Samson Launches the QH4 Four-Channel Headphone Amplifier at NAMM 2017

	Samson's QH4 four-channel headphone amplifier

Samson, a provider of professional live and studio audio products, announces the QH4 4-Channel Headphone Amplifier. The QH4 is designed to distribute audio to up to four individual headphones, each with its own volume control making it perfect for tracking multiple performers in a studio, podcast recording, or recreational music listening. Its compact design makes the QH4 ideal for use with any studio or desktop workstation, as well as with laptops or smartphones when recording on the go. Samson will exhibit at NAMM 2017 in booth 6900, Hall A, January 19 - 22, in Anaheim, California.

Samson's QH4 includes stereo 1/4" inputs to connect with a mixing console or studio interface, and a stereo 1/8" aux in for playing music via a smartphone or MP3 player. Individual headphone outputs allow users to connect up to four sets of headphones, each with its own independent channel volume control, as well as a master volume control for overall level adjustments. Also provided is a stereo 1/8" aux out for daisy chaining multiple QH4s together and a master mute button for silencing all outputs. Stereo channels may be combined using the QH4's key feature, the mono button, before audio is sent to headphones, allowing listeners to check for phase issues, mono compatibility, or when monitoring tracks that are split left and right. The mono button also allows the user to take a split left and right feed from a stereo interview and send both tracks to each side of their headphones, ideal for quickly monitoring a split track podcast or recording. Samson's QH4 is available now.
