COMPOSITE & AUDIO COMBINER ON SINGLE COAX The VA-11 is a high performance combiner of composite video and unbalanced stereo audio signals. It combines the composite video and stereo audio into a single signal which allows the use of a single coax cable, which can then separates it back into composite video and stereo audio when used with the VA-12 separator.

    * Bandwidth - 7MHz (- 3dB).
    * Inputs - 1 composite video and 1 unbalanced stereo audio.
    * Outputs - 1 single signal of the combined audio and composite video.
    * Desktop Size - Compact size. Two units can be rack mounted side-by-side in a 1U rack space with the optional RK-50RN.
