- Studio-Grade HiFi Performance with High Power Output Powered by high-performance TI TPA32xx series chips (TPA3255/TPA3251 optional), this Class D amplifier module delivers premium sound while retaining the high efficiency of Class D topology. It supports up to 480W (TPA3255, PBTL mode @2Ω), 260W per channel (TPA3255, BTL mode @4Ω) and 140W per channel (TPA3251, BTL mode @4Ω) output. With ultra-low THD+N as low as 0.0005%, idle noise down to 15μV, and a 125dBA wide dynamic range, it reproduces pristine, distortion-free sound across the full audio band, delivering an immersive listening experience from delicate treble details to powerful, tight bass.
- Highly Flexible Configurations for Wide Compatibility This amp module supports both 2-channel BTL stereo mode and 1-channel PBTL parallel bridge mode, with a single board design fully compatible with TPA3251 and TPA3255 chips. It adapts to 2Ω-8Ω load impedance, works with a 36V~51V single DC power supply, and is compatible with multiple high-quality inductors (7G23B/VER2923/APG2923/HA3588). Whether you are building a 2.0 stereo bookshelf system or a high-power mono subwoofer amplifier, it perfectly matches your custom needs.
- Professional Low-Noise & Low-Distortion Circuit Design To achieve ultimate audio performance, we adopt a fully differential signal chain from input to output, which effectively suppresses common-mode noise and environmental interference. The critical audio path uses high-precision MELF resistors, combined with optimized PFFB post-filter feedback technology, an upgraded analog input front-end, and premium-grade components. All designs work together to minimize noise and distortion across the entire audio frequency range, ensuring purest signal transmission and studio-level sound reproduction.
- User-Friendly Design for Easy DIY & Integration This amplifier module is built for both DIY enthusiasts and professional developers. It integrates an on-board low-noise analog power supply and housekeeping power system, eliminating the need for complex external power circuits. The dedicated power ON/OFF reset circuit effectively suppresses pop noise during startup and shutdown, protecting your speakers from impact damage. It supports both balanced and unbalanced input sources (with an optional input buffer for single-end input), and features a compact 120mm85mm40mm form factor, easy to install into various audio enclosures and custom projects.
- Wide Application Scenarios & Reliable Quality This high-quality audio amplifier module is ideal for a wide range of scenarios: DIY speaker building, home theater systems, active speakers, car audio modification, professional audio engineering, and commercial audio equipment. We offer a full range of SKUs with different power levels, configurations, and component options (including a no-heat-sink version for custom cooling solutions). All products are manufactured in Mainland China with strict quality control, contain no high-concerned restricted chemicals, and deliver stable, long-lasting performance for your audio projects.
