There's various options on the C3 - microphone pattern, Attenuation Pad. Check some basics:
make sure that the attenuation pad is off
make sure you are using the mic in "super-cardioid" or "omnidirectional" mode
make sure you are speaking into the correct part of the capsule.
Perform an elimination test - check the microphone with another cable and ...
Very simply put, no - this is not possible.
However in order to explain why this is the case it will be necessary to delve deeply into topics such as microphone design to a level that will probably exceed the constraints of this text box.
Suffice to say, acoustic microphones can be designed to work across a very wide range of frequencies however it ...
frequencies above what microphone allows
Microphones have a frequency response curve. This is a random example:
The exact shape of the diagram is different for each microphone, but they all have one thing in common: the response will be as close to flat as possible in the range we're usually interested in (20 Hz- 20 kHz for full-range audio microphones), ...
For this sort of application you probably want a mixing desk that can handle automixing - something like a Yamaha QL-1 which has an in-built Dugan Automixer. This will significantly help with the noise-floor. Also you need to look and see how the mics are being used. IF the microphones are a long way from the subjects, then you will definitely get noise ...
From the manual for the Scarlett 2i2:
The preamp gain is appropriate for microphones when an XLR plug is inserted, and for higher level signals when a jack plug is inserted.
Get a jack->XLR adapter, preferably the device listed by ojacques because you also need the 2.7 V power supply.
Rode has now a device which allows to plug in microphones which need to be powered by power usually provided by smartphones (2.7v) through TRRS such as Rode's Lavalier Go or Shure's MVL/A to a USB sound card or any mic entry using XLR.
This is Rode VXLR+. The XLR has to provide 12-48V phantom power.
From Rode's site:
The VXLR+ is a 3.5mm female TRS ...
These mics are unsuitable for recording low-SPL sources as they are very noisy. The main reason why they are so noisy is the fact that the capsules are absolutely tiny. They can be used successfully for applications such as drum overheads and recording loud spot-fx, but I would not use them for anything such as ambience recording as the self-noise is too ...
Referencing both manuals for the Snowball Blue Microphone (and this manual) which provide similar information with different descriptions of the settings, this switch controls the pickup pattern,
Setting: Cardioid (capsule),
Applications: speech, vocals, podcasting
Picks up sound from the front, ideal for podcasting, game streaming or recording ...
