Q:I tried to unscrew the power module to insert the battery - but the middle of the module is not moving. Do I have to take out the screw at the top of the module first or take any other action to loosen it?
A:Thank you for your inquiry. You do not have to remove a screw. Unscrew the base of the power supply unit and insert one AA battery into the battery compartment, being certain to observe battery polarity as marked. Then simply screw the base shut. If you still cannot open the battery compartment it may be on cross threaded and you will need to contact our Service Department at 330-686-2600 option 4. They will be happy to help with this.
Q:How do I change the battery on at8537
Q:The 8537 module is quite long, and would exert a lot of leverage on my mixer input jacks. The mixer supplies phantom power, so is there a version of this which does not have a battery?
A:The AT8538 Power Module (which is a phantom only power module) will work with the AT898 and AT899, but Max SPL might change.
Q:Does this module provide "plug-in power"?
A:No. Power Modules are used in conjunction with Audio-Technica microphones to regulate power and incorporate other features.
Q:Adaptor cable for mic AT899
A:There is a 4-pin Hirose type connector that is for use with our UniPak model bodypack transmitter wireless systems, as well as a 4-pin TA4F type connector that is for use with Shure brand wireless systems.
Q:Need Pin out diagram for at8537
A:The pin-out for the TB3M input connector is as follows.
Q:How to get power to work
A:Thank you for your inquiry. Please note that in your configuration you must have the battery installed. Also, you must be going into a microphone level input. If the input is line level the volume will be very low and noisy. Please note that all Mac computers have line level inputs. The battery life for this power module is 1200 hours typical (alkaline).
Q:How can I use the AT8537 Power Modeule with a Pro 88W?
A:The AT899 is not compatible with the PRO 88W. As an alternative, I recommend purchasing the MT830mW.
A:The "straight" line = normal frequency response.
Q:Is AT8537 power module needed when using external phantom power?
A:Thank you for your inquiry. The power module attached to some condenser microphones provides several important functions. First, it converts the 11 – 52 VDC phantom power into a smaller DC bias voltage used to power the FET impedance matching circuit inside the microphone. Also, it provides low frequency roll off, supplies battery power if phantom power is not available, converts the signal to the proper impedance and balances the output. The power module is a necessary component.
