The ETS InstaMusicianâ„¢ Balun (model no. SDS904) enables both audio and composite video signals to be sent over a single Cat5 or better cable. This audio/video balun is a compact, versatile, and passive component that has bi-directional capability.

NOTE: The image above is for illustrative purposes and shows both the InstaMusician SDS904 and SDS903. This model is the SDS904 only. The SDS903 is sold separately .
