dBv
equalizer amplifier Recording reference output level (This output level is the tape reference 0 dB which
NORM-NORM mode
generate magnetic flux of 250 nWb/m)
All of the recording equalizer amplifier blocks use this
level as their reference level.

(For measurement, input a 315 Hz, -23 dBv signal to the
REC EQ IN pins and then measure the output level.)
