DESC: The all-new A500/2 offers Precision Power clarity & flexibility combined with value pricing, while the more powerful A800/2 and A1000/2 continue the heritage of pure class AB Darlington-configured complementary bipolar output stages driven by massive MOSFET power supplies. Advanced Instrumentation Inputs reject up to 40dB of induced interference, assuring an ultra-low noise floor. Ultimate system flexibility is assured via the full-featured built-in crossovers that control internal and external frequency assignment.
