PR4 1000-2

DSP Controlled Class D Power Amplifier

DSP-Controlled Amplifier

The PRx-1000-2 DSP series amplifier is a DSP-controlled class D 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.

System Design and User Operation

The units can be programmed with several system presets by the developer. End users are allowed to adjust room EQs, gains and delays and store user presets without touching the system presets. OEM customers can provide keyfiles to enable GUI features for end users.

The GUI provides an easy-to-use FIR creation tool. Measurements can be imported from various formats and overall latency can be defined.

The touch panel shows level meters, limiter operation and allows switching presets and inputs.
