S/PDIF Digital I/O
The S/PDIF in and out ports are unbalanced two-
conductor phono (RCA) connectors that utilize
a full 24-bit, two-channel digital data stream.
The Sony/Philips Digital Interface Format
(S/PDIF) is used in many professional and con-
sumer CD recorders and DAT recorders. To
avoid RF interference, use 75-ohm coaxial cable
for S/PDIF transfers and keep the cable length to
a maximum of 10 meters.
MIDI I/O
The MIDI In and MIDI Out ports are standard
5-pin MIDI ports, each providing 16 channels of
MIDI input and output.
