The UMIK-X consists of one to four UMA4 microphone modules and a USB-A2B interface to interface the modules to the computer. Between four and 16 microphones can therefore be connected. UMA4 modules are daisy-chained to each other using a single twisted-pair  cable carrying Analog Devices A2B protocol for multichannel audio at 24-bit/44.1 or 48 kHz. A single cable for audio + power for up to 40m distance! Applications include environmental monitoring and distributed soundfield measurement. The distributed omnidirectional  microphones in the array allow quick measurement and analysis in applications such as room equalization and distributed subwoofer tuning.

The UMIK-X is a UAC-2 compliant interface comes with its own ASIO driver and is driverless for macOS and Linux. For Windows, an ASIO driver is provided. Last but not least, the UMIK-X is compatible with the new multi-channel measurement capability of Room EQ Wizard (v5.20 and up). While this is normally a paid upgrade, a license for the upgrade is already included with your purchase.

The UMIK-X is now available for sale in 2 complete, ready to go packages to get up and running in no time! The basic package supports up to 8 x Channel recording (2 x UMA4 arrays) and 16 channel recording (4 x UMA4 arrays).

STOCK UPDATE (01/09/2020):  UMIK-X are now in stock and shipping.
