ANALOG OR DIGITAL INPUT MODULE
The Analog version controls preamplified microphones or analog line-level sources on both inputs. The digital
version controls AES-3 or S/PDIF digital sources on both inputs. Input modules can be reconfigured in the field
by changing the plug-in SIM card. The functional differences for the digital version are listed within brackets.
