. PLAYBACK LEVEL ADJUSTMENT
(See Fig. 15)
1) Connect a High Sensitivity V.T.V.M. to the Line
Output.
2) Set Tape Speed Selector to 7-1/2 ips.
3) Set Monitor Switch to TAPE position and Line
Output Level Control.VRS5a, 5b to maximum.
4) Playback a 250 Hz, 7-1/2 ips pre-recorded tape.
5) With P.B. Amp. P.C. Board (ND-5037) semi-
fixed resistor VR1 (SO KB), set Line Output level
of both channels to 4 dB +1 dB at- FWD and
4 dB +1.5.dB at REV.
. VU METER SENSITIVITY ADJUSTMENT
(See Fig. 15)
After Playback Adjustment is completed ‘and. an
indication of +4 dB is attained; adjust P.B. Amp.
P.C. Board (ND-5037) semi-fixed resistor WR2 (5
kB) to obtain a. VU meter indication of “O” VU
on both channels.
