The four independent high-power amplifier channels deliver clean, crisp audio to up to four sets of headphones, operating between 16–600O. 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.

Check Your Phase
Before bouncing your mix, you should always check to ensure that it s compatible with mono speaker systems. The QH4 features a global Mono button, which allows you to quickly check the mono compatibility of your tracks. If you notice that some of your audio is missing, you should check the phase of your recordings. This feature also allows you to take a split left and right feed from a stereo interview and send both tracks to each side of your headphones. This is great for quickly monitoring a podcast or recording with split tracks.
