500-Watt Parallel/Bridge Subwoofer Amplifier with Dynamic Bass Optimization Circuit.Slope-selectable variable electronic crossovers -The BPX500.1 is equipped with a variable electronic crossover capable of setting the slope rate at 12dB or 24dB per octave. The crossover adjustment range is 32Hz - 320Hz. Unlike conventional mono subwoofer amplifiers that only deliver their maximum power into a single impedance, the BPX500.1 is a two-channel amplifier that can be bridged to deliver double the voltage of a single channel into impedances between 2 and 4 ohms. The two channels can also be connected in parallel - that''s right, parallel - to provide double the current of single channel into impedance below 2 ohms. This feature is patented and unprecidented in car audio amplification. Thanks Crown! Dynamic Bass Optimization (DBO) - This provides variable filtering with adjustable ''Q'' below 100Hz, far beyond conventional ''Bass Q'' circuits, by allowing the low-frequency output to be optimized for specific subwoofer applications. Frequencies below an enclosure''''s tunign frequency can be attenuated, preventing damage to the subwoofer and allowing the amplifier''s power to be better utilized Full-range preamp outputs - In the event that multiple amplifiers are used in an application, this feature allows for streamlined system hookup. No high-loss Y-adapters or splitteres needed. The BPX500.1 comes equipped with a remote bass level control allowing you to optimize bass output for specific music or preferences from the driver''s position.
