What can I find out about the TTR-117 test record? It was called "Shure Audio Obstacle Course."
The TTR-117 was introduced in 1982 as a companion to the Shure V15-V phono cartridge. It was a 45 rpm record on a 12" disc. The contents were:
Band One: Introduction / explanation of the TTR-117 and how to use it.
Band Two: Level and Balance tests.
Band Three: Polarity (Phasing) tests.
Band Four: Skating compensation test.
Band One: Examples of audible mistracking.\
Band Two: Introduction to trackability test.
Band Three: Trackability test at six modulation levels using a complex test tone of 200 Hz, 2100 Hz, and 17,000 Hz.
Band Four: Tone arm resonance test using successive sub-audible tones of 5 Hz through 14 Hz.
Sorry, the TTR-117 is no longer available.
