Recording equalizer amplifier reference output level (315 Hz)
(This output level is the tape reference 0 dB which
generate magnetic flux of 250 nWb/m)
All of the recording equalizer amplifier blocks use this
level as their reference level.
Input level when the reference output level is 315 Hz,
-4 dBv
(For measurement, input a 315 Hz, -23 dBv signal to the
REC EQ IN pins and then measure the output level.)
NORM-tape, NORM-speed mode
Input a 3 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
Input an 8 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
Input a 12 kHz signal (-20 dB level down) from the
reference to the REC EQ IN pin and then measure the
relative deviation from NORM-NS, 315 Hz mode.
CrO
Input a 3 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 an 8 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 12 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, NORM-speed mode
Input a 3 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, NORM-speed mode
Input an 8 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, NORM-speed mode
Input a 12 kHz signal (-20 dB level down) to the REC EQ
IN pin and then measure the relative deviation from
NORM-NS, 315 Hz mode.
