Upon frequent request we added an S/PDIF RCA output to the MU1, that sits next to two AES3 XLR outputs and an LS1 cat5 output. The RCA will carry a copy of the digital audio of the LS1 output. Up until now, customers with an RCA equiped DAC would need to use an impedance corrected conversion cables like our AES to S/PDIF cable. For new MU1 customers that is soon not necessary anymore.
New customer, please mark that this new feature will be enabled with an upcoming firmware update later this month.
