RDL DB-J3 Mic/Line Input Assembly, XLR, RCA, Terminal Block, Black

Optimize audio capture and integration for security, surveillance, paging and monitoring installations with the Radio Design Labs DB-J3 Mic/Line Input Assembly. This faceplate module puts a professional XLR microphone input on the front panel alongside two gold-plated RCA phono jacks for mono or stereo consumer sources. Unbalanced RCA inputs are combined and balanced through transformer isolation to reject induced hum, delivering a clean balanced mono output on the rear terminal block for connection to 10 kΩ or higher inputs.

Housed in a durable black metal enclosure and sized to fit standard US single-gang boxes (or RDL WB-1U back boxes), the DB-J3 simplifies installation in cabinets, walls, or racks. At 4.1" x 1.7" x 2.2" and weighing under 6 oz, it provides enterprise-grade performance without adding bulk. Gold-plated contacts improve signal reliability in critical monitoring and AV systems, and a one-year limited warranty supports commercial deployments.

Specify the Radio Design Labs DB-J3 for dependable, low-noise audio input in surveillance, security and monitoring projects — a ready solution for clean mic and line-level integration. Order now to streamline your next installation.
