The Sound Devices 833 Portable Compact Mixer-Recorder is a powerful, versatile tool designed for professional sound engineers who require top-tier audio performance in a compact and portable form factor. This device is particularly well-suited for film, television, and field production, where both reliability and audio quality are paramount.

At the heart of the 833 are 8 input channels, including 6 ultra-low noise, high-performance Kashmir mic/line preamps and 2 additional line-level inputs. These preamps are designed to capture audio with exceptional clarity and detail, making them ideal for recording dialogue, sound effects, and ambient sounds in any production setting. The 833 can simultaneously record up to 12 tracks, making it suitable for complex productions that involve multiple microphones and audio sources.

The 833 is equipped with dual SD card slots, providing redundant recording capabilities and ample storage space. This feature ensures that audio is safely captured and stored, reducing the risk of data loss during critical recordings. The dual slots also allow for longer recording times, as the device can automatically switch to the second card when the first one is full.

In terms of durability, the 833 is built to withstand the rigors of field production. Its compact and rugged design ensures that it can be easily transported and used in various environments, from studio settings to outdoor locations. The device is lightweight yet sturdy, making it a reliable choice for sound professionals on the go.

The 833 offers multiple powering options, including battery, external DC, or USB-C power, ensuring that it can be used in a wide range of situations without worrying about power availability. This flexibility is essential for field production, where access to power sources can be unpredictable.

Advanced audio processing capabilities are integrated directly into the 833, including EQ, limiting, and delay, allowing sound engineers to fine-tune their recordings in real-time. The device also features MixAssist and Dugan Automixing, which are particularly useful in dialogue-heavy environments, providing automatic mixing to maintain consistent levels and reduce background noise.

The 833’s interface is designed for ease of use, with a bright, sunlight-readable LCD screen that makes it easy to operate in any lighting condition. The intuitive layout allows for quick access to essential functions, streamlining the workflow and minimizing the learning curve for new users.

Connectivity is another strong point of the 833, with balanced XLR outputs, USB-A and USB-C ports, and timecode input/output. These features enable seamless integration with other professional audio and video equipment, making the 833 a versatile hub for any production setup.
