Jeff Rowland with Rel sub

I have a similar situation that didn't work out very well for me. I have a Storm III and have been using it for a couple years attached to an Odyssey Stratos amp with good results. I picked up an H20 S250 amp, which is one of the new digital ICE based amps and is also supposedly a balanced amp. Here's my horror story. I hooked everything up just like the manual said, I'm positive (I think ) I double and triple checked the three sub wires that go to the amp. When I turned the amp on I got a loud noice, something started humming and I smelled fried electronics. In a panic I powered everything back off. Luckily it was my sub that "fried" and not my speakers. The sub is unhooked from the amp, but has a loud audible hum when I turn it on. I've been too busy to follow up with Sumiko and Henry Ho to see if I did something wrong. I'm sharing this with you because both of our amps are supposedly balanced digital amps and like yo u mine worked like a champ before. FWIW, the H20 amp has two sets of speaker outputs. I had my biwired pair on the top set of posts and the REL on the bottom set and they were not touching each other.

I got noise(pop) and hum, but nothing fried. I am hooking to the speaker terminals as per instructions in the owners manual.

When connecting a REL to a differential amp using the high level input (the best choice for 2 channel music) you must ground one of the positive wires of the the supplied Neutrix connector to the amplifier. I believe the configuration is red positive to ground, yellow positive to positive amplifier speaker terminal and black to the negative amplifier speaker terminal for the same chanel (either left or right) you have chosen to connect the positive lead to. Double check the configuration; it should be in the owner's manual. Not sure if the Rowland is a differential, but I hope this info can help aleviate problems people may have hooking up their RELs

Its not clear to me how you're connecting, but I'll comment on what works for me...

With my Ayre V-5x (balanced differential), I use the high-level unbalanced input on the REL. I connect the yellow wire to Left+, the red wire to Right+, and the black wire to a chassis ground screw on the amp.

How are you connecting?

I connected according to the directions in the owner's manual: FIG 2 unbalanced high level input at the sub. To the amp: red to right positive, black to right negative and yellow to left positive. Todster, I tried your suggestion and got nothing.
