Audio connections – Gina24
S/PDIF
Next to the ADAT connectors is a pair of connectors labeled S/PDIF, IN
and OUT. These connectors are used to transmit digital audio data via an
electrical signal. S/PDIF data can use the full 24-bit sample width used
internally on Gina24.
When connecting devices to the S/PDIF jacks on Gina24, the use of standard
analog RCA audio cables is not recommended. For reliable S/PDIF
operation, 75ohm coaxial (RG59) video cables are recommended.
