Specifications
POWER OUTPUT:
75 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic
distortion typically 1% at 75 watts, below 0.05% at 1 watt. (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 80kHz.
INPUT SENSITIVITY: 1.4V RMS BAL for rated output. (25dB Bal gain into 8 ohms.)
INPUT IMPEDANCE:
300K ohms Balanced (150K ohms SE).
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 CIRUCIT
(Damping factor approximately 8).
OVERALL NEGATIVE FEEDBACK:
15dB
SLEW RATE: 10 volts/microsecond
RISE TIME:
4.0 microseconds
CHANNEL SEPARATION:
112dB
HUM & NOISE: –84dBV weighted, 8 ohms tap
SIGNAL TO NOISE:
112dB
CONTROLS: Power on/off, auto shut-off on/defeat, Input BAL/SE, RS232, 12V trigger
