Product Details

↓ Details provided by DD ddHiFi

Aesthetically pleasing
TC44C (Blue). USB DAC and Amplifier.

The 3.5mm, 4.4mm and USB-C ports are well arranged in a straight line despite their different sizes.

  • Support up to PCM 32bit/384K | Native DSD256
  • USB-C version provides one USB-C cable TC05
  • Lighting version provides a TC05 + a Lightning cable MFi06S

Acoustically, dual-channel balanced

It adopts dual DAC chips Cirrus Logic CS43131 for decoding, which provides better SNR, dynamic range, signal range of the audio source, distortion and fidelity.

OCC copper internal connection line

The headphone socket, especially the 4.4mm, has many pins, so opening holes on the circuit board may seriously affect the circuit's wiring. The circuit board design of TC44C simplifies the wiring by separating the socket from the mainboard. Moreover, OCC copper is for connection and lead-free soldering tin with 3% silver for soldering.

The concealed LED indicator

The transparent 4.4 mm and 3.5mm socket can transmit light to indicate the status: Blue indicates PCM output, and Green indicates native DSD decoding output. However, when the socket is plugged in, the light will not be visible.

Provided OCC copper USB cable

It provides a high-quality OTG decoding cable in the package. The cable is made of high purity silver-plated OFC with teflon and PVC double insulation. The plug is integrally formed, which is sturdy and durable, but also ensures high quality sound.

*If you purchase the Lightning version, an additional Lightning OTG decoding cable of model will be provided as well.
