  • Q & A

    wireless microphone only


    Thank you for your inquiry. This system has been discontinued.


    My church used a Audo-technica System 8 (T2) wireless system for a number of years and now maintains it as a back-up for our main system. In the past we were able to use either a head worn microphone or a handheld microphone on the same receiver. (This was an either/or situation not both at the same time.) The handheld microphone has gotten misplaced. Is it possible to get a replacement or another model that would be compatible?


    Yes, you may use the System 9 transmitters which have 4 selectable frequencies, one of which is the same T2 frequency on your System 8.


    I need to replace the handheld mike from our ATW-T801-T2 system -- it grew legs and walked away(: Are replacement mikes still available and if not, are there others that will work with this system?


    Thank you for your inquiry. The ATW-902a transmitter will work with this system.


    How do I register my wireless mic ? S/N 15351975 ( ATW-R800-T8 )



    I use this for teaching aerobic outside. I get static after about 30 minutes. Why?


    Thank you for your inquiry. Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    I need 5 wireless mic. can I order 5 and use them all at the same time without interference or worrying about frequency's ? Thanks, Doug Kieser


    Thank you for your inquiry. Yes you can use 5 at the same time as long as each mic being used has its own receiver as well. 5 mics will need 5 receivers.


    Hello, I'd like to split the audio output of the receiver so I it can be sent to two different devices (two computers). I found the a "Y-adapter" that says it is for mono applications and uses a TSF tips. Are TSF tips the correct ones to use? Thanks!


    Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    Is this compatible with a Powerwerks PW50 speaker?


    Yes, it looks like the system you listed will have the proper inputs to plug the System 8 receiver into.


    Can the microphone select different frequencies? I have an audio-technica PRO 88W/T wireless microphone transmitter and receiver. The receiver can operate on two frequencies: 169.505 and 170.305. I noticed that the Audio-Technica ATW-T802 VHF Wireless Handheld Transmitter operates on the 169.505 frequency and several others. Can that microphone work with the PRO 88 W/T? If not, I have a wireless receiver that works with the other frequencies and would like to know if the microphone can change channels. Thanks,


    No. With wireless systems, it is common practice that you will need to use the matching transmitter with the receiver.


    Hello, I bought this system with a lavalier microphone. However, the microphone wire broke after a few month of normal usage. Is it covered by warranty? Best regards.
