RDL DB-J2 Series Wall Mounted Line Input Assembly, Black

Enable clean, hum-free audio capture at security stations, control rooms and monitoring sites with the Radio Design Labs DB-J2 Wall Mounted Line Input Assembly. This compact faceplate module converts two consumer-level phono inputs (mono or stereo) into a transformer-balanced line-level output, delivering superior rejection of induced hum and RF interference for clearer recordings and live feeds. The DB-J2’s balanced output mates directly with 10 kΩ or higher line inputs on mixers, recorders, or surveillance DVRs, simplifying integration into pro audio, surveillance and paging systems.

Built for installers, the DB-J2 fits standard US single-gang electrical boxes and includes a durable black metal enclosure with a clearly labeled rear terminal block for tidy, reliable wiring. At just 4.1" high and a 2.2" depth, it occupies minimal space inside cabinets and wall runs while providing professional-grade isolation via audio transformers. Ideal for security, monitoring and AV deployments where audio clarity and interference rejection matter. Add the Radio Design Labs DB-J2 to your next surveillance or monitoring install for consistent, low-noise inputs — order now to streamline your audio connections.
