miniDSP UMIK-X-4

Beschreibung

The miniDSP UMIK-X USB multi-channel microphone array can record up to 16 channels simultaneously, the A2B cabling enables daisy-chaining of multiple arrays and this is rounded off by the REW integration for multi-channel analysis.

highlights

• Multi-channel - multi-point microphone measurement system
• Up to 4xUMA4 MEMS microphone arrays can be connected in series
• Low distortion, high AOP, high SNR Knowles MEMS (SPH0655LM4H-1)
• 24bit 44.1/48kHz recording, ASIO driver
• USB to A2B® Module for multi-channel audio streaming over long cables (up to 40m)
• REW license for multi-channel measurement

The UMIK-X consists of one to four UMA4 microphone modules and a USB A2B interface to connect the modules to the computer. This allows between four and 16 microphones to be connected. The UMA4 modules are daisy chained together using a single twisted pair cable with Analog Devices' A2B protocol for multi-channel 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 sound field measurements. The distributed omnidirectional microphones in the array enable fast measurement and analysis in applications such as room equalization and distributed subwoofer tuning.

The UMIK-X is a UAC-2 compliant interface that comes with its own ASIO driver and is driverless for macOS and Linux. An ASIO driver is included for Windows. Last but not least, the UMIK-X is compatible with the new multi-channel measurement feature of Room EQ Wizard (from version 5.20). While this is normally a paid upgrade, a license for the upgrade is already included with the purchase.

The UMIK-X is now available in 2 complete, ready-to-use packages so you can get it up and running in no time! The basic package supports up to 16x channel recording (4 x UMA4 arrays).
