Benchmark DAC1 HDR - Digital to Analog Audio Converter
Discontinued, replaced by DAC2 series. XLR outputs feature passive output attenuators adjustable in 10 dB steps (0, -10, -20, -30 dB). Rear-panel switch selects Variable or Calibrated output. Headphone gain programmable at 0 dB, -10 dB, or -20 dB. Motor-driven Alps volume control with remote. USB input is USB Audio 1.1 (96 kHz / 24-bit). Coax and optical inputs likely support up to 192 kHz but exact max rate not explicitly confirmed on this page.
