  • Annotazioni

  • A hi-fi stereo integrated amplifier housed in a black case (or silver case, W Germany only) with continuous average power output of 2 x 60 watts into 8 ohms (2 x 70 watts into 8 ohms DIN). Anti-vibration construction with honeycomb chassis and heat sink. With MM and MC cartridge phono equalizer. With Bass and Treble tone controls, Direct, MM/MC selector, Loudness, Subsonic filter, Muting, Speakers (A,B,A+B) and a jack for headphones. With RCA phono sockets for input Phono, Line, Tuner, CD, for input output DAT/Tape1, Tape2 and Adaptor (I/O connected by removable links), and terminals for 2 pairs of loudspeakers. The General Export (SD) model also has 3 AC outlets.

    Same as the later Pioneer A-449 Integrated Stereo Amplifier apart from appearance.
