In the following circumstances protect the LED is on
.In the self-test procedure after the power is on, the LED is lit continuously on for about 2S.
In this process there is no output.
.the excessive signal causes clipping, the led flashes, the breif flashes makes no influence
to the distortion. The excessive and continuous clipping may destroy the speakers. So pls
turn down the volume when the leds shin frequently.
.If the output cable is short cut, the indicator will keep on. But if the volume is turned off, the
indicator may be off. Pls check the load and output cables.
.If the protect be shut down because of the over high temperature, pls turn the amp off, check
whether the ventilation or the wind grid is good.
.When the power is power during working or the power supply voltage is too high, the indicator
will keep on.
.If the amplifier fault is not in accordance to the above situations, while the Protect indicator
keeps on, pls turn to the professional engineer.
When the "STBY IN" and "GND" or "STBY THRU" and "GND" are short
cut, the main power amplifier will be forced off. The machine will turn to
standby mode, with consumption less than 60W.
They are electrically connected in parallel; you can input from one
socket and output from another socket and connect to the remote
standby control interface of the next amp.
Note:
When cascade, the GND terminal of the "Remote Standby control
interface" should connect to the GND terminal of the next one ac
-cordingly; otherwise it will cause the machine to turn to the standby
mode and it cannot work properly.
STATE OUT
When the normal state circuit is operating, this port output high lever(+5 V).
The use of the terminal, according to the case-channel power ON / OFF
state and the protection of the state, to control external connected device
(monitor display panel) indicator lights up and the operation of the power
of the lamp is turned on.
The circuit is designed to monitor the voltage between terminals 5 and 6
feet 5V; please currents when used in a closed environment below 12mA.
