Output Switch

Send one signal to one of two destinations, such as headphones or an OBS virtual input.

Switching fades the active destination down over 10 ms, then fades the new destination up over 10 ms. Both destinations are never active together, and an unconnected selected side stays silent.

01 / Understand

The idea, before the settings.

Connect one source to the input, then connect destination A and destination B to the two outputs. The selected destination receives the signal; the other stays silent.

One sourceOutput SwitchHeadphones (A) or OBS cable (B)

Use it in AudioRouter

  1. Connect one source to the Output Switch input.
  2. Connect destination A to headphones and destination B to the virtual cable used by OBS.
  3. Select A for private listening or B to send the signal to OBS. Change the choice while the route is playing.

What success looks like

The selected destination receives audio and the other destination stays silent through the handoff.

If it does not work

If neither destination is audible, check that the selected output port is connected and that its destination is active. An empty side remains silent by design.

Select the node to open Properties. Click its name to rename it. While playing, supported parameter-only edits save after a short pause. For structural edits, use Save when the canvas marks a change. Enabled and Bypass are distinct live controls; see the in-app help for their behavior.

02 / Explore

Make the behavior visible.

The guide audition plays the selected signal once to illustrate that a destination is active. In AudioRouter, A and B are separate graph outputs, such as headphones and an OBS virtual input.

The example repeats until you press Stop, and control changes are heard immediately. The picture shows the tool's shape rather than time; follow the timing in Follow the sound below. This is not a DSP measurement or control for your running AudioRouter session.

03 / Configure

Every control, with a reason.

Try thisUse A for headphones and B for the virtual cable feeding OBS.

Keep in mind Selecting an empty output is silent; the switch never falls back to the other side.

04 / Put it to work

Start with a useful example.

Example 1

Choose between headphones and OBS

  1. Connect your microphone or processed voice to the Output Switch input.
  2. Connect output A to your headphones and output B to the virtual cable selected by OBS.
  3. Select A for private listening or B to send the voice to OBS.
Example 2

Switch while playing

  1. Start the route and confirm the selected destination receives audio.
  2. Choose the other destination in Properties, on the canvas node, or with a Stream Deck toggle action.
  3. Confirm the previous destination becomes silent after the short handoff.

These are starting points. Compare at a comfortable monitoring level and adjust for your own source.

05 / Get unstuck

Small details that matter.

  • Output Switch is not Input Switch: it sends one input to one of two output destinations.
  • Both output ports may feed multiple destinations, but only the selected side is audible.
  • Selecting an unconnected side produces silence instead of falling back.
