Sound Devices Introduces 633 Mixer
Features four-way power supply
November 15, 2013
REEDSBURG, WIS. — Sound Devices has rolled out the 633, a six-input mixer with integrated 10-track recorder. It includes Sound Devices’ proprietary PowerSafe technology and a four-way power supply for maximum operational runtime. The 633 has a full complement of I/O designed into a compact, portable device for over-the-shoulder applications.
The 633 mixer features six inputs, with three high-bandwidth mic/line XLR inputs complete with phantom power, high-pass filter, input limiter and variable pan. Three additional line-level inputs appear on TA3 (mini-XLR) connectors. All inputs are assignable to any output bus. AES digital I/O, including support for AES42 digital microphones, is available.
The 633 offers 10-track 24-bit, 48 kHz uncompressed polyphonic or monophonic broadcast WAV file recording (96 kHz for eight tracks, 192 kHz for six tracks) or timecode stamped MP3 recording to CompactFlash and/or SD cards. All six inputs plus Left/Right and Aux 1/2, can be recorded to individual tracks. Similar to Sound Devices’ 12-input 664 Production Mixer, the 633 offers dual card slots that record to either one or both cards simultaneously, with the added ability to assign different tracks to each memory card.
The four-way power supply and Sound Devices’ proprietary PowerSafe technology allows for multiple, simultaneous power sources, including external DC on a Hirose 4-pin locking (12-18 V), two removable and independent L-type Lithium-ion batteries and internal AA battery powering (six-AA). The unit detects when power sources are removed and seamlessly transitions to an available power source. With its PowerSafe circuitry, when all power is removed the unit remains on for 10 seconds to close all file operations and properly shut down. With PowerSafe, a complete power loss has no effect on the recording. PowerSafe also provides two-second ‘power-on-to-recording’ so the mixer is ready for operation at a moment’s notice.
