The Lark M1 has three volume levels: high, medium, and low, with the default volume level being medium. The volume can be increased to the maximum by pressing the "+" button twice on the receiver.
You can also adjust the recording volume by adjusting the distance between the transmitter and your mouth.
Note: Please remove the blue insulating film from the top of the transmitter before the first use.
If the sound is low even after the sound on transmitter is full you can turn off noise cancelation and if the sound is still low you can remove the cat fur attachment from your mic. Hope this will help you
