Sure Electronics AA-AB32511 | Amplifier Module

The Sure Electronics AA-AB32511 is a high-performance Class D audio amplifier board designed to deliver exceptional power and clarity in a compact, efficient package. Capable of driving two 4-ohm speakers with up to 500 watts per channel, this booster module is ideal for demanding audio applications such as home theatre systems, active speaker builds, or professional sound reinforcement setups where reliable, high-output amplification is required.

At the heart of the board lies the Infineon Technologies IRS2092 driver IC, which enables a remarkable 90% efficiency while maintaining a clean signal path. The amplifier achieves a signal-to-noise ratio of 97 dB (A-weighted) and a low total harmonic distortion of just 1% at 2 x 50W into 8 ohms, ensuring accurate and detailed sound reproduction. With a minimum load impedance of 4 ohms and a fixed gain of 30 dB, the board offers robust performance across a wide range of speaker configurations. Input is via RCA connectors, while speaker and power connections are made through secure screw terminals, simplifying integration into custom enclosures or existing systems. An integrated current limit of 18 amps provides protection against overloads, making this board a dependable choice for sustained high-power use.
