PH400 4-Channel Stereo/Mono Portable Headphone Amplifier

The PH400 4-Channel Stereo/Mono Portable Headphone Amplifier is a compact headphone distribution amplifier designed to distribute a single stereo audio source to multiple headphones, allowing each user to adjust their listening level independently.

The device features a total of 4 independent headphone channels. Each channel offers both 3.5mm and 6.35mm headphone connections, providing a total of 8 physical headphone outputs (four 3.5mm and four 6.35mm). These two socket types facilitate the connection of headphones with different connectors without the need for adapters.

Each channel has its own VOLUME potentiometer and MUTE button. This allows four users listening to the same audio source to adjust their volume levels independently and mute only their own channel when necessary.

The PH400 also features a MONO/STEREO selection function. When using a stereo source, left and right channel information can be preserved;

For mono sources, the MONO mode can be selected to distribute the signal appropriately to the headphone outputs.
