Also have the same problem. Have Vitus RI-101 mk2 and looking at getting a REL sub. Vitus site says NOT to use the speaker connections and only the the pre-outs. I was even having trouble hooking it up to a sub with only rca inputs. Had to have blue jeans cables make custom sub cables for me. XLR->RCA with 10k ohm resistors on pin 2 if I remember correctly. Their disclaimer made me so nervous to hook up my sub I never did even though I bought custom cables. I did not want to damage the amp since it's so costly. I emailed Vitus trying to get some answers and they were not very helpful. Please let me know how you hooked up you REL if you ever did. Thanks!
Vitus RI-100 And REL G2 Sub Wiring Experience?
Any comments or advice from current Vitus RI-100 Integrated Amp owners who are using it with REL G2 subs or any REL subs for that matter - even past models like the Stentor and Studio? This would be a two channel only two subwoofer configuration using the high level neutrik connection from the sub to the amp speaker terminals and/or the chassis. Its not clear if the RI-100 is differential or standard or some kind of hybrid - thats why some real experience with successful results would be very helpful.
