SD552 Production Mixer
Sound Devices presents the 552 Production Mixer, the most technologically advanced portable audio mixer ever made. Using the best analog and digital technologies, along with advanced mechanical construction, the 552 gives professionals a superb sounding, compact, lightweight and power-efficient mixer that is equally at home in simple run-and-gun applications or in complex multi-input, multi-output production setups.
The 552 contains five precision high-dynamic-range transformer-balanced microphone inputs with expanded gain and headroom. Each input accepts audio sources of various types and levels. Inputs have their own limiter, sweepable high-pass filter, and pre-or-post-fade direct output.
