I have no DAW handy, and I recorded my tracks in 32-bit float mode too hot. Can I adjust the file’s gain after recording?

Yes. The MixPre II has a very powerful feature called Remix/Rerecord which allows you to simultaneously play back a file and record a new L/R mix while adjusting the gains with the fader knobs.

How does the MixPre II achieve such high dynamic range in 32-bit float mode?

The MixPre II recorders feature Sound Devices’ own patented topology of multiple analog-to-digital converters. These converters appear in the circuitry after the Kashmir microphone preamplifier stage. They enable the recording of very-low distortion, ultra-high dynamic range audio. The MixPre II’s A-to-D’s can resolve more than 142 dB of dynamic range. Together with their Kashmir microphone preamplifiers and 32-bit float files, the MixPre II captures audio that is limited only by the capabilities of the microphone.

How do the MixPre II mic preamps compare to the original MixPre series?

The new MixPre II models, like the original MixPre-3, MixPre-6, and MixPre-10T recorders, offer the same discrete class-A Kashmir microphone preamplifiers with an exceptionally low noise-floor regardless of the gain setting. The recorder’s input gain, whether set high or very low, produce excellent results.

Any improvements to the headphone knob compared to the original MixPre models?

The MixPre II comes with a handy headphone knob “tire”. This allows for easy fingertip operation. Conveniently, this tire is removable in case large connectors or cables get in the way. 

Will the MixPre II support my control surface? Wingman?

Yes. The MixPre II supports the same control surfaces and Wingman functionality as the previous MixPre models.

Is Ambisonics supported? 

Yes. An optional Ambisonics Plugin is available for the MixPre-6 II and MixPre-10 II on the Sound Devices plugin store. 16- and 24-bit operation is supported. 

Is binaural monitoring available when using Ambisonics?

Yes. Binaural monitoring is available (up to 48 kHz) for record and monitoring. 

Is there a multitracking feature on the MixPre II for musicians? 

All MixPre II models support the Musician Plugin, so you can easily create a song using your MixPre II as a standalone recorder featuring over-dub, reverb, metronome, and more. Visit the Sound Devices plugin store for more information.

What are my limiter options? 

In 16- or 24-bit operation, the MixPre II offers analog/digital limiters similar to the original MixPre recorders. These limiters have been improved to give control over ratio, release, and threshold. In 32-bit float mode, the multi-stage A-to-D converters are active to capture the full dynamic range of the incoming signal; no limiters are needed. 

Is timecode accuracy maintained while powered down?

All of the MixPre II Series now include a full-featured internal timecode generator and are accurate to better than 0.2 ppm (0.5 frames per 24 hours). When the unit is off, the MixPre II Series maintains accurate timecode for up to four hours, even without batteries or external power.

What’s in the box?

  • AC wall adapter
  • USB-C to USB-C cable
  • MX-4AA Battery Sled (MixPre-3 II and MixPre-6 II)
  • MX-8AA Battery Sled (MixPre-10 II)
  • Anti rotation pin 
  • Allen wrench
  • Headphone tire.

What are my media options?

We recommend our SAM-32SD card. Additionally, most reputable manufacturers’ cards (such as SanDisk or Delkin) that meet or exceed class 10 speeds are acceptable. 

Can I upgrade my original series MixPre?

Due to the hardware differences, an original MixPre cannot be updated to the MixPre II.

Does Sound Devices offer a trade-in program?

The MixPre II Series is available for sale only through our resellers. We do not offer trade-ins for the original MixPre Series.
