Item
NORM-tape, HIGH-speed mode
Input a 5 kHz signal (-20 dB level down)to the REC EQ IN
pin and then measure the relative deviation from NORM-
NS, 315 Hz mode.
NORM-tape, HIGH-speed mode
Input a 15 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
NORM-tape, HIGH-speed mode
Input a 20 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
CrO
Input a 5 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
CrO
Input a 15 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
CrO
Input a 20 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
METAL-tape, HIGH-speed mode
Input a 5 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
METAL-tape, HIGH-speed mode
Input a 15 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
METAL-tape, HIGH-speed mode
Input a 20 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
NORM-tape, NORM-speed mode
Alternately input a 1 kHz signal (+12 dB level up) and
measure the channel crosstalk. (Use a 1 kHz BPF.)
NORM-tape, NORM-speed mode, RL = 2.7 kΩ
Input a 1 kHz signal and set the output level so that THD
(total harmonic distortion) is 1%. (Measure the distortion
of a +9 dB level-up signal.)
NORM-tape, NORM-speed mode, RL = 2.7 kΩ
Input a 1 kHz, 0 dB (reference input level) signal and
measure the distortion. (Measure the distortion as THD + N.)
NORM-tape, NORM-speed mode, Rg = 5.1 kΩ
With no signal, measure the noise using the "A"-WGT
filter. (The measured value is indicated as the relative
value compared to the reference level.)
NORM-tape, NORM-speed mode
With no signal, measure the DC offset voltage of the REC
OUT pin.
