Special Audio - DirecTV HDTV User Manual

Adjusting TV Controls
Audio Output Displays a choice list of available audio output modes, which
determine how volume will be controlled through the output jacks.
• Fixed Output Fixed audio mode provides a fixed output control level from
the TV's audio output jacks to an external device such an external sound
amplifier. With the fixed audio mode, the TV's volume control, tone controls,
and mute are disabled. You must use the amplifier's remote control to change
volume.
• Variable Output Variable audio mode allows a variable output control level
from the TV's audio output jacks. If the volume changes on the TV via the
volume buttons on the remote control or front panel, the output volume
changes as well.
Sound Check Tests the front, rear, and center speakers to make sure all channels are
working and are properly connected to the correct speakers.
Front Balance Allows you to adjust the sound balance between the left front and right
front channels.
Rear Balance Allows you to adjust the sound balance between the left front and right
rear channels.

SPECIAL AUDIO

Audio Processor Displays a choice list of available audio modes, which control the
way the sound comes through your speakers. Depending on your speaker setup, any
combination of the following options will appear:
• Mono Plays the sound in mono only, and outputs sound from the front left and
right speakers only. This is a good choice when receiving broadcasts where
distance from the broadcasters makes the stereo signal weak. The channel banner
displays the word Mono when you tune to a program that is broadcast in mono.
• Stereo Splits the incoming stereo audio signal into left and right front channels.
Most TV programs and recorded materials have stereo audio. The channel banner
displays the word Stereo when you tune to a program that is broadcast in stereo.
• Dolby 3 Splits the incoming audio signal into front left, right, and center
channels. The channel banner displays the words Dolby Digital when you tune to a
program that is broadcast in Dolby Digital.
• Pro Logic Splits the incoming audio into left, right, center, and rear channels. You
must connect rear speakers to hear the rear (surround) channel sound. This is a
good choice for movies and TV programs broadcast in Dolby Surround.
• Hall Surround Splits the incoming audio signal into left, right, and rear channels.
Extra delay is added to the rear channels to simulate a concert hall sound effect.
• Matrix Surround Splits the incoming audio signal into left, right, and simulated
rear channels. You must connect rear speakers to hear the rear (surround) channel
sound. This is a good choice when you're listening to monophonic audio, such as
speeches, sporting events, or plain dialog and wish to have sound coming from all
channels.
