The Calyx is an asynchronous USB DAC capable of receiving up to 24bit/192kHz data via either an asynchronous USB or regular coaxial S/PDIF input.
The Calyx uses an 8 channel Sabre ES9018 32bit DA converter, 2 channels for each phase of the signal per channel, resulting in a fully balanced signal from the converter to the outputs.
As well, the Calyx DAC has two separate clock generators, one for 44.1/88.2/176.4kHz and one for 48/96/192kHz data rates. Finally, the analogue output stage gives you the choice of unbalanced RCA or fully balanced XLR outputs. If you are using this with a computer the Calyx DAC will take power from the USB bus or an optional 5V power supply.
