dbx 641 overview

  • 1Description

The ZonePRO 641 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 641 has no front-panel control and requires 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. A DB-9 connector is located on the front panel for connecting to a computer.

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 641 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.

Note: Stereo sources and stereo output can be configured using the control software, but input channels and number of zones available will be reduced correspondingly.

    dbx 641 reviews

    ZonePRO 641 Digital Zone Processor without Front-Panel Control is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Great simplicity for end users. It does what it says it does. Drivers downloaded easily into win10 computer. Setup Wizard takes the guess work out of setting it up. The only negative comment would be regarding the serial port for programming. Had to purchase a usb adapter. Not that it was a big deal but a usb port would have been more convenient.
