TECHNICAL SPECIFICATION

POWER OUTPUT

75 watts per channel continuous from20Hz to 20kHz. 1kHz total harmonic
distortion typically 0.6% at 75 watts, below 0.05% at 1 watt. Approximate
actual power available at ‘clipping’ 76 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) 7Hz to 60kHz.

FREQUENCY RESPONSE

(-3dB points at 1 watt) 0.7Hz to 75 kHz.

INPUT SENSITIVITY

1.4V RMS BAL for rated output. (25 dB Bal gain into 8 ohms.)

INPUT IMPEDANCE

300K ohms Balanced.

OUTPUT POLARITY

Non-inverting. Balanced input pin 2+ (IEC-268).

OUTPUT TAPS

8 ohms, 4 ohms.

OUTPUT REGULATION

Approximately 1.0dB 8 ohm load to open circuit (Damping factor approximately
8).

OVERALL NEGATIVE FEEDBACK

15dB.

SLEW RATE

10 volts/microsecond.

RISE TIME

4.0 microseconds.

HUM & NOISE

Less than 0.06mV RMS – 112dB below rated output (IHF weighted, input shorted).

POWER SUPPLY ENERGY STORAGE

Approximately 520 joules.

POWER REQUIREMENTS

105-125VAC 60Hz (210-250VAC 50Hz) 410 watts at rated output, 500 watts maximum,
230 watts idle.
