The Soundcraft Aviom 16ch Output Card is an expansion module that enables compatible Soundcraft digital consoles (like the Vi and Si Series) to interface directly with Aviom's Pro16 Series Personal Mixers. This allows musicians on stage to receive up to 16 channels of audio (from the console's Aux or Group outputs) and create their own custom monitor mixes using their personal mixers. The card transmits digital audio and sync data over a single Cat5e cable, simplifying stage setups by eliminating the need for bulky analog monitor snakes.
