Lafayette LR-440
The Lafayette LR-440 was one of the first quadraphonic receivers on the market, and it was meant to make four-channel listening affordable. Introduced in early 1972, it combined an AM/FM stereo tuner with built-in SQ decoder circuitry. That let it play the then-new SQ-encoded quadraphonic vinyl records, plus discrete 4-channel 8-track cartridges and reel-to-reel tape. HiFI-Stereo (January 1972, p.25) announced it as “the first 4-channel AM/FM stereo receiver” with that decoding hardware on board. Outboard decoders were still common at the time.
Contemporary reviews treated the LR-440 as a good value. HiFI-Stereo (July 1972, p.35) called it “a lot of receiver for under $400” and praised its “sensible and useful design.” The same publication's October 1972 issue (p.46) ran a full bench test. Harmonic distortion measured between 0.05 and 0.06 per cent from 0.5 to about 22 watts per channel at 1 kHz. Intermodulation distortion fell from 0.3 per cent at 0.1 watt to 0.06 per cent. The reviewer noted that in FM distortion, quieting, selectivity, and AM quality “this receiver ranks very high by any objective standards,” and summed it up as offering “great operating flexibility at a moderate price without any serious sacrifice of performance.”
The LR-440 wasn't the most powerful quad receiver of its era, and it didn't pretend to be. It offered SQ decoding, four-channel tape playback and respectable measured performance at a price that put matrix quad within reach of more buyers.
