OTHER MAC OS X AUDIO SOFTWARE

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:

Outputs are similarly listed in the same order as

follows:

As an example, the AES/EBU inputs will always be

listed as inputs 9-10. As another example, optical

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 optical

outputs 1-2 would be listed as channels 13-14.

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 896HD) to your

computer. This input serves, for example, as a

convenient way for you to record the 896HD’s

MIX1 monitor mix 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 MIX1 stream being sent to the

computer. For details on how to do this, see “Mix1

Return Includes Computer” on page 96.

The Mix1 1-2 input is not available at the 4x sample

rates (176.4 or 192kHz).

☛ War ni n g : t h e Mix1 1-2 input can cause

feedback loops! DO NOT assign this input to a

track that shares the same 896HD 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 18 inputs and 22 outputs provided by

your 896HD — although the number of channels

may depend on how your 896HD is conﬁgured:

■ 12 channels for analog I/O (including the

headphone out)

■ 2 channels for AES/EBU

■ Zero or 8 channels for optical, depending on

whether you have optical turned off or set to ADAT

optical

For example, if you are using analog only, the

896HD requires a minimum of 12 voices (for 12

channels of output). If you are using analog and

AES/EBU, you need 14 voices.

As another example, if you are using analog,

AES/EBU and ADAT optical, you need 22 voices

(the maximum number of simultaneous output

channels provided by the 896HD).
