Intro
Hello and thank you for buying the MixPre-3! At Sound Devices, we are freaks
about audio. We’ve unleashed our design and engineering team (most of
whom are musicians) and let them create a device that we want to own our-
selves. We think that you’ll nd the unique mix of performance, ease-of-use,
design and build quality to be an invaluable part of your life and creative pas-
sion for many years to come.
The MixPre-3 has been meticulously-engineered to oer extreme exibility and
sound quality, operating in three basic ways:
• 3 mic/line input, 2 channel output mixer with our exclusive Kashmir™ dis-
crete mic preampliers with user-selectable analog limiters and low-cut
lters.
• SD card recording and playback of individual channels and the main mix
simultaneously at 44.1, 48, 96 kHz, 16, 24-bit les.
• 5-in, 2-out USB computer audio interface
The possible uses for the MixPre-3 are virtually unlimited, but a few common
ones might be:
• Paired with a DSLR camera recording high-quality audio for video, complete
with timecode and HDMI record triggering.
• Podcast or music recording using up to three high-quality voice-over micro-
phones (or other sources) interfacing via USB to a computer.
• Stand-alone audio recorder for House-of-Worship, mixing a direct feed from
the PA system with a stereo feed of ambient congregational response, sing-
ing and music from a stereo microphone.
The MixPre-3’s application exibility is augmented by the various powering
options. Whether you wish to power the MixPre-3 from a USB connection, AA
batteries, L-mount batteries or an optional AC wall plug adapter, it’s ready, will-
ing and able to go anywhere, anytime - always handling your audio needs with
grace.
We’ve designed the MixPre-3 to be easy to use for the novice without taking
away truly professional-level features for the seasoned pro user. With that in
mind, the MixPre-3 ships from the factory in Basic mode - this is ideal for less
experienced users and will satisfy the majority of audio applications. If you
want to dive straight into the full array of professional features, we recommend
setting to Advanced mode. See Modes and Presets for more information.
We sincerely hope that you enjoy working with the MixPre-3 as much as we’ve
enjoyed creating it! Please drop us an email at [email protected] and
share your experiences as we’d love to see how the MixPre-3 is furthering your
passion!

Powering
Flexible Powering Options
In designing the MixPre-3, we felt that it was important for it to be able to
operate in a wide array of applications and environments. To support that goal,
power can be supplied from several possible sources. Some possible powering
scenarios are:
• Four AA alkaline or NiMH rechargeable batteries installed in the provided
4-AA battery sled.
• Eight AA alkaline or NiMH rechargeable batteries installed in the optional
8-AA battery sled accessory.
• One or two Sony-type L-mount batteries installed in the optional L-mount
battery sled accessory.
• USB-C to USB-C cable connected to a USB-C host computer or AC wall
adapter.
• USB-A to USB-C cable connected to a USB-A host computer or AC wall
adapter.
• Dual USB-A to USB-C cable (included) connected to a USB-A host computer.
Use this cable option if your computer is unable to provide adequate power
for the MixPre-3 with only one USB-A port.
• Optional MX-CHARGE AC wall adapter to USB-C power supply.
The master power switch for the MixPre-3 is located in the upper right corner of
the left side panel.
Power Switch
To preserve battery power, USB-C power sources take priority over batteries if
both are connected with one exception - if the USB-C power source does not
meet the full power requirements of the MixPre-3, you can choose to power
from battery or continue to power from USB-C. We have designed the MixPre-3
so that even with an under powered USB-C source, you will still be able to use

two of the three channels with 48V phantom mics. The third channel can still
be used with dynamic mics and line, aux, or USB sources. To achieve this we
automatically do the following:
• Dim LCD and LED Brightness
• Disable USB-A port
• Disable HDMI TC port
For protection against accidental loss of power (not something you particularly
want to happen during recording), the MixPre-3 incorporates circuitry to
automatically switch over from USB-C to batteries if the USB-C power source
accidentally gets pulled.

User Presets
Flexibility is the MixPre-3’s M.O. To make it easy for you to use the MixPre-3 in
a wide variety of situations, we created a slick feature where you can store and
recall snapshots of all of the MixPre-3’s settings. There are four internal Preset
slots available. Also, the SD card can store virtually unlimited Presets.
Here are three common examples:
• You might want to use the MixPre-3 as recorder, mixer, and USB audio
interface in a podcasting rig with specic microphones.
• The next day, you need to have the MixPre-3 handle audio duties for you
while you’re shooting video on your DSLR camera.
• On Sunday, you might need to use your trusty MixPre-3 to record worship
services, mixing a direct line from the PA with a stereo microphone feed.
Using Presets, you can optimize settings for each of these scenarios and then
simply save each setup to one of four internal preset locations or to the SD
card. Once saved, simply load the appropriate preset and BOOM! You’re ready
to go in a jiy! We think that you’ll really appreciate this functionality.
To save a Preset:
1. Tap .
2. Tap Presets > Save to Internal 1-4 or SD Card
3. Enter a Preset Name and tap OK.

Inputs
The MixPre-3’s exibility is enhanced by its ability to select various input types
to its mixer channels. Each of the MixPre-3’s channels can be sourced from an
XLR mic/line input, 3.5mm Aux or PiP (Plug in Power) Mic input or from either
of the two USB audio paths from a computer.
Channel Inputs
BASIC MODE -
For quick and easy applications, access the channel’s input settings by
pushing the desired channel’s channel knob. You will see the Channel
screen displayed.
There, you’ll be able to select the channel input source, whether you’d like
to send the audio to the Left, Center or Right in the mix bus and Stereo
out, select Phantom power (for condenser microphones and active DIs),
and select a Low Cut lter. The MixPre-3’s Kashmir mic preampliers have
extreme dynamic range and noise specs as well as analog limiters so it’s
not necessary for you to set any levels other than that of the Channel knob,
which sends the audio to the LR mix record channels and the Stereo Out.
The limiters are present on each channel and the LR mix bus. This means
that peaks that would normally clip other mic preampliers and ruin a mix,
will be handled in just the right way to make sure that your audio is safe
from accidental clipping both on the Stereo Outs and the recorder.
ADVANCED MODE -
For more complex situations requiring individual channel-to-track recording,
soloing, channel linking and extended gain functionality and limiter bypass.

User Guide

Are you working with a stereo source—a keyboard or stereo mic perhaps?
Input that source on Channels 1 and 2 and then push channel 1’s knob
and link those channels in stereo or MS (Mid-Side). You’ll now be able to
control the level of both channels 1 and 2 with the channel 1 knob. The
channel 2 knob will now function as a pan control for the stereo pair.
A Little Bit About Gain
Gain (sometimes referred to as Trim) at the preamplier stage has historically
been a confusing subject for many users. As implemented in the MixPre-3, Gain
sets the level of the incoming signal from the outside world before the signal
gets routed to anything else in the mixer or recorder. In a traditional workow,
it would be typical to connect the input device to a channel and set the Gain
so that the loudest parts of the audio signal just touch the red segments of the
meters. In other mic preamplier designs, this was a very necessary part of
the workow in order to assure the best signal-to-noise performance (minimize
hiss). The Kashmir mic preampliers change the traditional workow paradigm.
Now, precisely setting the Gain is much less critical (in most cases unnecessary)
due to the extremely quiet (lack of hiss) nature of their design. This allows
you to use the MixPre-3 with the condence that even if optimal Gain levels
haven’t been set, your audio will still be handled and recorded with grace. The
extraordinarily low noise oor of the Kashmir mic preampliers allow recorded
tracks to be “normalized” (the process of adding level to a whole recorded track
as to align the loudest peak with near-maximum) in post-processing without
fear of ruining the track due to the added noise that would have been present
in other preamplier designs. Finally, you’re free to capture audio on the y
without worry!
Inputs Menu
The Inputs menu, which is accessed through the Main Menu, allows you to
congure how the Aux/Mic In 3.5mm connector is to be used.
Tap Aux In Mode to select one of the following options:
• Mic: Select this option when the Aux/Mic In is to be used with a plug-in-
power mic.
