4) Do the same adjustment for UNIT B with VR202
and VR203.

L.
Notel:
Distortion in the EFFECT OUTPUT increases if adjust
ment 2) and 3) are not correct.
Note 2:
If you have a Distortion Meter, you can confirm
distortion ratio as shown below by inputting sine
wave of 400Hz, -10dBm to SDD-1200 UNIT A.
1) DIRECT VR 0, EFFECT VR 10: Distortion ratio
= less than 0.5%.
2) DIRECT VR 10, EFFECT VR 0: Distortion ratio
= less than 0.05%
7) Feedback Check and Adjustment.
Set as above, then;
1) Input sine waveform of 400Hz, -24dBm form
a Standard Signal Generator (SG) to
SDD-1200.
2) Confirm if it does not feedback when FEED
BACK VR is set to ±8 and feedbacks at ± 10.
3) If necessary adjust VR101 for UNIT A and
VR201 for UNIT B.
Note: ;
If each value of plus and minus is different, you can i
use the one that is easier to feedback. [

4) Set the input signal to "0" and confirm if it
does not feedback when FEEDBACK VR is set
to ±10.
