5. INDEICATORS ON FRONT PANEL
PWR/ERR indicator for each separated channels, more indicates as below:
PWR/ERR lights up red when the amplifier is powered on during self-examine process.
This process will not have any output after 5S self-examination, PWR/ERR lights turn green.
PWR/ERR lights flashing when the amplifier is short circuit or at too low impedance,
however it can be a green light by turn off volume .Please check the loading impedance and
output connection.
PWR/ERR lights red when device temperature is over the limit and output is temporarily cut off.
Please turn off the amplifier, improve the cooling condition and clean the ventilation.
PWR/ERR lights continuous red when power supply voltage too high or too low, please use
the correct one. In this situation, the amplifier can get back to normal work when power
disconnects 3 minutes or more.
PWR/ERR lights red when defection appears, if you are not sure the problems,
please consult technicians.

B. For above menu, use CHA and CHB knob to adjust the channel volume, max volume is 0dB.
SINGNAL output indicator for each separated channel.
SINGNAL signal indicator is equivalent to outputs paralleled on the circuit. When the Gain is
turned to minimum and whether there is input signal, the signal indicator will not light up.
CLIP output clipping indicator for each separated channel.
When input signal is too big, the CLIP indicator lights up. Too strong and continuous clip may
cause damage to the speaker and sound. Please reduce gain or signal input when the clip is
too frequent.
BRIDGE indicator, it's switched to bridge mode, means two channels are bridged.
