Power Output: 75 watts per channel continuous from 20Hz to 20kHz. 1 kHz total harmonic distortion typically 1.5% at 75 watts, .05% at 1 watt. Approximate actual power available at “clipping” 80 watts (1kHz). (Note that actual power output is dependent upon both line voltage and “condition” i.e.: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)


Power Bandwidth: (-3dB points) 12Hz to 70kHz.
Frequency Response: (-3dB points at 1 watt) 1.0Hz to 70 kHz.

Input Sensitivity: 0.55V RMS Single-ended for rated output. (32.5dB gain into 8 ohms.)

Input Impedance: 52.5K ohms Single-ended.

Inputs (5): 1, 2, 3, 4, 5 (Single Ended RCA connectors).

Maximum Input: 10V RMS (any input).

Output Taps: 8 ohms, 4 ohms.

Output Regulation: Approximately 2dB 8 ohm load to open circuit (Damping factor approximately 4).

Overall Negative Feedback: 4dB.

Slew Rate: 10 volts/microsecond.

Rise Time: 4 microseconds.

Hum & Noise: Less than 1.0 mV RMS -88dB below rated output (IHF weighted, Vol down).

Power Supplies: Electronically regulated Low and High voltage supplies for input stages. Automatic 40 sec. warm-up/brown-out mute.

Power Supply Energy Storage: Approximately 350 joules.
