Thank you for your inquiry. Yes, this will work with the wireless system, but please note the following information.
The FCC auctioned off the 700 MHz frequency spectrum to cell phone companies and has ruled that wireless microphones can no longer operate in that spectrum as of June 2010. These systems are in the 700 MHz spectrum and were affected by the auction. The FCC has also ruled that companies cannot sell or service any wireless microphones in the 700 MHz spectrum.
I regret to say there is no "re-crystal" option for any of the discontinued 700 MHz A-T wireless. Our wireless are either crystal controlled (single frequency wireless) or frequency agile (phase locked loop multiple frequency capable wireless) designed to operate within a specific frequency spectrum. The RF spectrum capability of the wireless is determined by frequency specific components. Our crystal controlled wireless could be frequency changed within the band they were designed to operate in, but it is not possible to change either crystal controlled or frequency agile wireless out of the spectrum band they were designed to operate within.
We offered a rebate program for our 700 MHz customers for about 2 years, but this program ended in June of 2010.
