How to use

Connect the mixer to a computer via USB, then plug your microphones and line-level sources into the XLR and 3.5 mm inputs. Adjust each channel’s fader to set relative levels, and use the dedicated line and headphone volume knobs to set output monitoring levels. Select the HyperX Audio Mixer as the input device in your recording or streaming software to capture 24-bit/96 kHz audio.

Recommendations

For consistent results, start with all channel gains low, then raise each fader while monitoring through headphones. Use an XLR microphone such as the HyperX ProCast for best sound quality, and ensure your software sample rate matches 96 kHz when high-resolution capture is required.
