3E Audio PFFB

Malanced Class D Amplifier Module TPA3255 BTL 2x225W / PBTL 1x250W 4 Ohm

3E Audio PFFB Module Amplificateur Stéréo Class D Symétrique TPA3255 2x 225W 4 Ohm

The 3E Audio PFFB module is a high-performance Class D amplifier that can operate in stereo (BTL) or mono (PBTL) mode. It is based on the use of TPA3255 amplifier chips allowing it to develop an important power of 2x225W or 1x250W under 4Ω. A power that it provides while revealing a precise and dynamic restitution. It incorporates an advanced feedback design (Post Filter Feedback) and a proprietary high speed error correction system (PurePath™ Ultra-HD). This technology achieves a very low level of distortion across the entire frequency band and superior audio quality.

By combining Post Filter Feedback, an enhanced input stage and high quality components, the 3E Audio PFFB module achieves incredibly low noise and distortion for clear and transparent playback.

Excellent quality
I had to wait for quite some time to get this modules but they are worth waiting. The modules are (compared to a lot of other TPA3255 modules) of excellent quality. A large milled heat sink with tapped holes to fix the modules in an enclosure, high quality parts, precisely aligned (SMD)components, and larger/heavier components fixed with an elastic adhesive. I haven't tested them yet but I am quite confident that they sound as good as they look.
