10. AD 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. Dur-
ing audio signal processing, the condition before execu-
tion is maintained.
When K0/K1 menu is selected, keys become non-oper-
able 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.
* The figures in the diagram are given as reference only.

PS1/PS2 (Power supply voltage protection detection)

Power supply voltage protection value (Normal value: PS1:
17 to 66, PS2: 36 to 53)
PS1: Detects +5S and +5.3X (U, C models).
PS2: Detects ±12V, ±5V, +5D, +3.3D and +5i.
* If PS is out of the normal value range, the protection
function works to turn off the power.
(Reference voltage: 5 V=100 %)

DC/TH (protection detection/temperature detection)

DC: DC detect protection value (Normal value: 5 to 36)
* If DC is out of the normal value range, the protection
function works to turn off the power.
(Reference voltage: 5 V=100 %)
TH: Detects the temperature of the heat sink.
Temperature detected value
(Normal value: 9 to 177) U, C, T, K, A, G, E, J models
(Normal value: 9 to 167) R, L models
(Reference voltage: 5 V=255)
