RDL DS-CIJ3D – Stereo Audio Input Module with Transformer-Isolated Balanced Output

RDL DS-CIJ3D is a professional stereo audio input module designed to convert unbalanced consumer line-level signals into balanced (or unbalanced) stereo outputs. It is ideal for AV installations requiring clean signal integration from consumer sources into professional systems.

The front panel includes two gold-plated RCA jacks (left/right) and one stereo 3.5 mm mini-jack. Input signals can be connected to either the RCA or mini-jack input. Each channel is transformer-isolated to reject hum and noise, and routed to a rear-panel detachable terminal block as stereo balanced or unbalanced outputs.

The module is designed for use with equipment featuring input impedance of 10 kΩ or higher. With passive operation and compact design, the DS-CIJ3D is a reliable solution for stereo audio integration in commercial AV environments.

Functionality

• Stereo unbalanced-to-balanced signal conversion
• Transformer isolation for hum and noise rejection
• Supports consumer audio sources (RCA, mini-jack)
• Passive operation – no power required
• Independent left/right channel processing

Features

• Device type: passive stereo audio input module
• Inputs: 2 x RCA (L/R), 1 x stereo 3.5 mm mini-jack
• Outputs: stereo balanced or unbalanced (terminal block)
• Isolation: audio transformers
• Signal type: unbalanced line-level
• Output impedance: suitable for ≥10 kΩ inputs
• Mounting: panel-mount (wall or desktop)

RDL DS-CIJ3D is a compact and effective solution for integrating stereo consumer audio sources into professional AV systems with transformer-isolated balanced outputs.
