3.5.7 The
Audio Out (AES)
group
This group provides additional audio processing
for the 4 discrete AES outputs.
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 outputs 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.
Level (dB)
: -96 to 0 dB in 0.5 dB steps: sets an attenuation level to the channel source. For non-PCM
audio, the level value is overridden to 0 dB.
