Accompany yourself or play with a friend

The MixPre-3M is the ideal tool for solo musicians and duos. With three crystal-clear Kashmir preamps, you can record vocals and acoustic guitar, mic up your piano, or jam with another musician. Even a quiet singer or instrument will sound pristine with the Kashmir’s ultra-low noise floor. Add built-in effects like reverb or vocal air to spruce up your audio and add confidence to your performance. Jamming by yourself? Create layers of tracks and use them as backing tracks live or at home for writing or practicing. Capturing your song ideas has never been easier.

Record anytime, anywhere

The MixPre-3M is both a multitrack recorder/mixer and a USB interface, so you can record at home with your computer and also at band practice – all you need is a compatible SD card. Mix, overdub, and add effects in the MixPre-3M itself or export the tracks and work on them in your DAW. You can power the MixPre-3M with your computer, wall power, or record in the middle of nowhere with AA or Sony L-mount batteries. The choice is yours.

Expand your studio, keep your MixPre

The MixPre-3M is a pro-level recorder at the heart of your rig. With the clean, boutique Kashmir preamps developed by Sound Devices, the industry leader for audio in film and TV, you won’t have to replace your MixPre as you expand your studio down the road.

Installation Instructions

Please read and follow the steps below carefully. You may want to print them before upgrading firmware.

Sound Devices recommends saving a setup file prior to loading new firmware.

Prepare to Update

  1. Download the MixPre firmware file MixPre_ 3.03.zip using the link above.
    From the zip archive, extract the file within named MixPre_ 3.03.prg file. Copy this .prg file to the root level (not within a folder) of an SD memory card that has already been formatted by the MixPre recorder.
  2. Power the MixPre via USB-C to external DC power or via "fully charged" batteries. Do not perform the update with low batteries or unstable power sources.
  3. Insert the SD card with the .prg file.
  4. Power on the MixPre.
  5. Navigate to System > Update Firmware and follow the on-screen instructions.
  6. When the update is complete the recorder will power cycle itself. The version number MixPre_ 3.03 will be displayed briefly on the splash screen while booting up. A message box appears "Firmware updated successfully Version:MixPre_ 3.03". Tap "OK". Please note any changes or additions to the main Menu (if applicable). Consult product documentation for details.
