dbx DBX-640VVM dbx ZonePRO 640 6-Input/4-Output Digital Zone Processor with Front-Panel Control, 20Hz to 20kHz Frequency Response

Bring consistent, professional audio control to commercial and security deployments with the dbx by Harman DBX-640VVM ZonePRO 640 digital zone processor. Built as a pro audio processor, the 640 gives integrators fast, dependable control over six inputs and four outputs with a 20 Hz–20 kHz frequency response and front-panel control for on-site adjustments. Its advanced DSP — including AutoGain, patent-pending AutoWarmth for natural low-frequency extension, and Advanced Feedback Suppression — improves speech clarity for paging, surveillance announcements and monitoring stations. Priority paging, source ducking and selectable mic processing (gating, de-essing, compression) ensure emergency or security voice messages cut through background music without operator intervention. Installer-focused features like Euroblock and RCA connectivity, wall-mount form factor and network-compatible control options speed deployment and allow scalable multi-unit systems. Ideal for retail, corporate AV, security and surveillance audio systems, the ZonePRO 640 delivers consistent sonic performance and control. Contact your integrator or add the dbx ZonePRO 640 to your next specification to streamline commercial audio and monitoring installations.
