Whether you’re editing videos, recording in a studio or just want to listen to some music with friends the Samson QH4 Four-Channel Headphone Amplifier has got you covered. Designed to distribute audio to four individual sets of headphones, the pocket sized QH4 is the perfect on-the-go and desktop accessory.  Ideal for your home or project studio, the QH4 lets you connect up to four headphones at the same time via ¼” inputs located at the front of the unit. Every channel has a separate level control so each listener can dial in their own volume setting as the signal comes through. The four individual amplifier channels offer volume control, clean crisp audio for up to four sets of headphones at once. For overall control of your sound, the QH4 is built with a master control knob and a master output mute control. Engineered to give you the ultimate listening environment, this small but feisty tool has an ultra-low noise floor and a wide dynamic range.

Volume Boost

In addition to distributing your mix to different listeners, the QH4’s four independent high power amplifiers boost the dynamic range of the signal resulting in ultra clean, smooth, high gain audio. The systems circuitry is designed to provide an ultra low noise floor so your mix comes through uncolored. A master volume control and mute button allow you to quickly apply changes for all listeners.

Flexible I/O

Along with the four well engineered headphone inputs, the Samson QH4 Headphone Amplifier is made with enough connections to integrate into any recording, editing, or leisure situation. Featuring two ¼” inputs, a stereo 1/8” aux Input, and a 1/8” aux output you can connect this device to a mixer, recording interface, your smartphone, or other QH4s!

Check your Phase

Upon further examination of the QH4 you will also notice a Mono Button. Engaging the Mono setting allows you to check how your mix will sound on Mono music playback systems. This is perfect for double checking the phase of your recordings. Dual ¼” and 3.5mm stereo inputs provide maximum capability with a variety of music sources.

Mono Ready

When recording and editing music, videos, podcasts and more, you should always ensure that your mix can be played in both stereo and mono. The QH4 features a global Mono button, which allows you to quickly check the mono compatibility of your tracks. The global mono button also allows the user to split a right and left feed from a stereo interview, to hear each track in one side of the headphones, making for quick monitoring of a podcast or any recording with split tracks.

Clean. Did exactly what I needed it to do.



Great headphone amp


Works well! I used this for a recording session with no issues. The quality seems good and had no issues. If you have multiple different headphones remember that you'll have to adjust the volume on each brand separately due to the impedance variations.



Awesome Device


Great Service



Perfect fit for my small home studio


This fits my small home studio and the layout of my studio. I needed the mic to be far from my computer and I use this to do exactly that. #sweepstake

Perfect for my style of recording (small home studio)


I think it was the perfect fit for me. I am recording my friends in my basement, and we are getting better and better but we re not professionals. I needed the amplifier so that the mic can be placed in another room and it worked out perfectly. For the price, I think this is a great option.
