Heat heat and more heat??

You're welcome! Pin 1 on the XLR connectors would also be a circuit ground point. Perhaps a convenient means of making use of that would be to obtain an XLR-to-RCA adapter, such as this one, inserting it into one of the unused XLR inputs, connecting the black wire to the ground sleeve connection point of an RCA plug as I described, and inserting the RCA plug into the adapter.

That and most such XLR-to-RCA adapters will connect the RCA ground sleeve to XLR pin 3 as well as to pin 1, but I'm pretty certain that won't matter in this case.

Correction to my previous post. When I said:

... upon looking at the manual for the 8T (I couldn't find one for the 8) I see on page 8 a statement that "When the RCA position is selected, pin 2 of the XLR input is shorted to pin 1." That is unusual, as in most cases involving USA equipment if any of the two signal pins on the XLR connector were grounded when the RCA input is being used it would be pin 3.

Given that, I suspect that the center conductor of the RCA connector is connected internally to XLR pin 3, so using an XLR-to-RCA adapter which connects pin 3 as well as pin 1 to the RCA ground sleeve would kill the input signal on the RCA connector.

I believe that Cardas can supply, at least on special order, XLR(male)-to-RCA(female) adapters that do not ground pin 3. Those would be suitable.

But surely there must be some screws on the case of the amp to which you could attach the wire?

Hi Al, I have looked at the back of the amp, all of the screws are recessed and seem to have a specific job regarding the amp structure. ( I am concerned that loosening any of them could be problematical as to what they are connected to inside the casing). I will see if Cardas does offer this kind of adapter...hopefully,it would solve the problem. I am also planning on contacting the factory as the amp still runs hot ( I am concerned I have damaged a resistor, as you have stated). ( Although the sound seems to be ok). I will also ask them what is the hook-up protocol given the balanced aspect to the sub. This is so crazy, and I am kind of annoyed at the dealer who failed to alert me to this issue.
Thanks.

Had a Rowland 8T never had a heat problem in 15 yr.

Dave, rather than using an adapter you might also consider simply purchasing a 3-pin male XLR connector and wiring the one connection (black wire to pin 1) yourself. For one thing, that would undoubtedly be a good deal less expensive than using a Cardas adapter. Parts-Express.com has lots of choices of suitable connectors, costing just a few dollars.

Good luck. Regards,
