4-channel PA power amplifier with 5 kW power. The QDA-4400 PA power amplifier offers maximum power with low weight and low height. This is made possible by the use of a Class D architecture. Together with a modern switching power supply, rated power of up to 5 kW is possible at a weight of less than 10 kg. This makes the amplifier particularly attractive for mobile applications and allows it to be used very flexibly in stereo operation, parallel operation, or bridge operation. The amplifier and loudspeakers are optimally protected by a comprehensive protection circuit package.
