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 Mix Rack 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 Mix Rack, 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.

1.1 dLive Surfaces
There are different sizes of dLive Surface available. The CTi-1500, C1500, C2500 and C3500 feature the same I/O and differ only in the number of faders and touchscreens. 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
