The RDL D-J2 is a passive wall-mounted audio interface designed to connect consumer-level stereo audio sources to professional balanced audio systems. It accepts left and right unbalanced signals through gold-plated RCA inputs and combines them into a balanced line-level output.
Because the D-J2 uses transformer-isolated inputs, it helps reduce hum and interference that can occur when connecting consumer audio equipment to professional sound systems. No external power is required, making the D-J2 a simple solution for permanent commercial audio installations.
Its compact wall-mount design fits standard US single-gang electrical boxes or RDL WB-1U back boxes, making it easy to install in classrooms, conference rooms, offices, restaurants, retail spaces, and other AV environments.

Connect Consumer Audio Equipment to Professional Sound Systems
The RDL D-J2 is useful when a consumer audio source needs to be connected to a professional balanced audio system. The RCA inputs make it easy to connect equipment such as computers, CD players, media players and other devices with unbalanced line-level outputs.
Transformer isolation provides an additional layer of protection against unwanted hum and noise, particularly in installations where consumer and professional audio equipment are connected to different parts of an electrical system.
Typical Applications
The D-J2 works well for:
-
Conference rooms and boardrooms
-
Classrooms and training rooms
-
Office AV systems
-
Restaurants and retail spaces
-
Fitness centers
-
Commercial sound systems
-
Permanent or portable AV installations
Simple Passive Installation
The D-J2 does not require an external power supply. Connect the consumer audio source to the RCA inputs and use the rear terminal block to connect the balanced output to the professional audio system.
Its single-gang mounting format also keeps the installation clean and professional while providing convenient access to the audio input.
Why Choose the RDL D-J2?
The D-J2 is a good choice when you need a simple, passive interface between consumer and professional audio equipment. Rather than adding an active converter or powered device, the D-J2 provides transformer isolation and balanced output in a compact wall-mounted package.
