  • Q & A

    Is this mic a good choice for stage performances ? I need to hear the stage and audience. Also can it be used with ATW-T102x block xmitter?


    Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    Can you tell me if this product is compatible with Pevey Mixer board model PV20. I plugged this microphone into the board but I get no sound.


    This mic should be compatible with your board. It is a condenser microphone, which will require Phantom Power in order to operate. Ensure you have Phantom Power activated on your board. If your problem persists, call us in Audio-Solutions at (330)-686-2600 ext. 5000 so we could dive a little deeper into your issue.


    Can this mic be used to mic a spinet piano by mounting it on the underside of the lid, pointed towards the sound board and hammers?


    Yes, boundary microphones like the PRO42 are often used to pickup the sound inside of pianos.


    We are DVR company and one of our customer is using this mic for interview recording. The DVR has standard Line level audio input 3.5 mm jack and connected directly to mic. They are experience lot of static and voice is difficult to understand. Any suggestion or thoughts.


    You will need to plug the PRO42 microphone into a MIC level input. This means you will need a microphone preamp in line between the microphone and the LINE level input of the DVR.


    Using for choir where should i place these? will probably need 2-3 of these mics I'm trying to get away from my condenser boom mics and use a more discrete mic for my choir which have about 14 members, where could I place these if i can use them. Thanks


    Thank you for you inquiry. Please note that these are designed to sit on a hard surface. A boundary microphone uses the direct audio waves as well as the sound reflected off the hard surface. If these are placed on carpeting much of the sound will be lost. The pick angle of the microphone is 60 degrees right and left of center and 60 degrees up. Plan for placement around that.


    Broken wires There are 2 orange and 2 yrllow wires. Do not know if polarity is an issue when repairing break. Please advise


    Thank you for your inquiry. . Please call our service department at 330-686-2600 option 4. They can help.


    Special Application I am a technician for a slow-motion camera used in the motion picture industry. I don't know much about audio equipment! I would like to mount this microphone to the camera and cable it back to my control station 150' away so that I can hear the director's instructions. What kind of equipment would I need at my control station to make this possible. Thanks!


    Thank you for your inquiry. You would need a 150' of xlr to xlr microphone cable and a mixer that provides phantom power and some type of sound play back (Speakers or headphones).


    Table Mic and Connectivity I have a small PA system with two inputs for 1/4 inch mic jacks. Three people present from a table with an 50-60 person audience sitting in front of them. Would two of the mics sitting about two feet in front of the presenters pick up their voices well? Are there adapters to convert XLRM to a standrd 1/4" jack?


    Thank you for your inquiry. I doubt that your PA will work with this microphone. It requires phantom power and 1/4 inputs do not allow for phantom power.


    Does the PRO 42 have RFI suppresion? In a courtroom we are having trouble with radio frequency interference (RFI) using a small boundary mic. The security personnel use radios in the 154 - 159 MHz range. Is the Pro 42 a good choice for this application?


    Unfortunately, the PRO 42 does not have RFI immunity. However, I do not think you would experience any RFI issues because I have NEVER heard of any RFI issues regarding the PRO 42 (there are also no reported issues in our database). If you decide to purchase and you for some reason are experiencing RF issues, there is a Shure product called the A15RF. For more information regarding that product, please contact Shure Inc.

    micing an audience I want to find the most effective mics to use for micing a church audience. I want to try to eliminate room noise from the choir, musicians, preacher, monitors and FOH Speakers. Would this mic be effective in eliminating room noise or should I use a shotgun mic?


    For audience response there are several good mics. You will nee a long throw [shotgun] mic if you have a crowd and can't mic small groups [2-4]. One great way is to hang shotgun mics from the ceiling [as with a choir mic] you'll have to mic each section. The following is a list of good mics to use.

    Thank you for your inquiry. This microphone will work in this application. The rear of the microphone rejects sound, so place the microphone with the rear facing the FOH speakers..
