MONAURAL MODE SPECIFICATIONS
Power Output: (Refer to Figures 14 and 15.)
400 Watts continuous average sine wave power into
16 ohms with less than 0.05% THD, 20Hz to 20kHz.
Frequency Response: (Refer to Figure 16)
+0dB, -1dB, 20Hz to 50kHz.
Total Harmonic Distortion : (Refer to Figures 17 and 18.)
Less than 0.01% @ 300 Watts into 1 6 ohms at 1kHz.
Intermodulation Distortion:
Less than 0.05% using frequencies of 70Hz and 7kHz,
mixed in a ratio of 4:1, at a power output of 200
Watts into 1 6 ohms.
Input Sensitivity:
An input of 0dB (0.775 Volts), ±0.5dB, produces an
output of 200 Watts into 1 6 ohms (INPUT attenuator
set for minimum attenuation, maximum level).

Damping Factor: (@ 16 ohms) (Refer to Figures 19
and20).
Greater than 220 at any frequency from 20Hz to
1kHz; greater than 100 at any frequency from 20Hz
to 20kHz.
Hum and Noise:
At least 110dB signal-to-noise ratio (I.H.F./A.S.A.
No. Z24.3-1944).
Slew Rate:
35 volts per microsecond, or better, at 100 Watts into
1 6 ohms, 200kHz square wave input.
