Today's most advanced digital amplifier technologies with installer-friendly features to create a robust power plant for demanding audio applications. Unlike analog amplifiers from the competition, our digital amplifiers are much more energy efficient and run up to 80% cooler than traditional analog amplifiers. Three convenient turn-on modes make it easy to integrate with simple volume controls or sophisticated control systems. Audio-sense is perfect for Sonos or Apple Airplay multi-room audio – when the last source shuts down, the amplifier will gracefully go into a power-saving standby mode.
