SE-231 Description The POPE Professional® SE-231 Graphic Equalizer is designed for modern sound reinforcement applications. Smooth band-pass filtering and transparent low-noise circuitry provide virtually distortion free operation. The SE-231 has been designed and engineered to exceed extremely high standards for design specification and audio performance. This flagship EQ is precise and flexible, with the quality components and innovative features necessary for top-level professional audio performance. The SE-231 filter sets utilize precision 1% resistors and 2% capacitors. The active gain elements used throughout are all ultra low noise, and low distortion, resulting in a total dynamic range specification of >=123dB, thereby making these equalizers perfect for all applications where precision processing and silent operation are of the utmost priority. Rugged construction and solid audio performance make these equalizers well suited for touring live-sound systems as well as for fixed installations.
