Q:BP894 boom length
A: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.
Q:How does it connect to receiver/mixer
A: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.
