RDL D-J3M Mic/Line Wall-Mounted Input Assembly with XLR and Mini-Jack Line Inputs

Install reliable, low-noise audio inputs wherever you need them. The Radio Design Labs D-J3M mic/line input assembly is a wall-mounted faceplate engineered for professional AV, security and surveillance installations. It accepts a female XLR microphone input and a stereo mini-jack line input, combining LEFT/RIGHT consumer signals into a transformer-balanced mono output that rejects induced hum — ideal for monitoring, public address, or recording feeds. The XLR is wired directly to the rear-panel barrier block for straightforward integration with mixers or 10 kΩ+ line inputs, while the rugged metal enclosure and 2.2" depth allow secure mounting in standard US single-gang boxes or optional RDL back boxes. Technicians and integrators benefit from reduced noise on long cable runs, a compact 1.7" x 4.1" footprint, and trouble-free wiring labeled for fast installs. Use the D-J3M in surveillance control rooms, conference rooms, or distributed audio systems to capture clear, balanced audio from both consumer and pro sources. Add the RDL D-J3M to your next security or AV project to simplify inputs and improve audio quality.
