Radio Design Labs DB-J3 Ic Line Input Assembly Xlr Rca

Product Description

The RADIO DESIGN LABS DB-J3 is an IC line input assembly designed to accept both XLR and RCA signal inputs in professional and commercial audio system installations. This unit serves as an input interface module, allowing balanced XLR connections and unbalanced RCA connections to feed downstream signal processing or distribution equipment. It is typically installed by audio-visual technicians, systems integrators, and low-voltage contractors working in commercial AV, broadcast, or installed sound environments. The DB-J3 is sold as an individual assembly unit and provides a compact, fixed-input solution for structured audio wiring applications.

The DB-J3 is suited for commercial and professional installed-sound applications where both balanced and unbalanced source inputs must be accommodated at a single input point. Typical installation scenarios include conference rooms, houses of worship, performance venues, and broadcast facilities where mic-level or line-level sources originate from a mix of consumer RCA and professional XLR connectors. It is designed for permanent installation as part of a structured AV system rather than portable use.

Key Features

• Accepts both XLR balanced and RCA unbalanced line-level inputs

Installation Notes

Installation of the DB-J3 should be performed by a qualified low-voltage technician or licensed AV systems integrator. Power down or de-energize the signal chain and any connected equipment before making input connections. Follow applicable low-voltage wiring codes and the system manufacturer's routing guidelines when integrating this assembly into a permanent installation. Consult the product manual for pinout and mounting details before wiring.
