GC-206BTB: my microphone isn't working

The Gemini Sound GC-206BTB has a noise gate on the MIC input that cuts out unwanted background sound. Because of that, quiet sounds won't get amplified, so a low-volume voice can seem like the mic isn't working.

Here's how to get the mic going:

1. Speak louder into the microphone to open the noise gate.
2. Check every connection between the microphone and the unit.
3. Make sure you're using a working audio cable, and swap in another one if you're not sure.

If the mic still won't work after that, contact customer support and we'll help you sort it out.
