The ZonePRO 640 from dbx is a digital zone processor that features six channels of input and four outputs. The unit is suitable for installation in restaurants, fitness centers, retail stores, nightclubs, and any other situation that requires multiple-zone control of audio sources with paging features. The ZonePRO 640 has limited front-panel control, but both it and the ZonePRO 641 (same features, but with no front-panel control) require a computer for initial setup.

The processor provides two balanced inputs on Euroblock terminals that are selectable as line or microphone level (with phantom power), along with four pairs of analog RCA line inputs, with each pair internally summed to mono. Outputs are available via Euroblock terminals and can be configured as either stereo or mono. Front-panel control includes zone output volume, source select, and muting for each zone. Output level meters with six-segment LED meters and output dynamics threshold LEDs provide visual feedback of signal levels.

The included Windows-based control software communicates with the unit via RS-232. Processor blocks can be switched in or out of a chain and include input gain, high-pass filtering, parametric EQ, compression, limiting, gating, AGC, ducking, de-essing, AFS (Advanced Feedback Suppression), notch filters, signal routing, band-pass filtering, delay, and polarity. An AutoWarmth module provides gentle bass boost compensation as signal levels are lowered.

The ZonePRO 640 really shines when utilized with optional remote wall-mount controllers (sold separately) that can be positioned within the various zones. The wall-mounts are able to provide local volume control or scene selection, dependent on the type of controller installed. A built-in real-time clock can provide programmable system changes throughout the day or week. All program memory is non-volatile, ensuring program security in the event of power failure or computer malfunction.
