Chapter 3 Connecting power and devices
You can connect an external audio system to the display using the stereo 3.5 mm out connector
(pictured). Alternatively, you can connect an external audio system directly to a room computer.
SBID-7000-V2
In addition to the stereo 3.5 mm out connector, the display provides a Sony/Philips Digital Interface
(S/PDIF) out connector. S/PDIF is a digital audio transmission medium. You need an audio receiver that
supports S/PDIF to decode this connection to analog for use with an external sound bar or other audio
system.

Note
The S/PDIF out connector is a fixed-volume output. Adjusting the display's volume for its internal
speakers does not affect the volume output of the S/PDIF out connector.
