The MSC-DE3248 32 x 48 AES Audio Router from Matrix Switch Corporation uses the AES-3id (SMPTE 276M) standard that defines a 75-Ohm BNC electrical variant of AES3. It supports all AES audio rates up to 192 kHz and can use the same cabling, patching, and infrastructure as analog video, or it can be digital switcher designed for AES data rates and a 700mV to 1V input-output interconnect. This router is designed for use as a secondary level to one of Matrix Switch Corporation's video routing switchers with a D25 AFV or AUX connector.
