Designed for Installed Audio Performance

With the release of 4REA4, DiGiCo is pushing the boundaries again with a new audio installation platform designed to deliver the highest quality performance across multi-space venues and stages.

At the heart of the system is the 4REA4 processing engine with DiGiCo connectivity options and powerful 4REA4 control software, providing routing, processing and mix control that allows your performance area to expand across your installation.

Managing, Mixing & Routing Your Audio

DiGiCo has been at the heart of live performance audio for over 15 years, creating digital consoles used by engineers the world over, who want the best in sound quality, usability and reliability. From the biggest live tours to the largest houses of worship and theatres, DiGiCo has been shaping the future of digital live sound that has transformed how live engineers mix.

4REA4 Processing Engine

The processing engine rack has four dedicated mix areas, or zones, each with its own stereo master output, CGs, and allocated FX. Plus, with 128 input channel and 48 buss output processing strips available you can independently allocate processing to whichever area as required.

4REA4 External I/O & Control

Managing the mixing and routing of each individual performance area are a new range of premium designed hardware control panels and external I/O units with intelligent labelling and visual feedback, that work in conjunction with the 4REA4 processing engine and control software.
Performance Venues

Performance Venues

4REA4 is made for multi-area performance venues where managing and delivering the best audio quality and experience is paramount. Control and mix all areas of live audio performance from your main auditorium or stage, to smaller public areas and even backstage, with a range of dedicated I/O and mix panels. Manage multiple show configurations for the same space with the 4REA4 control software and switch setups for I/O and routing in an instant with no downtime, ensuring every show is on schedule and ready to go.

Audio Matrixing

Audio Matrixing

Taking the strain for shared stages at festivals and large music venues, 4REA4 can be configured as a powerful matrix mixer for managing multiple live consoles for different acts. Analogue or digital mix feeds can be taken directly from any DiGiCo or 3rdparty console, and PA routing can then be switched or mixed without the stress and complication of re-routing consoles on the fly.

House Of Worship

House Of Worship

A trusted live console partner for many house of worship clients around the world, 4REA4 allows ministries to expand how each section of the congregation can enjoy their service experience. Any breakout room or space can have full access to the main service, whilst still having full control of managing and mixing additional localised performance material. Plus, with the intuitive control software and dedicated function keys, switching between different service layouts is as simple as pressing a button, ensuring ease of operation for all volunteer and dedicated staff.



Leading the way with dedicated console theatre functionality and audio performance, 4REA4 expands the DiGiCo install experience providing the ultimate in personal monitoring for musicians and general purpose automation control. Now any member of the orchestra or stage ensemble can have direct pristine personal monitoring control of the live DiGiCo FOH feed, balanced and adjusted for their exact requirements including in-ear monitoring feeds. Keeping the performance on cue, 4REA4 can also provide general purpose I/O control of 3rd party hardware for all theatre automation requirements including curtains, lights and audible alarms.
