PR4 1000-2

Class D Power Amplifier

High-Power Class D Amp

The PRx-1000-2 series amplifier is a class D high-power amplifier with up to 8 inputs and outputs. It is mainly intended for fixed sound installations and suitable even in surroundings where low operating noise is relevant. Due to its cooling concept with large heatsinks and microprocessor-controlled ultra-low noise fans, the amplifier remains quiet even under full load conditions.

In combination with our 8-channel Dante Breakout Box DBO1, you get a super-silent replay out of a Dante network.
