RDL DB-J2 - Wall-Mounted Line-Level Audio Input Panel with Transformer Isolation

RDL DB-J2 is a professional wall-mounted audio input panel designed for integrating unbalanced consumer line-level sources into balanced audio systems. It provides transformer isolation and hum rejection, making it ideal for AV installations requiring clean signal conversion.

The front panel features two gold-plated RCA jacks for stereo or mono input. Left and right channels are summed to mono and converted to a balanced line-level output via audio transformers. The output is available on a rear-panel terminal block and is suitable for equipment with an input impedance of 10 kΩ or higher.

The DB-J2 fits standard electrical boxes (e.g., RDL WB-1U) or can be mounted directly into AV furniture. With passive operation and compact design, it is a practical solution for professional AV and sound reinforcement systems.
