NOTE:
1 . The proper bias adjustment is most important to correct performance of the amplifier.
assu re
' Bias adjustment is necessary if any of the transistors are replaced in the power amplifier
circuitry or the amplifier exhibits overheating of the output transistors under normal
operating conditions.
2. This Receiver has built-in overload thermal protections, one is installed within power trans-
fornier and the others are installed on heat sinks of power transistors.
ln case of the thermal protector of power transformer, when the temperature of thermal
protector reach to 135t5'C, the thermal protector will be automatically cut out, and as
soon as the temperature goes down to 110t10'C, the thermal protector turns back on
automatically.
The protectors of heat sinks have the same effect as above except for working temperature.
When their temperature rises up to 115t5"C, these protectors will be automatically cut
out, and as soon as the temperature falls down to 40t19'9, these protectors turn back on
automatically.

Ci. CHANGING POWER LINE VOLTAGES
The NAD300 has a multi-voltage Power Transformer of 12OV,22OV and 240V.
1. Remove the chassis out of cabinet and open the bottom cover of chassis.
2. Change the soldering of primary transformer wire as follows (with a setting of 22OV as indi-
cated in figure).
A, To change from22OY to24OV.
Remove the white wire from pin-2 of terminal strip and connect the white wire to pin-1
(already connected orange wire).
B. To change trom 22OV to 120V.
Remove the orange wire from pin-1 and the white wire from pin-3 of terminal strip, then
connect the orange wire to pin-4 of terminal strip and the white wire to lug of fuseholder
(alredy connected gray wire).
Also remove the white wire to pin-2 of terminal strip and connect the white wire to pin-3
of terminal strip.
,,WARN ING" lf the power transformer connections are not set for the correct local voltage
the set will be damaged in case it is switched on.
Please RE-CHECK the connections before power goes on.
