Profile itself is just a control surface that must be used with either local and remote stage racks, or with one Mix Rack that combines processing and inputs/outputs. Mix Rack is essentially a SC48 without control surface. The SC48 is all-in-one box VENUE system, where all processing, inputs and outputs is built into console. This feature allows it to 'drop into' existing wiring systems where an analogue console had been used. Outwardly it appears quite similar to a smaller version of the Profile, and was introduced as the 'starter' console in the range. Recently a remote rack option became available for SC48, either add-on to existing system in form of an empty rack where user can relocate I/O boards from main SC48 unit, or order new system (SC48 with remote stage rack) with remote I/O preinstalled. As with its larger predecessors, the SC48's master output section can be configured as Left–Center–Right or Left–Right plus Mono. The control surface has 26 motorized faders: 16 to address banks of inputs and effects returns, one to link to any desired input, eight to address banks of outputs and VCAs, and one to control master output. An expansion slot at the rear panel allows one of several options: 16 analog outputs can be added; eight analog and eight AES3 digital outputs can be added; or A-Net connectivity can be achieved with external Aviom Pro16 personal monitor mixers. VENUE | S3L-X was introduced in 2013 and features the smallest footprint of any VENUE console, with 16 faders and 32 knobs. The modular system was Avid's first live console to be built on an Ethernet AVB architecture that connects the S3 control surface, up to four Stage 16 I/O racks, and the E3 Engine over Cat5e cables. The system can support up to 64 inputs and was the first VENUE system to enable the sharing of I/O between systems over the Ethernet AVB network. A unique feature of the system is that the S3 control surface can be used as a standalone DAW mixer using Avid's EUCON Ethernet control protocol, which is supported by Avid Pro Tools and Media Composer applications as well as Steinberg Cubase and Nuendo, Apple Logic, and others. Avid released its new flagship VENUE | S6L live sound system in 2015, which effectively replaced earlier D-Show and Profile systems at the top of its live sound range.
