Well as I noted, there is no published output voltage for your Elite (at least not in the manual), so it’s hard to say for certain. The 2500 requires 1.09 vRMS; you’re probably safe with that one. The 3500 requires 1.23 vRMS; that may be okay as well. There’s a good chance you’d need a signal booster for the 5000 and 7000
