(Center, Sub, Ls, Rs). When the PRE button is engaged, Aux Sends 7 and 8 are fed pre-fader.

This provides independent control when a channel is also assigned to the Program Bus.
The Echo Returns can be used to return additional channels from the DAW, returns from virtual

instruments, returns from outboard effects processors, or any other line-level source. If the

Echo Return 500 slots are fitted with the 550A Discrete 3-Band EQ, 550B 4-Band EQ, 560

Graphic EQ and/or 525 Compressors, the audio returning to the Echo Returns can be further
processed before contributing to the mix.

Echo Returns are assigned to contribute to the mix in the same manner as with the channels for
both stereo and surround mixing. Engage the PAN button to enable the pan-pot.

Outboard Effects Processor Connections

The diagram below shows the connections between a 1608 and outboard effects processors for

either mixing scenario above. Returning the outputs of the outboard effects processors to the

Echo Returns Auxiliary Inputs allows easy switching of the Echo Return input source between
the return of the DAW (main input) and the return from the effects processor (Aux Input)

without changing connections on the rear panel.
