PI: 12 DE:255
PI/DE
PI:
PRI (Current protection detection)
The current of the power amplifier is detected.
Normal value:
0 to 100 (Reference voltage: 3.3 V=255)
DE: PDET (Sub-trans power detection)
Normal value:
209 to 255 (Reference voltage: 3.3 V=255)
* If PRI and PDET are out of the normal value range, the protection function works to turn off the power.

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
protection functions in using the sub-menu.
When K0/K1 menu is selected, keys become non-operable due to detection of the values of all keys. However, it is
possible to advance to the next sub-menu by turning the VOLUME of this unit. When using this function, note that
turning the VOLUME more than 1 click would cause the volume value to change.
Signal processing is maintained in the status before execution.
* The figures in the diagram are given as reference only.
PD/PV
PD:
PRD (Power amplifier DC protection detection)
The output of power amplifier DC (DC voltage) is detected.
Normal value:
35 to 81 (Reference voltage: 3.3 V=255)
PV: PRV (Voltage protection detection)
Voltage detects: ACL, AC2, 10V, S9, +12,
-12, +5V and VP
Normal value: 84 to 153 (Reference voltage: 3.3 V=255)
* If PRD and PRV are out of the normal value range, the protection function works to turn off the power.
PD: 57 PV:128
TH/PL
TH:
THM (Thermo protection detection)
The temperature of the heat sink is detected.
Normal value:
0 to 124 (Reference voltage: 3.3 V=255)
* If THM is out of the normal value range, the protection function works to turn off the power.
PL: PLDET (Power limiter detection)
The output voltage of power amplifier is detected.
