Processor dbx ZonePRO 640m

The dbx ZonePRO 640m is a multifunctional processor designed for professional installations in commercial and public spaces. It features a fixed configuration with 6 inputs and 4 outputs, including 4 balanced mic/line terminal block inputs and 2 unbalanced mono-summed RCA inputs. Microphone gain can be adjusted individually for each channel.

The 640m architecture includes input processing, a central routing matrix, and output processing. It offers two input insert points and one output insert point, allowing for task-specific processing customization. The AutoWarmth® feature is always active on each output zone, preserving full frequency response even at lower signal levels.

Thanks to the link bus, the first 6 audio channels can be duplicated to another ZonePRO device, enabling system expansion to additional output zones. The front panel includes a clear LCD display, signal level indicators, and user-configurable controls.

Additional control is available via optional ZC series wall controllers, providing easy access to volume, source selection, and preset recall. External control is supported via Ethernet or RS-232 and integration with third-party control systems is available.

The device is configured using the ZonePRO Designer software, which provides a step-by-step configuration wizard to assist in setup for specific installation needs.
