Stereo Amplifier AU-9500

A stereo hi-fi integrated amplifier with output power of 75 watts per channel into 8Ω (115 watts per channel into 4Ω) with total harmonic distortion of less than 0.1%. With connections for  three pairs of speaker systems, headphones, two turntables, two tape decks, and inputs for tuner, microphone and aux. Sophisticated refinements are offered including triple tone controls with adjustable turn-over/roll-off frequencies, inputs for a 4-channel adaptor and a noise reduction adaptor, inputs for a 4-channel adaptor and a noise reduction adaptor, preamplifier outputs and power amplifier inputs, tape-to-tape copying facilities, and an audio muting switch. On the rear, 4 AC outlets.
