Description

ddHiFi TC44CPro USB-C - a headphone adapter that combines a high-quality digital-to-analog converter and amplifier. The high-quality chip from Cirrus Logic ensures clear, rich, and accurate reproduction.

Features:

  • Dual CS43131 DAC
  • Output power of 120mW at 32 Ohms
  • Supports PCM 32-bit/384kHz and DSD256
  • Signal-to-noise ratio of 125dB
  • Input format indicator
  • 4.4mm balanced output
  • Aluminum alloy body
  • Strap buckle

The 4.4mm balanced DAC has undergone testing in the first-generation TC44B, second-generation TC44C, and current TC44Pro, with sound tuning optimized once again. Completely new internal wiring and soldering make the sound more balanced, and the arrangement of digital connectors and analog ports has been improved.

The device's body is carved from an aluminum alloy, while the back panel is made of 1800D carbon. The DAC block features the dual CS43131 chip from Cirrus Logic, providing excellent signal-to-noise ratio and a wide dynamic range.

The USB connector and the 4.4mm headphone jack are connected to the board using silver solder, ensuring high signal transmission quality.

The amplifier's output power reaches up to 120mW at 32 Ohms. The DAC can work with a PCM signal of 32-bit/384kHz and native DSD256. The body of the adapter includes a strap buckle, making it more convenient to carry.

Power output

This is the useful power developed by the amplifier in the load resistance. Amplifiers are usually characterized by the highest power that can be obtained at the output, provided that the distortion does not exceed the specified permissible value. This power is called the output power of the amplifier.
