Anytime, Anywhere Audio
The MixPre-3 is a lightweight, high-resolution audio recorder with integrated USB audio streaming and offers professional sound quality combined with durability that is suitable for musicians, sound designers, podcasters, and videographers.
Solid Audio Quality
Featuring handcrafted, high-performance, ultra-low-noise, discrete, Class-A Kashmir microphone preamps, the MixPre-3 has a -130 dBV noise floor, analog limiters, and 32-bit A-to-D converters. These features ensure quality audio recordings.
USB and Recording
The MixPre-3 makes for a versatile USB audio interface, offering the unique ability to record audio to an SD card while simultaneously streaming multiple channels of audio via USB. It is handy for interviews, podcasts, or simply as a backup recorder to your computer, and the MixPre-3 can be used for Skype or Facetime interviews and to record audio for podcasts or video blogs.
Pocket-Sized, Unintimidating Design
The small stature and design of the MixPre-3 will fit most production environments. It features a touchscreen for simple and intuitive operation and a sunlight-readable color LCD for convenient navigation. Constructed with a die-cast aluminum chassis, it is both lightweight and robust. The MixPre-3 is compact, so much so that it can fit in your pocket, and it's ideal for jobs on the run.
The MixPre-3 bridges the gap between sound engineers, musicians, and YouTubers with user-friendly navigation featuring Basic and Advanced modes. It is designed to allow a user to start recording right out of the box.
Advanced Mixing Capabilities
With a full-featured mixer, the MixPre-3 offers ergonomic gain-control knobs for fast and accurate mixing. Other key features include pan and soloing plus easy-to-see ring LED metering per channel. It also includes a 3.5mm jack for headphone monitoring with user-programmable presets from its wide-bandwidth headphone amp.
A Videographer's Dream
As an added benefit to DSLR users, the MixPre-3 has a retractable 1/4"-20 mounting thread, making it a good match for a wide variety of cameras. This design allows for solid, low-profile tripod/camera mounting; because the male and female 1/4"-20 threads are captive, they cannot be lost and are always available. Capable cameras can feed timecode to the device over its HDMI input, which provides synchronization of sound and video. Timecode can also be fed into the unit's 3.5mm input from an external TC generator. The MixPre-3's HDMI input can also receive "record triggers" from popular cameras, which automatically start and stop recording via the camera's record button.
Flexible Powering Options
The MixPre-3 has multiple powering options. It can receive power from AA batteries in a convenient detachable sled of either four or eight cells. Also available is a sled that offers powering from up to two hot-swappable, Sony L-Mount lithium-ion batteries. Additionally, the entire recorder can be powered from a laptop's USB Type-C or USB Type-A connectors, offering convenient connection and powering with just one cable. For applications where AC power is available, Sound Devices offers an optional AC adapter as well.
Wireless Remote Control
Sound Devices Wingman, which is a free download from Apple's App Store, is a wireless interface that gives users touchscreen access to monitor meters, start and stop recordings, and edit filenames and metadata on the MixPre-3 directly from any mobile device running iOS 8.0 or later.
