Running the mic into a Sennheiser G4 body pack. In a quiet church setting I have to set it to -12db and the SQ5 mixer to zero gain. Simply superb audio quality; really, really good. A good bit better quality than the MKE2 microphone. Where this mic is especially good is with speech intelligibility. This mic has a way of making the spoken word seem more clear and understandable. The spoken word is more distinct, without degrading the quality of the sound. It is a little bit bigger than the MKE2 so it seems to work well as a lapel mic. Very happy with this microphone.
