◆ CPL- Current Peak Limiter: Make sure to ensure the power amplifier output current does not exceed safe parameters.
◆ Temperature protection: Make sure the amplifier will not overheat and damage.
◆ VHF- VHF: when detecting a non-dynamic continuous signal, the output of the power amplifier is reduced. DC protection: ensure that hazardous DC signal does not appear at the output of the power amplifier. If this happens, the internal fuse will be disconnected, an error indication is displayed.
◆ low impedance (short circuit) protection: When the input signal dysfunction or output short circuit, the error indicator will light up and turn off the output.
◆ High Impedance Protection: When the output signal is large and measuring less than current consumption, high impedance will be issued a warning. This situation may occur in the absence of connecting speakers or amplifier malfunction.
◆ Low start-up current: Ensure open simultaneously when several power amplifiers, power circuit breakers are not tripped
