Input/Output controls allow you to select S/PDIF or ADAT as the digital format for the optical input
and output connections, and to select between XLR or RCA connectors for the analog inputs.
Conversion between optical and coaxial (RCA) S/PDIF is possible by selecting S/PDIF OPTO and
S/PDIF RCA for input or output and vice versa. When Optical S/PDIF output is chosen, the RCA output
remains active, creating a digital Y-cord or signal splitter. (NOTE: this is not true of the inputs —both
S/PDIF inputs cannot be used at the same time.) You can however use ADAT OPTICAL and S/PDIF
RCA simultaneously.
De-Emphasis Select enables de-emphasis to be applied to the analog output. This function applies
only to the analog converter, and does not affect signals from the S/PDIF or ADAT interface.
SCMS/Copy Protection applies SCMS (Serial Copy Management System) coding to the S/PDIF
output. Choose Multiple Copies to encode the output for reproduction, One Copy to allow a single
digital 1-to-1 copy to be made from the S/PDIF output, or No Copies to prohibit any copies.
