The Monacor PA-4125DX is a 4-zone multifunctional amplifier featuring Class D technology and an integrated Digital Signal Processor (DSP). It is designed for general multi-room Public Address (PA) applications, offering flexibility in output configuration and network control, and is highly similar to the PA-8125DX but with fewer zones.
4-zone multifunctional mixing amplifier, class D technology with DSP and professional features for general multi-room PA applications. Clearly arranged graphical user interface HTML5 with extensive functions. Convenient operation via web browser regardless of the operating system used by the end-user device (PC, Mac, iOS, Android, etc.).
