SylphAudio D400M P05 TPA3255 PFFB Mono PBTL RTR Kit

$122.00 USD - $188.00 USD Sold Out

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

This versatile amplifier boasts a 2Ω load capability, effortlessly handling demanding speakers like reactive or capacitive loads.

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

Choose between full differential or single-ended signal options to optimize your audio experience according to your setup.

The split supply in the opamp buffer section deletes the redundant coupling caps in the frontend input.

With a TVS diode for power supply surge protection and accidental reverse polarity protection*.

The voltage supervisor IC ensures silent turn on-off transitions, preventing annoying pops or clicks.

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

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.
