The Kramer VM-30AV is an exceptionally high performance 1:3 distribution amplifier for video and stereo audio signals.

The VM-30AV uses RCA connectors for the video signals, as well as for the audio signals. The machine accepts one input and distributes the signal to three identical outputs. The VM-30AV is typically used for composite video sources such as VCR's, cameras, etc., but video bandwidth exceeding 430MHz allows the machine to be used for high-resolution data/video signals, SDI (serial digital) video, and other specialized signals. The machine includes a button control for audio level as well as trimmers for controlling video level and cable EQ. accessible via the front panels.

The VM-30AV is rugged, dependable, and is housed in a convenient small enclosure for desktop professional and home use, but can also be rack mounted using the RK-50RN kit, which holds two units in one vertical space of a standard 19" rack. The machine is fed from an external 12Volt DC source, and is therefore suitable for fieldwork as well.
