Benchmark DAC1 PRE - Digital to Analog Converter
Discontinued product, replaced by DAC2 Series. XLR outputs have passive output attenuators adjustable in 10 dB steps (0, -10, -20, -30 dB). Rear-panel switch selects variable or calibrated output mode. Headphone gain is programmable with 3 settings (0 dB, -10 dB, -20 dB). Left headphone jack has a programmable mute switch. Coaxial digital inputs likely support up to 192 kHz but exact max sample rate for coax/optical not explicitly stated on this page; 192 kHz is typical for DAC1 series S/PDIF inputs.
