±6.5 ±7.0 ±8.0 V
Recording equalizer amplifier reference output level
(315Hz)
(This output level is the tape reference 0dB which
generates magnetic flux of 250nWb/m.)

Recording reference input level
Input level when the reference output level is 315Hz,
–3.0dBv
(For measurement, input a 315Hz, –18.0dBv signal to the
–19.8
–18.3
–16.8
dBv
REC IN pins and then measure the output level.)
Signal handling
(1kHz, THD = 1%, RL = 2.7kΩ)
Input a 1kHz signal and set the output so that THD (total
harmonic distortion) is 1%. RL = 2.7kΩ (Measure the
distortion of a +11dB level-up signal.)

Total harmonic distortion
(1kHz, 0.0dB, RL = 2.7kΩ)
S/N ratio
("A"-WGT filter)
Output DC offset voltage
(REC OUT pin)
Input a 1kHz, 0.0dB (reference input level) signal and
measure the distortion. RL = 2.7kΩ
(Measure the distortion as THD + N.)
With no signal, measure the noise using the "A"-WGT
filter. Rg = 5.1kΩ (The measured value is indicated
as the relative value compared to the reference level.)
With no signal, measure the DC offset voltage of the
REC OUT pin.

Mute characteristics 1
(REC-MUTE = 0.5V)
REC-MUTE = 0.5V (Use a 1kHz BPF.)
Input a 1kHz signal (+12dB level up) and measure the
attenuation when REC MUTE is on.

(REC-CAL = 0.0V)
REC-MUTE = 2.5V
Input a 1kHz, 0.0dB (reference level) signal and measure –6.0 –4.5 –3.0 dB
the attenuation characteristics of the soft mute function.
REC-CAL = 5.0V
Input a 315Hz signal (–20dB level down) and measure
the amount of change compared to when the REC-CAL

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.
