MATRIX Creator Microphone - Alexa voice control distance max. 2 Meter

Hello everybody,

I put the microphones from the Matrix creator in operation.

Here I encountered the following problem:

When I record the speech, the microphone is very quiet.

This makes itself, for example, in the software of Amazon Alexa noticeable. By using the input of the speech only with a maximum distance of 2 m from the device.

I tried to increase the gain in the library from 8 to 100, unfortunately this only has such a noise arises and in Audacity the signal is represented with an offset.

Is this normal or how can this be optimized?

Where can I Buy the MATRIX Voice?

I would be glad for an answer.

best regards
