SylphAudio D100 Low Gain, High Performance Stereo Class-D RTR Kit
This amplifier module is designed to deliver high-quality sound with exceptional midrange clarity and transparency. It is based on the TPA3251 chip, which is known for its superior performance in these areas.
The module features a versatile input section that can accommodate both differential and single-ended signals. This makes it compatible with a wide range of audio sources.
The opamp buffer section has been designed with a split supply, which eliminates redundant coupling caps in the frontend audio path. This enhances sound transparency and allows for better detail retrieval.
The module is equipped with the same official ATS heatsink for TPA3255 EVM that ensures efficient heat dissipation. This allows the amplifier to operate at its best performance levels, even when driving demanding loudspeakers.
The module also features solder jumpers for slave settings and accessible OSC IOM/IOP pads under the PCB. This makes it easy to configure the module for multi-device setups.
