RDL DS-J3 – Wall-Mounted Mic/Line Audio Input Panel with Transformer-Isolated Output

RDL DS-J3 is a professional wall-mounted audio input panel designed for AV installations requiring both microphone and consumer line-level inputs. It features a front-panel female XLR connector and two RCA jacks, offering flexible connectivity in a single module.

The XLR input is wired directly to a rear-panel barrier block, while the RCA inputs are summed to mono and converted to a balanced output via audio transformers, providing hum rejection and galvanic isolation. The line-level output is available on a detachable terminal block and is suitable for equipment with an input impedance of 10 kΩ or higher.

The DS-J3 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 ideal for conference rooms, sound systems, and multimedia installations.

Functionality

• XLR microphone input and RCA line-level inputs
• Stereo-to-mono summing for line inputs
• Unbalanced-to-balanced conversion via transformers
• Transformer isolation for hum and noise rejection
• Passive operation – no power required

Features

• Device type: mic/line audio input panel
• Inputs: 1 x female XLR (mic), 2 x RCA (L/R – line)
• Output: mono balanced (terminal block)
• Isolation: audio transformers (line inputs)
• Signal types: mic-level (XLR), unbalanced line-level (RCA)
• Output impedance: suitable for ≥10 kΩ inputs
• Mounting: wall or furniture (compatible with RDL WB-1U)

RDL DS-J3 is a versatile and reliable input panel for integrating both microphone and consumer audio sources into professional AV systems with transformer-isolated balanced output.
