Number Of Channels - MOTU 828mkII User Manual

Most programs will likely address this issue in
future updates. In the meantime, here is how you
can identify each input and output. Inputs are
always listed in the same order as follows:
Input Channels
Mic-Guitar 2
Analog 8
SPDIF 2
Mix1 2
ADAT 8 @ 44.1/48kHz
4 @ 88.2/96kHz
Outputs are similarly listed in the same order as
follows:
Output Channels
Main outs 2
Analog 8
SPDIF 2
Phones 2
ADAT 8 @ 44.1/48kHz
4 @ 88.2/96kHz
As an example, Analog inputs 7-8 will always be
listed as inputs 9-10. As another example, ADAT
output channels 1-2 will be listed as channels
15-16, unless the phones are mirroring the main
outs (or another output), in which case ADAT
outputs 1-2 would be listed as channels 13-14.

13-14 If the phones are
assigned to mirror
another output pair
(such as the main
outs), they won't be
listed separately.
15-22 If the phones are mir-
15-18 roring, then subtract
2. If the optical bank is
set to TOSLink or
None, then no ADAT
outputs are displayed.
The 'Mix1' input pair
The Mix1 input pair delivers the output of CueMix
DSP "MIX1" (the first mix bus of the four on-board
no-latency monitor mixes in the 828mkII) back to
your computer. This input serves, for example, as a
convenient way for you to record the 828mkII's
MIX1 monitor mix back into your host audio
software (for reference and archiving purposes).
Further, if you are sending audio from your host
audio software to the same output pair as MIX1,
you can choose to either include or exclude the
audio from the computer in the stream being sent
back to the computer. For details on how to do this,
see "Mix1 Return Includes Computer" on
page 100.
☛
Warning: the Mix1 1-2 input can cause
feedback loops! DO NOT assign this input to a
track that shares the same 828mkII output pair as
MIX1.

NUMBER OF CHANNELS

If your host audio software requires that you
specify the number of audio voices or channels you
will be using, be sure to choose enough channels to
cover the 20 inputs and 22 outputs provided by
your 828mkII — although the number of channels
may depend on how your 828mkII is configured:
12 channels for analog I/O (including the
■
headphone out)
2 channels for RCA S/PDIF
■
Zero, 2 or 8 channels for optical, depending on
■
whether you have optical turned off, or set to
S/PDIF or ADAT optical
For example, if you are using analog only, you only
need 12 channels. If you are using analog and RCA
S/PDIF, you need 14 channels.
