This design allows the user to select one of four sources to feed a single input such as a video monitor or recorder. Each channel provides a composite video input with stereo line-level audio which are switched simultaneously by buttons on the front panel. A range of mounting accessories is available for the Radio Design Labs EZ-series.

The EZ-Series offers a wide range of stand-alone designs including distribution amplifiers for line level audio, headphones, composite and XGA/XGA video, audio pre-power and mixer amplifiers, AV input selectors and computer video selectors. All models may be connected and operated without the use of tools, using standard cables. They are housed in enclosures with the same height, with widths in increments of one sixth of a rack-width, so they may be mounted singly or in multiples in a range of accessory mounts. Audio and video are switched using solid-state circuitry to avoid degradation due to dirty switches; critical connectors are gold-plated for reliable connections. All use 24 volt power, supplied from external AC adapters.


The front panel has four push buttons to select one of the four sources. An LED indicates when power is present. The rear panel has four pairs of RCA(phono) sockets for the connection of the audio sources, and pair of similar sockets for the audio outputs. There are five further RCA(phono) sockets for the four composite video inputs and the selected video output. A locking co-axial connector provides the power input.
