Inputs for Tuner, Tape, Aux 1, Aux 2 and Phono (optimized for Shure V15 II). Sensitivity phono: < 5 mV, signal-to-noise ratio 84 dB (referred to 1 V output). Sensitivity other inputs: < 1 V at 100 k. Signal-to-noise ratio of power amplifier 100 dB (compared to max output). THD < 0.01% from 2 mW output to max. power at all frequencies. Volume control with dual precision attenuator, 60 dB range, 2 dB steps. Eliminates need for separate balance control. Tone controls (treble, bass, range +6 to -6 dB) Stereo/stereo reverse/mono L/mono R, dual mono operation also possible (separate use of each channel) Noise filter: corner frequency 5 or 8 or 20 or 100 kHz, 18 dB/octave, with 30 dB notch at 10 kHz in the 5 and 8 kHz positions NB Barney (Dr. Bernard M) Oliver was HP's vice president for research and development, and the designer of this amplifier.
