4-4. THM
Temperature detection
Temperature of the heatsink is detected by IC501 of the MAIN P.C.B..
Normal value:
41 to 317
(Reference voltage: 5.0 V = 1023)
4-5. VOLUME
VOLUME knob position detection
The voltage at 97 pin (I-VOL) of microprocessor IC101 is displayed.
Normal value:
0 (MIN) to 1010 or more (MAX)
(Reference voltage: 5.0 V = 1023)
4-6. BASS
BASS knob position detection
The voltage at 94 pin (I-BAS) of microprocessor IC101 is displayed.
Normal value:
0 (-) to 1010 or more (+)
(Reference voltage: 5.0 V = 1023)
4-7. TBL
TREBLE knob position detection
The voltage at 95 pin (I-TRE) of microprocessor IC101 is displayed.
Normal value:
0 (-) to 1010 or more (+)
(Reference voltage: 5.0 V = 1023)
4-8. BAL
BALANCE knob position detection
The voltage at 93 pin (I-LRBAL) of microprocessor IC101 is displayed.
Normal value:
0 (L) to 1010 or more (R)
(Reference voltage: 5.0 V = 1023)
4-9. CNT
Center position detection of BASS, TREBLE and BALANCE knobs
Normal value:
470 to 552
(Reference voltage: 5.0 V = 1023)
*
If THM becomes out of the normal value range, the protection function works to turn off the power.
