QH4
-4-Channel Headphone Amplifier
In Side... And Out
The QH4 has two balanced 1/4-inch inputs for connecting to your mixer or recording interface, and a stereo 1/8-inch auxiliary input that's perfect for playing music from your smartphone or other line-level device. In addition to the four stereo 1/4" headphone outputs, the QH4 has a 1/8" aux output that can be used to daisy-chain multiple QH4s.
More Inputs, More Power, More Control
The four independent high-power amplifier channels deliver clean, crisp audio to up to four sets of headphones, operating from 16 to 600 ohms. And the performance never degrades, even when all four channels are in use. With an ultra-low noise floor and wide dynamic range, the QH4 is a tremendous value compared to other headphone amplifiers on the market. In addition, the QH4's master volume control and mute switch make it easy to control the overall level of your headphones.
Check Your Phase
Before you bounce your mix, it's a good idea to make sure it's compatible with mono speaker systems. The QH4 has a Global Mono button that allows you to quickly check the mono compatibility of your tracks. If you find that some of your audio is missing, 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.
Whether you're tracking multiple artists in the studio, recording a podcast, watching a video with friends or just kicking back with a few tunes, the QH4 delivers great sound at an amazing value.
