The ALC1000 comes chassis mounted, acting as a heat sink, making it easy to integrate into a wide range of products from active subwoofers and speakers through to home audio products.

The module is based on a phase shift modulated topology with advanced protection circuitry and gives very low distortion.

A powerful switch mode power supply gives 1000W continuous power with 2000W peak output power for short periods of time to cover the reality of music.

The power supply is inherently designed for ultra low noise making it well suited to the demands of audio and consumer electronic products. It also delivers +/-supplies to an external PCB, for example a cross over board or pre amplifier board in a dual mono integrated amplifier.

The built in over current protection has two modes. During transients into the current limit threshold it allows constant output current but if this condition persists it goes into burst mode. This guarantees that the amplifier does not create audio holes during heavy listening but still effectively protects it during short circuiting.

The thermal protection is by a sensor connected to the very tab of one of the output devices giving a very fast detection and shut down should over-load occur.
