1 PRODUCT OVERVIEW
Thank you for purchasing a miniDSP UMA-8 USB microphone array. The UMA-8 is a high-performance yet low
cost multichannel USB microphone array built around XMOS multicore technology. Seven high-performance
MEMS microphones are configured in a circular arrangement to provide high-quality voice capture for a wide
range of applications.
Leveraging the onboard DSP processing, the UMA-8 supports voice algorithms including beamforming, noise
reduction, acoustic echo cancellation and de-reverb. Non-technical users can enjoy a plug&play experience,
while advanced users can fine-tune all DSP parameters with a realtime Win/Mac GUI for optimum performance.
The UMA-8 is a fully compliant UAC2 audio interface with driverless support for Mac/Linux and ASIO drivers for
Windows.
Depending on the loaded firmware, the UMA-8 has different modes of operation.
For the current release, the interface is running as a 2xIN (2ch Beamforming), 2 x OUT (Stereo out on I2S_OUT_0
/ Pin J3.1) configuration in the DSP mode. In the RAW mode, the unit is advertising as a 8xIN (7 x MEMS + 1 x
PDM input), 2 x OUT (Stereo out on I2S_OUT_0 / Pin J3.1).
The below sections will hopefully clarify how to install and configure the UMA-8. If any doubt/questions, feel
free to contact our technical support team.
