“I used the Fozgometer as described in the instructions and using the Analogue Productions The Ultimate Analogue Test LP, I obtained readings that matched what I obtained using the digital oscilloscope…I feel it is a reliable tool to use for setting azimuth.” - Michael Fremer, Analog Planet USA

“Provides an ingenious and not too expensive solution, which is designed to be used in conjunction with The Ultimate Analogue Test Disc…the Fozgometer is very simple to use.” - Chris Martens, HiFi+ UK


Phono cartridge azimuth is a key parameter for getting the best stereo imaging and soundstaging. For optimal stereo performance from a modern phonograph system, the pickup cartridge azimuth must be properly adjusted.  Prior to the Fozgometer, one had to use an oscilloscope, AC voltmeter, or computer program, methods can be expensive and time consuming.

The FOZGOMETER is a small portable battery powered meter that is used in conjunction with a test record to measure channel separation, channel balance, and signal direction quickly and accurately. It incorporates a “Log Ratio Detector”, developed by Jim “Foz” Fosgate for surround processor steering logic circuits, to measure cartridge azimuth. The readings can be made with a wide range of input signals; directly from the tonearm cables, from the output of a phono stage, or from a tape output, without effecting accuracy. Readings are taken without touching the meter, leaving your hands free to adjust the tonearm. The meter reads channel separation in both directions, and channel balance. The LED’s indicate Left, Center, and Right signal (test tone) positions.

For best results, we recommend The Ultimate Analogue Test LP by Analogue Productions:

The Ultimate Analogue Test LP features a comprehensive selection of test tracks and is recommended for use with our Fozgometer. It was produced by Clark Williams of Acoustic Sounds and cut at Sterling Sound on a Neumann VMS-80 cutting lather with a newly rebuilt SX-74 cutterhead.
