SylphAudio D400M P05 TPA3255 PFFB Mono PBTL RTR Kit

$122.00 USD - $188.00 USD

TPA3255 in a mono PBTL PFFB configuration.
250W into 4Ω at 1% THD+N.

Amplified Performance: This versatile amplifier boasts a 2Ω load capability, effortlessly handling demanding speakers like reactive or capacitive loads for a captivating audio performance that is free from distortion.

Custom Sound: Tailor your sound to your preferences with the replaceable opamp IC socket in the input stage, allowing for endless customization and a personalized audio signature.

Crystal-Clear Clarity: Enjoy pristine audio clarity even in challenging listening conditions with the noise-free configuration, delivering every note and nuance with precision.

Flexible Signal Options: Choose between full balanced or single-ended signal options to optimize your audio experience according to your setup.

Pure Sound: The split supply in the opamp buffer section deletes the redundant coupling caps in the frontend input, which ensures a purer sound.

Enhanced Protection: With a TVS diode for power supply surge protection and accidental reverse polarity protection*, your investment is safeguarded for long-term use.

Smooth Transitions: The voltage supervisor IC ensures silent turn on-off transitions, preventing annoying pops or clicks for a seamless audio experience.

Efficient Cooling: Even during intense 2Ω subwoofer setups, the official ATS heatsink for TPA3255 keeps the amplifier's temperature, maintaining optimal performance.

Multi-Device Setups Made Easy: Simplify multi-device configurations with solder jumpers for slave settings and accessible OSC IOM/IOP pads under the PCB, expanding the number of your audio channels effortlessly. (See SLAA787 for details.)

*Requires power supply with overcurrent protection.
