The Sound Devices 633 is a compact, lightweight Mixer/Recorder combination. It offers 6 analog inputs: 3x XLR inputs (with option for phantom power) and 3x line-level TA3 inputs. It can record simultaneously to an SD card, CompactFlash card or both, in mono or poly WAV or MP3 file formats. The Sound Devices 633 is made of carbon fibre and metal, weighs 1100 grams and comes in a mixer bag with cables. Its dynamic range is 114 dB. The recorder achieves 24-bit 192.000 Hz in WAV. Its dimensions are 6.0 x 24 x 14 cm.
