RDL D-J2 Line Input Assembly RCA Jacks, Terminal Block

Deliver clean, dependable audio from consumer sources into professional monitoring and security systems. The Radio Design Labs D-J2 line input assembly accepts RCA/phono inputs and transforms them into a balanced, line-level output ideal for surveillance, monitoring and commercial AV installations. Gold-plated RCA jacks ensure a low-loss connection while internal audio transformers provide hum rejection and galvanic isolation—preserving signal quality even over long cables. The balanced output is presented on a rear terminal block for seamless connection to 10 kΩ or higher input devices. Housed in a clearly labeled metal enclosure and measuring a compact 4.1" x 1.7" x 2.2", the D-J2 mounts into standard US single-gang boxes or RDL back boxes for clean, professional installs. Designed by Radio Design Labs and built in the USA, this faceplate module simplifies integration of consumer-level audio into pro systems used for security, surveillance and remote monitoring. Add the D-J2 to your next project to reduce noise, improve audio reliability, and streamline installation.
