At IBC2009, Sound Devices introduced the 552 production mixer, which includes a fully integrated digital audio recorder.
Well suited for simple run-and-gun applications and in complex multi-input/multioutput production setups, the Sound Devices 552 contains five precision, high-dynamic range, transformer-balanced microphone inputs with expanded gain and headroom. The studio-grade inputs have their own limiter, sweepable high-pass filter and pre- or post-fade direct output.
At the heart of each microphone input is a Lundahl input transformer, which provides freedom from interference in severe RF and EMI environments that are encountered in the field. The Sound Devices 552 has an integrated two-track, 24-bit digital audio recorder that writes broadcast WAV files or MP3 files to SD and SDHC media.
