Sure Electronics AA-AB31241 | Amplifier Module

The AA-AB31241 from Sure Electronics is a formidable Class-D amplifier board designed to deliver exceptional single-channel power in a compact, efficient package. As a booster module, it is ideal for upgrading existing audio systems, powering high-output subwoofers, or driving a single demanding speaker in custom installations, PA systems, or DIY audio projects where space and thermal management are critical.

This board leverages the Texas Instruments TAS5630 integrated circuit in a PBTL architecture, enabling it to produce a nominal 1 × 600 watts into a 2 Ω load with remarkable efficiency of 90%. The signal-to-noise ratio of 94 dB ensures clean, low-noise amplification, while selectable gain settings of 23, 29, 33, and 35 dB provide flexibility to match various input sources. Input is via RCA connectors, and speaker output uses robust screw terminals for secure connections. The board measures 152.4 x 114.3 x 38.86 mm, with a mounting hole diameter of 3.6 mm for easy integration. A current limit of 13.5 A and a minimum load of 1.5 Ω offer protection and versatility.

Whether for a high-fidelity home theatre, a professional sound reinforcement setup, or a bespoke audio project, this amplifier board delivers powerful, reliable performance with minimal heat dissipation.
