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.

You can unscrew the power module from the middle section. The power module takes (1) AA battery.

The AT8538 Power Module (which is a phantom only power module) will work with the AT898 and AT899, but Max SPL might change. Please keep in mind that the Power Module is necessary for use with the AT898 and AT899 in wired applications: http://blog.audio-technica.com/audio-solutions-question-week-can-remove-power-module-microphone/ If you have any further questions, please contact the Audio-Technica United States (ATUS) Audio Solutions Team at: audio-solutions@atus.com Thanks!

No. Power Modules are used in conjunction with Audio-Technica microphones to regulate power and incorporate other features.

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. For WIRED use however, the microphone is terminated with a 3-pin TA3F (often referred to as mini-xlr) type connector. This connector mates with the TB3M input connector on the AT8537 inline power module. The output connector on the other end of the module is standard size 3-pin XLR male. You need the power module if you are going to be using the mic as a wired mic. The power module may be plugged directly into a standard size 3-pin XLR female MIC input jack on the Mixer or Receorder, or the total length of the cable may be extended by adding a standard XLR female to XLR male microphone cable between the power module and the MIC input jack.

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).

The AT899 is not compatible with the PRO 88W. As an alternative, I recommend purchasing the MT830mW. If you have any further questions, please contact audio-solutions@atus.com. Thanks!

The "straight" line = normal frequency response. The "angled" line = low frequency roll off. The roll-off might be used in environments where there is a lot of unwanted low-end information (i.e. sounds/noise coming from HVAC units). Please see the spec's of your microphone to see where the roll-off occurs.

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.
