Incompatibility Between Mico SPDIF Output and Tascam Recorders
When using SPDIF to connect an Audient Mico and a Tascam recorder you will get a DIN Unlock error. This is because the Tascam units do not currently support incoming 'Professional' SPDIF signals. As this Professional Bit is hardwired on a Mico, and the tascam units do not have a setting to allow a professional SPDIF signal to be recieved, the units are incompatible.
Connecting Mico's AES output to AES inputs on Tascam units should work perfectly.
