  • Q & A

    I have an ATW-T201 receiver and a Freeway 200 Series body pak. I need to replace the microphone. Is the AT831cW compatible?


    Yes it is. You may use any wireless microphone that ends in the code "cW" which indicates the cable properly terminates with the 4 pin push locking connection used on your Audio-Technica "cW Style" beltpack transmitter.


    Dear A-T, what is the difference between AT831aW and AT831cW?


    The "AT831aW" is not a model number from us the manufacturer. The "cW" code indicates the cable terminates with the "cW-Style" push locking connector to use with cW-Style wireless transmitter.


    Is the clip on part available for sale. The mic works fine the clip and screw has fallen off


    Yes and compatible accessories that will work with the AT831 model microphones may be found here:


    Is this a stock part, or would there be a lead time? How many are generally in stock?


    Thank you for your inquiry. This is generally available.


    I need a replacement mic, chord and connector for our audio-technica lavalier model ATW-T51. FCC ID: JFZT51.


    The AT831cW Lavalier Microphone is compatible with the ATW-T51 bodypack Transmitter. The "cW" in the model number indicates that the connector on the mic cord is the 4-pin female locking (push-pull) type connector.


    does this microphone work with unipak transmitter ATW-T701 and receiver ATW-R700?


    Yes, you may use any wireless microphone that ends in the code "cW" which indicates the cable properly terminates with the 4 pin HRS connection used on your Audio-Technica UniPak transmitter.


    Does the AT831cW fit the McCormick's flute mic mount? I'm worried about the diameter of the mic being too big for the mount.


    The AT831cW is 0.40" (10.2 mm) in diameter. I do not seem to be able to find exact dimensions the listed mount will accommodate. You may confirm with that manufacture that it will accommodate the above diameter.
