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.

Rated 5 out of 5 by from Stepping Up The Audio A step-up in function, and form. We produce regular videos and high quality audio is essential. We upgraded to the 633 and was not disappointed. High quality pre-amps, choice of inputs and outputs, and the auto-mix for interview recordings makes a big difference. Well built, professional grade and worth the price. Here you do get what you pay for... totally recommended.

Rated 4 out of 5 by from Consistent Quality from Sound Devices Another great design from Sound Devices, who quite obviously listened to the feedback they were getting from the release of their other flagship recorder, the SD 664. Previous to the 633 I had a 664 which was brilliant, but large and bulky which didn't do my back any good when lugging it around on shoots. The 633 is compact, has an intelligent, well-thought out design and makes my life a lot easier when carrying it around. Plus, my mind exploded when I realised the faders for channels 4 - 7 POP OUT just like the trim pots.
Coming from the 12-tracks of the 664, I often feel a little restricted by the reduced 6 ISO tracks however, but seeing as most of the jobs I seem to get are just two rads and a boom, I'm sure those insecurities will fade over time. I've also heard the 633 has a bit of a reputation for crashing...haven't had it happen to me yet, but I'll be sure to update when/if it does.

Rated 5 out of 5 by from Great product This is a great little unit that I feel like I can rely on. Good battery/powering options, can record at high sample rates. Perfect for small location sound jobs.

I'd like to see a product somewhere between this and the 664 that has at least 4 mic preamps in a proper mixer package, and iso track recording up to at least 96kHz in the future. You can start to look at 788T and add-on options for features, but the price jump is quite large. Overall, I can't complain at all about the quality and features of this little unit for the price, hence 5 stars.
