CB4055
3.12 Audio
The CB4055's audio functions are provided via a 2x8pin connector (FCI 98424-G52-16LF, mating
connector e.g. FCI 90311-016LF). This interface provides eight output channels for full 7.1 sound output.
Two microphone inputs and two AUX inputs are also available.
The signals "SPDIFI" and "SPDIFO" provide digital input and output. If a transformation to a coaxial or
optical connector is necessary this must be performed externally.
