8-channel Analog Mixer with 24-bit/96kHz Multi-track Recording and Built-in Effects If you really want the SD card recording and expanded USB abilities PLUS Bluetooth, the Onyx is a clean board with nice EQ. If you want to use the built in verb/delay, sound good at gigs without any other gear, stream in stereo, and have per channel compression on hand, then go with the ProFX.

The mixer also allows you to make a stereo recording of your live performance to an SD card (although it does not record the individual tracks).
Compact enough for both home use and the traveling engineer, the Onyx8 combines 24-bit/96kHz multitrack recording with high-gain preamps and a low-noise design to meet the uncompromising demands of professionals everywhere. Top it off with a full-color display and easy navigation, and you get a formidable analog mixer capable of capturing audio with impeccable quality.
