Analog audio over  CAT6/6A Shielded wiringThe MX TX4 and RX4 act like a typical four-channel analog audio snake; they allow you to send mic or line-level signals from one location to another without signal loss, noise, or interference, and without any digital audio conversion needed. What makes the MX system unique is that it utilizes CAT6/6A Shielded Shielded Ethernet cable, which is widely available, lightweight, and economical. Simply connect a shielded CAT6/6A Shielded cable between any two MX modules and they will use the analog conductors in the cable to deliver four balanced audio lines to any destination.Straight-wire passive operationMX modules require no power to operate, and since they keep the signal in the analog realm, no digital conversion is necessary. Straight-wire connection from the XLRs to the RJ45 connector on a Cat 5/6 shielded  cable ensures that your audio passes through without coloration or distortion.Utilize pre-existing cable installationsAs many buildings are already pre-wired for Cat CAT6/6A Shielded cable, you can take advantage of this to transmit audio between distant rooms without the need to install or supply new cabling. This eliminates the need for bulky and expensive multi-channel audio cable, and allows contractors to benefit from installed network cable and easily connect from one room to another.4 CH Balanced Audio XLR Male To Female support 4 Channel balanced audio 16-bit digitally encoded broadcast quality balanced audio over one Cat 6/6A Shielded Cable. These XLR transmitter and receiver are typically used in applications for Rental, Staging, Theater, Stadiums, Theme Parks, Broadcast/Studio, CCTV audio and Professional AV applications, etc, and are available for stand-alone or rack-mount installations. Plug and Play design ensures adjustment-free installation and operation, and other adjustments are never required.
