  • Q & A

    Hi. I was curious if there is a way to convert this to a wired mic that could go straight into a mixer. Thanks!


    You may use the AT8539 power module which needs to be inline for a wired connection.


    Is this mic compatible with the System 10 series beltpack transmitter?


    Thank you for your inquiry. Yes this will plug into the system 10 belt pack.


    Will this work with my System 10 Pro wireless body pack?


    Thank you for your inquiry. Yes this will plug into your system 10 body pack.


    I have 3 pro 35 horn mics and I need replacement wind screens. Where can they be purchased?


    To receive an answer to your question, please contact the Audio-Technica United States (ATUS) Audio Solutions Team at: Sometimes, the customer is referring to the windscreen for the AT8418 instrument mount. Please let us know if this is the case. Thanks!


    Is it possible to power the ATM350cW with the AT8801 Phantom Power Supply without the AT8539 Power Module in the chain? In this case I would replace the 4 Pin connector with a standard XLR connector. So I guess my question is whether or not the AT8801 sends the correct Phantom Power for the microphone. Thanks!


    To convert the ATM350cW into a wired microphone for XLR use, one would need the AT8539 Power Module and a Phantom Power source (such as an Audio Mixer that supplies 11 - 52v Phantom, or a dedicated Phantom Power Supply like the AT8801). The power module is necessary; do not cut the connector and go XLR direct, as that will void the warranty, and cause permanent damage to the microphone. If you have any further questions, please contact the Audio-Technica United States (ATUS) Audio Solutions Team at: Thanks!


    Is the ATM350CW shipped with the violin mount included, like the ATM350 version or must a separate violin mount be purchased?


    The AT8468 Velcro Violin Mount does ship with the ATM350cW as well.


    ATM350 vs ATM350cW Is the actual microphone element of the 350cW the same as the 350? What accounts for the difference in price?


    Yes, they are the same element. The ATM350 is a wired microphone. The output connector is a standard balanced 3-pin XLR male type connector, and it is designed to be connected to a balanced XLR microphone input with phantom power on it. The ATM350cW is the wireless version of the mic. The output connector is a 4-pin female Hirose type connector, and it is designed to be connected to our UniPak model bodypack transmitters. Power is supplied by the transmitter in the form of a low bias voltage. The wired ATM350 uses an inline power module to convert phantom power to bias voltage, balance the output, and set the output impedance. The requirement of the power module adds to the cost of the ATM350 wired microphone.


    compatibility with other beltpacks i already have a wireless system with beltpack transmitters that is not AT. is it possible for me to use the ATM350cW with the gear i already have? are there adapters or wiring schemes for the connectors available?


    We do not make adapters for this purpose. Depending on the particular make and model wireless system you will be using the ATM350cW microphone with, it may be possible for you to re-wire the microphone to the appropriate mating connector for that system. Please contact our Audio Solutions Department at (330) 686-2600 x 5000 or with the make and model of your wireless system for further assistance.


    Specifically, will this microphone and transmitter work with the ATW-R09?


    Any of our microphones for wireless whose model number contains the letters "cW" are compatible with our UniPak (4-pin Hirose connector) model Transmitters. The ATW-T51 Transmitter is such a model.


    Our church was donated a ATM350cW that has been modified with a XLR plug for one of our horn players to use. When I plug it into our soundsystem I only get a faint signal. I am using the fantom power. I even tried a preamp, but got too much noise. Any suggestions on how to increase the signal.


    Thank you for your inquiry. The connector cannot simply be replaced with an XLR connector. A power module must be used to convert the phantom power to the proper voltage needed by the mic. If the microphone is sent phantom power without the power module there is a good chance the microphone will be damaged.
