Key Features
The Lambden Audio HPA4 4 Channel Headphone Amp is suited to recording, rehearsal, and shared listening environments.
Designed to distribute a single stereo source to up to four pairs of headphones, the HPA4 makes it easy for multiple users to monitor the same audio signal simultaneously. Each output features its own dedicated volume control, allowing performers, engineers, and listeners to set comfortable listening levels independently without affecting other users.
A stereo 1/4" TRS input provides straightforward connection to mixers, audio interfaces, headphone outputs, and other audio sources. The compact enclosure fits neatly into desktop and studio setups, while the black finish and protective side panels help it blend in with surrounding equipment. Whether you're tracking musicians, practising with others, or sharing audio between multiple listeners, the HPA4 provides a practical and easy-to-use monitoring solution.

The HPA4 allows up to four pairs of headphones to be connected to a single stereo audio source. This makes it particularly useful for recording sessions, rehearsals, podcast production, and collaborative listening environments where multiple people need to hear the same signal. By distributing audio from one source, it helps simplify monitoring setups without requiring multiple headphone outputs on your mixer or interface.
Each of the four headphone outputs includes its own dedicated volume control, allowing users to adjust listening levels to suit their individual preferences. This is especially useful in recording and rehearsal situations where different performers may require different monitoring volumes. Because each output operates independently, one user's adjustments won't affect anyone else's listening experience.
A stereo 1/4" TRS input makes it easy to connect the HPA4 to mixers, audio interfaces, playback devices, and other audio equipment. Dedicated power and status indicators keep operation straightforward, while the onboard power switch provides quick control when setting up or shutting down your system. The uncomplicated layout helps keep workflows efficient whether you're in the studio or at home.
The HPA4's compact footprint makes it easy to position alongside existing audio equipment without taking up excessive desk space. Its black finish blends neatly into studio and rehearsal environments, while protective side panels help guard against knocks during transport and regular handling. Designed for practical everyday use, it's a straightforward solution for anyone needing multiple independent headphone feeds from a single source.
Lambden Audio delivers professional-grade audio electronics designed for both studio recording and live performance. Used by musicians, engineers and producers, Lambden Audio products are built to perform reliably in demanding environments.
