RDL Passive Audio Divider-Combiner STD-600, 600 Ohm
Many signals, one clean line.
The RDL STD-600 is a passive 600 ohm audio divider-combiner. It merges several audio sources into a single output, or splits one signal out to several, with RF filtering on every channel.

Too many audio sources, too few inputs.
Mics, stereo feeds and mono lines often need to share one amp input or one signal needs to reach several. A passive divider-combiner handles that without extra powered gear.
Combine, split and filter
One compact module covers the common audio routing jobs in AV installs.
Combine to one output
Merge multiple audio signals into a single output.

ohm impedance
