2. Safety-check out (North American model only)
Before returning the product to the customer, make leakage current or
resistance measurements to determine that exposed parts are acceptably
insulated from the supply circuit.
Parts marked with the symbol are critical with regard to the risk of fire and
electric shock.Replace only parts recommended by the manufacturer.

ALIGNMENT PROCEDURE (T975)
A. THERMAL SENSE ADJUSTMENT
This adjustment should be always done when the T975 is in a cool condition. (That means the
temperature inside the unit should be almost same as the ambient temperature.)
Connector P208B that connects the transformer and power board should be removed to
avoid the Idling current heating up the unit excessively) At ambient temperature of 25 C
degrees and when the unit is just turned on (still in cool condition), adjust the pot
RV103 (as marked as “Thermal Sense ADJ”in below drawing) for a voltage between the
THERMAL TEST POINT and AGND to be 750mV+/-10mV. If the ambient temperature is
different, the voltage setting should be changed by 20mV per degree C difference. So at
20C degrees, the voltage should be 850mV+/-10mV; and at 30C degrees, the voltage
should be 650mV+/-10mV, etc.
B. DC OFFSET VOLTAGE
The DC OFFSET between OFFSET Test Point and AGND must be within 0+/-3mV. If it’s
found to be out of this range, change the TL084BCD to one selected for low offset voltage
to meet the requirement.
C. IDLING CURRENT
The idling current in the output stage of the poweramp should be set to 40mA+/-10mA
per pnp-npn transistor pair (This means the mid point voltage is 17.6mV with down limit of
13.2mV and up limit of 22mV). The alignment procedure is: At first, adjust RV102 (Marked
as “Idling Current ADJ”in the drawing below) for a voltage of 17.6mV +/- 1mV between
Testpoint1and2.Thenpre
heat the unit for 5 minutes, let idling current settled and then
readjust to 17.6mV +/- 1mV.
Pls note:
1. The idling current must be adjusted when all modules are assembled into the unit.
2. Though the idling current is set as 17.6mV +/-1mV during the adjustment, due to the
influence of varied ambient temperature and mains voltage etc., the idling current will drift
after some time. During the normal checking of idling current in the service field, it’s
acceptable as long as the voltage is in the range of 13.2mV—22.0mV.
D. ISC SENSITIVITY
The ISC sensing voltage range is 0mV+/-50mV. But, for the alignment process during
production, we tighten the limit to 0mV+/-10mV. That is to adjust Pot RV104 (as marked as
“ISC SENSE ADJ”in the below drawing) to get a voltage between the “ISC SENSE TEST
POINT”and AGND to be 0mV+/-10mV.
(Please note the ISC should be adjusted when all modules are plugged in. It’s not possible to get
0mV +/-10mV if any of the modules are removed.)
E. Fan Cut Off Point Adjustment
Check the Fan sense voltage first. Turn Pot RV201 (on the power supply board) to the end clockwise
and confirm TP1of J201 is negative voltage. Run the unit to heat it up and to start turning the fan.
-5-
For example; all 7 channels at 50W/4 ohms for 10 minutes or 5 minutes or even less (as
long as the fan can starts turning). Turn off the signal but still keep the unit operating for 1
minute. Then run all 7 channels at 1kHz, 0.25W at 4 ohms load, monitor the voltage at
TP1 J201. Adjust RV201 to get the voltage from negative to positive to ensure
that the Fans are turned off. Then run all 7 channels at 1kHz, 0.5W at 4 ohms
load, monitor if the voltage at TP1 of J201 is negative, if not, adjust Pot RV201 just
to the point that TP1 changes from positive to negative (to get the fans just start turning).
Finally, turn off the signal and monitor if fans stop turning within about 30s Maximum.

** For countries with higher than expected mains voltage, one may change C247 and C248 from
CD294 15000uF 80V 105°C four pins 35x100 (P/N 06-15381-01) to CD294 10000uF 100V 105°C ±20%
four pins 35x100 (P/N 06-10312-02),and change C253 and C254 from CD294 22000uF 80V 105°C four
pins 35x100 (P/N 06-22381-00) to CD294 10000uF 100V 105°C ±20% four pins 35x100 (P/N 06-10312-02).
*** One may use 06-10212-01 1000uF 100V 105°C for C224 and C225 instead of 06-10281-01 @ 80V.
