- Powered by high-performance TI TPA3255 series chips，with exclusive PFFB Post-Filter Feedback circuit design this Class D amplifier module delivers premium sound while retaining the high efficiency of Class D topology. With ultra-low THD+N as low as 0.0005%, idle noise down to 15μV, and a 125dB wide dynamic range, it reproduces pristine, distortion-free sound across the full audio band, fully restores delicate audio details for audiophile-grade listening experience.
- This 2-channel PBTL stereo amp board outputs up to 260W total clean power under 4Ω loads (1% THD+N), compatible with 2Ω, 4Ω, 6Ω and 8Ω speakers.Equipped with HA3588-BL high-current audio inductors, TDK film capacitors and low-ESR electrolytic capacitors, paired with precision ELNA Audio Capacitor, it maintains steady high-power output with zero sound distortion. Ideal for bookshelf speakers, floor-standing speakers and DIY active speaker builds.
- Full differential signal chain from input to output effectively suppress external electromagnetic interference, greatly improving sound separation. Independent power ON/OFF reset circuit eliminates pop noise when powering on/off, protects speaker units from instantaneous current impact, quiet startup without harsh popping sound.
- 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.
