RDL STD-10K Passive Audio Divider/Combiner

The STD-10K from RDL is a Passive Audio Divider/Combiner.

Each STD module is a resistive branching network with RF filtering on each of the four channels. Any channel, A through D, may be either an input or an output. This permits combining stereo signals into mono inputs, splitting mono signals to multiple inputs, and even combining microphones with output shorting switches into a single amplifier input. The STD modules are available in 150Ω, 600Ω, and 10 kΩ models. All inputs and outputs are balanced.
