AD 24

The Swissonic AD24 is a high performance 24 bit 8-channel A/D converter capable of operating at both 44,1 and 48 kHz sample rates, with choice of internal and external clock. State-of-the-art technology and extreme simplicity of operation, combined with a competitive price make the AD24 obvious choice for all digital audio applications. The AD24 is compatible with a wide range of ADAT optical equipment like PC/Macintosh soundcards, consoles, tape decks, F/X units and more.
