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 by 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 becomes out of the normal value range, the protection function works to turn off the power.
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 becomes 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.
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 becomes out of the normal value range, the protection function works to turn off the power.
