Sure Electronics AA-AB32514 | Amplifier Module

The AA-AB32514 2x500W Class D Audio Amplifier Board from Sure Electronics is a high-performance booster module designed to deliver exceptional power and clarity for demanding audio applications. This T-Amp board is ideal for custom speaker builds, home theatre systems, and professional sound installations where robust, reliable amplification is required. Its compact footprint makes it suitable for integration into bespoke enclosures or rack-mounted setups.

Technically, this amplifier board operates in Class D topology, achieving an impressive 91% efficiency to minimise heat generation and power loss. It provides two channels of amplification, each capable of delivering 500 watts RMS into a 3-ohm load, with a minimum load impedance of 3 ohms. The signal-to-noise ratio of 95 dB ensures clean, low-noise audio reproduction, while the 30.5 dB gain offers ample headroom for dynamic peaks. Input is via RCA connectors, and output connections are made through screw terminals or PCB solder pads for secure wiring. The board measures 152.4 x 114.3 x 38.86 mm and features a current limit of 21.5 A for protection. With its high power output and efficient design, this module is a superb choice for audiophiles and engineers seeking a versatile, high-fidelity amplification solution.
