{"product_id":"rdl-fp-mx3r","title":"RDL FP-MX3R – Remote-Controlled 3-Channel Line-Level Mixer","description":"\u003ch2\u003eWhat is the RDL FP-MX3R?\u003c\/h2\u003e\u003cp\u003eThe RDL FP-MX3R is a 3-channel line-level audio mixer whose input levels are adjusted from an RDL wall-mounted remote control. Audio stays at the equipment location while users adjust the mix over standard twisted pair cable, using VCA circuits for each input. Balanced and unbalanced outputs, including two RCA outputs for a stereo amplifier, make it simple to integrate with commercial amplifiers. It is a practical choice for meeting rooms, training rooms and multi-purpose spaces where users need simple source level control.\u003c\/p\u003e\u003ch2\u003eHow does it work?\u003c\/h2\u003e\u003cp\u003e\u003cimg src=\"https:\/\/rdlnet.com\/wp-content\/uploads\/2024\/01\/fp-mx3r.jpg\" alt=\"RDL FP-MX3R remote controlled line-level mixer\" style=\"max-width:100%;height:auto\" loading=\"lazy\"\u003e\u003c\/p\u003e\u003cp\u003eEach of the three inputs accepts balanced or unbalanced line-level audio through a detachable terminal block, and each has a front-panel INPUT GAIN trimmer. Inputs are normally set to produce +4 dBu on the dual-LED VU meter with the remote at maximum, which leaves more than 18 dB of headroom. The mono mix is available on a balanced terminal block and on two unbalanced RCA jacks intended to feed the stereo input of a power amplifier. RDL remote controls connect to the light-blue RJ45 control port with standard twisted pair cable, and the mixer powers the remote. A two-channel remote such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-d-rc2\"\u003eRDL D-RC2\u003c\/a\u003e or a three-channel remote such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/rdl-d-rc3\"\u003eRDL D-RC3\u003c\/a\u003e can be used; with a two-channel remote, input 3 stays at a fixed level for paging or music, or can be disabled. If the remote cable is disconnected, the mixer output mutes. An AUDIO LED and two open-collector AUDIO DETECT outputs signal when audio is present, so they can switch amplifiers on or mute amplifiers equipped for remote muting. The detector outputs stay triggered for 10 minutes after audio stops, or 20 minutes with a ground jumper, which helps save energy in unused rooms.
