ZonePRO: an "installation" approach designed for multi-source distribution

The ZonePRO range includes digital processors dedicated to fixed installations, designed to centralize sources, organize zone distribution, and apply necessary processing to protect the system. In this context, the 6 x 4 version without display favors discreet rack integration and control via programming, while maintaining connectivity suited for professional environments (RCA for consumer players, Euroblock for balanced connections).

Who is this 6 x 4 processor for?

This processor is particularly suited for operators and integrators who need to manage multiple sources (background music, TV, media player, event microphone, DJ line) and feed multiple distribution outputs, with consistent control over time. It is ideal for venues requiring quick commissioning and simple daily operation, while maintaining lockable settings to prevent handling errors.

DSP Processing: protection, intelligibility, and operational comfort

Once analog signals are converted to digital, the internal DSP applies a wide range of processing to meet the real needs of an installation: optimizing sound quality, level management, speaker protection, and diffusion consistency. The goal is twofold: enhance the listening experience (clarity, tonal balance, zone coherence) and secure the audio chain (saturation prevention, dynamic control).

Mixing and routing tools

The ZonePRO allows assigning different inputs to outputs according to usage scenarios (ambiance, microphone announcement, event). This flexibility facilitates multi-source management, including when multiple contents must coexist in the same space, with controlled levels and priorities.

Essential processing for installation

Features include mixing, feedback eliminator, automatic gain control, compressor, limiter, noise gate, notch filter, high-pass and low-pass filters, crossover, parametric equalizer, as well as function locking to secure operation.

PC programming and program recall

Configuration is done via a PC, then the device operates autonomously. Depending on the site organization, programs (source, level, assignments) can be recalled to quickly switch from one context to another. Flush-mount wall remotes can also be used for program recall, convenient for "staff" use without access to the rack.
