Product Introduction
Thanks for choosing the PT-C-DAC Digital to Analog Audio Converter, which is designed to convert digital S/PDIF (coaxial or Toslink) audio inputs to analog stereo audio (L/R RCA and 3.5mm) outputs.. Simultaneously, the converter provides a coaxial S/PDIF output for digital audio extension.
Features
- Converts digital S/PDIF (coaxial or Toslink) audio inputs to analog stereo (L/R RCA and 3.5mm) audio outputs.
- Coaxial S/PDIF output for digital audio extension.
- Input support up to 24-bit/192 KHz (PCM, Dolby Digital are DTS formats are passed through via coax S/PDIF).
- Provides Micro-USB port for power cable connection.
- Easy to install and simple to operate.
- Compatible with coaxial or Toslink interface digital audio devices such as CD, DVD, BluRay, Playstation, XBox, computer, A/V receiver, etc.
- Ideal for interfacing between modern digital audio/video devices with analog amplifiers or active, self-powered speakers.
Packing List
- 1x PT-C-DAC Digital to Analog Audio Converter
- 1x Power Cord (USB-A to Micro-USB)
- 1x User Manual
Note: Please contact your distributor immediately if any damage or defect in the components is found.
Panel Description


① Power LED: The LED illuminates blue when power is applied.

- ② TOSLINK IN: Digital Toslink audio input.
- ③ COAX IN: Digital coaxial audio input.
- ④ 3.5mm OUT: Analog stereo audio output.
- ⑤ RCA OUT: Analog stereo audio output.
- ⑥ COAX OUT: Digital coaxial audio output (pass-through).
- ⑦ DC 5V: Micro-USB port for power cable connection.
Note: When both digital inputs, Toslink and coaxial are connected to audio source devices, the coaxial audio source device will automatically be selected as input source.
