Samson QH4

The Samson QH4 is a sleek beautiful designed 4-Channel Headphone Amp that features two balanced 1/4" inputs to connect with your mixer or recording interface, as well as a stereo 1/8" Aux input that's perfect for playing music via your smartphone or another line level device. In addition to the four stereo 1/4" headphone outputs, the QH4 provides a 1/8" Aux Out that can be used to daisy chain multiple QH4s together.

The four independent high-power amplifier channels deliver clean, crisp audio to up to four sets of headphones, operating between 16–600Ω. And power does not diminish even when all four channels are being used. Engineered with an ultra-low noise floor and wide dynamic range, the QH4 is a tremendous value compared to other headphone amplifiers on the market. Also, the QH4's Master volume control and Mute switch make controlling the overall level of your headphones a breeze.
