Conditions

METAL-tape, NORM-speed mode

Input a 12kHz signal (–20dB level down) to the

REC IN pins and then measure the relative

deviation from NORM-NS, 315Hz mode.

NORM-tape, HIGH-speed mode

Input a 5kHz signal (–20dB level down) to the

REC IN pins and then measure the relative

deviation from NORM-NS, 315Hz mode.

NORM-tape, HIGH-speed mode

Input a 15kHz signal (–20dB level down) to the

REC IN pins and then measure the relative

deviation from NORM-NS, 315Hz mode.

NORM-tape, HIGH-speed mode

Input a 20kHz signal (–20dB level down) to the

REC IN pins and then measure the relative

deviation from NORM-NS, 315Hz mode.

CrO2-tape, HIGH-speed mode

Input a 5kHz signal (–20dB level down) to the

REC IN pins and then measure the relative

deviation from NORM-NS, 315Hz mode.

CrO2-tape, HIGH-speed mode

Input a 15kHz signal (–20dB level down) to the

REC IN pins and then measure the relative

deviation from NORM-NS, 315Hz mode.

NORM-NORM mode

REC-EQ signal handling

NORM-tape, NORM-speed mode, RL = 2.7kΩ

Input a 1kHz signal and set the output so that

THD (total harmonic distortion) is 1%. (Measure 11.0 12.0 — dB

the distortion of a +11dB level-up signal.)

NORM-NORM mode

NORM-tape, NORM-speed mode, RL = 2.7kΩ

Input a 1kHz, 0.0dB (reference input level)

REC-EQ total harmonic distortion

(1kHz, 0.0dB, RL = 2.7kΩ)

signal and measure the distortion. (Measure the

distortion as THD + N.)
