With the Audiophonics TPA-S100, we offer you a Class D amplifier benefiting from a beautiful design, allowing it to deliver a comfortable power of 2x85W under 4Ω. It uses a Texas Instruments TPA3255 amplifier chip, characterized by a low distortion and a very low noise floor, for a precise and dynamic sound reproduction.

In addition to its two analog stereo RCA inputs and USB-B input, it also benefits from Bluetooth 5.0 connectivity thanks to the Qualcomm QCC3034 receiver chip. This ensures stable reception and allows you to take advantage of the high resolution codecs aptX and aptX HD. A DAC PCM5102 is responsible for decoding audio streams received via USB or Bluetooth.

We also find within the circuits of this TPA-S100 three AOP JRC 5532DD for its preamplifier stage or a volume and tone controller JRC NJW1194.

Finally, the amplifier includes a custom isolated and filtered power supply stage, allowing the delivery of a constant and clean electrical signal to the audio circuits.
