The 633 has firmly established itself as a classic mixer and recorder. Perfect for run and gun shoots, but with the versatility for more, the 633 combines Sound Device’s excellent pre-amps, a rugged exterior, and a smooth interface. It’s no wonder it’s a go to product for many recordists. The Sound Devices 633 has 3 mic level inputs and 3 line level inputs, as well as 3 mix buses. You can also record internally onto either a CF or SD card simultaneously for redundancy. Supplied with an Orca mixer bag, CF and SD card, and Sony backup batteries. Best used with our Hawkwoods NP70 battery option for all-day power.
