ADVANCED PROTECTION FUNCTIONS

• Overload protection:
  This amplifier series has output current protection function. If the current output by the channel exceeds the peak current, the current is limited to the limit value with the help of a protector inside the device. If the amplifier’s output current exceeds the peak current, the power amplifier will be muted within 1 second and the device will automatically restart once the short circuit condition ceases.

• Over voltage and undervoltage protection:
  When the amplifier operating voltage exceeds the maximum allowable voltage or is lower than the minimum voltage, the amplifier power supply will activate the protection mode and cut off the power supply.

• Power control:
  This amplifier series supports the power output control function. You can adjust the gain value on the amplifier panel to help the connected speakers operate safely and stabe.

• Overheating protection:
  Both the internal temperature and the cooler temperature can be monitored simultaneously, so if the internal temperature of the amplifier exceeds the limit, the output is cut off and the amplifier restarts after the temperature drops to a safe range.

ADVANCED PROTECTION FUNCTIONS

• STEREO MODE: Stereo mode is the most common setup in which each channel of the amplifier operates independently. Each input signal is output to each channel

• PARALLEL MODE: Parallel mode is a mode that can output two channels with one input signal. It can be used only by connecting to the input terminal of Ch1.

• BRIDGE MODE: Bridge Mode is a mode that produces higher output by using the channels of two amplifiers as one. Connect to the input terminal of Ch1.
