Product Description

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. Design simplicity, ease of installation, unsurpassed flexibility, automatically fused power, exceptional hum rejection, low noise, and low distortion provide designers and installers the optimum choice in economical twisted pair products.

8. Who Pays Customs Charges and Tarrifs if I Am An International Order ?
It is very important to consider the effects of tariffs, taxes, port handling fees and other miscellaneous customs charges when determining your product's final cost. Depending on your product and country of destination, customs charges will affect the price you the buyer is willing to pay for your product. The importer (buyer) is responsible for paying these charges and Avalive will not be responsible for this .

9. Who Warranties My Product Purchase ?
AValive is an authorized USA dealer for all the products we sell. There for you the buyer are entitled to the full USA manufacture warranty per item as supported directly from the manufacture. You are responsible for contacting the manufacture if the item is defective. The item needs to be returned directly to the manufacture NOT AValive. Simply call the manufacture with your serial # and follow their steps in the warranty process. AValive is not responsible for items shipped to us with out an AValive RMA # and shipping such to us may result in you never seeing the product again.

10. Why does the product price say 'Click for best price'?
Often times manufacturers do not want any price other than MAP or Minimum Advertised Price to be listed in any form of e-commerce or advertising. Because AValive believes in the American Way we feel we should determine what price you pay not someone else. AValive has the legal right to set our own prices independently, but some manufacturers place restrictions on how those prices may be displayed. Because our price on this item is lower than the manufacturer's "minimum advertised price," the manufacturer does not allow us to show you our price until you take further action, such as placing the item in your shopping cart, or in some cases, proceeding to the final checkout stage or emailing. The steps required depend on the details of the manufacturer's minimum advertised price policy. AValive won't require you to purchase the product. You can easily remove it from your cart if you decide not to buy it and no further information is kept.

11. Will I Pay Sales Tax ?
All orders shipped to NC will be charged NC Sales Tax unless you are a reseller which will require a NC Dept Of Revenue Exemption Form to be faxed to us. Almost all other states we ship to will not be charged sales tax with the only exception being some direct ship from warehouses located in the state to which the product s shipped to.
