Item Measurement
Headphone impedance range 8 to 2,000 Ohms / 16 to 600 Ohms preferred
Power output (rms, both channels fully driven at 1% THD) 32 Ohms: 140mW/channel; 600 Ohms: 30mW/channel
Input sensitivity (for specified power output into 32 Ohms) 511mV rms
Input impedance 37k Ohms at max volume; 50k Ohms at min volume
Distortion (THD plus noise at 9 o’clock volume control setting (qtr power)) 10Hz-20kHz: better than 0.04%; 10Hz-1kHz: better than 0.02%
Frequency response (±0,-3dB) 10Hz – 35kHz
Output noise (22Hz-22kHz, quasi-peak/un-weighted) -95dB
Channel balance better than 1dB
Crosstalk Left to Right -56dB; Input to Input -68dB
Input selector centre-off position non-shorting; -38dB at max volume with 2V rms input (ref: 1kHz and 10kHz)
Output Stage Bipolar class AB
Supply voltage 24V DC unipolar
