The ETS AV900WP, AV901WP and AV906WP have been redesigned with new flat circuit boards providing Baseband Video/Stereo Wall Plates which are utilized for point-to-point replacement of coaxial (video) and shielded (high impedance audio) cables with UTP wiring, Category 5 or better.
The AV901WP (with 3 RCA jacks for all inputs) is designed for installations that have a need for separate audio channels. For example, some VCRs and Video Cameras have video plus stereo outputs available on three RCA jacks. The AV901WP can run these signals using three of the four pairs in standard UTP cable.
AV906WP (with 4 RCA jacks for all inputs) allows you to send two channels each of baseband video and audio in any direction desired. This capability yields, for instance, a bi-directional video + mono audio link, or many other configurations.
You get the same high quality baluns with the addition of an enhanced appearance of wall plates, giving you a neater professional installation.
