Description

Characteristics :

Digital power amplifier Class D 250W
High PWM amplifier efficiency
Control of all functions via MCU
LCD display
Dual SMPS power supply circuit (AC/DC, DC/DC)
Automatic AC to DC power supply switching in case of emergency.
Low power consumption in stand-by mode
Protection in case of overheating, overload, short circuit, low voltage, overvoltage.
Modulation circuit to increase the reliability of the amplifier
Natural cooling function
2 inputs (PGM, PRI) the PRI signal is one input on the amplifier, the PGM signal is switched off automatically.
When there is no signal input, the output circuit is not activated to reduce consumption.
Automatic amplifier check, fault check, function check
Built-in output transformer to increase the reliability of the amplifier and loudspeaker.
