AV-DC4

RDL AV-DC4 - 4-Channel Balanced Audio Splitter/Combiner with Galvanic Isolation

The AV-DC4 is a professional-grade module for splitting and combining balanced line-level audio signals in AV environments. It provides galvanic isolation and balanced signal transmission, eliminating ground loops and interference. With four independent channels, the AV-DC4 is ideal for studio, installation, and mobile applications.

Each channel can function as an input or output depending on the XLR connector used - female for input, male for output. High-quality audio transformers ensure galvanic isolation and minimal distortion. Each channel includes a GND LIFT switch to disconnect signal ground individually, preventing ground loop noise.

AV-DC4 offers flexible signal routing for mono and stereo applications, including stereo-to-mono summing, mono signal distribution to multiple destinations, or a combination of both within a single unit.
