4-Channel PA Amplifier with Switching Power Supply

The 4-channel power amplifiers of the QCA series offer maximum performance with low weight and compact height. This is made possible by the use of a patented second-generation Class-I architecture, which combines the efficiency and sound quality of the well-known Class A and Class D architectures. Together with a modern switching power supply, nominal outputs of up to 10 kW are achievable at less than 14 kg weight. This makes the amplifiers particularly attractive for mobile applications and allows for flexible use in stereo, parallel, or mono bridge operation. A comprehensive protection circuit package optimally protects both the amplifiers and the speakers.
