Here you can find a handy and cristalclear comparison chart of the technical specs from SC48, Profile systems and D-Show system.

SC48 is the definitive, all-in-one live sound solution, combining all I/O, digital signal processing, and tactile control into one compact console, making it the most affordable and portable VENUE system yet.

Stage Rack serves as a remote I/O component of the VENUE live sound system for stage connections.

FOH Rack serves as the central processing component of the VENUE live sound system. Generally positioned near the control surface, FOH Rack houses an embedded control computer and DSP Mix Engine cards, with room for additional hardware option cards, providing connectivity for local inserts and outboard devices.

Mix Rack is the key component to the most affordable VENUE system. As an alternative to employing a local FOH Rack and remote Stage Rack in a system, the 11-space Mix Rack combines all stage and local I/O, computer control, and processing power into a single compact enclosure.

The VENUE D-Show System is based around the VENUE D-Show console and employs a VENUE FOH Rack and Stage Rack processing and I/O system. This system offers the greatest amount of I/O and console expandability, enabling it to accommodate even the largest ensemble performances.
