My HS has two Sennheiser Evolution Wireless G2 systems, and two First Gen systems. One of our first-gen wireless transmitters is on the fritz, and we can't get it repaired. Ebay is not an option here, as it is through the school system. Since the first-gen series has been discontinued, only the G2 series is available through our normal contract dealer. The Question: Will a G2 beltpack work with a G1 receiver (if both are on the same freq, of course)??? I'm guessing no, but it's worth a shot. Thanks!
