5.8.1 CH 1-2, CH 3-4, … CH 15-16 tabs, and AES1, … AES4 tabs
Each of these tabs provides all necessary controls for the
output mixers. The example shown is for 3G/HD Output, CH
1-2, but all panels have the same controls.
Operation Mode (Off, A, SUM(A+B), Mix): This menu allows
the source(s) 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 that in the Mix 4Ch
mode, if the Mute box is checked, only the even channel sources will be muted, the odd channel sources will still
pass to the output.
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

sources of the selected output channel.
Source A & Source B : These sub-sections allow the source channels (A and 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
channels 1-8) or one of two Dolby decoder modules installed on companion cards (A1 or A2 channels 9-16) to be
used as the source for this channel. Note: The ABUS card system is configured in the
ABUS panel.
Channel : Channel 1, …, Channel 16: selects the channel to be used from the selected audio source.

the level value is overridden to 0 dB.
