    How does it connect to receiver/mixer

    How does this connect to receiver/mixer? Does this has a XLR std size to connect to wire to connect to receiver?

    Answer: 
    The BP892 and BP892-TH feature a 4-Pin HRS connection for use with Audio-Technica wireless systems, AND comes with the AT8539 Power Module for use as a WIRED MICROPHONE. The included AT8539 features an XLR connection, and requires Phantom Power for operation. The included POWER MODULE is IMPORTANT for wired use, as it balances the microphone's output, and steps-down the standard Phantom Power voltage down to Bias Voltage, to meet the microphone's power requirement. The -TH means the microphone is Beige. If there is no -TH designation, the microphone is Black.

    Since the BP892 and BP892-TH are ultimately WIRED microphones, if you are looking for dedicated wireless versions, those model numbers are listed below:

    Wired Versions of the BP892:
    - BP892 (black)
    - BP892-TH (beige)

    Wireless Versions of the BP892, connects to the following transmitters:
    - BP892cW* (Audio-Technica 4-Pin HRS Wireless Systems)
    - BP892cT5* (Lectrosonics wireless systems)
    - BP892cT4* (Shure wireless systems)
    - BP892cLM3* (Sennheiser 3.5mm wireless systems)
    - BP892cL4* (Sennheiser Lemo wireless systems)

    *All are available in a -TH version.

    If you have any further questions, please contact the Audio-Technica Audio Solutions Team at audio-solutions@atus.com .

    BP894 boom length

    Hi, we bought this mic late last year when it came out to the market. We are pretty happy with the audio performance. But one thing that is an issue is the length of the boom. With this mic, the boom is relatively longer than our previous head worn mic, and we can't figure out a good method of shortening. As it is, it is too close to the pastors' mouth and nose, and we are getting too much plosives. with the cardiord behavior the low-end of the plosives are extremely powerful. We tried to bend the ear clip end of the boom straight down, and then bend the boom back up, effectively shortening the boom. But still it is not short enough, and unable to get the mic head back toward to cheek area. If there is a better method, or a way to shorten the boom, please let us know. The foam screen seems to help some but we have not been able to verify that it helps consistently. We have different pastors using this mic and the mic responds to each pastor's plosives differently... We have not try to twist T-shape head yet, that is the next thing to try. Thank you.

    Answer: 
    Thank you for your inquiry. I ran into this with the microphone I put on my pastor. Being a cardioid pick up pattern the mic has proximity effect which can manifest itself in plosives. With my pastors mic we, put a slight "Z" bend in the boom to shorten it. Be extremely careful in doing this so that you do not break the boom. You can also take out a bit of the low end at the board which can take out some of the plosives.
