Adapters

Adapters are great for connecting an audio or video source, so you can listen or view your program. Video connections may require a video converter to work properly. Please see our Video Converters for assistance with your selection.

Identifying the right connector is critical for selecting the correct adapter. Here are some of the common connectors, configurations and their usage:
