Buying
a High Definition Television (HDTV)
What
Are My Audio Options for HDTV?
HDTV innately provides a greater sound quality
simply because the sound of HDTV is digitally transmitted.
The difference in sound between an HDTV television and an analog
television is quite noticeable. In fact, it is directly comparable
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, however, end there. Many HDTV programs
are also broadcast in Dolby Digital 5.1 surround sound, but
to take full advantage of this technology, it is necessary
to have the right equipment.
What is Dolby?
Dolby technology has been created by Dolby Laboratories, Inc.
This technology is the most recognized provider of digital
audio technology. In addition, Dolby Laboratories is known
for its 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 are hard pressed to live up to the reputation
and performance of Dolby. Therefore, it important to check
the specs on an HDTV television before purchase in order to
ensure that it uses Dolby Digital Surround.
What are my options?
When using Dolby Digital Surround Sound, there are three options
for set up. The first option is to purchase a television with
high quality center channel speakers, woofers, tweeters, and
Dolby technology installed in the television. With this option,
it is unnecessary to purchase 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.
How do I hook up my other entertainment equipment?
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.
