Why a Computer UPS Can’t Protect Theaters
CIS-NC's Choice For APC and Panamax Line Conditioners
Make sure to select a battery backup specifically designed for AV applications.
Power surges and transients occur in all 50 U.S. states. Blackouts, poorly filtered power, and dirty power can interrupt viewing, erase recordings and lose all of the system’s pre-sets. The recordings stored on your media server or DVR can be lost permanently if power is lost at just the wrong moment.
Satellite receivers and cable boxes can lockup, thereby interrupting service. Expensive light bulbs used in projectors and DLP TVs can be damaged when a blackout occurs.
The right battery backup can protect all of those troubles from happening. Many consumers look to their local mass retailer for one of those small, inexpensive battery backups designed for their home computer. While this might work out OK, there’s a good chance it simply won’t work.
Make sure to select a battery backup specifically designed for AV applications. Here are three reasons AV UPS (uninterruptible power supplies) systems offer better home theater protection.
Handling large components
One major difference is the ability to handle the unique power requirements of larger components. Network file servers and desktop computers typically have an in-rush current draw (the quick, but dramatic amount of current drawn when the device is turned on) of 60-80 Amps for a few milliseconds. Larger components can draw into the 100s of Amps (peak to peak) for several milliseconds on startup.
Computer UPS units are simply not designed to handle this large power draw. This can easily overwhelm the inverter of the UPS, causing it to shut down suddenly and unexpectedly. It is even quite possible for the UPS to be damaged by this overload condition. AV UPSs are designed to handle these large current draws common with big screen TVs and larger amplifiers.
Isolated Noise Filtration
Dedicated isolated noise filtration is another key aspect of AV equipment that is not typically available in computer UPS systems. Electrical Magnetic Interference (EMI) and Radio Frequency Interference (RFI) generally have little impact on computer gear unless its presence is extremely large (and/or the equipment is poorly shielded). For this reason, traditional computer battery backup products contain very small EMI/RFI filters.
If severe enough, EMI/RFI can negatively impact sound and video quality. Properly designed filters, as found in higher-end AV power protection units, can reduce or eliminate this interference so that consumer’s receive the best home theater experience their system can provide.
Too Noisy
Traditional computer UPS systems are too noisy, electrically and audibly, for AV equipment. Light emitting diodes (LED) and visual alarms that are typical of computer UPS systems can also detract from the viewing and listening experience. On the other hand, AV specific models are usually designed to be as quiet and visually unobtrusive as possible.
Audible alarms are “OFF” by default and LEDs can be dimmed or turned “OFF” altogether; similarly, liquid crystal displays (LCD) can be dimmed or turned “OFF”. AV cooling fans are micro-processor controlled with variable speed designed to run only when absolutely necessary.
Furthermore, the industrial design is ideal for placement in home entertainment centers (shelf or rackmount) or AV racks. Also, the UPS batteries are accessible through the front panel so the unit does not need to be removed from the equipment stack.
A true AV-specific battery backup can be a great complement to your system. Knowing you are protected from all the dangers and hassles of today’s unpredictable power grid should give you peace of mind so you can enjoy your home theater experience without interruption.

Sub-$6K Theater Delivers Satisfaction
CIS - Charlotte's Source For Home Theater Installation/Design
This budget-friendly home theater, and its 106-inch screen, provided the finishing touch to a finished basement.
One of the first things Phillip Thomas did after buying his 3,300-square-foot single-family home was finish the basement. He put in a bar, built a bedroom for his college-age son and threw in a nice-size bathroom. But he always felt that something was missing: a home theater.
“At the time, I thought that adding one would blow our budget out of the water,” Thomas says. So he and his family waited. After a few months of saving up, they contacted a local custom electronics professional for a quote. “They had a very firm budget of $10,000,” recalls Jason White of Commtech in Germantown, Md. “It was small, but it gave me some very clear parameters to work with.”
Since the basement was already finished and furnished, all of the money could go toward audio/video equipment and installation. That didn’t mean, however, that White could go crazy with the cash. “I had to be very careful about the products I selected,” he says. Obviously, the price of each component would need to fit the budget. But it was also important that the products chosen could be installed easily and would require minimal programming, White says. Oh, and the equipment would need to perform to the family’s expectations.
One of those expectations was a huge display. “I would settle for nothing less than 100 inches,” says Thomas. Consequently, the largest portion of the budget, $1,000, was allocated to a 106-inch projection screen from Draper. To avoid going over budget, fancy accessories like a motor that allows the screen to roll down from the ceiling were excluded.
A 720p Optoma projector finished off the projection system. Although it lacks the Full HD resolution of a 1080p model, it saved the Thomases more than $2,000. White made sure to run HDMI (high-definition multimedia interface) and extra Category 5 cabling to the projector location “just in case the Thomases ever decide to upgrade,” he says. The entire video setup came in at $2,000, which was about the same price as a much smaller 65-inch plasma or LCD TV.
White also stuck with the basics when it came to the audio/video receiver. The Denon AVR-590 is a quality piece, he says, but with one missing feature: HDMI upconverting. White explains, “A receiver with HDMI upconverting requires just one HDMI cable between the receiver and the projector. With it, any signal from any component will be upconverted to the 720p resolution of the projector.” The “HDMI switching feature” of the AVR-590, on the other hand, required White to route several additional cables from each component to the projector. The switching feature simply allows the signal from the connected source components to pass through to the projector without any enhancement in resolution. It was a minor sacrifice, White says, to save nearly $1,000.
Two fewer speakers would need to be purchased by going with a 5.1 surround-sound setup instead of a 7.1 system, and in-ceiling models would minimize the cost to have them installed.
“It’s usually easier to fish wiring through the ceiling to in-ceiling speakers than go through the ceiling and down the wall to install in-wall speakers because there are fewer obstacles,” says White. “It takes no more than five minutes to install an in-ceiling speaker compared to anywhere between 20 minutes to two hours for an in-wall model.” The 75-watts-per-channel rating of the five Proficient units may be less than the 100-watts per channel of the company’s higher-end units, but the Thomases saved $1,500 by sticking with the mid-grade models.
A final contributor to the savings was a stripped-down control device. The only two source components in the theater are a DirecTV satellite receiver and an upscaling DVD player, so the family didn’t need anything fancy, and so programming the URC MX-900 remote was basic.

4 Tips for Cleaning Screens
C.I.S. - Charlotte, NC's Home for Samsung TV Installation and Service!
Here are some tips and products to keep your displays, cell phones and remotes controls streak-free and spotless.
With spring just around the corner, it’s time to clear away the cobwebs and get your house back in shape.
In addition to windows, walls and floors, your spring cleaning project should also include TV screens, iPods and remote controls.
What’s the best way to de-grime them? Here are a few products we’ve run across as well as tips from custom electronics professionals.
1. “Most cleaners—even soap and water—are either too harsh or leave water spots on the surface,” says Joshua Huffman of RG Convergence Technologies in Raleigh, N.C.
“Keeping this in mind, we use microfiber cleaning cloths from Blue Wonder.” They’re a little pricey at $6.50 a cloth [check site for current price range], but they’re reusable and won’t scratch the surface of the screen (www.bluewondercloth.com).
2. You can protect your remote from gunk build-up by fitting a clear cover over it. If your kids’ messy hands to find the remote, you can easily wipe away the grime with a sanitary wipe or household cleaner.
3. Jayson Small of Adobe Cinema & Automation, Mashpee, Mass., recommends laying an anti-glare film ($15 from the Apple store) on the screen of your iPod, iPhone, iPod touch or iPad. “This will protect the screen from scratches and can easily be cleaned with a dry or slightly damp microfiber cloth.”
4. Most of us have gone through a cell phone or two due to water damage. A product called the Bheestie Bag ($20, www.bheestie.com) promises to dry out electronic devices. You just take out the battery, drop the device into the bag and let it sit overnight. The company says it can be used for products such as iPods, too. Water absorbing beads pull out the moisture. Does it work? We haven’t tried it, so we’d love to hear from someone who has. Email us.
