  • A hi-fi stereo integrated amplifier housed in a gold metal case with a black front, with continuous average power output of 2 x 100 watts into 8 ohms. With Bass and Treble tone controls, push button switches for Phono EQ, Loudness, ADPT1/TAPE3, Direct and Muting, rotary switch for Speakers (A,B, A+B) and Phono selector (MM, MC, MM Subsonic, MC Subsonic) and a jack for headphones. On the back, RCA phono sockets for input PHONO, TUNER, CD, and LINE, for input/output TAPE1/DAT, TAPE2, ADAPT1/TAPE3 and ADAPT2 (I/O connected together by removable links), terminals for 2 pairs of loudspeakers (A, B) and 3 100W AC outlets, two switched, one unswitched.

    Similar to the Pioneer A-777 Reference Stereo Amplifier (other markets).
