STD-150

RDL STD-150 - Passive Audio Divider/Combiner (150Ω)

The RDL STD-150 is a compact, passive audio module designed for splitting and combining balanced audio signals in 150Ω systems. It features a resistive branching network with RF filtering on each of its four channels, ensuring clean signal transmission even in interference-prone environments.

Each channel (A-D) can be configured as either an input or output, offering maximum flexibility. Use cases include combining stereo signals to mono, feeding mono signals to stereo inputs, distributing one signal to multiple destinations, or combining multiple microphones (even with shorting switches) into a single amplifier input.

Its STICK-ON® housing allows discreet mounting behind panels, inside racks, or under surfaces, making it ideal for AV, broadcast, and sound reinforcement installations.
