Description

Alfatron CVDAC

The Alfatron ALF-CVDAC Digital Audio Converter is designed to convert coaxial or Toslink digital audio input to analogue L/R and 3.5mm audio output. Simultaneously, the converter provides COAX SPDIF output for a digital audio extension.

Features Products

 

  • Supports audio distribution splitting one audio source into three audio outputs
  • Converts coaxial or Toslink digital audio input to analogue L/R and 3.5mm audio output
  • COAX SPDIF output for a digital audio extension
  • Supports up to 24-bit / 192 kHz input (PCM, Dolby Digital or DTS formats for digital audio extension only)
  • Provides Micro-USB port for power cable connection
  • Easy installation and operation
  • Compatible with coaxial or Toslink interface digital audio devices: CD / DVD, PS3, X-Box360, Blu-Ray player, Computer, A/V receiver, etc
  • Ideal for interfacing between modern digital audio / video devices with analogue amplifiers or self-powered speakers
