DBX ZonePro 640m 6x4 Digital Zone Processor

The ZonePRO 640m stands out as a sophisticated audio processing solution that combines fixed I/O architecture with flexible insert processing capabilities. This professional-grade device features six inputs comprising four balanced mic/line switchable terminal block inputs and two mono-summed pairs of unbalanced RCA inputs, alongside four outputs for comprehensive audio routing. Hardware-controlled microphone gain provides precise adjustment of microphone levels per channel, giving you complete control over your input signals.

Built around a pre-configured architecture that includes input processing, central matrix, and output processing stages, the 640m offers two input insert positions and one output insert position for channel-specific processing customisation. Each output zone benefits from AutoWarmth®, a psychoacoustic function that maintains full frequency bandwidth even when signal levels drop, ensuring consistent audio quality across all zones.

For applications requiring additional output zones, the integrated link bus allows duplication of the first six audio channels to another ZonePRO device, providing scalable solutions for larger installations. This feature makes the 640m particularly valuable for venues needing to expand their audio distribution without compromising signal integrity or processing quality.
