N. A/D DATA CHECK
This menu is used to display the A/D conversion value of the microprocessor which detects panel keys of the main
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 the main unit. When using this function, note
that turning the VOLUME more than 1 click would cause the volume value to change.
During signal processing, the condition before execution is maintained.

PD/DI
PD:
PRD (Power amplifier DC protection detection)
The output of power amplifier DC (DC voltage) is detected.
Normal value:
27 to 70 (Reference voltage: 3.3 V=255)
* If PRD is out of the normal value range, the protection function works to turn off the power.
DI: DOCK ID (DOCK ID detection)
(Reference voltage: 3.3 V=255)
N1PD: 45DI: 0
V1/V2
V1:
PRV1 (Voltage protection detection)
Voltage detects: ACL, 10V, VP, +6.3H and +3.3H
Normal value:
68 to 161 (Reference voltage: 3.3 V=255)
V2: PRV1 (Voltage protection detection)
Voltage detects: AC2, +12, -12, +5D, +5I, +5V and -5V
Normal value:
104 to 181 (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.
