as High Definition Television, HDTV ties together the clarity of digital TV and the superb quality of Dolby Digital Surround Sound for the ultimate entertainment package. HDTV offers 720 to 1080 lines of resolution, and as many as 2 million pixels; analog only brings 480 lines to the viewing screen, and no more than 211,000 pixels. In terms of hardware, an HDTV refers to units that include both the high-definition receiver and the viewing screen.
  • HDTV Monitors: These are TVs that can display digital TV signals once they are connected with separate high-definition receivers.{/slide}

What’s Meant by HD-Ready?

Some HDTV sets on the market incorporate HD-capable displays coupled with a built-in HDTV tuner to receive over-the-air HD broadcasts. However, the majority of HD-capable TVs on the market are what’s known as HD-ready TVs (or HDTV monitors) – high-definition displays, often including one or more built-in NTSC TV tuners for reception of conventional analog TV broadcasts, but which must be connected to a separate HD source in order to realize their full potential. Since most current HD content is delivered via satellite or cable systems rather that over-the-air, some consumers (especially those who reside in areas where over-the-air HD content is not yet available) consider an HD-ready set to be the best solution for their current and future needs. But to experience HD broadcasts (where available) right out of the box with no additional investment, a built-in HD tuner is the ticket.

What is Aspect Ratio?

Aspect ratio describes the ratio between the width and height of the screen. Conventional TV screen resolution is 4:3, meaning that the width is one and a third times greater than the height. Many systems are now coming out in a 16:9 resolution; this is the same resolution as wide-screen movies as well as HDTV. If you plan on watching wide-screen movies or upgrading to HDTV, you may want to consider a television with a 16:9 aspect ratio.

What is Resolution?

The number of pixels in a video image. The greater the number of pixels, the higher the resolution. The pictures we see on traditional analog TVs are supposed to be made up of 525 horizontal scan lines. But since some of those lines are used for things other than the picture, the truth is that the total is closer to 480 horizontal scan lines, which is why the standard is called 480i and not 525i. Regardless of the source-DVD, laser disc, antenna or satellite, or VCR-the picture most of us look at today is always made up of about 480 lines of information.

High-definition HDTVs and HDTV monitors (which require a separate set top box to receive HDTV broadcasts) are able to show images with 720 and 1080 horizontal scan lines.

What is Interlaced or Progressive?

This refers to the way in which the TV picture is put together. Currently, the 480 lines of information that create a picture on your TV screen are put together in an odd-even pattern called interlacing. First the odd lines of the picture are placed on screen (1, 3, 5, etc.) and then the even lines (2, 4, 6, etc.). This process is done continually and so quickly (30 complete frames every second!) that we perceive them as full motion.

The other way to “paint” a picture on a screen is a method called progressive scan, and it’s found only on HDTVs and HDTV monitors because only digital broadcasts and sources like DVD players send a signal this way. Like computer monitors, progressive scan creates a picture by scanning the lines in order, all lines at the same time (1, 2, 3, etc.). The way the picture is created is just one factor that determines picture quality. But that one factor is a big deal when it comes to DVD players. You see, more and more DVD players have progressive scan outputs that are designed to connect to an HDTV or HDTV monitor.

Which Size TV is Right for You?

Is bigger always better? Not necessarily. The size of the room your TV will be located in and the source you’ll be using to receive images are important (and often ignored) considerations when shopping for a new TV.

Best Video Source Formula
Off Air Antenna/Cable/VCR # of ft from TV x 4 in = Optimum Screen Size
Satellite TV/DVD # of ft from TV x 6 in = Optimum Screen Size
Digital or HDTV # of ft from TV x 7 in = Optimum Screen Size

 

What are the Differences in Sound Technology?

Improvements in home theater sound have brought the “feel” of cinema sound to the comforts of one’s own home.

  • Dolby® Surround Sound- This is the predecessor to Dolby® ProLogic and it only has right left and rear channels (3 total). The sound is less focused and dialog is less clear, but it still provides a nice overall surround effect.
  • Dolby® Pro Logic- Still one of the most common surround sound technologies, this system uses just three audio channels to create surround sound from 5 speakers (front right, center, left and two rear). The information you’ll need for Pro Logic surround sound is found on virtually every VHS movie you’ll find at your video store. To hear Dolby® Pro Logic, you’ll need a receiver with a Pro Logic decoder, 5 speakers, and a HiFi source like a VCR or DVD player.
  • Dolby® Pro Logic II- This surround system is designed to create a surround sound experience from virtually any stereo source. Using advanced matrix processing, Dolby Pro Logic II employs all five speakers (right, center, left, right surround, left surround) in a home theater system to turn your favorite CDs or old movies into multi-channel theater.
  • Dolby® Digital – This type of surround sound can have as many as 6 separate channels (front right, center left, right and left surround, plus subwoofer) of high quality digital surround. These discrete channels can create realistic sound effects that move around the room and bring movies to life. Dolby Digital soundtracks are found on digital sources like DVD and some high definition television broadcasts.
  • Dolby Digital® / AC-3® – This newest, most sophisticated type of Dolby surround sound features six discrete channels of digital sound (right and left front, right and left rear, center, and subwoofer) for the most convincing surround effects. Dolby Digital differs from Dolby Pro Logic with a better separation of channels and the addition of individual channels for both surround speakers. This allows for more precise sound fields and adds more depth and realism to the home theater experience.
  • Digital Theater System-DTS Decoding- Like Dolby® Digital, DTS is a 6-channel digital surround format that provides a separate channel of sound to five speakers (right, center, left, right surround, left surround) and a subwoofer. Probably the biggest difference between DTS and Dolby® Digital is the level of compression used. DTS insists that its lower levels of compression make a noticeable difference in the sound quality, and many people agree. On the other hand, many serious listeners and reviewers disagree. Fortunately, you don’t have to choose between the two formats because more and more of today’s surround sound receivers have the ability to decode both DTS and Dolby® Digital soundtracks.
  • THX® – THX is not a brand name for home theater equipment, but is a licensing technology to ensure the highest standards for the best reproduction of theater-type sound. Dolby and THX are not in competition with one another, and they often work together to create high quality theater and home theater experience. THX is the gold star standard for acoustics, and speaker placement, and certifies equipment that is capable of playing the best sound. Home THX changes the sound created for a large theater to sound more suited for the smaller and closer environment of home theater. To achieve this, a home THX system must include certified Home THX equipment.

What are the Basic Home Theater Components?

The very basic elements necessary to create a home theater are a large screen television, a movie playing device, speakers, and a surround sound capable controller or audio receiver. Understanding each component’s role is helpful when making choices on which ones to buy.

Televisions

  • CRT- The original TV was a box that used a tube (CRT) to display an image broadcast from a television station. Most sets used at home resemble this. Most of us have a TV with a screen that measures from 20-inches to 32-inches. As the screen got larger the box got heavier and deeper. This means that a CRT TV with a 36-inch screen would have a depth of about 26 inches and weigh about 200 pounds. Most of these are analog but some are DTV capable. They, for the most part, have traditional 4:3 images. Some models offer 16:9 with 30-inch or 34-inch screens. CRT screen sizes are limited because the size and weight of the set becomes prohibitive as screens extend toward 40-inches.
  • LCD consists of a layer of a liquid crystal solution that is sandwiched between two plates of polarized glass. When combined with a color filter, a Thin Film Transistor (TFT) and a backlight, it creates a super-thin television with an amazing picture. Extremely thin and lightweight, LCD offers small screens at 17-inches or less that are extremely affordable. In addition to notebook computers, you’ll find LCD screens in portable DVD players, pocket TVs, pocket PDA organizers, and handheld GPS direction units. LCD Flat-panel TVs go up to about 30-inches. At below 17 inches in size, these flat-panels are extremely affordable but, at over 18 inches, their prices increase dramatically. A 30-inch LCD screen may run about the same price as a typical 42-inch plasma screen. The LCD, however, is extremely reliable for long life and image constancy, especially when used with rapid video images and video games. Plasma offers superior contrast and color saturation but has a lower track record on longevity.
  • Plasma technology is a gas-like substance that, when squished between two panels of glass and excited by electricity, creates a crystal-clear picture. Originally developed in 1964, the technology involves charging gas particles in a multiplayer chamber. It is the highest priced screen. At about 4 inches thick, it is also the thinnest screen. Plasma offers very large screen sizes. It offers bright, vivid color performance at screen sizes from about 37-inches to over 70-inches. Of the flat-panel screens, Plasma delivers the best contrast along with the purest black colorations.
  • Rear Projection TV – The most common and affordable large screen TV system, Rear Projection integrates two or more small internal television devices in a cabinet, magnifies the images and reflects it with a mirror onto a translucent screen. This technology enabled televisions with screen sizes up to 70 inches that were less than 25 inches deep. The drawback was that the resulting image was a magnified reflection and suffered a loss of sharpness and brightness. Nonetheless, the large size screen, the more compact size (compared to CRT), and the affordability continue to attract many buyers and fans. There are essentially two types of rear projection TVs:
    • CRT Rear Projection – Instead of having a single CRT pointed right at you, three CRT tubes – a red, a green and a blue – are aimed together at a focusing lens which bounces the picture off of a mirror and onto a translucent, plastic screen, which presents the image that you’ll look at. Though these sets weigh a lot, they allow a larger screen in a box that’s more compact. What’s more, the three tubes sometimes need periodic alignment, or the red, green and blue will end up off kilter. Color and contrast is very good but brightness is lost. You need to view this TV in a dimly lit room. In addition, because you’re looking at a reflection the angle of view is somewhat restricted. This means that if you look at the image directly from the front, picture quality will be good. If you move up, down, left, or right, you may lose view of some or the entire image. These sets, though they may have widescreen viewing, are usually not considered for HDTV use and are the only rear-projection TVs that use a tube-based system.
  • LCD Rear Projection – TV combines rear-projection with LCD technology. This eliminates the need for convergence and special settings that CRT displays require. The result is a high-resolution picture with less risk of “burn-in” and greater versatility, like the ability to double as a computer monitor. This TV shines a light through three LCD panels, taking their red, green and blue moving images and reflecting them in a similar fashion. The key difference is that LCD panels are thinner and lighter than CRTs so the box is considerably lighter and thinner (16 to 20 inches deep). Rear-projection LCDs are known for high resolution and brightness, which means that they can meet the demands of HDTV. The brighter images allow more comfortable viewing in illuminated rooms and LCD reflections offer a wider angle of viewing than CRT rear projection. A downside of the bright image, however, is that ‘black’ colors and shades are less dark and tend to appear as very dark grays. Many hardly notice this.
  • LCOS Rear Projection – LCOS is ‘Liquid Crystal on Silicon’ and is a more advanced type of LCD screen technology. LCOS offers a very bright, sharp picture with virtually no degradation in contrast. Like LCD, LCOS allows a slimmer and lighter box.
  • DLP Rear Projection – DLP (Digital Light Processing) is supported by a single micro-display panel no larger than a postage stamp. Within this tiny bit of technology, more than 1 million mirrors allow pixels to refresh thousands of times per second. A color wheel then filters the light into more than 16 million possible colors and delivers digital images in astonishing clarity. A fully digital process, its advocates tout it as perfectly suited for the increased performance of DTV and, of course, HDTV. By minimizing the gaps between pixels in a projected image, DLP projection systems create a seamless digital picture that’s sharp at any size-without the pixellation or “screen door” effect apparent in other technologies”.
  • Front Projection TV – Front projection projects the TV image onto a screen. They are most commonly used with computers for presentations to large groups of people. Most of these have inputs that permit connection of DVD, VCR, and TV tuners so you can adapt them easily for home entertainment. Image performance can be very good and you can use very large screen sizes. Like a projected movie, however, you must view images in rooms that are dark for best performance. Like rear projection models, there are CRT-based, LCD, and DLP projectors available. Because of size and weight, CRT front projectors have become least popular. Most models are LCD and DLP, which are portable and lend themselves well to DTV and HDTV applications.

Receiver or Controller

In most home theater systems, the receiver is the brain of the system. It is where all the audio comes together and then. Most home theater receivers have inputs and outputs, a built in tuner, surround sound capabilities, built in amplifiers, and some even have a built in equalizer. High-end systems will most likely have a controller instead of a receiver. In this case, the controller is the most important piece in the system. It processes the audio tracks coming from the source, divides it into the various channels, and sends them to the separate amplifiers. The controller also handles both audio and video signals and acts as a switching device between the different sources.

  • Amplifier- Amplifiers are the power behind the system. Amps should be able to handle the huge range of frequencies found in movie soundtracks and they should be able to do it without distortion or clipping.
  • Tuner- A home theater system utilizing a controller instead of a receiver will need a separate tuner for radio stations. Most tuners today are digital with multiple preset buttons and scanning features.
  • Equalizer – Once a room’s acoustics have been physically optimized as much as possible, the addition of an equalizer will fine tune the room’s acoustics and balance the frequencies.

CD Player

Home CD players today come in three basic varieties: single play, changers or “mega” changers. The most popular players are the 5 or 6 disc changers but as disc collections have grown, mega changers with 100-300 disc storage and play capabilities have also become more popular.

DVD Player

Stands for Digital Video Disc or Digital Versatile Disc, depending on who you ask. DVDs look just like CDs, but contain high quality video and multi-channel audio. Some home theater systems come with DVD players and some don’t, but using digital sources like DVD are the only way to take advantage of digital surround sound modes like Dolby® Digital and DTS.

VCR

Still a common playback source is the VCR. Its biggest advantage is recordability. Disadvantages of the VCR include tape wear and damage, non-instant access, and on a large-screen TV, the resolution just doesn’t compare with the resolution achieved with DVD players.

Digital Video Recorder

A digital video recorder (DVR) is like a VCR on steroids, allowing you to record as many as 140 hours of programming onto a built-in hard drive, eliminating the need for tapes. Digital video recorders let you record shows, pause live TV and fast forward to the best parts, without needing tapes or discs. Watch the shows you want, when you want.

DSS Reciever

A satellite dish (about the size of a large pizza) receives a signal and connects to a Digital Satellite Systems (DSS) receiver. They receive digital satellite signals that carry superior image capabilities similar to a DVD with CD quality sound. They’re easy to setup and tune in and will be able to accept future television standards like high definition television and six-channel surround sound. Monthly service plans cost about the same as standard cable service.

HDTV Receivers

Not all HDTVs come with built-in high definition receivers. These are HDTV monitors. While they’re capable of displaying high-resolution 720p (720 lines of information in progressive scan format) and 1080i (1080 lines of information in interlace format) pictures, these TVs can’t do the job alone. Rather, HDTV monitors must be connected to a separate HDTV receiver. It’s this receiver that gathers and translates digital information into a form understood by the HDTV monitor so it can then display the picture.

Line Doubler

The quality of a projected video image on a large screen can be improved in quality by using a line doubler. A video image is made up of approximately 500 horizontal scan lines, but because of the way it scans, only half the lines are shown at one time. A line doubler presents all the scan lines at the same time, thereby increasing its sharpness. At the same time it cleans up imperfections in the video signal. A line quadrupler does the same and adds information between the scan lines for even higher resolution.

Interpolator

An alternative to a line doubler or quadrupler is an interpolator. It also increases the quality of a projected video image on a large screen but in a different way. An interpolator determines the optimal scan rate for the monitor used. It then creates and fills in the picture information to precisely fit that monitor for the best quality image. An interpolator also changes aspect ratios on the monitor to match the format of the source signal. An example would be a letterbox image can be made to fill a screen eliminating the top and bottom banding. An interpolator mixes video and computer images which electronically are very different, and until now could not be mixed. This capability may become more essential in the future as video and computer applications converge.

Speakers

Since sound attributes to half of the home theater experience, it’s a good idea to get the best speakers you can afford. Like amplifiers, speakers should be able to reproduce a large frequency range clearly without distortion. No two speakers sound alike so selecting them is often a matter of personal listening preference. Any speaker placed within 2′ of the television needs to be magnetically shielded to avoid signal breakups and picture distortion. Most speakers marketed toward home theater are shielded, but it is an important item to verify.

A home theater needs at least six speakers: left front, right front, center front, two surrounds, and a subwoofer or bass module. For a DTS or Dolby Digital system, all six of these speakers should be capable of a full range of sound and be fairly equal in quality. For anything up to and including Pro Logic technology, there is some differentiation.

  • The left front and right front speakers carry the bulk of the music and sound effects in a home theater. These speakers should be high quality and able to handle a wide range of sounds.
  • The center speaker is the primary carrier of dialogue and should therefore be the same quality as the left and right front speakers. Ideally, it should be the exact same speaker, or at least matched in quality and power.
  • For most home theater systems, the surround speakers can be smaller in size because they do not need to carry the booming bass. They should put out at least half the power and match the front speakers as close as possible in sound quality and balance for an even sound.
  • Subwoofers reproduce the low bass sounds that make movie effects like explosions, sonic booms, crashes, and dinosaur footsteps seem realistic. These are the sounds that really pull you into the experience and a good subwoofer or bass module is needed for a full effect.

Rack System

You can see by the list of equipment that a home theater system can take up a lot of room. A rack system organizes the components and helps to keep pieces orderly and neat looking. Some rack systems come with rollers which slide completely out of the cabinetry making it easier to get at the cables on the back to make changes. Modular rack systems also make it easy to add components in the future.

Cables & Interconnects

They may seem relatively unimportant compared to the rest of the equipment, but cables and interconnects can make a difference between a good sounding system and a great sounding system. This is true on any size system from the low end to the highest quality. The signals between components and speakers need to flow unrestricted or the output will suffer.

Cables should be a heavy gauge and the connectors should be gold plated. Some experts even say to allow as much as 10% of your home theater budget for cable.

Remote Control

Most electronic equipment has a remote control. Imagine a whole rack full of components each with individual remotes — you know that the coffee table probably won’t be big enough to handle them all! But you still need to be able to control all those devices. If you happen to purchase all your equipment from the same manufacturer, you might be able to control everything from the receiver remote. But most people don’t buy everything from one manufacturer and that’s where a universal remote comes in.

There are a number of sophisticated systems out there that will not only do the job but make things a little simpler. A high-end touchpad system we installed includes a tabletop device with a large screen programmed to control each component. There’s a screen for each component with icons that represent different functions. Simply press the symbol on the screen and it performs that function.

The remote transmits information by radio waves rather than the traditional infrared waves so you can keep the components behind closed doors and still be able to operate them. Inside the rack is the remote receiver that takes the information from the radio waves, processes it and sends a command via infrared through wires to the component.

Connecting Components

Sketching out a simple connection plan can be helpful for installing a home theater system. This can help to figure out the general layout of the elements, considering cable connector lengths, the best location for remote usage, easy setup and maintenance.

Exactly how home theater components are physically connected varies according to what equipment is being used. The owner’s manuals will be a great help in this department. If you have a lot of equipment, you might consider hiring a professional to install the system

What are Some Potential Placement Problems?

Many times there are features to a room that dictate where a home theater can go.

  • Built-in shelving, wall length, size and shape of the room, windows, etc., can eliminate an entire wall or half the room as placement possibilities.
  • The equipment itself often dictates its location. The larger the screen, the farther the distance must be between it and the sitting area. As the layouts below illustrate, larger screens require more distance from the viewing area.
  • There is an optimum height range for a seated person to view the screen to avoid strain or uncomfortable viewing positions. This height may or may not fall in line with other elements in the room like a shelf or soffit line.
  • A system installed in a large, open space with no adjoining spaces to put components will likely need a custom-built cabinet to house it.
  • Wood cabinetry constructed of plywood with a wood veneer is a good choice. It is easier to match woodwork without breaking the budget. Plywood and veneer cabinets are also structurally stable and don’t warp as easily as solid hardwood.

What is the Ideal Speaker Layout?

  • The front three speakers should be set around the television at nearly equal heights to each other.
  • The center speaker can be placed slightly behind the left and right speakers if necessary, but never ahead of them.
  • The left and right front speakers should be as close to a 45° angle as possible to mimic the conditions set by the mixer at the film studio.
  • Many people think that the surround speakers go directly behind the viewing area. Actually the best place for them is 2′-3′ above the viewing area and directly to either side of it.
  • For best results, the three front speakers should conform as close to the ideal layout as possible. Surround speaker placement has a little more leeway. In-wall and ceiling-mounted speakers are popular aesthetic and space-saving alternatives for surround speakers.
  • Sometimes sidewall, in-wall, and ceiling-mount speakers aren’t possibilities. In that case, alternate placement is necessary.
  • Speaker stands are another good alternative when a wall mount is not possible. Stands can be aimed at each other just as if they were mounted on side walls. Many speaker companies make speaker stands specifically designed for their surround speakers.
  • If possible, choose a room that has walls of different lengths to fight acoustical problems before they begin. Rooms with carpeting and padded furniture are better choices than room with hardwood floors or paneling, or lots of bare walls. One of the easiest and most helpful things to minimize acoustical problems is deaden the room. This can be done by hanging curtains or other sound-absorbing items on walls, and furnishing the room with big, soft furniture.
  • Moving speakers around to change the way they reflect off surfaces can help. Keeping subwoofers out of corners is a must because corners are notorious for creating standing waves.

What Other Factors Should be Considered?

When creating a home theater, there are some important details that can be forgotten — and it’s no fun to realize just a little too late that something was missed or overlooked. Remembering these details can help avoid wasting time and money.

  • Power and Plugs – Home theater is unforgivably dependent on electricity. With every piece of equipment added, more electricity is needed to power it. Therefore, the first thing to check before installing a home theater system is whether or not the house can handle the added electrical load. When dealing with expensive electronics, always protect your investment with surge protectors. Power surges can cause immediate and/or eventual damage to electrical equipment. Some cabinetry designed for home theaters have built-in surge protectors and multiple plug centers.
  • Ventilation – If the electronic equipment is enclosed in cabinetry, it can generate a lot of heat. The components that seem to generate the most heat are projectors, line doublers, DSS receivers, and amplifiers. The easiest way to keep the interior of home theater cabinetry cool is to install thermostatically controlled to switch on automatically whenever the interior temperature reaches a certain level. Most media fans are not very large, only about 4″ in diameter and 1½” thick, but are highly recommended by audio visual experts. Fans mounted in the top or bottom of cabinets work well along with additional ventilation space. Many home theater racks and shelves are made with extra room for ventilation in the rear, or other types of vents.
  • Dust Control – Dust can shorten the life of electronic components. Frequent dusting helps, but housing the system inside cabinetry is the best method of basic dust control. But enclosing a system doesn’t completely solve the problem because some dust is still introduced into the cabinet space by vent fans. Periodically wiping off the mirrors and other equipment helps, but can be difficult depending on the set up. Installing a media filter at the fan intake is a good way to lessen the problem. A media filter works like an elaborate forced air furnace filter. These work well because the filters can be changed when they get dirty.
  • Plan for Future Expansion – If there is even a possibility of adding onto the system in the future, choose equipment that has enough power, and inputs/outputs to handle additional components.
