RDL DB-J3M Mic / Line Input Assembly, Wall Mounted

Optimize audio capture for security, surveillance, and monitoring applications with the Radio Design Labs DB-J3M Mic/Line Input Assembly. This pro wall plate places professional-grade inputs at the operator’s fingertips, offering an XLR mic input and a 1/8" mini-jack line input so technicians can connect microphones, recorders, or auxiliary sources quickly. Built-in hum cancellation and transformer isolation keep signals clean and free from ground loop noise, while the balanced mono output (via a terminal block) maintains signal integrity over long runs to mixers, recorders, or PA systems. Housed in a durable metal, wall-mounted enclosure with clear labels, the DB-J3M reduces installation time and stands up to the demands of control rooms, surveillance centers, and AV installations. Designed by Radio Design Labs for professional environments, this pro wall plate delivers consistent, high-quality audio where it matters most. Add the DB-J3M to your next project to streamline input access and improve monitoring accuracy in security and surveillance deployments.
