MAIN FEATURES Professional quality performance--incorporates designs. Uitra-low distortion & studio-quality noise floor Fast Recovery circuitry reduces distortion at the edge of clipping and beyond Limiter with On/Off switch (decreases distortion that may become present when the CA AMP is driven at max levels without affecting overall sound levels) Easily handles 2-ohm loads all night long Switchable low-frequency filters (30 Hz ) protect speakers and increase headroom. Switchable inner crossover(150Hz)direct pumping subwoofers Detented gain controls calibrated in dB & volts Balanced 1/4" (6.3mm) TRS and XLR inputs for low noise Binding post and Neutrik Speakon outputs Comprehensive LED array i monitors operation and performance Independent DC, short circuit, subsonic, ultrasonic and thermal overload protection on each channel automatically protect amplifier and speakers Variable-speed fan for low noise, Rear-to-Front air flow prevents rack overheating.
