Compact 4-Channel Headphone Amplifier

The Pyle PHA40 is a compact control unit designed for studios, rehearsal spaces and small venues that need to feed multiple headphone sets from a single stereo source. Independent rotary volume controls let each listener set their own level without affecting the others, making it practical for tracking sessions, podcast monitoring or silent rehearsals where four people share one mix.

Four 6.35 mm Outputs and One Stereo Input

Four 6.35 mm TRS output jacks provide headroom for four pairs of standard studio headphones, while a single 6.35 mm TRS input accepts the source signal from an interface, mixer or portable player. The unit handles typical line-level signals cleanly, but very low-output sources or high-impedance headphones may need additional gain before the amplifier can drive them to comfortable volumes.

Replaces Y-Splitters and Single-Output Interfaces

The amplifier removes the signal loss and crosstalk that passive Y-splitters introduce when dividing one headphone jack among several listeners. It also upgrades setups that rely on an audio interface with only one headphone output, giving each performer a dedicated level control. The jump is worthwhile whenever more than two people need independent monitoring from the same stereo feed.

Questions about this item

Can I connect my existing 6.35 mm headphones to all four outputs at once?

Yes, the PHA40 provides four 6.35 mm stereo TRS output jacks so you can plug in up to four pairs of headphones simultaneously.

How do I know each channel is passing signal correctly after I power it on?

The front panel power LED lights when the unit is on, and each channel has its own rotary volume control so you can verify audio on every output independently.

Does the box include the power supply and cables I need to start using it?

The package contains the PHA40 amplifier and its power supply; you will need to supply your own 6.35 mm stereo cables for the input and each headphone connection.
