The Inday AV4X-R is a 4-Input to 1-Output, 3 channel switcher. Two channels for Stereo Analog Audio and the third channel for Video or Coax Digital Audio.
The circuitry inside the AV4X-R uses only the best components for ZERO degradation of audio and video signals. The IC's used for each signal path are specifically designed for the type is signal being switched. The result is a very low noise/distortion and flat frequency response output for both Audio and Video.
Typical applications include combining 4 different A/V sources such as VCR's, DVD's and Camcorders to one common output.
