Get the necessary inputs to connect your new entertainment devices when your existing TV doesn’t have them. The Best Buy essentials BE-HCL312 RF Modulator is compatible with TVs that don’t have AV input jacks, converting line-level composite video or analog stereo audio signals to RF coaxial. With this modulator you can connect AV devices like Blu-ray players, gaming systems, and more. When you’re done with your AV (composite) device, simply turn it off and your TV will automatically switch to your cable or antenna, which you can connect to the additional RF (coaxial) input. Backed by Best Buy, let us accommodate your TV to connect to your new entertainment devices, so all you have to do is sit back and enjoy.
