8-1. TEST
ALL
The test noise is output from all channels.
8. MANUAL
TEST
The built-in noise generator of DSP outputs the test noise through the channels specified by using the sub-menu.
8 . T E S T A L L
9. A/D DATA CHECK
This menu is used to display the A/D conversion value of the microprocessor which detects panel keys and protection
functions by using the sub-menu.
When K1/K2 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 main menu by turning the “VOLUME” knob of this unit.

Numeric values in the figure are given as reference only.
9-1. PS/DC
PS:
Power supply voltage protection detection
Detected:
AC2, ±12A, S9, +7D, +5A, +5I, -VP
Detection port:
93 pin (PS_PRT)
Normal value:
101 to 155
(Reference voltage: 3.3 V=255)
DC:
Power amplifier DC (DC voltage) output is detected.
Detection port:
87 pin (DC_PRT)
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.
P S : 1 2 6 D C : 0 5 8
9-2. TH1/TH2
Temperature of the heatsink is detected.
Detection port:
89 pin (THM1_PRT)
90 pin (THM2_PRT) (U, C models)
Normal value:
87 to 255
(Reference voltage: 3.3 V=255)
*
If TH1 or TH2 becomes out of the normal value range, the protection function works to turn off the power.
