The Blustream ADC11AU is an analogue audio to digital audio converter designed to convert stereo analogue Left/Right audio into both Optical and Coaxial digital audio concurrently. This device is particularly useful for integrating older analogue audio sources with modern AV amplifiers that primarily use digital audio inputs. It serves both home and professional audio applications, offering a straightforward solution for audio signal conversion.
Function Description:
The primary function of the ADC11AU is to take an analogue stereo audio input (via RCA connectors) and convert it into a digital PCM audio signal. This digital signal is then simultaneously outputted through both SPDIF Optical and Coaxial digital connections. This concurrent output allows for flexible connectivity options, enabling the user to connect to multiple digital audio receivers or choose the most suitable digital format for their setup. The conversion process ensures that the analogue audio is transformed into a 16-bit 48 kHz digital audio stream, a common standard for digital audio transmission. The device is designed for plug-and-play operation, ensuring ease of use without complex setup procedures. Its compact size also makes it easy to integrate into various audio systems without taking up significant space.
