Details

Field mixer with five transformer-balanced mic/line inputs with phantom, high-pass, and limiters. Multiple outputs include XLR mic/line master outs, direct out, and two AES/EBU outs (four-channels). Built-in two-channel recorder (SD/SDHC card). Battery (4-AA) or external DC powered.

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.
