The H2200 amplifier gives you clean, dynamic power with sound quality and reliability and delivers true studio-quality sound. The power supply is the heart of an amplifier, converting raw AC power from the wall to clean DC for the audio circuitry. The power supply is the heart of an ampli?er, converting raw AC power from the wall to clean DC for the audio circuitry. The H2200 uses a powerful high-current toroidal transformer and ample ?lter capacitance to ensure generous energy reserves. This makes a critical difference in sound quality, allowing the amp to effortlessly punch out high level transients, even when driving a very low impedance.
