Mix 4Ch:
This mode allows a 3-input or 4-input mix on

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
