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 enabling 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: Mute the audio channel by checking this box. In
the MIX4Ch mode, checking this box will mute only the
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 selects the embedded input audio. This is the only choice available at this time.
Channel: Channel 1, …, Channel 16: selects the channel to be used from the selected audio source.
Level (dB): Sets the audio gain of the channel source from -96 to +12 dB in 0.5 dB steps. For non-PCM audio,
the level value is overridden to 0 dB.
