P1. SYSTEM MONITOR
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
“
P1-6. KEY
”
sub-menu is selected, keys become inoperable due to detection of the values of all keys.
However, it is possible to advance to the next menu by pressing the
“
SCENE RADIO
”
(forward) key or
“
SCENE NET
”
(reverse) key on the remote control.
* Numeric values in the figure are given as reference only.
P1-1. DC
Power amplifier DC (DC voltage) output is detected.
The voltage at
5
pin (DC_PRT) of IC78 is displayed.
Normal value: 32 to 74
(Reference voltage: 3.3 V=2
55
)
* If DC becomes out of the normal value range, the protection function works to turn off the power.
P1-2. PS
Power supply voltage (PS) protection detection.
The voltage at 1 pin (PS1_PRT)/2 pin (PS2_PRT)/1
5
pin (PS3_PRT) of IC76 are displayed.
Voltage detects
PS1:
AC12, AC-BL
PS2:

)
* If PS1, PS2 or PS3 becomes out of the normal value range, the protection function works to turn off the pow-
er.
