HA400 Headphone Amplifier - Amplifier or Adapter Set

Let several listeners follow the same audio while choosing their own volume. The HA400 amplifier options provide four headphone outputs from one source, making a shared listening or monitoring setup easier to arrange.

✅ Share one feed with four listeners - The amplifier distributes a common input across four headphone output channels.

✅ Adjust volume for each listener - Each channel has its own level control for individual listening preferences.

✅ Keep the setup within reach - The compact amplifier fits alongside a small recording or rehearsal station.

Give Every Listener a Separate Level Control

A rehearsal playback or recording check can involve several people listening to the same source. Separate headphone outputs let everyone follow it together, while individual level controls avoid forcing a single volume setting on all listeners.

Choose an amplifier option with the correct power adapter for your location. The option labelled '5PCS 6.35mm to 3.5mm' is an adapter-only selection and does not include the amplifier; the device features apply to the amplifier options.
