Allen Heath AH-M-SQ-SLINK-A 128x128 Channels SLink Network Interface Card SQ SLink provides engineers with the option to add an additional intelligent SLink port to any SQ console. With the same functionality as the built-in SLink port, the card allows connection to a further 128 inputs and 128 outputs of digital audio and opens the SQ to a range of new system possibilities. The option card runs independently from the built-in SLink port, allowing two different Allen Heath protocols to be used in one system, at the same time. With two SLink ports it?s now possible to combine an SQ with any ME personal monitoring system, DX, GX or dSnake expander. Any SQ console fitted with an SLink card can also be directly connected to a Qu, SQ, Avantis or dLive system, enabling FOH / monitor splits, broadcast feeds and more.
