Audio Options for HDTV
HDTV inherently provides a superior sound quality simply because
the sound of HDTV is digitally transmitted. The difference in
sound between an HDTV television and an analog television is
rather noticeable. In fact, it is directly analogous to the
difference between the music on CD's compared to the music on
audiocassette tapes.
The difference in sound quality provided by HDTV televisions and
programming does not end there. Many HDTV programs are also
broadcast in Dolby Digital 5.1 surround sound, but in order to
take full advantage of this technology, it is necessary to have
the right equipment.
Dolby technology has been created by Dolby Laboratories, Inc.
This technology is the most renowned provider of digital audio
technology. Also, Dolby Laboratories is known for reliable and
superior products. For these reasons, Dolby Digital Surround has
become the standard for HDTV. Many television manufacturers
substitute their own surround sound systems, but they cannot
live up to the reputation and performance of Dolby. Therefore,
it important to check the specs on an HDTV television before
buying in order to ensure that it uses Dolby Digital Surround.
When using Dolby Digital Surround Sound, there are three options
for set up. The first option is to buy a television with high
quality center channel speakers, woofers, tweeters, and Dolby
technology installed in the television. With this option, it is
unnecessary to buy addition equipment to take advantage of Dolby
Digital Surround Sound.
Another option for taking advantage of the Dolby Digital
Surround Sound with an HDTV is to connect an external set of
surround speakers to the television. With this option, the
surround sound set up includes a front pair of speakers, a
surround pair of speakers, a center channel, and a subwoofer.
Sometimes, the front speakers are "powered towers." This means
these towers include subwoofers.
The placement of these speakers is very important for the
quality of the surround sound. The Center Channel Speaker should
be centered either above or below the television. The Front Left
and Right Speakers should be placed in an arc formation in line
with the Center Channel Speaker. The Surround Left and Right
Speakers, on the other hand, should be placed to the left and
right sides behind the listening position. Many people choose to
wall mount these speakers.
The third option for taking advantage of the Dolby Digital
Surround System included in an HDTV television is to use an
external set of front speakers can be connected to the HDTV
television. This configuration is useful if there is not enough
room to set up the external surround sound system and the HDTV
does not come with Dolby Digital Surround installed. This isn't
true surround sound, but it is a viable alternative to those who
can't take advantage of the first two formats.
The audio and video outputs of the DVD or VCR can be connected
to the AV receiver's video outputs. If a separate DVD and VCR
need to be connected, one can be connected to the VCR1
connection and the other can be connected to the VCR2
connection. The AV receiver's VCR video and audio outputs should
then be connected to the audio and video inputs of the DVD
and/or VCR. In this way, the DVD and/or VCR will be able to
record video signals that come through the AV receiver and the
VHS tapes and/or DVD's will be able to be viewed on the HDTV.
To take full advantage of the Dolby Digital Surround Sound
technology, one of the video outputs of the DVD player and/or
VCR needs to be connected to the AV receiver. The digital
coaxial audio or digital optical connection must also be
connected to the AV receiver.
How do I connect my CD player?
A CD player can be connected to an AV receiver. The CD player's
digital audio outputs can be used to connect the CD player to
the AV receiver. A CD-Recorder can also be connected the AV
receiver by using the Audio Tape Record/Playback input/output
loop connections. In this way, the CD-Recorder will be able to
function much like a standard audiocassette deck.
What else will I need?
Besides the basic electronic equipment needed to set up Dolby
Digital Surround Sound, it is necessary to have connection
cables. This includes video, audio, and loudspeaker connection
cables. These cables need to be at an appropriate length in
order to set the speakers in the proper position for optimal
surround sound quality.
