Audio System H-3300.1 D

With the H-3300.1 D, Audio System Germany presents a high-performance mono power amplifier from the HELON series, designed specifically for demanding subwoofer applications. Thanks to modern Class D technology, it combines enormous output power with high efficiency and compact dimensions. The high-quality SMD construction, a powerful MOSFET power supply, and extensive adjustment options allow for precise tuning to virtually any bass system. Whether for high-performance daily-driver systems or SPL-oriented competition vehicles—the H-3300.1 D delivers impressive power reserves and controlled deep bass at the highest level.

Features include a variable low-pass filter, a subsonic filter, continuously adjustable phase control, and a bass boost for selectively enhancing low frequencies. A clipping LED helps with optimal level adjustment, while the included RTC bass remote control allows for convenient operation from the driver’s seat. Comprehensive protection circuits also ensure safe operation even under heavy load.
