Visual Sound AF-TPR3C 音视频接口

RDL, Radio Design Labs","The TPR3C modules are three-pair audio receiving modules compatible with RDL® Format C twisted pair products. These modules are designed to be mounted in wall boxes, cabinets or other enclosures that allow users to connect external equipment. The D and DS models mount in RDL WB-1U and WB-2U wall boxes, or in standard U.S. electrical boxes. The D-TPR3C features a white front-panel laminate with gray lettering that matches RDL Decora®-style remote controls. The DS-TPR3C is constructed of stainless steel to coordinate with RDL Decora-style stainless steel remote controls in commercial\/industrial installations. The AF?TPR3C is an APPFLEX™ series product that is compatible with various APPFLEX wall-mount, cabinet-mount and tabletop enclosures. The EM-TPR3C is a 45mm square module that fits the European Modular mounting frames and cover plates. European electrical boxes are not sufficiently deep to accommodate RJ45 jacks and plugs, therefore the EM product connects to the twisted pair cable through a detachable terminal block.The TPR3C modules feature an RCA phono NTSC or PAL video output and two RCA phono jack audio outputs, one for the left channel and one for the right channel. The video signal received from pair A of the RJ45 INPUT jack feeds the RCA video output jack. A concealed GAIN control is provided to recover any video level loss over the twisted pair cable. An EQ control allows the installer to adjust the sharpness of the picture for high frequency losses in the cable. The audio signals received from pairs B and C of the twisted pair cable are buffered to drive the RCA audio output jacks at the standard -10 dBV consumer level. The TPR3C modules terminate the video cable pair, therefore additional receivers may not be connected to the same twisted pair feed. The TPR3C may be powered directly from a 24 Vdc power supply using the rear-panel detachable terminal block. Local power connected to the module is also fed to all connected remote modules. The ?TPR3C may be remotely powered through the twisted pair cable from any other module, signal distributor or RDL power inserter connected to the same twisted pair cable. Module power is indicated by a front-panel LED.RDL Format-C provides quality balanced video transmission over long distances, and features superior audio performance that rivals or exceeds shielded wiring.
