DBX 640MV 6x4 Audio Distribution Processor with Pre-built chassis and intelligent control for commercial audio systems

• The dbx ZonePRO 640MV digital zone processor is a practical and professional solution for managing audio in commercial environments that demand reliable connectivity, ease of operation, and precise control of audio zones. This version features a pre-configured processing architecture that reduces programming time while maintaining the processing power and audio quality for which dbx is known.

Technical description:

• The ZonePRO 640m audio distribution processor is based on a robust and well-designed processing architecture that includes input processing, a central routing array, and advanced output processing. It features 6 inputs and 4 outputs with high-quality microphone amplifiers whose gain can be directly controlled via hardware gain control.

• The device provides customizable Insert points (two on the inputs and one on the outputs) to add external processors as needed, with permanent support for AutoWarmth® technology on each output area, which maintains the natural extension of low frequencies even at low volume levels, providing comfortable and balanced listening in all conditions.

• Link Bus also allows the first six channels to be copied to another ZonePRO device, which is an ideal option for expanding the system when a larger number of output zones are needed.
