Two independent compressor⁄limiter⁄gates in a road-tough, steel, single-rack space (1U) housing with built-in adjustable Dynamic Enhancer and Interactive Ratio Control eliminate the noise floor during quiet sections. Protect your expensive amplifier and speakers from damage due to subsonic frequencies and overload with this US Blaster Soundprocessor!
To improve the intensity of the stereo effect, to enlarge the stereo bass, and to let your bass sound dry and punchy or full, this new US Blaster Sound Processor is the only choice. It has great effect!
