The MixPre-3 and MixPre-6 have been designed to provide flexibility in powering. Here are some recommended powering options:

  • 4 x AA batteries (with MX-4AA battery sled) or 8 x AA batteries (with optional MX-8AA battery sled). NiMH rechargeable or Lithium primary AA’s are recommended. Alkaline batteries will provide the shortest run times in most digital electronics.
  • 1 or 2 L-Mount Lithium-Ion batteries with optional MX-LMount battery sled.
  • USB-C port via optional MX-PSU AC power wall adapter. (This accessory was formerly called MX-Charge.)
  • USB-C port via MX-USBY cable and a computer with 2 USB-A ports.
  • USB-C port via a compatible USB-C to USB-C cable and a computer with a USB-C port.
  • External DC power source via adapter with a 4-pin Hirose connector.
    See Cable Techniques' MX-Powersled adapter.
  • Single MDV fitting plate for use with 1 Sony NPF series battery.
    See Hawkwoods' SD-2 adapter.
  • External DC power source via adapter with a 4-pin Hirose connector (10-20v input).
    See Hawkwoods' SD-1 adapter.
  • D-Tap to L-mount adapter for use with the optional MX-LMount battery sled.
    See Hawkwoods' LR-08 adapter.
  • Hirose to L-mount adapter for use with the optional MX-LMount battery sled.
    See Hawkwoods' LR-06 adapter.
  • Anker PowerCore+ 20100 USB-C, Ultra-High Capacity Premium Portable Charger, 20100mAh USB-C battery with USB-C to USB-C cable. See Anker's PowerCore+. For best results, Sound Devices recommends using a USB-C to USB-C cable connection from this battery.

To fully power the MixPre-3 or MixPre-6 from a USB power source not listed above, you will need BOTH of the following:

  1. USB-C power source that is compliant with the USB powering specification and is able to output 7.5W
  2. USB-C cable that incorporates the correct pull-up resistors to identify itself as able to provide 7.5W

If either of these conditions are not met, the MixPre recorder will operate in low power mode: maximum 2x 48v phantom channels, no HDMI, no USB-A. You can still use all of the MixPre’s channels, but only a maximum of 2 can be phantom powered.

NOTE: A USB-A power source used in conjunction with a USB-A to USB-C cable cannot deliver the required 7.5W for full power operation.

Due to the complex nature of the USB-C specifications for powering requirements, Sound Devices cannot make recommendations for USB-C power supplies, batteries or cabling other than our purpose-designed accessories. We have no control over other manufacturer’s products and their (non-)compliance with the published USB-C specifications.
