TV and Sound System Installation

Monday, September 19th, 2011

The easiest way to get the right TV and music system installation is to speak with a qualified system designer well before you buy anything.  Most people don’t realize the planning that should go into setting up a TV or music system.  Even a system as simple as a TV on the wall with a cable box can be installed cheaper, and perform better, with the proper planning.  Without proper planning, coaxial cables, data cables, speaker cables, and line-level cables are often run to the wrong place or left out entirely.  A home cannot be pre-wired correctly, and at minimum cost, without the homeowner’s anticipated needs being taken into account.  If construction is already going on in the home, it’s advantageous to have that conversation with an a/v designer at least one month before the work is finished.  This way, your audio/video outfit can wire while your place is torn apart, rather than have to make fresh holes which you’ll have to fix!

Lots of homeowners don’t like to have this conversation with an audio/video specialist.  They may think that the gear they buy will automatically do what they need, because their needs are simple.  They say they wouldn’t know what to talk about with a system designer.  They say, in their own way, that they’re not audiophiles or videophiles.  But, there is no correlation between the need for planning and one’s passion for, or knowledge of, things audio or video.  Rather, planning is required to correctly execute certain types of installations and to fulfill certain user needs.

Again, it’s not about how much the end-user loves music or movies.  Indeed, a real hi-fi freak may need no planning, because his interest is in state of the art equipment sitting in an open rack—the better to regularly move gear around.  An example is the enthusiast who constantly tinkers and “upgrades.”  There is no wiring behind walls for this guy, there is no wall mounted TV, and there is no equipment hidden in a closet or cabinet—three criteria that pretty much guarantee you need advanced expert planning.  On the other hand, the couple who want things looking neat and tidy, who might have some background music playing when company is over, who want to be able to plop down on the couch and watch TV at night without needing an engineering degree:  these are the ones for whom planning is critical.

Thinking that your needs are simple, and so not planning properly, will hurt you every time.  People who say their needs are simple often want the following system features. These features all require particular wiring, and additional equipment that is easily missed.

Features that necessitate an a/v plan before you wire:

  1. Ability to listen to TV through the TV speakers only, but also the ability to listen through the stereo or surround sound system.  For instance, some homeowners want the nightly news played through the TV speakers, and they want the HBO movie, or the 60’s music channel, played through the surround sound speakers.
  2. Ability to have music from one centralized audio system play in more than one room (i.e. a multi-room music system).  People will have their electrician or their builder handle this wiring without the audio/video system figured out in advance.  The resulting wiring is usually wrong.  Even a home theater expert would need a proper system design if he’s going to get the wiring right, and this design requires planning between the a/v designer and the client.
  3. Ability, in a multi-room music system, to play one thing outside—say the iPod—while cable TV is being watched in the Family Room.
  4. Ability, in a multi-room music system, to control volume from whatever room you’re listening in.
  5. Ability to hide the equipment from sight.
  6. Ability to see the TV from different angles.
  7. Ability, in a multi-room music system, to change radio stations, or songs on an iPod, or tracks on a CD (i.e. control beyond simply changing volume), from rooms other than the one the music system is in.

Lots of homeowners don’t like to have the planning conversation with a system designer because they want to buy at cheaper prices than the designer sells at.  This is missing the point, which is to not be penny wise and pound foolish.  Besides, it’s the good system designer who often saves people money by keeping them from more expensive equipment that they will not appreciate.  Indeed, as the TV market now stands, and has stood since the advent of flat panel TV’s, the TV that would make any given consumer most happy—even if any TV could be had for free—is almost never the most expensive one.   This is often the case for sound systems, as well.

Do yourself a favor, and reach out to your local audio and video specialist.  In addition to getting more for your dollar, or even spending less, the experience is usually more positive than when dealing with the big box retailers.  Consultations are often in-home, providing you with the undivided attention of the system designer.  Typically, when you need something else after the sale (e.g. more equipment, upgrade, service), you have the pleasure of dealing with an organization that remembers you.

Flat Panel Plasma, LCD, LED, 240mhz, Help!

Wednesday, March 30th, 2011
Purchasing a new flat panel TV is unnecessarily confusing for many.  Almost as much as price and size matter, knowing the viewer’s preferred picture matters as well.  Of course, that viewer may be you.

After satisfying their size, budget, and longevity concerns, many buyers will say that they want the best picture.  It’s this last point where the confusion can be avoided.  How?  They should figure out if “best” is for them.   For our purposes here, “best” will be defined as the TV having the most accurate image as determined by standard display testing using test equipment.  There are some relatively easy ways to decide if “best” is for you.  First, consider that the best picture has little to do with how vibrant the image looks in a room with electric or natural light. At roughly 4 times the resolution of even your best flat panel TV, the finest picture resolution by far is what you’re seeing at your better movie theaters (i.e. Some movie theaters show beat-up prints or digital movies, so we can’t count those.)  Well, that’s a pretty bad picture the theaters have got going—until the lights go down.  With the lights up, it’s washed out.

Like in the movie theater, if you go for the absolute best picture in your home then you need to watch with the lights very low.  This is because if your TV is adjusted to show maximum resolution, it won’t look too good with the lights up.  Right off the bat, our group of people who truly want the best picture has gotten a lot smaller.  If you’re someone so ruled out, then worrying over the absolute best picture performance might be a waste.

Of course, the best approach to buying a TV is to buy  from an experienced audio/video systems designer.   But, if you also like to learn on your own, a relatively fast (i.e. about 1 hour) and easy way to learn how to discriminate among displays, and to learn if “best” really interests you, is to watch the video portion of a particular test DVD.   I have personal experience using Joe Kane’s Video Essentials, so I can recommend that one.  For purposes of learning what makes a good picture, it doesn’t matter which version of Video Essentials, but if you think you will use the disc to maximize the picture on your new TV, then get the Blu-ray version.

If you’re so inclined, you could supplement the above knowledge by reading flat panel display reviews in Widescreen Review, Sound and Vision and Home Theater Magazine.  I’ve found that all of these offer good information.  (I’ve seen misleading information in the New York Times and Consumer Reports—so beware.)  After reading two issues worth of reviews from each of these you’ll come away a bit smarter.  But, you really won’t know what they’re talking about without doing the test DVD exercise I mentioned.  And, unless something dramatic changes, I’ll bet you a steak dinner that if you read these reviews start to finish you’ll realize that the best displays are mostly plasmas.  (This is a heated issue for people who aren’t videophiles—but videophiles, and testers–know it to be true.)

If you want to spend still more time, and poorly, deciding which display to buy then:

  1. read the manufacturer’s performance specifications.  (For maximal waste of time, look at the contrast ratio.)
  2. compare displays by viewing them at a large retail chain.
  3. skim TV equipment reviews and don’t read between the lines for the acknowledgment that the piece under review isn’t the best.

I’ve found that most people would be much happier had they spent less on their TV and put the extra money towards an automated remote.  One button press and you’re watching TV, one button press and you’re watching DVD, one button press and you’re listening to music.  A system that is so easy to use is the stuff of make-believe in most people’s minds.  But, give them such a remote, and they’ll never go back.  Give them the “best” picture, and they may resent the fact that it’s achievable only in low light.

Careful With That Cable, Eugene.

Wednesday, June 30th, 2010

HDMI cables promise so much.  Instead of 3 component video cables and audio cables running to your a/v receiver or to your high definition TV, one HDMI cable will do.  Instead of a 1080i image resolution limit, as with component video, HDMI was designed for 1080P and higher.  Instead of 6 audio channels at lower-than-CD resolution, HDMI gives them at greater-than-CD resolution.  Instead of having to run a separate ethernet cable, future HDMI enabled devices will be networked via the same HDMI cable that carries audio and video.  And, the copy protection that Hollywood enjoys courtesy of the HDMI interface, the entire reason HDMI came about in the first place, is no doubt why the studios are willing to give us movies in high-definition.  They weren’t going to let high definition DVD (e.g. Blu-ray) happen via the component video outputs. Component video didn’t provide a satisfactory copy protection solution.

Yet, anyone who makes his living designing or installing audio/video systems knows that HDMI can add days of unpaid installation time, can cause massive frustration, and can leave customers wondering about who they hired and the wisdom of their a/v investment.  In a massively frustrating and seemingly unknowable way, HDMI often doesn’t work!

Consider what goes wrong with HDMI cables; problems which, by the way, our old component video and audio cables don’t have.  Cable boxes don’t display on TVs when HDMI is used to directly link the two.  Video doesn’t show up on TV screens when HDMI is run through a switcher (e.g. an A/V receiver) on its way to the TV.  Or, consider this teaser, which cost me personally about 8 hours of troubleshooting.  A cable box runs HDMI to a receiver, as does a Blu-ray player. Then, from the receiver, HDMI is run to the TV.   If the customer wants to watch the cable box, the only way is to first bring up the picture from the DVD player!  The knowledgeable folks at Denon recently informed me that this is a known problem.

It’s a rare installer of HDMI who hasn’t had these problems.  Of course, he checks the source component, checks the switcher, checks the display device, and he checks the cable and they all check out fine when used with other associated equipment!  It’s certain combinations of equipment—for the most part unknowable until you try them—that don’t work!  As I was recently informed while attending the above referenced Denon training, a lot of this has to do with poorly manufactured HDMI cables.  They’re not made to the standards that they need to be and, as of now, there is almost no way for the buyer to know.  (Kudos to DPL Labs (www.dpllabs.com) for establishing HDMI ratings for HDMI enabled equipment and for HDMI cables.  Consumers need more manufacturers to sign on to this program.)

Aside from needing quality cables, consumers often need firmware updates to get HDMI to work.  I’ve seen such an update work for a Time Warner cable box.  That customer was lucky Time Warner had an update available.  Just this week I saw a homeowner pay out an additional $580 for a component video and analog audio solution because the necessary firmware update, to get HDMI to work between his Fios box and his TV, isn’t yet available.  The customer is out $580 while the installer spent 8 hours of unpaid labor trying an HDMI amplifier, failed firmware updates, the suggestions of three tech support departments, and various other solutions since repressed by his tormented mind.

But wait—it gets better.  Indications are that component video outputs—which reliably give high-definition (i.e. 1080i) resolution—are being phased out.  This means you may not see them anymore on DVD players or cable boxes or satellite boxes or on A/V receivers.  Furthermore, even if they are present on future products, they will not output HD signals!  And, if you do install HDMI cable and if it does work now, it’s likely still not the kind of HDMI cable that you need to pass full resolution 3D video—OK, you may not care—or that you need to carry the Internet.  I know of only one vendor of such cable.  For those of you pre-wiring your walls, one solution to all this mess is to make sure your a/v designer specs high quality data cable to handle your high resolution audio and video needs, as well as your networking needs.

Is 3D Video What Surround Sound Has Been Waiting For?

Friday, June 11th, 2010

Seeing Avatar in 3D in Imax—film not digital, I didn’t want to chance it—was a singular event in my visual entertainment experience.  Seated about 25 feet from a 72.6ft x 52.8ft screen, the experience was akin to being in the scenes myself.  More accurately, it was good enough for the willing suspension of disbelief.  No other 3D I’ve seen is close to being that good.  The technology got out of the way so that the illusion was maintained.  No projectiles were flying at me, for one thing.  This was not gimmicky 3D.  And no aspect of what I was seeing, 3D wise, didn’t seem true.  Minor distortion on fast moving objects was the only visual cue that fell short—and I was looking hard for something to fault.  I did feel dizzy for about 2 minutes when I first donned the 3D glasses, and the image went dark for about a second when I first put the glasses on.

So unobtrusive seemed the 3D that I thought I could easily slip into the same presentation for any drama or documentary.  That is, this wasn’t 3D solely for movement and action– this was better than that.  This was simply a better way to get into a story, because I felt like I was at the story.  I want more of it.

About 3 weeks ago I saw a Mitsubishi DLP display a 3D video game.  It was a good 3D effect, but nothing like the theatrical experience that I had.  The screen needs to be a lot bigger, is what I thought—it was about 65”.  Some days later I saw a 3D demo disc playing on a 65” Panasonic plasma.  Impressive though it was when compared to 2D TV, it was artificial in pretty much the same way as a stereoscope (e.g. the View-Master toy).   I’m not saying I wouldn’t want to watch programming that way, but it was way behind Avatar in Imax 3D.

How far out into the future are we talking about, to get the Avatar experience in the home?  I’ve not seen any other theatrically projected 3D, but by all accounts Avatar is uniquely good.  I think I’d feel better for the prospects of the Avatar experience in our homes if Avatar wasn’t so alone in its quality.  Home projector manufacturers are also disturbingly short on information about when they’ll be selling 3D machines.

Are there some steps in the right direction?  Sure.  Widescreen Review magazine reports that Hollywood already released 16 major 3D titles in 2009.   A search of 3D movies at Blu-ray.com turns up about 19 3D titles, representing a mix of discs available now or available for pre-order or scheduled for release sometime this year.  DirecTV just updated their customers’ receivers—automatically—to receive HD.  DirecTV says they will be showing 25 World Cup games in 3D.  They say that this month will see the launch of 4 3D channels.  Comcast says they’ll be showing up to 25 World Cup games in 3D via ESPN3D—presumably the same games and network as DirecTV is offering.  And, 3D flat panel TVs and Blu-ray players are for sale now, and at prices lower than when flat panel and Blu-ray debuted.

Wouldn’t that be something if video reproduction got as realistic as audio reproduction?  Am I the only one who thinks the juxtaposition of surround sound with a 2D screen is so incongruous that it’s distracting?

I know—them’s fightin’ words!

“You’ll put those speakers in here over my dead body!”

Monday, September 14th, 2009

For about 90% of the custom installations I’ve seen, hiding the gear is the name of the game. When you think about it, one of the reasons flat TVs are so popular is because they’re “hiding” that deep TV tube we all used to put up with.  Similarly, most people would like the cable box, DVD player, A/V receiver, and whatever else, hidden.  Oh sure, there’s the exception.  There are the folks who want to enjoy the pretty lights on their A/V receiver, or those who want to savor the fine finish on their speakers.  But, in the custom installation marketplace, these people are rare.  So, for those of you in the vast majority, following are some solutions for making all that gear disappear from view.

 

stereo
This traditional set-up, with speakers out in the open and a deep TV, is not for everyone.

 

Hiding Components (e.g. DVD players, CD players, radio tuners, amplifiers, A/V receivers, cable boxes, etc.)

A common solution is to hide the components in a cabinet with doors.

 

cabinetwithdoors

 

Some users will avoid this because they’re worried that their remotes will no longer work.  But, remote operation is maintained with remote repeater systems, starting at around $300.

Closets or basements may also be used to hide gear.  Just remember, if you have to load it (e.g. DVD player) or read it (e.g. Sirius tuner) then provide a convenient location.  This might mean a putting a DVD player close to the TV but hiding a receiver in a nearby closet.

 

Siriushometuner
Many tuners will display station numbers and song information, and so should be placed where they can be seen.

 

Hiding Speakers

Between the listener and the loudspeakers there should be nothing.  Within the confines of that one rule, you have a huge number of placement options.  For those who want absolutely no visibility, speakers that are designed to live behind paint or wallpaper are the solution.  (www.stealthacoustics.com) More often, homeowners are happy enough with flush mounted speakers in their walls or ceilings.  These come with white grills that may be painted or stained.

Some grills are even frameless, for an extremely clean look.  (www.sonance.com)

System designers will often use ceiling speakers that are the same size as the ceiling can lights, for a symmetrical, orderly look to the ceiling.  Still other speakers look like works of art, so they may be “hidden” in plain sight.

Other speakers look like planters.

And still other speakers are recessed into furniture, shelves, or walls, and covered with acoustically transparent fabric.

Subwoofers are made that go in floors, walls, and ceilings.  However, the best performing subwoofers sit out on the floor.  This can make some people unhappy.  Once again, a good carpenter can come to the rescue.

TVs, Projectors, Screens

Cabinets with doors or with built-in lifts have long been popular for concealing TVs.

TV’s may also be hidden on pop-up lifts that live under your bed.

Mirrors or paintings may also be used to hide TVs.

Projector screens might be hidden behind walls or above the ceiling (see below).

 

Screens may be recessed into ceilings.

Often, screen casings will be mounted to the wall or ceiling but be concealed behind some decorative fabric suspended from the ceiling.

REMOTE CONTROLS

As long as they remain hand-operated, remote controls must be out in the open because they need to be touched.   There is no real hiding this part of your system.  But, the programmable remote controls enable one to hide many other things.  For instance, instead of several remotes sitting on the coffee table, there can be one programmable remote. You can hide the other remotes in a drawer.

Instead of a bank of light switches and a security system keypad and an audio system keypad, there can be one in-wall touch screen controller that acts as all of those things.

Then, those devices that would have been making your walls ugly may get hidden in a closet wall.

As you can imagine, a lot of planning is required to implement the above solutions effectively.  Contact your local audio/visual specialist (www.dhaudioandhometheater.com) for help.  ■
