WONDOM AA-AA21111 DAC/USB Interface Modules

The Wondom AA‑AA21111 is a USB to digital and analogue audio signal converter, designed to directly transform USB stream into S/PDIF and stereo analogue outputs. It leverages standards-compliant Full Speed USB controller and 16 bit delta‑sigma conversion, supporting sampling frequencies of 32, 44.1 and 48 kHz to ensure stable restitution immediately usable in audio chain.

Intended for compact systems and simplified integrations, it uses single Micro USB interface ensuring both power and data transfer, thereby enabling cabling reduction while guaranteeing rapid implementation. This approach extends to native driver-free compatibility under Windows and macOS, while integrated RCA outputs and 3.5mm jack facilitate direct connection to amplifier or headphones, ensuring immediate use without additional adaptation.
