Effective value over current protection- fuse protection

Weather the effective power current can temporarily reach the peak depends on the

impedance of the load and the type of signal, because the fuse protection support RMS

several times of the standard power. To prevent turning the amp off in extreme cases, the

amplitude of the input signal should be reduced (due to the SMPS over current protection),

there by reducing the power current consumption.

24V DC power supply

21.6~ 26.5V operating voltage range

Note: Pls don't reverse the positive and negative polarity of the battery

to avoid any damage to the devise. Post 100A current maximum

support, such as more than easily damaged terminals.

100V speaker output

1 channels Class-D amplifier output with source filters to pass invalid

audio signal; available for 100V external speaker. The total power of

the speakers connected to the output terminals can not exceed 80%

of the RMS of the amplifier.

Power LED

When power is turned on, the power LED emits blue light.

Signal LED

SIGNAL is an output signal indicating. When the corresponding outputs

detects a signal is and the output voltage reaches 10V, the signal

LED emits green light. Under normal operating it flashes.

Clip LED

When the output voltage exceeds the rated maximum level, distortion

orange LED lights up. Distortion long bright LED indicates the status of

the peak above the machine work. To avoid serious distortion or cut the

top, so they should be appropriate to reduce the volume.

Protect the LED

When the protection circuit is working, the orange protection LED

indicator on.
