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.

Remarks

• The Sansui QS-100 contains two power amplifiers, a decoder for matrix-encoded records and a synthesizer for quadrophonic processing of normal stereo signals.
• If you add the QS-100 to an existing stereo receiver amplifier, this combination offers the same possibilities as a full-fledged quadro amplifier with regard to all types of quadrophony.

• Sansui QS-1
