The miniDSP PocketADC is a compact, high-resolution analog-to-digital converter (ADC) that accepts a stereo analog input on single-ended (RCA) connectors and converts it to SPDIF coaxial and TOSLINK optical digital outputs. This pocket size converter supports flexible sample rates of 44.1 to 192 kHz, settable with DIP switches. Combined with extremely low noise floor performance, it provides optimal digitization of your favorite analog audio content. Applications include converting your analog audio sources to Digital (SPDIF/TOSLINK), while adding a high quality ADC to your existing system. No computer is required to create analog conversion for an all digital audio system.
