NORM-NORM mode
REC-EQ mute characteristics 1
(REC-MUTE = 0.5V)
Conditions
Min. Typ. Max. Unit
NORM-tape, NORM-speed mode, Rg = 5.1kΩ
With no signal, measure the noise using the "A"-
WGT filter. (The measured value is indicated as 57 65 — dB
the relative value compared to the reference
level.)
NORM-tape, NORM-speed mode
With no signal, measure the DC offset voltage of –500 0.0
the REC OUT pin.
500 mV
NORM-tape, NORM-speed mode, REC-MUTE = 0.5V
Input a 1kHz signal (+12dB level up) and
measure the attenuation when REC MUTE is on. —
(Use a 1kHz BPF.)
–91 –80 dB
NORM-NORM mode
REC-EQ mute characteristics 2
(REC-MUTE = 2.5V)
NORM-tape, NORM-speed mode, REC-MUTE = 2.5V
Input a 1kHz, 0.0dB (reference level) signal and
measure the attenuation characteristics curve of
the soft mute function. (when REC-MUTE = 2.5V)

NORM-tape, NORM-speed mode, REC-CAL = 5.0V
NORM-NORM mode
Input a 315Hz signal (–20dB level down) and
REC-EQ REC-CAL characteristics 1 measure the amount of change compared to
4.1
(REC-CAL = 5.0V)
when the REC-CAL function is at the standard
setting.
NORM-NORM mode
REC-EQ REC-CAL characteristics 2
(REC-CAL = 0.0V)
NORM-tape, NORM-speed mode, REC-CAL = 0.0V
Input a 315Hz signal (–20dB level down) and
measure the amount of change compared to
when the REC-CAL function is at the standard
setting.
–8.9
NORM-tape, NORM-speed mode, Gp-CAL = 5.0V
NORM-NORM mode
Input a 8kHz signal (–20dB level down) and
REC-EQ Gp-CAL characteristics 1 measure the amount of change compared to
3.9
(GP-CAL = 5.0V)
when the Gp-CAL function is at the standard
setting.
NORM-NORM mode
REC-EQ Gp-CAL characteristics 2
(GP-CAL = 0.0V)
NORM-tape, NORM-speed mode, Gp-CAL = 0.0V
Input a 8kHz signal (–20dB level down) and
measure the amount of change compared to
when the Gp-CAL function is at the standard
setting.
