For fine-tuning a sound system, nothing beats a third-octave equalizer. It can “zoom in” on problem areas without affecting neighboring frequencies.
The CPQ-1131 can be used to compensate for room acoustic anomalies, beef up speaker system deficiencies, manually control feedback and a host of other situations where precise tonal control is required.
It includes an infrasonic filter to cut woofer cone flutter caused by stage rumble and mic thumps and has switchable ±6dB “narrow” or ±12dB “broad” fader adjustment.
To say that Crest knows equalizers is an understatement. We’ve been designing EQ circuits for decades as part of our large mixing consoles. We know how to make them quiet…and how to keep them from introducing phase distortion into the sound.
The CPQ-1131 is built with high-quality components and is engineered to withstand years of hard use in mobile or fixed installations.
