DC/TH
DC: Power amplifier DC (DC voltage) output is detected.
Normal value: 32 to 74
(Reference voltage: 3.3 V=255)
TH: Temperature on the heatsink is detected.
Normal value: 0 to 124
(Reference voltage: 3.3 V=255)
* If DC or TH becomes out of the normal value range, the protection function works to turn off the power.

IMP/PL
IMP: 8 or 6 ohms impedance setup detection
IMP 8: 8 ohms setting
IMP 6: 6 ohms setting
PL: PLDET (Power amplifier output voltage detection)
The power amplifier output voltage is detected and the power amplifier input voltage is controlled according to the
detected output voltage.
