4-channel PA amplifier with 5kW of power
The QDA-4400 PA amplifier offers ultra-high output power paired with a low weight and small overall height. The amplifier uses a Class D output circuitry. Featuring a modern switch-mode power supply, the amplifier provides up to 5 kW peak power and weighs less than 10 kg. This makes this model particularly attractive for mobile applications. The amplifier can be used flexibly in stereo operation, parallel operation or in bridge operation. Extensive protective circuits will protect the amplifier and the speakers connected.
