Page 6: Product Overview
RODUCT VERVIEW Thank you for purchasing a miniDSP UMIK-X distributed microphone array. The UMIK-X consists of one to four UMA-4 microphone modules and a USB-A2B interface to interface the modules to the computer. Between four and 16 microphones can therefore be connected. UMA-4 modules are daisy-chained to each other using a single twisted-pair cable carrying the A2B protocol at 44.1 or 48 kHz. -
