Zone 4 Audio controller with DSP and WebApp
Compact
The Zone 4 is a powerful 4-zone audio controller with built-in Digital Signal Processing (DSP), designed to act as the central hub of your commercial sound system. It enables independent control of volume, source selection, and EQ across multiple zones, making it ideal for environments such as hospitality, retail, and leisure venues. With versatile connectivity including line inputs, SPDIF, microphone inputs, and HDMI, the Zone 4 ensures seamless integration with a wide range of audio and video sources, while advanced DSP delivers clear, high-quality sound throughout your space.


Zone 4 is a zonal audio controller with DSP providing everything required in a single compact unit to become the beating heart of an efficient, high-quality multi-zoned commercial sound system.
