Procedure
1. Adjust the INPUT level control so that the
meter reads - 5.2dBv (549mV).
2. Switch the DOLBY NR switch ON.
3. Record the 333H2, - 10dBv signal on the
STD-608A test tape. Then adjust VR102
(L ch) and VR202 (R ch) so that the meter
reads - 5.2dBv (549mV) when the recorded
signal is played back.
4. Switch the tape selector to the CrO2 position
and repeat step 3 using the STD-603 test
tape. The playback output level should lie
within - 5.2dBvt1.5dB.
5. Then switch to the METAL position and repeat
using the STD-604 test tape. The playback out-
put level should again lie within the - 5.2dBv
t1.5dBv range.
