Integrated Amplifier Class D TPA3116 Bluetooth 5.3 2x100W 4 Ohm

This Class D integrated amplifier is designed to drive bookshelf and floor-standing speakers, delivering 2×100W into 4 ohms, relying on a dual TPA3116D2 architecture to ensure high efficiency and stable load handling.

Intended for versatile domestic use, it combines NE5532-based preamplification with tone control and Bluetooth 5.3 connectivity, allowing the sound signature to be adjusted while providing easy access to wireless sources.

2x100W Amplification

This integrated amplifier relies on a dual TPA3116D2 chip to deliver 2×100W into 4 ohms, enabling efficient drive of bookshelf speakers while maintaining high efficiency and contained thermal dissipation. This Class D architecture allows energetic reproduction with stable load handling while limiting losses, resulting in consistent performance in domestic configurations where compactness and power output must coexist.

Preamplification

The preamplification stage is built around an NE5532 chip, integrating an analogue processing stage that operates upstream of the power amplification in order to adjust the signal without degrading its structure. Beyond simple volume control, this approach extends to bass and treble adjustment, allowing the tonal response to be tailored to the speakers or room acoustics, while preserving overall signal intelligibility.

Bluetooth Connectivity

The integration of Bluetooth 5.3 enables wireless audio transmission with reduced latency and improved stability, facilitating use with mobile sources without requiring a wired connection. This connectivity is designed for everyday use, allowing rapid switching between sources while maintaining operational continuity within a domestic audio system.
