Overview
1.1. Description
The VideoEase Audio-Video Hub allows up to two (2) baseband video signals and up to
two (2) audio signals to be distributed to up to eight (8) destinations via twisted pair
(UTP) cable for more cost-effective and versatile cabling.
The Audio-Video Hub when used in conjunction with MUXLAB’s line of VideoEase
baluns, allows coaxial cable to be eliminated between the Audio-Video source and the
destinations. For example, the product works with the VideoEase CCTV Balun (500000,
500009), VideoEase Stereo Audio/Video Balun (500001),VideoEase Dual Audio/Video
Balun (500012), S-Video Balun (500016) and S-Video/Audio Balun (500017).
The Audio-Video Hub allows CCTV and audio-video signals to be distributed to multiple
locations via standard twisted pair cabling instead of costly coaxial video cable or audio
cable.
A looping output allows the source input to be distributed to other baseband audio/video
equipment including matrix switchers, multiplexers, VCRs and monitors and other
VideoEase Audio-Video Hubs for greater versatility. The video and audio twisted pairs
are independent of each other and it is not necessary to use all of them in a given application. The Audio-Video Hub is designed for point-to-point configurations and further
expansion via cable tapping is not supported.
