Annoying Loud Commercials?

Often people have complained about volume changes between channels and loud commercials, particularly when watching the HDTV feeds of their local stations. The reason behind this is a lack of people at the stations to be able to monitor both the analog transmissions as well as the digital transmissions. Additionally, the equipment to automatically normalize the sound is much more expensive than what is required for an analog signal and many, if not most, stations do not have equipment to automatically set the volume as sources are switched.

At home this annoyance can be corrected. The least expensive method would be to use the stereo analog audio connection and run the audio signal through an automatic volume controller on the way to the TV set or A/V receiver. Such a device would be the Audiovox/Terk VR-1 priced at under $50 at most dealers, under $30 at amazon.com, see link. You can search on eBay for a source or go here: AUDIOVOX (TERK) VR-1 TV VOLUME REGULATOR for a reliable etailer.

Another benifit of this device is to bring up the volume on stations that brodcasts with low volume levels as well as to bring down the volume of stations that broadcast their audio too hot. The Terk device will decrease the volume on high signals and increase the signal on low levels. See the signal into your TV set should be at the 1 volt nominal level. That’s what that device does. Sets its output to 1 volt nominal no matter what the input is.

IR Commands For Components Inside Cabinets

More and more people are putting their components inside cabinets or in a closet where the line of sight IR remote controls do not work. What can be done?

The answer is to get an IR Distribution System.

The IR distribution system consists of a sensor you place in a position that your IR remotes can hit and remote IR emitters or IR blasters that provide the IR signal repeated for the equipment inside your cabinet or closet. One such system is shown to the left.

Transferring Recordings From HD Receiver to a PC

Many times the question comes up if HD video can be transferred out of a HD receiver and into a PC.

The answer is yes.

169time.com has a firewire modification available that will allow you to dump the HD files to a firewire equipped PC. Once in the PC then format conversion could be made to allow recording to DVD or played by players or cards that use a different format. Only order this item if you have a compatible receiver or decoder. Hughes HTL-HD & HIRD-E86 & HIRD-E8, Mitsubishi SR-HD5 & SR-HD400, Toshiba DST3000, Sony SAT-HD200 & SAT-HD300, Zenith DTV1080 & HD SAT520, LG LSS3200A Phillips DSHD800R, RCA DTC100*, Proscan PSHD105*, DishNetwork & BellExpressVu 6000*, GI/ Motorola HDD200* for 4DTV or Starchoice, Integra 912S & 815, Unity Motion HDR-1000A.

Slaving A Second TV From A HD Receiver

 

Many people have used their satellite receiver’s RF output to run to a remote TV. And when they get a new HD receiver they find there is no longer a RF output available to connect the coax run to the remote TV. What to do?

There is another way to solve this. Get a RF modulator to feed the coax like the one in the link to the left. That unit by Monster will connect to the HD receiver via a s-video cable for the video and a stereo audio cable for the audio.

Now there is one caveat with this hookup.  Many HD receivers will need to have their output format set to 480i in order to enable the SD outputs. Known receivers are the H20, HR20 and the TiVo Directv receivers. This complicates the issue slightly in that in order to watch the remote TV the format must be reset to 480i first. Obviously the main TV will not longer display a HD picture with the format set for 480i and on some HDTVs the 480i is not supported through the HD inputs. You will end up with a one or the other situation.  If your receiver fits this case, it may be better to add a SD receiver for the remote TV.

Another possibility would be to use a wireless system like the one to the left.  They basically hook up to the receiver’s A/V outputs (Yellow-Red-White) and to the remote TV’s A/V inputs.  If your remote TV does not have A/V inputs then this will not work unless you add a RF modulator at the remote TV, but most SDTVs have an A/V input.

Are you having OTA Signal Problems?

 

Often you have installed an antenna to get your HD over the air only to find that some of the stations will almost work. If you are experiencing drop outs and your station will not lock in, then a good low noise mast mounted preamp may be just what you need.

These units have the preamp mounted outside near the antenna to insure that there is not any noise picked up by a long lead in cable. Then you put the power supply inside the house and it will feed power up to the preamp through the coax cable. RG6 coax is recommended.


Once the signal is down from the antenna a lot of signal loss can be induced by splitters. Another approach instead of splitters is to use a

Are You Out Of Inputs?

HDMI

It seems like there can never be enough inputs on equipment these days. Many low cost home theater receivers will only have a single optical digital audio input and many HDTV will come up short on the number of HD inputs. With the possibility of a satellite or cable receiver, a DVD, a HD DVD and possibly a game console all HD capable with digital audio, inputs get used up quickly. Often a separate A/V switch box is the answer. The unit shown to the left is a very good value in that it will not only switch component video sources, but optical audio sources as well. A single solution for the lack of inputs on the TV as well as a lack of inputs on the surround processor. Need to switch the stereo audio connections to the TV as well? This unit will do that too.

What if you need several HDMI inputs? There are HDMI switches as well like the unit to the left. The thing you want to look for is a unit that comes equipped with a remote or is capable of learning from a remote. Add one of these switches with a universal macro programmable remote, and you are on your way to an integrated system..

A/V Distribution Wiring

Key Digital has come out with a new line of baluns to ease the wiring of Audio/Video systems. These can be used to provide component video to projectors via a cat 5/6 cable rather than running 3 coax cables.

Alternately, for distributed satellite systems these baluns can be used to allow the central mounting of satellite (or cable) receivers in an A/V room (or closet) with the TVs being located in a remote location. An example of this is an automobile dealership we just completed where we had 7 satellite receivers mounted in the computer server-A/V room. This room was used for all of the telephone equipment, the computer servers, the network hub for all of the workstations, the paging system and the A/V receiver equipment. We used a Key Digital KDCAT5XRCA CAT5 Video/Audio Balun with RCA Connectors at the receivers connected via cat5 to Key Digital KDC5CWP CAT5 Video/Audio Balun Wall Plate with RCA Connectors at the TVs. See photos at the end of the post.

That got the A/V signals distributed. Next there is the need for the IR to be sent back from the TV area to the satellite receivers. For this we used 2 Niles Audio MSU440Z for 8 zones to cover the 7 satellite receivers. They mount in the rack with the satellite receivers and have a Niles MF1 - IR flasher (IR emitter) attached to each of the satellite receivers. Notice the emitters come with a shield that can be applied over the emmiter to prevent the IR signal for one receiver interfeering with another. Finally, at each TV there is a Niles Audio MS200 Miniature Surface Mount IR Sensor ( Black ) that is wired back to the zone controllers in the A/V rack via another cat5 cable. We used a blue cable for video and a white cable for the IR sensors wired per the Niles suggestions.

Other applications for these baluns would include a method for whole house HDTV A/V distribution system. Combined with matrix switchers and Home Theater PCs for DVRs, a whole house DVR is also well within the possibilities.
