Specications
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 aected 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/o, auto shut-o on/defeat, Input BAL/SE, RS232, 12V trigger
AMBIENT AIR TEMPERATURE: 30° C (86° F) maximum ambient air temperature
POWER SUPPLY ENERGY STORAGE: Approximately 350 joules
POWER REQUIREMENTS: 100-125VAC 60Hz (200-250VAC 50Hz) 410 watts at rated output,
500 watts maximum, 230 watts idle. Sleep power < 1 watt
TUBES REQUIRED: 2 – Matched pair KT120 – Power Output; 2 – 6H30 Driver
DIMENSIONS:
