Sure Electronics AA-AB32192 | Amplifier Module

The Sure Electronics AA-AB32192 is a compact yet powerful Class D audio amplifier board, designed to deliver exceptional performance in a space-saving footprint. Engineered around the Texas Instruments TAS5630 chipset, this module provides 2x300W into 4 ohms, making it an ideal solution for high-fidelity sound reinforcement in custom audio builds, active speaker systems, or portable PA applications. Its robust construction and high efficiency ensure reliable operation even in demanding environments.

This amplifier board excels in a variety of use cases, from powering bookshelf speakers in a home theatre setup to driving full-range drivers in a DIY boombox or car audio upgrade. With a minimum load impedance of 3.5 ohms and a current limit of 13.5A, it offers flexibility for different speaker configurations while maintaining stable performance. The 91% efficiency rating minimises heat generation, reducing the need for bulky heatsinks and enabling compact enclosure designs.

Key technical features include an 89 dB signal-to-noise ratio for clear, low-noise audio reproduction, a gain of 28 dB, and dual RCA inputs for easy integration with preamplifiers or audio sources. Output connections are via screw terminals or PCB solder pads, while power is supplied through a screw terminal or a 5.5/2.5 mm DC jack. Measuring just 121.92 x 91.44 x 38.86 mm, this board is a versatile and efficient choice for audiophiles and hobbyists seeking high-power amplification in a compact form factor.
