Sound Devices 633 6-Input Compact Field Mixer


The 633 is a compact, six-input mixer with integrated 10-track recorder featuring PowerSafeâ„¢ technology. It offers six analog inputs and records to SD and CompactFlash memory cards. The 633 is designed for audio professionals requiring go-anywhere portability, without compromising recording or mixing capability.

  • AES input, two-channel AES3 or AES42, four channels of AES output. 
  • Clear, fast, easy to navigate controls and interface; visible in all light conditions, configurable metering and display. 
  • Stereo Linking, MS and L/R. 
  • Input delay selectable on all six inputs plus output bus delay on all six buses. 
  • User-configurable headphone presets plus a headphone favorite mode for quick source selection.
