      • A:

        Boundary Microphones are a popular alternative for micing a piano. However, using Boundary microphones on a piano can be quite challenging. For starters, mounting can be an issue. Typically, Gaffer (Gaff) Tape would be more commonly used to keep the boundary microphone in place. Do NOT use Duct Tape! The other challenge is microphone placement. For this, you will need to experiment until you get the sound you are looking to accomplish. A good place to start would be approximately 8" from the hammers, and use two microphones (one to cover the higher notes, another to cover the lower notes). Apart from using the 3:1 Rule of Microphone Placement, most of the time, it is best to move the microphones around and stop when they sound good to you.

        Although the PRO44 would be a good microphone to use, the U851R would be a better microphone. This is because the U851R can handle 20dB more of SPL (Sound Pressure Level), which will better handle the dynamics of a piano.

    • Q:

      what would you recommend for a ceiling mount microphone

      My supplier has recommended the Pro 44 for connection to a DVR at a customer counter application. I wish to ceiling mount it. Is there a different microphone that would be better suited for this application
      Asked on 1/17/2014 by tecvideosecurity from Winnipeg, MB, Canada

      • A:

        Thank you for your inquiry. Please note that connecting any microphone directly into a DVR may be problematic because the DVR may be expecting a "Line Level" input. Also, the microphone requires phantom power. You may need a preamp or mixer to boost the output of the microphone as well as provide phantom power. Another choice for a ceiling microphone would be the ES945. Please note you would still have the same issues as described above, but the form factor may better suit your need.

        Thank you for your inquiry. The microphone requires phantom power from a mixer or other audio device. It cannot be connected directly to a DVR via RCA connectors.

    • Q:

      Adjustments to amplifier?

      I've been looking at several low profile boundary mics for my place of worship. We have an amp of a different brand that I will not name. Will I need to make any adjustments to my amp to get the best sound quality from one of your mics?

      • A:

        Thank you for your inquiry. You almost always need to make adjustments with any microphone. Such things as volume and EQ need to be set to get the sound you are looking for based on the room accoustics.

    • Q:

      How does this mic compare with ES961 performance and RFI
      Asked on 3/1/2012 by pkpk

      1 answer

      • A:

        The ES961 is a mic better microphone and includes our UniGuard technology for filtering and resisting RFI. The Pro44, while being a nice microphone, does not have the UniGuard technology.

      Range?

      I have a conference table of 30 feet with people sitting on all sides. How many of these microphones would be required to pick up anyone sitting at the table?

    • Q:

      can I install it on the ceiling and using it to pick up sound from people sitting down? is the sound going be some how good ? how it's powered?

      • A:

        Thank you for your inquiry. Even though the microphone has keyhole slots on the bottom to hold it down, I would not mount it on a ceiling because I would be afraid that it could fall and that would be safety issue.
