Q:One of our AT8538 is broken... I searched for a replacement, but seeing only 8539A. Is this the new replacement for that Phantom Power Module?

Q:Use of AT831r with UniPak transmitter
A:We do not make a converter for doing this. You would be better off with the wireless version of the microphone, the AT831cW, for wireless use and adding our AT8539 Power Module to it if you need the ability to make the mic "wired" again. The AT831cW will have the female 4-pin Hirose connector needed to connect it to our UniPak model bodypack transmitters. The AT8539 Power Module input connector is the same type 4-pin connector that is on the transmitter. Like your current AT8538, the AT8539 Power Module has a standard 3-pin male XLR output connector and requires phantom power to operate.
Q:AT8538 Poswer Module question
A:The AT8538 Power Module for your microphone requires phantom power to operate. Phantom power is NOT passed on the 1/8" jack of your recorder. Phantom power is passed on the 3-pin XLR MIC jack only.
Q:AT8538 with ATM35?
A:The Power Module for the ATM35 is the AT8532, which is available through the ATUS Parts Department (firstname.lastname@example.org).
Q:I would like to use a preamp and EQ device (LR Baggs Gigpro) to have on-stage control of the AT Pro 35 clip on mic (& AT power unit). Will this work?
A:This is not going to work. The PRO 35 requires that a minimum of 11 volts DC phantom power be applied to its AT8538 Power Module to work. Phantom power would need to be applied to the balanced XLR Male output connector on the power module. Note that phantom power is typically applied over a balanced connection. On an XLR type connector, phantom power appears on both pins 2 and 3 of the connector (when each is referenced to ground). The Gigpro does not have a balanced type input. It has a single 1/4" unbalanced type input. You would need to replace the provided AT8538 Power Module with our AT8531 Power Module which can power the microphone via a single AA battery inserted into it. Phantom power would not be required. The output connector on the AT8531 is also a balanced 3-pin XLR Male type connector. It will need to be adapted to the unbalanced 1/4" input on the Gigpro. Use an XLR Female to 1/4" unbalanced male plug cable to do this. Keep the cable length as short as possible as this is an unbalanced line and will be susceptible to the pickup of noise.
Q:Is there a battery in the AT 8538? I am not getting a signal even tho phantom power is on.
A:The AT8538 does not accept a battery.
