SylphAudio FB100 Ultra-High Performance Stereo Class-D Amplifier RTR Kit

$176.00 USD

Designed with advanced PFFB without compromising the TPA3251's output power, resulting in remarkably low distortion and minimal noise output. Its IMD, high-frequency distortion, and other metrics stand out as best in class.

The heatsink employed is ATS-TI1OP-519-C1-R3 (designed for TPA3255), ensuring that the idle temperature does not surpass 48 degrees Celsius at a free air ambient temperature of 28 degrees Celsius when used with the TPA3251.

The preamp section utilizes a split power supply, eliminating the need for an additional set of input coupling caps on the preamp frontend. This configuration allows for only one series input coupling cap in the signal path per amplifier, eliminating any coloration, or haziness that additional input coupling caps might introduce to the overall sound. The module comprises four single-ended amplifiers, configured with 2-channel differential inputs and 2-channel BTL outputs.

Additionally, it features dedicated post regulators for each preamp rail and a separate post regulator for the TPA chip supply.

A heat spreader has been placed on the preamp section to ensure cooler and more reliable operation. We've employed special layout techniques to produce an ultra-low THD+N preamp, a primary contributor to the overall sound of the amplifier.

Oversized film capacitors for the class-D output filter and Zobel network, and flat wire output inductors have been meticulously selected to elevate the overall sound quality.

Upon listening to this class-D amplifier module, you'll immediately associate it with the word "refinement." An endgame amplifier for small music studios or home audio.
