Hello
The 16 mic array board has an led near the usb connector and I do not know what it means when it is RED or BLUE. When powered up it flashes BLUE for 1/2 sec then back to RED. I have seen it turn BLUE and remain that color once or twice but usually it stay RED. Furthermore, I am not able to get much volume out of the mics so maybe it has some relation to the color of the led? I appreciate your input.

@Jim

That LED is simply for the booting process on the main board. No specific information relevant to your bootup I think.
The microphone have a high max SPL so if your signal is low, you might need to increase the sensivity by doing internal gaining inside your software. You do that with a bitshifting typically for a fixed gain value.

Hello, My signal is not low. I am speaking into the mic array (correct side up) within 10 cm at normal to high voice. The individual channel output is minimal. This image shows channel 1 output level: http://ibb.co/ypsxpXr. Is there a way to increase gain on the miniDSP? I do not have the software to adjust the speaker array gain.
