The Comprehensive/Kramer 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 separate the signal back into composite video and stereo audio when used with the VA-12 separator.
Bandwidth
A wide bandwidth is offered for clean signal passage.
Compact Size
This device is small enough so two units can be mounted in a one rack unit space.
