Before following adjustment, head cleaning is needed.
A. Playback Level Adjustment
_ TAPE SELECT switches: NORMAL
DOLBY NR Switch: OFF
Test Tape: MTT-150
1. Playback the test tape with the TAPE A deck.
2. Adjust the SVR701 (Left Channel) and SVR801
(Right Channel) to obtain 0.56 V output on VTVM.
3. Playback the test tape with the TAPE B deck.
4. Adjust the SVR702 (Left Channel) and SVR802
(Right Channel) to obtain 0.56V output on VTVM.
NOTE: When 0.56V output is obtained on VTVM,
confirm that the +3VU LED is illuminating.
Record Level Adjustment
TAPE SELECT Switches: CrO2
DOLBY NR Switch: OFF
Test Tape: AC-512
1. Insert the test tape into the TAPE B deck.
2. Press the PAUSE button and then press the RE-
CORD button.
3. Apply 1kHz, 19dB input to the LINE IN jacks of
the set.
LOCATION
4. Adjust the record monitor output to 0.36V with
INPUT LEVEL control.
5. Release the PAUSE button and record the input
signal.
6. Playback the recorded section and confirm that the
output is 0.36 V.
7. If not, adjust the SVR703 (Left Channel) and
SVR803 (Right Channel) and then repeat the re-
cord/Playback until 0.36V output on playback is
obtained.
Record/Playback Frequency Response Adjustment
TAPE SELECT Switches: NORMAL
DOLBY NR Switch: OFF
Test Tape: AC-223
1. Record the 1kHz and 10kHz 39dB input signal
continuously.
2. Playback the recorded section and compare the
output level of 10kHz with 1kHz. They should be
same output levels.
3. If there is difference of output between 1kHz and
10kHz, adjust the SVR704 (Left Channel) and
SVR804 (Right Channel}, and then repeat the
record/playback until same output level is obtained.
