AQD - ATSC/QAM Demodulator
OUTPUT VOLUME:
The output volume can be adjusted within
a range of 0 to 100%.
AUDIO MODE:
The audio mode command allows for the
selection of mono or stereo audio.
➣
NOTE:
It is extremely important to change the AUDIO MODE
to mono if using a non-stereo (mono) modulator in conjunction
with the AQD unit. This will present the full combined mono
audio output on both RCA connectors.
CC:EIA-608:
This is the Closed Captioning command mode.
The closed captioning, also known as line 21 captions is per EIA-
608, the standard for Closed Captioning for NTSC Broadcasts
in the United States. An operator can globally enable or disable
closed captioning for each module eliminating the need to adjust
individual TV viewing locations.
AQD PWR RESET:
The AQD Power Reset command allows an
operator to reset the power or "cold boot" an individual or all the
modules installed in a rack. To perform a reset for a single module
navigate to the AQD Power Reset command for that particular
module (the module number is displayed first on each LCD screen),
then press the Enter key, when the blinking cursor appears press
the up/down arrow keys to toggle to the YES entry, Press Enter to
select. A reset to all modules can be performed at any module reset
command screen.
