Q:i own a Audio Technica AT871R Cardioid Condenser Boundary Microphone i cant find it on this web sight, but the mic will not pick up any sound at all? how to i set it up?
A:There are a couple of possible reasons. This is a condenser microphone and therefore requires Phantom Power in order to operate. Phantom Power is an external source of power used for all condenser microphones. If you are using Phantom Power and it is still not working, that would be a Service issue and would need to come in to get fixed. You can find information on sending products in for Service (in the US) at www.audio-technica.com/service
Q:does the mic default to mute when power is applied?
A:Thank you for your inquiry. The microphone is OFF when powered up (if phantom power has been off for at least 15 seconds) when in the Touch ON/OFF mode.
