18i8 only – S/PDIF Source: this model accepts a S/PDIF signal at either the RCA connector or the
optical ADAT input port. Note that when the optical port is used for an S/PDIF input, it cannot be used
for ADAT inputs. Also note that the optical ports are disabled at sample rates of 176.4 and 192 kHz.
18i20 only – Digital I/O Mode: this model supports three different Digital I/O Modes, which
determine how the interface’s S/PDIF input and output, and the four optical ports, function. The
mode to be used is selected from the Digital I/O Mode dropdown. The three modes are:
• S/PDIF RCA – this is the default mode: the 18i20 will send and receive S/PDIF signals via the
coaxial connectors.
• S/PDIF Optical – use this mode if you need the 18i20 to send or receive S/PDIF signals via
an optical connection. If you have selected S/PDIF as the clock source (see above), then the
18i20 will use an S/PDIF signal applied optically at an ADAT port as the clock source.
• Dual ADAT – this mode lets you send and receive eight channels of audio via the ADAT ports at
88.2 or 96 kHz sample rate. Note that in this mode, S/PDIF I/O is disabled at all sample rates,
and will not be available at either the RCA connector nor via an optical port.
Further details can be found in the section “Digital I/O Modes” in the Scarlett 18i20 User Guide.
