Audio Research Reference 80S Silver - Skyltexemplar
Specifications
POWER OUTPUT 70 watts continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 1% at 140 watts (33 watts in Triode mode) per channel, below 0.04% 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 critical)
POWER BANDWIDTH (-3dB points) 7Hz to 68kHz
FREQUENCY RESPONSE (-3dB points at 1 watt) 0.7Hz to 94kHz
INPUT SENSITIVITY 1.4V RMS Balanced for rated output. (25.5 dB gain into 8 ohms); 0.7V RMS SE for rated output.
INPUT IMPEDANCE 300K ohms Balanced, 75K ohms Single Ended
OUTPUT POLARITY Non-inverting. Balanced input pin 2+ (IEC-268)
OUTPUT TAPS 16 ohms, 8 ohms, 4 ohms
OUTPUT REGULATION Approximately 1.0dB 16 Ohm Load to Open Circuit (Damping factor approximately 8)
OVERALL NEGATIVE FEEDBACK 15dB
SLEW RATE 10 volts/microsecond
RISE TIME 4.0 microseconds
POWER REQUIREMENTS 105-130VAC 60Hz (210-250VAC 50Hz) 420 watts at rated output, 280 watts in Triode mode, 221 watts at “idle”, 3.6 watts off Units for Japan: 100VAC 50/60Hz
TUBES REQUIRED 2 matched pair KT150 (Power output V1-V4); 2 6H30 (Gain stage V5, V6)
