If you're using the ZelloWork PC application you may see a few different options for increasing microphone volume.
1. The recording device will change the Windows Microphone Properties level. Turn this level all the way up to increase the microphone volume.
2. A Microphone boost may be available in the form of a check mark or as a level. This option will only be available if your PC's audio drives support it. Turn it up or on if you want to give your microphone a boost.
3. The recording amplifier can be turned on if you've tried the options above and your mic is still not loud enough. Be careful with this setting, it's a digital audio amplification so it can distort recordings. Increase a couple dB at a time and test to make sure your recordings still sounds ok.
