ARC is equipped with 2 locations for Dio modules. Dio modules allow different formats of audio digital data transmission. Today the DioES module enables use of Ethersound (64 bi-directionnal channels in a CAT5 cable). Several future modules will be developped and will provide other digital formats. Thanks to ARC, any Stage-Box can be easily converted to Diocore: just replace SCoptical or SC-64 modules by ARC.
