4 channel headphone amplifier

Introducing Nowsonic Ampix

For most projects involving more than one person, a separately controllable headphone monitoring function is needed for each participant.

The Nowsonic Ampix headphone amplifier can be used in the studio, for band rehearsals, and even for home entertainment or hi-fi systems. For any situation requiring amplification and individual volume control for up to four headsets, either with line level or headphone amplifier signals, in stereo or mono, the Nowsonic Ampix is the ideal solution.

“Unadulterated transmission without ambient noise, not too smooth potis and different connection options on the back, what more could you want ? I use the device in the studio and also my friends are “enthusiastic”. BUY RECOMMENDATION!”

“Very good workmanship, sound quality and handling.”

“The Nowsonic separates all four channels cleanly and amplifies them where our 50Ohm headphones reaches its limit when the controls are not even half turned up. The workmanship inside and outside is good for the price.”
