Q:You say the U841A has a low-frequency cutoff filter. How, if at all, can one switch it off?
A:The Low-Frequency cutoff filter is the on the AT8531 power module, which is necessary for use with the U841a. On the power module, there are three settings: off, bent-line, and straight-line. The straight-line means normal frequency response. The bent-line is the Roll-Off, and Off means that the microphone will not pass audio.
Q:Is there a adapter/devise for this Microphone where it can be mounted it to the ceiling?
A:Thank you for your inquiry.
Q:Is the U841a sold as each or by the pair?
Q:Coverage Range of U841A
A:Thank you for your inquiry. As in all things audio the answer to your question is "it depends". It depends on how loud your sound source is verses how loud the background noise is. It depends on how high you can set the gain on your audio system. It depends upon whether the microphone is used for sound reinforcement within the room where it is used or if it is used in video / audio conference or in a recording. Also, very importantly it greatly depends upon the acoustics of the room. All of these factors is one reason it can be a good idea to use an audio consultant or sound contractor when setting up a room and buying equipment.
Q:Is there an alternative microphone for U841A with mic on and off button? I am using this microphone for Cisco C40 codec.
A:Thank you for your inquiry. We have the U891RCx that has a switch, although it has a cardioid element. If you need an omni microphone, you can purchase the UE-O element speparately and replace the element in the mic.
Q:need to connect u841a to mixer desk
A:Thank you for your inquiry. You will need a standard XLRF to XLRM microphone cable. The power module has an XLR male connector. Please note if your mixer provides phantom power, the microphone will use it. If not it will use the on board batery.
