What can I do to fix the K683A from clipping?
It is a rather sensitive microphone designed to pick up the clarity of sound. But if your voice is towards treble in the first place, then you have to pay a bit more attention to the level setting. And speaking of which, the volume dial level is the most crucial. Thus, please turn down the control to 60%, set the input level under computer audio settings to 80% and keep the speaking range around 5 inches.
It is much better to open up a software, such as OBS or Audacity, which has a level meter to gauge the loudness of your voice. When the meter moves between -16 dB to -12 dB, you are getting pretty decent sound. If not, then turn down or up the dial to have better better-suited level setting.
How to Prevent K683A from Picking Up Speaker Sound in Zoom?
Instead of using speakers, either internal or external, please use headphones or earbuds to connect to your computer or K683A. Then the mic will not pick up sound from the output device, thus no more echo will be heard.
