The 833 is the professionals tool for mobile and small productions. Like the popular Sound Devices 633, the 833 is small, lightweight, and compact. A tactile interface with dedicated faders, trim knobs, and PFL switches makes this mixer-recorder ideal for run-and-gun bag use.The 833 has 6 mic/line preamplifiers, 8 channels, 12 tracks, 6 analog outputs, and ultra-accurate timecode. Many features have carried over from the premium Sound Devices Scorpio, such as Sound Devices new preamplifier design, 2 SD card slots, dual L-Mount battery charging and powering, and an internal 256 GB SSD.Additionally, the 833 shares the same processing architecture and multiple FPGAs as the Scorpio. This enables the 833 to be fully routable, and any physical input can be routed to any track. The 833 features both digital and analog inputs and outputs, and has multiple powering options, so it will fit effortlessly into your existing kit.A built-in three band EQ may be set to either pre- or post-fade for each channel to tackle any problems directly on-set. Enable Dugan Automixing or MixAssist to automatically attenuate unused microphones in multi-microphone applications. Up to 8 channels can be automixed at a time. If you are recording in a noisy environment, enable the optional NoiseAssist or CEDAR sdnx plugins to suppress common background noises instantly on-location.Main Features:6 ultra low-noise, 8-Series microphone preamplifiers8 channels, 6 buses, 12 tracks6 analog outputsUltra-accurate timecode256 GB internal SSD, 2 SD card slotsUSB-A and C ports for SD-Remote app, linear fader control via MCU, keyboard, and file transferDugan Automixing/MixAssist for up to 8 channelsOptional NoiseAssist and CEDAR sdnx noise suppression pluginsSpecifications:Analog Inputs:Frequency Response: 10 Hz to 80 kHz 0.5 dB (192 kHz sample rate, re 1 kHz)THD + Noise: 0.005% max (mic in, 1 kHz, 22 Hz22 kHz BW, trim at 20, fader at 0, -10 dBu in)Equivalent Input Noise: -131 dBV (-129 dBu) max (mic in, A-weighting, 76 dB gain, 150 ohm source impedance)Processing EngineHighly extensible, full FPGA-based audio processing, 3 FPGAsSix-way ARM multiprocessor system64-bit audio processing precisionInputs:Mic/Line inputs: 6 total, all fully featured; 3 on full-size XLR, 3 on TA3Inputs:Mic-level inputs: (XLR, TA3): Class-A, discrete differential long-tail pair, 4k ohm input impedanceLine-level inputs: (XLR, TA3,): active-balanced, 4k ohm input impedance48 V phantom: full 10 mA to all 6 inputs simultaneously8 Total analog inputs: 6 mic-line inputs, 2 on returnsAES3 or AES42 available on XLR input 1AES42: +10 V, 250 mA available, mode-1, auto-ASRCUSB Audio: 2 InputsAux (3.5 mm: unbalanced 2-channel, 4k ohm input impedanceCom Rtn (TA3, 3.5 mm) balanced, 1-channel, 8k ohm input impedanceExternal Slate Mic (TA5): balanced, 8k ohm input impedance, menu-selectable 12 V phantomMaximum Input Level:Mic: +8 dBu (2.0 Vrms)Line: +28 dBu (19.5 Vrms)Aux: +18 dBu (6.2 Vrms)Com Rtn: +24 dBu (12.3 Vrms)External Slate Mic: +12 dBu (3.2 Vrms)Buses:6 Buses (L, R, 1-4)Left and Right Mix Bus receives post-fade isolated channels.
