The Microphone Arm Clamp attaches to your adjustable height table and holds your Microphone Arm in place. It’s extremely important that you do two things during this setup. First: make sure you tighten your clamp down nice and snug, as it’s not uncommon for people to bump into the mic and you don’t want the clamp to come off (snug is nice, but don’t overdo it or you could break something). Second: make sure the clamp isn’t too far away from the person speaking. If you clamp your Mic Arm too far away then your Mic will in turn be too far away, and then your audio quality suffers.
