3.5 mm A/B Audio Switcher

The AVer M201 is a passive, bidirectional audio selector that routes stereo signals through 3.5 mm jacks. It serves users who need to toggle between two source devices or send one source to two different outputs without unplugging cables. The aluminium chassis measures 44 by 50 by 23 millimetres and weighs 50 grams.

Plug-and-play with independent grounds

Installation requires only inserting the 3.5 mm plugs into the labelled ports and moving the selector knob. No drivers, software or external power are needed because the unit is entirely passive. The independent ground design switches the ground connection alongside the signal, preventing the hum or noise that commonly occurs when two sources share a common ground.

Transparent signal path under continuous use

Because the switcher contains no active electronics, it adds no latency, distortion or colouration regardless of how long it remains in one position. The mechanical contacts maintain a clean path for both TRS and TRRS connections, so microphone functionality on headsets persists during extended sessions. Performance stays consistent whether switching once a day or dozens of times per hour.

Questions about this item

How do I confirm the M201 is routing audio correctly after I connect my sources?

Play audio from the first connected source and verify sound at the output, then toggle the A/B selector to the second source and confirm the audio switches without noise.

What cables or adapters must I provide beyond the M201 unit itself?

The switcher includes only the aluminium chassis with 3.5 mm jacks; you must supply all 3.5 mm TRS or TRRS cables for your sources and outputs.

Should I choose the 2 IN 1 OUT or 1 IN 2 OUT wiring for my laptop and headphones?

Wire it 1 IN 2 OUT when one laptop feeds two headphone sets, or 2 IN 1 OUT when two sources share one speaker; the same M201 handles either topology.
