Sound Devices is proud to introduce the new 633 Six Input / Ten Track Field Production Mixer. The 633 is a compact, six-input mixer with 10-track integrated recorder featuring our new PowerSafe technology.

The 633 records 24-bit at 48kHz of all ten tracks (six tracks at either 94 kHz or 192 kHz.)


The 633 is Powered by a unique Quad Power supply with PowerSafe technology, the unit is operational from any of four power sources.

Sources can include external DC (12-18 V), two removable 7.2 V L-type lithium ion cells, and six internal AA batteries. When all power sources are removed or depleted, the unit’s PowerSafe circuitry is activated. PowerSafe keeps the 633 operating for up to 10 seconds and ensures that all file operations are fully closed and the unit gracefully shuts down or gives time to connect a fresh power source.
