  • Notes

  • A hi-fi stereo integrated amplifier housed in a black or champagne gold metal case with wooden side panels, with power output of 105 watts FTC per channel into 8 ohms or 135 watts FTC per channel into 4 ohms. Copper plated chassis, Quarter A MOS FET output (class A output up to 25 watts, then class AB), AVSS (Automatic Voltage Shift Supply) enables the amplifier to respond to the wide dynamic demands of digital signals. With rotary controls for left and right Bass and Treble, Volume and Balance, rotary switches for Selector (CD, Phono, Tuner, TV/Aux1, Video/Aux2), Phono (MM, MC (High), MC), Tape Copy (Hi-Fi VCR⇾1/2, Source, 1/2⇾Hi-Fi VCR), push button switches for Speakers 1, 2, Tone Defeat, Tape Monitor (Source, Tape1, Tape2, Hi-Fi VCR), Muting, Subsonic Filter, Mono, CD/Phono Direct and a jack for Headphones. With RCA phono sockets for Phono (MM or MC), CD, Tuner, TV/Aux1, Video/Aux2, for input/output Tape1, Tape2, Hi-Fi VCR, terminals for 2 pairs of loudspeakers and 3 AC outlets.
