Question

The question is based on the quote from the manaul:

"Power User Tip:

Use these outputs in conjunction with ADAT input(s) to expand the analog outputs of your audio

interface for monitor mixing or speaker switching. By wiring the ADAT output to the ADAT input, you can also use

the DAC and Direct Analog Outputs to create an analog split of your eight input channels. See Section 2.3.3."

/Thank you

Answer 1

The DB25 Direct Outputs are "post" Direct button which dictates the audio source.

The DB25 DAC Outputs are "post" converter.  The converter is also "post" Direct button.

Therefore if you were using the DP88 stand alone, you could connect ADAT cables from the OUTS to the INS if you wanted to use both DB25 Direct Outputs and DAC Outputs at the same time.

Thus "splitting" the 8 input channels to 2 sets of 8 outputs.
