Audio Research Reference 80S

De Audio Research  Reference 80S heeft dezelfde afmetingen als de 160S. Hij heeft evengoed hetzelfde niveau van ontwerp en techniek als zijn krachtigere versie.

enkele kenmerken:

• een fluisterventilator
• 4 KT150 buizen (ipv 8 bij de 160S)
• Ghost meters (Doorzichtige Vu meters)
• volledig gebalanceerde differentiële circuit topologie
• XLR en cinch-ingangen
• aparte aansluitingen voor 4, 8 of 16 Ohm luidsprekers
• 12 Volt in en uitgangstriggers
• RS232-ingang

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)
