MOMIX is a mixer for portable device recording and live streaming. You can connect microphones, guitars, keyboards, electronic drum sets, and more. It features two stereo line-level input jacks for multimedia equipment.
Simply set the instrument and vocal volumes on the MOMIX, then connect headphones or an amplifier for monitoring. When composing songs or using a guitar effects pedal app, turn on GarageBand or similar software and use it with MOMIX.
MOMIX is also suitable for singing and live streaming. Turn on the MOMIX's CENTER CANCEL function to reduce the original vocal volume of the playback music, making your voice more prominent.
For audio-to-video synchronization, MOMIX can output stereo audio to your smartphone in real time. It is ideal for songwriting, livestreaming instrumental performances or karaoke, recording musical performances, and making music production and live performance more convenient and versatile.
