The only pictures I can find of it have a TRS (stereo) 1/4inch. Looks like that's how it gets it's power from the transmitter. Makes me wonder if some guitar wireless system like a line 6 might work?I have been using the Shure PGX system for over 15 years and use mine with the SDSystems LDM-94. As long as your LCM89 has the Shure 5-pin mini plug it will work with any Shure system. The PGX is the most economical and I have had no problems with it in all these years.
