3.4.7 The Audio Out (Video) panel
This panel provides additional audio processing for the 16 audio channels embedded in the HD/SD outputs:
audio channels mixing and audio embedding mode. The FRS-1801 may be paired with up to two DAP, AAP
or UAP cards for additional audio channel inputs to the mixers and for discrete AES outputs.
CH 1-2, CH 3-4, CH 5-6, CH 7-8, CH 9-10, CH 11-
12, CH 13-14 and CH 15-16 tabs
Each of these tabs provides all necessary controls
for the output mixers.
Operation Mode (Off, A, SUM(A+B), Mix): This
menu allows the source of each output channel to
be selected – a single channel, the sum of two
channels or a mix of two channels.
Off: The output channel is muted.
A: The output channel is the channel source
(ABUS Select and Channel) selected in sub-
menu SOURCE A.
SUM (A+B): The output channel is the sum of
the two channels sources (ABUS Select and
Channel) selected in sub-menus SOURCE A
and SOURCE B.
• If you select this option, the SUM (A+B)
Level pull-down is activated, allowing you to
reduce the level of the summed output (0dB, -3dB or -6dB).
Mix: The output channel is a mono mix of the (ABUS Select and Channel) selected in sub-menus
SOURCE A and SOURCE B.
Mix 4Ch: This mode allows a 3-input or 4-input mix on the chosen even
output. A standard 2-input mix is
available on the odd
output. On the same tab, the two selected sources of the even channel are mixed
with the one or two selected sources of the odd channel. The four sources are mixed, with the level of
each source adjusted using its slider or data entry box. You can swap the odd and even output by putting
a check mark in the Channel Swap (1&2) checkbox.
Note: in the case of SUM and MIX, if either of the two input channels is non-PCM, the output will always
be SOURCE A
Mute: Mute the audio channel by checking this box.
Source A & Source B: This sub-section allows the source channels (A&B) to be selected for each output
channel.
ABUS Select: V, A1, A2: selects the embedded input audio (V), one of two audio companion cards (A1
or A2) or one of two Dolby-E decoding modules installed on companion cards (A1 or A2 channels 9-16)
to be used as the source for this channel. Audio Bus is configured in the ABUS group.
Channel: Channel 1, …, Channel 16: selects the channel to be used from the selected audio source.
