Specifications
Note: Power ratings based on a nominal power line input. All specifications are made
on the 8 ohm taps, utilizing an 8 ohm load unless otherwise specified.
Power Output: 110 watts continuous at 8, 4 and 2 ohms from 20 Hz to 20 kHz with less than 1% total
harmonic distortion terminated with rated load (typically <0.5% @ 110 watts 1 kHz) both
channels driven. Actual power output available at clipping (defined as <1% THD)
approximately 120 watts RMS
SMPTE Intermodulation
Distortion: <1% 20 Hz to 20 kHz @ 110 watts output
Power Bandwidth: 15 Hz to 90 kHz (-0.5 dB points)
(110 watt output) 5 Hz to 110 kHz (-3 dB points)
Frequency Response: 5 Hz to 40 kHz @ 1 watt (-0.5 dB points)
2 Hz to 120 kHz @ 1 watt (-3 dB points)
Input Sensitivity 1.25V RMS balanced for 110 watts output
(for 110 watt output): 1.25V RMS single-ended (inverting or non-inverting)
Input Impedance: 200K ohms balanced
100K ohms single-ended (inverting or non-inverting)
Damping Factor: >50 (determined using the IHF method from RS-490)
Output Impedance: 0.30 ohms at 1 kHz
Negative Voltage Feedback: 16 dB
Hum and Noise: approximately 400 microvolts of wideband, unweighted noise @ the 8 ohm taps,
input muted; -110 dB below a 110 watt output
Rise Time: 3.0 microseconds
Slew Rate: 16 volts/microsecond
Power Requirements: 110-120 VAC 60 Hz (220-240 VAC); 580VA at rated output, 650VA maximum
and 375VA with no signal input
Tube Complement: 8 (4 matched pair) x 6550C/KT88 - power output; 6 x 6922 - input/driver; 2 x 5687
