Introduction

dLive is a distributed digital mixing system providing a uniquely flexible solution for any live sound application. It separates the mix engine from the control surface, putting the audio and processing where it is needed, and offering a host of control and audio networking possibilities. Refer to the Allen & Heath website to find out more about dLive.

The MixRack is the heart of any dLive system. It houses the XCVI processing core complete with audio I/O, control and audio networking ports. The Surface is effectively a network controller for the MixRack, with the addition of built-in audio I/O and audio networking ports. DX Expanders can be added to the system for extra I/O.

dLive Surfaces

There are different sizes of dLive Surface available. The C1500, C2500 and C3500 feature the same I/O and differ only in the number of faders and touchscreens. The CTi-1500 is functionally equivalent to the C1500 but engineered with titanium sides and aluminium panels for lightweight applications. The S3000, S5000 and S7000 offer more I/O, an extra I/O Port, redundant power supplies and dual redundant gigaACE and DX connections. Refer to their Getting Started Guide for further detail.

dLive Surface features at a glance:

• Fully assignable layout
• Single or twin 12” capacitive touchscreen
• Gesture control – pinch, swipe, drag ‘n drop
• Configurable widget areas for Scenes, meters, FX and more
• 19 assignable SoftKeys (26 on S3000, S5000, S7000)
• Engineer’s Wedge and IEM fader strips
• Comprehensive multipoint metering
• Daylight visibility
• USB stereo recording and playback
