- BTX will be showcasing its ProBlox system at InfoComm 09. As a cost-effective solution to bundling numerous signals, the ProBlox system combines 16 coax and 26 audio/data/control contacts in one multi-connector. This allows fast and simple set-up and tear-down in broadcast and AV applications, such as remote broadcasting, rental and rack staging, corporate settings, podiums, and more. BTX is releasing the latest addition to the ProBlox system with the new CV-PBVCM2 (male) and CV-PBVCF2 (female) coaxial contacts. These custom coax contacts allow integrators to use a number of widely used five-conductor mini high-resolution RGB cables with the ProBlox system. ProBlox is field-terminatable and custom-configurable for numerous combinations. It can be used anywhere HDTV, video, VGA, analog/digital audio, control signals, or DC power needs to be fed to a single location.
