JVC TRS-1004
The JVC TRS-1004 is a test record. It's a vinyl LP pressed with specialized tones and signals for adjusting and evaluating phono cartridges. JVC made several test discs during the 1970s, when LP records were at their peak and the new CD‑4 quadraphonic system demanded careful cartridge setup.
Not much is documented about the TRS-1004. What exists comes from its use as a reference tool in contemporary equipment reviews. Audio (September 1975, p.63) said a good CD‑4 cartridge should produce more than 0.7 mV at 30 kHz from the TRS-1004, where a 30 kHz monophonic signal is recorded at the 5.5‑inch diameter. The same review listed the disc alongside the JVC TRS-1005, Stereo Review SR‑12, and B&K QR‑2009 among the test records used in their lab. Audio (November 1975, p.70) listed the TRS-1004 again, in a battery of test records used to measure a Phase Linear preamplifier and Crown amplifiers. A later Audio article (June 1981, p.69) mentioned that band 12 of the TRS-1004 produces 370 Hz, used in a test of the Shure MV30HE cartridge. Studio Sound (May 1982, p.51) described it as "record for quick checks of HF response, crosstalk, and phase of CD‑4 cartridges."
Outside the magazine labs, the only other trace is a listing on a Japanese test‑record collector's page, where it is given the alternate number RG‑1392. No release year, original price, or full track listing has surfaced.
