Stereo Audio Analyser (1981)
The Nakamichi T-100 Audio Analyzer is a powerful diagnostic instrument which enables you to get the optimum performance from your audio system.
Originally conceived as a tool for the serious recordist, the Analyzer also provides valuable information about preamplifiers, amplifiers, turntables, phonograph cartridges, loudspeakers, and microphones.
The T-100 incorporates the functions of an oscillator, a vacuum tube volt meter, a distortion meter, and a wow & flutter meter in a compact, portable form.
The oscillator provides 21 different frequencies and pink noise for accurate frequency measurements from 20Hz to 20kHz. The pink noise generator is particularly useful for subjective testing of tape decks, loudspeakers, and microphones.
The 400Hz oscillator can be used with the built-in distortion analyzer to measure the harmonic distortion of tape decks and amplifiers.
The 3kHz oscillator allows you to test a tape deck's record/play wow & flutter with a choice of weighted or unweighted readings.
With a 3kHz test tape, you can measure playback-only tape speed deviation and wow & flutter. With a 3kHz test record, you can measure turntable wow & flutter.
The T-100 also provides A-weighted noise readings of inputs down to 10uV.
Finally, the Analyzer provides extremely accurate peak or average level indication. You can use the Analyzer to supplement the VU meters of your tape deck and avoid tape saturation when you record.
By connecting the Analyzer in parallel with your speakers, you can avoid amplifier/speaker overload when you play back.
