The RTV 1040 Q Hi-Fi, also known as "Quadro-Receiver" is a tuner amplifier with quadraphonic (SQ Matrix) sound reproduction. It comes with four Audiorama 4000 globe speakers, and a Garrard Zero 100 SB transcription unit. It had one of the most powerful amplifiers in its time providing 160-watts music power (4 × 40-watts) in quadraphonic mode. With four completely separate audio amplifier circuits, it is capable of Quadro Discrete playback of CD4 (with optional decoder), or Quadro Matrix, signal sources.

  1. Quadro Discrete Operation is for playback of 4-track quadro tape recordings or discs recorded to the CD4 system, which requires a special pick-up and CD 4 de-modulator.
  2. The Quadro Matrix Operation is a different type of system for reproducing quadraphonic material from SQ Matrix discs or tape. In addition, this amplifier also provides the Grundig 4D system for pseudo-quadraphonic playback.

This unit has a differential amplifier, with outputs free of electrolytic capacitors ensuring excellent linearity. The power output stage had electronic overload protection, and thermal protection.
