P1. AD 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.
Numeric values in the figure are given as reference
only.
P1-1. DC
Power amplifier DC (DC voltage) output is
detected.
Normal value: 30 to 72
(Reference voltage: 3.3 V=255)
If DC becomes out of the normal value range,
the protection function works to turn off the
power.
P1-1
DC: 51
P1-2. PS
Power supply voltage (PS) protection detection.
PS3

PS3
+5.5V
Normal value
PS1:
139 to 186
PS2:
177 to 221
PS3:
112 to 171
(Reference voltage: 3.3 V=255)
If PS1, PS2 or PS3 becomes out of the normal
value range, the protection function works to
turn off the power.
P1-3. TEMPERATURE
TMP1: Temperature of the heatsink is detected.
TMP2: Temperature of the bridge diode is detected.
Normal value
TMP1, 2:
101 to 255 (U, C, T, K, A, B, G, F models)
116 to 255 (R, L, V, P, S models)
(Reference voltage: 3.3 V=255)
If TMP1 or TMP2 becomes out of the normal
value range, the protection function works to
turn off the power.

P1-4. OUTPUT LEVEL
Output level of speaker output is detected.
(Reference voltage: 3.3 V=255)
P1-4
OUTLVL: 255
P1-5. LIMITER CONTROL
Power limiter control is detected.
(Reference voltage: 3.3 V=255)
P1-5
LMTCNT: 255
P1-6. USB
Power supply voltage of USB jack is detected.
Normal value: 166 to 255
(Reference voltage: 3.3 V=255)
If USB becomes out of the normal value range,
the protection function works and
USB Overloaded is displayed.
