DAP-Audio Qi-4400 4x 400 W amplifier

The DAP Qi-4400 is a 4x 400 watt amplifier suitable for the DAP-Xi speaker range. It can also be applied for mobile use due to its rugged steel housing. Each of its four channels has its own gain control and protect, limit and signal indicator LEDs.

The Qi-4400 has 4 routable XLR inputs and speakON outputs. They can be set in either bridge and stereo mode. Equipped with SMPS and Class D amplification, it is a lightweight and energy efficient solution delivering a high quality sound signal.

This device is save to use thanks to its advanced protection circuit. It is protected from overload, overheat and clipping due to various built-in protection mechanisms, such as a softstart and clip limiter. Furthermore, the Qi-series is made with high-quality low-deviation components to ensure a long lifespan and a perfect sound quality.Technical data:
