1.Overload Protection All this series amplifiers has output current protection. Output current will be limited when exceeds the allowed maximum value. When a channel of a amplifier output current exceed the allowed maximum value (For example,Short circuit). In this case, the amplifier itself will be disabled (mute) for 1000ms. Amplifier will restart after the short circuit back to normal.
2.Input Voltage Protection When input voltage is higher than the upper limit or lower than the lowest limit, PSU will enter protect mode and cut off the power supply. 3.Temperature Protection Complete temperature protection sampling. Monitor both PSU and amplifier simultaneously. Output power will limit when the temperature of the heatsink higher than limit value. Output will cut off when temperature higher than the protect value. Amplifier will restart when temperature return to normal.
