The MPA575 is Ingram Engineering's foray into the 500-series format. It features a lightly colored mic pre-amp, compressor, and a unique EQ with combined low and high frequency control that allows broad tone adjustments with a single control knob. Together, they form a mini channel strip that performs all essential analog signal processing functions needed before committing audio to a recording medium. The MPA575 is ideal to use as a standalone mic interface or in combination with full featured hardware or plug-in compressors and EQs for more surgical audio processing.
