There is plenty of press out there to support the capabilities of this unit. I used it, primarily, for bass correction but in experimentation the DAC is very good. As detailed in the available information the combination of total room correction and USB DAC makes this one of the best bargains in audio. Only reason for sale is that I made a major change to my system and can no longer use this in the signal chain. Quick feature summary:
2 x RCA inputs or alternatively 2 XLR inputs
2 x RCA outputs and 2 x XLR outputs
Toslink S/PDIF digital input (2-channel PCM only)
Toslink S/PDIF digital output (48 kHz)
USB Audio (USB used also for measurement export and software update)
Microphone jack, power connector, DSPeaker Datalink
Two power supplies will be included - the base unit and the high-end external.
