For Sale Audio Technica M2 Wireless IEM system. Includes transmitter, receiver, and power supply (no earphones). I bought this system in 2016 for a band I did some sub work for that has since disbanded. My own bands are still using wedges so this system is not being used. It is near mint and was only used twice by me. I can usually ship within 24 hours. This unit operates on M band 614.000 to 647.000MHz. Last year "Congress authorized the FCC to use incentive auctions as a means to free up spectrum in the 600 MHz band for wireless broadband use." You can read more about that at: 600 MHz Wireless FAQs || Audio-Technica US According to Audio Technica at the link above, "Depending on your location, you may be able to use your 600 MHz system until summer of 2020." However in Canada, the 600MHz band has not yet been auctioned and will not until at least 2019 according to this article from August 2017: Minister of Innovation proposes 'competitive measures' for 600MHz wireless spectrum auction In light of all this, I am selling the M2 at a drastically reduced price. I recently tested the unit at home and it worked flawlessly and without interference (I live 35 miles south west of Chicago). However, depending on their location, I cannot guarantee the same for the buyer. Sorry, all sales are final. Audio Technica is offering a $90 rebate for the M2 if you purchase a new system by March 31, 2019. So, in theory you could buy this one, use it for a year then trade it in for a new system and get most of the cost of this one back. Something to consider. Details on the rebate program are here: 600 MHz Trade-In Rebate Program - up to $450 trade-in rebate available || Audio-Technica US Asking $100 shipped in the continental US and Canada. Canadian buyers, please add an additional $15 for shipping. Sorry no trades, PayPal only.
