9. A/D DATA CHECK
This menu is used to display the A/D conversion value of the microprocessor which detects panel keys of this unit and

9-1. PS/DC
PS: Power supply voltage protection detection
Voltage detects: AC2, ±12A, S9, +7D, +5A, +5I, -VP
Normal value: 101 to 155
(Reference voltage: 3.3 V=255)
DC: Power amplifier DC (DC voltage) output is detected.
Normal value: 27 to 88
(Reference voltage: 3.3 V=255)
*
If PS or DC becomes out of the normal value range, the protection function works to turn off the power.

9-2. TH1/TH2
Temperature of the heatsink is detected.
Normal value: 87 to 255
(Reference voltage: 3.3 V=255)
