Item
NORM-tape, NORM-speed mode, REC-MUTE ON
Input a 1 kHz signal (+12 dB level up) and measure the
attenuation when REC MUTE is on. (Use a 1 kHz BPF.)
NORM-tape, NORM-speed mode, REC-CAL = 5.0 V
Input a 1 kHz signal (-20 dB level down) and measure the
amount of change compared to when the REC-CAL
function is at the standard setting.
NORM-tape, NORM-speed mode, REC-CAL = 0.0 V
Input a 1 kHz signal (-20 dB level down) and measure the
amount of change compared to when the REC-CAL
function is at the standard setting.
NORM-tape, NORM-speed mode, GH-CAL = 5.0 V
Input an 8 kHz signal (-20 dB level down) and measure
the amount of change compared to when the GH-CAL
function is at the standard setting.
NORM-tape, NORM-speed mode, GH-CAL = 0.0 V
Input an 8 kHz signal (-20 dB level down) and measure
the amount of change compared to when the GH-CAL
function is at the standard setting.
NORM-tape, NORM-speed mode, fQ-CAL = 5.0 V
Input an 8 kHz signal (-20 dB level down) and measure
the amount of change compared to when the fQ-CAL
function is at the standard setting.
NORM-tape, NORM-speed mode, fQ-CAL = 5.0 V
Input a 12 kHz signal (-20 dB level down) and measure
the amount of change compared to when the fQ-CAL
function is at the standard setting.
NORM-tape, NORM-speed mode, fQ-CAL = 0.0 V
Input an 8 kHz signal (-20 dB level down) and measure
the amount of change compared to when the fQ-CAL
function is at the standard setting.
NORM-tape, NORM-speed mode, fQ-CAL = 0.0 V
Input a 12 kHz signal (-20 dB level down) and measure
the amount of change compared to when the fQ-CAL
function is at the standard setting.
REC-VOL = 5.0 V, REC-BAL = 2.5 V
Input a 1 kHz, -10 dBv signal to the LINE IN pin and
measure the full gain of the recording volume amplifier.
REC-VOL = 2.0 V, REC-BAL = 2.5 V
Input a 1 kHz, -10 dBv signal to the LINE IN pin and
measure the attenuation of the recording volume
amplifier.
REC-VOL = 0.0 V, REC-BAL = 2.5 V
Input a 1 kHz, +2 dBv signal and measure the maximum
volume attenuation of the recording volume amplifier.
(Use a 1 kHz BPF.)
REC-VOL = 2.0 V, REC-BAL = 2.5 V, RL = 2.7 kΩ
Input a 1 kHz signal and set the input level so that the THD is
1%. (Measure the distortion when the output is +2 dBv.)
REC-VOL = 2.0 V, REC-BAL = 2.5 V, RL = 2.7 kΩ
Input a 1 kHz, -10 dBv signal (reference input level) and
measure the distortion. (Measure the distortion as THD +
N.)
