Generally, no. Most multi-channel headphone amplifiers are active electronic devices designed for one-way signal flow; they cannot sum multiple inputs into one output in reverse without damaging the unit or causing severe signal distortion.

What to do
  1. 1.Check if your headphone amp is 'passive' (no power cord); if so, it can technically pass signal backwards, but with significant signal loss and impedance issues.
  2. 2.Identify the inputs and outputs; most headphone amps use active circuitry (OP-AMPs) that only allows signal to flow from the input stage to the output stage.
  3. 3.Connect your sources to a dedicated Line Mixer instead of the headphone amp to combine them into a single monitor feed.
  4. 4.If you are trying to 'mult' a signal (one source to many destinations), use a passive splitter or a distribution amplifier instead.
Common mistakes
  • ×Active circuits (found in almost all powered headphone amps) do not allow electricity to flow backwards through the amplifier stage.
  • ×Attempting to 'back-feed' an output can cause electronic components to overheat or short circuit.
  • ×Using a 'Y-cable' to combine signals without a mixer can lead to impedance mismatching and permanent damage to your audio interface's output stage.
Pro tip

If you need to combine signals on a budget, look for a 'passive summer' or a small 4-channel line mixer like the Mackie Mix5 or ART MacroMix, which are designed specifically for this purpose.
