    • Q:

      We are making some changes in our choir area. To get the right sound, once installed, can the cable be lengthened without compromising the performance of the microphone?

        Thank you for your inquiry. I'm not sure how you would lengthen the cable after they are installed. The microphone is equipped with a 25 foot cable and may be shortened, but I'm not sure how you would lengthen it.

    • Q:

      Will this work in a baptistry

      We were thinking of mounting this on the wall in the baptistry which would put it about 10 feel above the heads of people in it. Would 1 on each wall work or is that a bit too close? They would be about 7 feet from each other.

      Thank you

        Thank you for your inquiry. I'm not sure how these would be wall mounted. They are designed to hang from the ceiling. It is highly recommended that wireless microphones be used in a baptistery because of the possibility of electric shock. Any wired microphones mounted in a baptistery area must be mounted in such a way that they cannot fall into the water and also that they cannot be touched by anyone in or near the baptistery. We also recommend that you use a qualified sound contractor for this type of installation to ensure that it is properly installed in a safe manor.

    • Q:

      Can the hanging condenser mic be used for a lecture live telecast

      We run classes .and telecast them to a few cities within Australia.
      At the moment the teacher has a lapel mic which works completly fine, while the students use hand held mics for the questions that they ask.
      The problem with the hand held mics is that they don't pick up the voice properly as the students forget to hold it properly.
      If we were to use the condenser hanging microphone for the students, I am worried it would pick up all the un-necessary noises and that the actual audio that we are trying to pick up would get lost as well???

      Another question is what are your thoughts if we had say 3 hanging mics in the classroom (ie one where the teacher stands)?
      The classroom is approximately 10m x 10m and the number of students attending hte class is roughly 20-30

        Thank you for your inquiry. Hanging mics are a good option, although I'm not sure I would use one that has such a tight pick up angle as the U853PMWU. I think the U853PMW with a 120 degree pick up angle would be more appropriate. You will pick up background noise, that is a given, although by engaging the low frequency roll off that is part of this microphone you can reduce some of this. This would also work for your instructor, but please note distant micing verses close micing (using the lav) will pick up more of the room sounds as well.
