In Side...
The QH4 includes stereo 1/4” inputs to connect with your mixing console or studio interface. In addition, the amp provides a stereo 1/8” Aux In that’s perfect for playing music via a smartphone or MP3 player.

...And Out
Not only does the QH4 offer four headphone outputs with independent volume control over each channel, but it also features a Master volume control for making overall level adjustments. A stereo 1/8” Aux Out for daisy chaining multiple QH4s together, as well as a master Mute button for silencing all outputs, is also included.

Mono Friendly
Mono audio signals can be connected to the QH4 via the amp’s left 1/4” input jack. Inversely, the QH4’s Mono button can be used to combine stereo channels before being outputted to your headphones to check for any phase issues, mono compatibility or when monitoring tracks that are split left and right.
