SANSUI VINTAGE AMPLIFIER ( Working )

Sansui Model: QS-500 Type: Quadrophonic decoder amplifier Years of manufacture: 1(contact info removed) Made in: Japan Color: front aluminum brushed silver / black, wooden cabinet Remote control: no Power consumption: Dimensions: 382 x 162 x 337 mm (WxHxD). Weight: 10 kg Original price approx.: 1'680 DM Connections Number of inputs: 2-channel: 100 mV / 60 kOhm 4-channel aux: 100 mV / 120 kOhm 2-/4-channel tape monitor: 200 mV / 120 kOhm Number of outputs: 2-/4-channel Tape Out: 100 mV RCA 2-/4-channel Tape Out: 20 mV Din Pre Out: 1V, max. 3V 2 pairs of speakers (rear) Technical Data Continuous power (rear speakers) 8 Ohm: 2x 33 W (20 - 20'000 Hz), 2x 36 W (1 kHz, 1 %) 4 Ohm: 2x 47 W Dynamic power 8 Ohm: 4 Ohm: 2x 60 W Total harmonic distortion: <0.5% Attenuation factor: 40 Frequency response: 20 - 40'000 Hz 2-channel Tone control: Bass: -11/+12 dB (at 100 Hz). Treble: -10/+9.5 dB (at 10 kHz Special Features: 4 VU meters Switch for 4-channel RM, SQ, Discrete / Stereo / Mono CD-4 connectable Synthesizer decoder function selector for: Concert Hall 1 and 2: stereo signals pseudo-square processed. Surround: pseudo quadraphonic stereo signals, except that the listener is placed in the center of the musical action. The channels can be cyclically swapped by 90 and 180 degrees clockwise (Right Quarter Turn and Half Turn) In the "Decoder" position, matrix-encoded records, preferably QS records, are listened to. Note : 2 lights from the VU meters are blown Remarks The Sansui QS-500 contains two power amplifiers, a decoder for matrix-encoded records and a synthesizer for quadrophonic processing of normal stereo signals. If an existing stereo receiver amplifier is supplemented by the QS-500, this combination offers the same possibilities as a full-fledged quadro amplifier with regard to all types of quadrophony.
