• The most expensive Grundig HiFi receiver of all time. Stereo sound in 1 or 2 rooms. SQ matrix quadrophony. And this is how the trade press judged it: "A top-class receiver with first-class reception performance and excellent amplifier operation, future-proof thanks to mono, stereo, quadro-matrix and quadro-discrete technology" (STEREO).

This proven top-of-the-line Hi-Fi control unit combines a high-quality broadcast receiver section and four complete, separate LF amplifiers (from input to output). This is a particular advantage if you want to provide optimum sound reinforcement for a large room or 2 separate rooms. You can control the volume and timbre of two pairs of speakers completely separately. In quadrophonic mode the RTV 1040 offers a For stereo playback in two separate rooms, 2 x 40/25 watts music/nominal power each.

1. operating mode: stereo Stereo playback is possible in one or two separate rooms. The volume, the sound (bass and treble) and the balance can be adjusted individually for each room.

2nd mode: Quadro-Matrix Playback of Quadro programmes using the SQ matrix or similar method via record, 2-track tape or cassette, or VHF. All stereo programs can also be played back in quasi-quadraphony (similar to 4D).

3rd mode: Quadro-Diskret Playback of 4-track Quadro-Diskret tapes when a 4-channel tape machine is connected. Playback of records using the CD 4 or similar method (only in conjunction with Grundig CD 4 quadro demodulator and specially designed record player).

Operating convenience: Fully electronic VHF program selection via 8 pulse fields by GRUNDIG impuls-electronic. Console-shaped "cockpit" with 7 easy-to-read illuminated instruments and display fields. Triple light panel for automatic display of stereo, quadro-discrete and quadro-matrix. Grundig Super-Tunoscope for exact tuning to station centre on FM and transmission of selected stations from the main dial to individual FM pulse fields, coupled with still tuning. 10 flat-panel controls with exceptionally wide adjustment range for optimum tone control, separately for volume, bass, treble, stereo balance (left/right) and quadro balance (front/rear). Disengageable, aurally correct volume control (Conour/Linear button.) Buttons for silence tuning and noise. Connections for TA magnet and crystal, 2 further connections for TA/TB stereo or Quadro front/rear. Connections according to DIN 45 327 for 2 stereo or 1 quadro headphones. Switchable connections for 3 speaker pairs (4 Ohm).

Receiving section: 4 ranges: U, K (19...55 m), M, L. VHF mixer section with push-pull tuning by capacitance diodes and bandpass filter preamplifier in special circuitry for processing high antenna input signals. High selectivity due to 4 IF stages with 2 highly selective 4-fold bandpass filters. An electronic delay for VHF suppresses unwanted stations during switch-on. Switchable automatic VHF sharp tuning with illuminated display. Stereo automatic decoder in modular technology. VHF field strength indicator instrument, for AM as tuning indicator.
