Recorder SOUND DEVICES 633

The Sound Devices 633 is a compact, six-input mixer with integrated 10-track recorder featuring PowerSafe 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.

The 633 offers three high-bandwidth mic/line inputs on XLR connectors, complete with phantom power, highpass filter, input limiter and variable pan. Three additional line-level inputs on TA3 (mini-XLR) connectors offer flexibility for more complex productions. All inputs are assignable to its six output buses, Left/Right plus Aux 1/2/3/4.

All six inputs plus output buses Left/Right and Aux 1/2 can be recorded to individual tracks. The Sound Devices 633 offers 10-track 24-bit, 48 kHz uncompressed WAV recording (96 kHz and 192 kHz sampling up to six tracks) to SD and CompactFlash memory cards. The two cards can be set independently, recording either identical material for a real-time backup, or combinations of WAV and MP3 files.

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. The 633 automatically switches from one power supply to the next when power is exhausted or removed. With its combination of power sources, the Sound Devices 633 can operate for a full production day on batteries alone.

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
