$400 not bad I noticed this though....
The outputs of the ADC&DAC2000 are referenced to -10 dBu rather than the +4 dBu professional standard, which means the unit will be headroom-shy in a professional-equipment environment. That and the unbalanced outputs are doubtless the results of efforts to keep the price of the system low. On the other hand, ST Audio does make costlier external converter boxes that have balanced inputs and outputs.
Makes me think that I will need an adaptere to boost the levels and or balance the outputs..
