Coaxial RG-6 cables are ideal for making line-level connections between components in multi-room installations. Compared to RCA patch cords, they're inexpensive and more resistant to interference. These Niles adapters let you hook up the F-type connectors on your longer runs of RG-6 cable to shorter RCA-type patch cords connected to your components. They're designed to fit in Niles's MB-series connection plates, for neat in-wall installations.
Plan on using one adapter for each connection. For example, if you're running stereo audio, that'll take two adapters one for each channel. Likewise, a video connection will require its own adapter.
