{"product_id":"rdl-fp-tpx3a","title":"RDL FP-TPX3A – Format-A Remote-Controlled 3-Channel Mixer","description":"\u003ch2\u003eWhat is the RDL FP-TPX3A?\u003c\/h2\u003e\u003cp\u003eThe RDL FP-TPX3A is a 3-channel remote-controlled mixer that accepts RDL Format-A twisted pair audio senders directly. It lets users adjust the volume of several sources in a zone from an RDL wall remote while the audio stays at the equipment location. Balanced and unbalanced outputs, including two RCA outputs for a stereo amplifier, simplify amplifier integration. It suits classrooms, meeting rooms and multi-purpose spaces that use Format-A wall plates for mic and line inputs.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/fp-tpx3a.jpg\" alt=\"RDL FP-TPX3A Format-A twisted pair remote controlled mixer\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eTwo Format-A RJ45 jacks accept signals from daisy-chained senders or from two separate home runs, and the mixer powers all connected active senders. The mixer combines the three Format-A signals on pairs A, B and C, and a detachable LOCAL INPUT terminal block can feed pair C with a local paging or music source when no sender uses it. Each INPUT GAIN control is calibrated for passive unbalanced senders in one direction and for active or balanced passive senders in the other. A dual-LED VU meter shows the mono mix level, which is available on a balanced terminal block and on two RCA jacks for a stereo amplifier. RDL two- or three-channel remotes such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-d-rc2\"\u003eRDL D-RC2\u003c\/a\u003e or \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-d-rc3\"\u003eRDL D-RC3\u003c\/a\u003e connect over twisted pair to the light-blue control port and are powered by the mixer. With a two-channel remote, pair C stays at unity gain for paging or can be disabled, and the output mutes if the remote cable is disconnected. Two open-collector AUDIO DETECT outputs can turn amplifiers on when audio is present or mute amplifiers equipped for remote muting. These outputs stay triggered for 10 minutes after audio stops, or 20 minutes with a ground jumper.
