[D400M P05] TPA3255 Mono PBTL RTR Kit

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

Signal Options: Offers the flexibility to choose between full differential or single-ended signal options.

Replaceable Opamp IC Socket: Allows users to tailor their sound preferences by customizing the amplifier's audio signature through interchangeable opamp ICs in the input stage.

Split Supply Design: The opamp buffer section features a split supply design, eliminating redundant coupling capacitors in the frontend input, enhancing signal integrity and clarity.

2Ω Capability: Can provide 20Hz-20kHz, 600W clipping conditions on 2Ω without going into protection mode.

Protection Features:

TVS Diode: Provides surge protection for the power supply, safeguarding against voltage spikes.

Reverse Polarity Protection*: Prevents damage due to accidental reverse polarity connection, ensuring operational safety and longevity.

Voltage Supervisor IC: Ensures silent turn-on/off transitions, minimizing audible pops or clicks during operation.

Efficient Cooling System: Equipped with the official ATS heatsink for TPA3255, maintaining optimal performance even under intense 2Ω subwoofer setups, by effectively dissipating heat and regulating temperature.

Multi-Device Configuration Simplification:

Solder Jumpers: Facilitate easy configuration for slave settings, simplifying multi-device setups.

Accessible OSC IOM/IOP Pads: Located under the PCB, these pads expand the number of audio channels effortlessly, enhancing system scalability and versatility. (Refer to SLAA787 for detailed instructions.)

*Requires power supply with overcurrent protection.

Elna Silmic II input coupling caps.
