  • Overview

    Audio-Technica’s advanced M3 IEM system offers a full range of professional in-ear monitoring features, with a choice of 1321 UHF channels and easy-to-read LCD information displays on both transmitter and receiver for setting preferences. The stereo monitor system is equipped with Audio-Technica’s versatile Personal Mix Control, which allows volume and mix control of two independent signals on stage, via controls on the M3R stereo body-pack receiver. While up to 16 complete M3 systems may be used simultaneously, any number of M3R stereo receivers can operate on the same frequency with a single M3T stereo transmitter. The M3T Stereo Transmitter is equipped with two XLR/¼” combo input connectors into which users can connect line-level inputs (from a mixing console, for example). The M3T also offers a headphone output that allows you to monitor transmitter input signals directly.

    Background professional drummer and I have gone through a variety of vocal stand and floor monitors and have found the m3t has proven to be more reliable. The sound quality and range are very good. The monitor is very easy to set up.

    Great deal, well under a G Note

    I got these from a local dealer hoping that I wouldn't have to pony up for a set of Shure's and so that I wouldn't add to the noise confusion that was occurring already (someone else wanted to add another floor monitor). I found it excessively easy to set up and start using, got my mix set up and shoot vocals to one side and instruments to the other. I have yet to get a set of custom molds, but the included ear tips seem to work just fine at blocking out the ambient noise and allow me to focus on my singing and playing. The unit has more options than I really need, which is weird because I LOVE bells & whistles.

    Reliable and always ready!

    We have used the M3 systems for 4 years now on the road and like them very much. We do not use the supplied ear buds though. We bought Westone ones which we liked better. The four star rating is for the body pack. It's large and bulky and it's really hard to get the batteries in and out of them. They use up batteries a bit faster than your wireless instrument or vocal pack but still go for a good 3-4 hours with rechargeables depending on the outside temp. Over all they are great, rugged and trustworthy systems.

  • Q & A

    I'm not receiving any signal through my receiver. It keeps flashing "unlock" on the receiver display. I have never seen this before in the four years I've had this product. Please help.

    Mike

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

    Brent

    I have been using a set of M3 receivers for about 7 years. A few are starting to have some issues, like cutting out and in randomly. Is it possible to have them refurbished?

    Brad

    Thank you for your inquiry. This sounds like you may be experiencing RF interference from something. Please contact our Audio Solutions Team at 330-686-2600 ext. 5000. They would be happy to help you.

    AudioSolutionsManager

    Is there a way where I can buy just the antenna's for the M3R UHF Stereo Receiver?

    Malachi

    Thank you for your inquiry. You may contact our Parts Department at Parts@atus.com or call (330) 686-2600 ext 5002. to inquire about a replacement if you are located in the US.

    What is the difference between frequ band L and M?

    Mark

    Thank you for your inquiry. The L Band operates in the 575.000 to 608.000 MHz frequency band. The M band operates in the 614.000 to 647.000 MHz frequency band. You will want to make sure the location these are being used in do not have TV channels being used in the same band as your In-ear monitor system, or you will get wireless interference. For assistance in selecting the right frequency band for you in your area, please contact our Audio-Solutions Department at (330)686-2600 ext 5000. or email at Audio-Solutions@atus.com.

    Hi I just bought the m3 wireless IEM System. I am wondering if the rear antenna will work ok mounted in my rack. The rack is a Gator, Polyethylene materiel I believe. The only metal I believe is the locks and the rack holes. If it may be a problem is there a kit for the m3 to front mount the antenna? Thanks

    Jim Byrd

    "Use any number of Stereo Receivers (with individual mixes) on the same frequency" Does that mean I can send 10 individual ques to 10 receiving packs using 1 transmiter?

    Emmanuel

    You are sending a single mix from your mixer to the M3 transmitter. This may be picked up by any number of receivers. (Just like a radio station.) The number of individual mixes you want, you will need that number of transmitters.

    ATUS_Specialist3

    Can you use multiple receivers/body packs with one transmitter?

    Bjorn

    Yes, just like a radio station; the transmitter is sending out a signal and any number of receivers can pick up that signal.

    ATUS_Specialist3

    Is it possible to use the M2R receivers with the M3 transmitter?

    Alexander

    No, the two systems have different pilot tones.

    ATUS_Specialist3

    What size screw is used to mount the rack "ears" to the M3 transmitter body sides. There are three holes on each side and while the unit came with the ears, there did not seem to be any screws included.

    PETER

    Thank you for your inquiry. The size is M3 X 6.

    AudioSolutionsManager

    I have 5 M3T systems. How many aux sends does my Mixer need to give each person personal stereo mix? Do you have diagrams showing how to connect everything? I want to put them in a rack also and carry the rack to different venues and connect to the venues board to avoid having to use floor monitors and the low rent places my group plays. We never got a good monitor mix
