RDL D-J1 Mic Input Assembly-XLR Terminal Block

Optimize your AV and security installations with the Radio Design Labs D-J1 microphone input assembly. This wall-mounted mic input panel provides a professional, front-panel female XLR connector with gold contacts for low-noise, reliable audio. Behind the panel a clearly labeled rear barrier block presents four terminals (CASE GROUND, SHIELD/pin 1, +/pin 2, -/pin 3) so installers can wire quickly and use the ground-lift option when needed to eliminate hum or ground loops. The D-J1 fits standard single-gang electrical boxes or RDL WB-1U back boxes and features a sturdy metal enclosure for long-term durability. At just 2.2" depth and lightweight construction, it integrates cleanly into conference rooms, paging, monitoring, and surveillance audio systems. Ideal for AV integrators, security contractors, and facility managers, the D-J1 streamlines microphone connectivity while maintaining professional audio integrity.
