Hi @Peter P., Actually, the short lengths of 14-gauge speaker wire I made first went into the pinch connectors on the Russound, and the other end of the wires I threaded through the back of the banana plug posts, which screw in and out. I believe the wires are making good contact; however, I have purchased horseshoes connectors which I plan to use instead of threading the the ends of the speaker wires into the holes the banana plug posts at the back of the Reisong A10 amp. I think doing so will assure I’m getting the best connection possible, and faster connection should I have to unplug the Russound adapter. Thanks again for your guidance.

Hello @Peter P. Thank you for your input (pun intended). It’s decadent to have two subwoofers, and ultimately unnecessary, so I’ll connect the Russound ADP 1.2 Interface as you suggested, using one subwoofer. I’ll use the other one elsewhere in the house, on a different system. By the way, @Peter P., what is an LFE input? Again, huge knowledge gaps I need to fill if I want to claim this to be my hobbie (audiophilia) Thanks in advance

Hi again @Peter P., Thank you for your explanation of phase. I’m an audiophile wannabe in training 😂 Seriously, it’s good to compile such knowledge. Guess what?! I did it! Everything is working now. I simply fed the +/- wires that I connected to the Russound ADP 1.2 Interface into the holes in the back of the banana plug connectors on the back of the Reisong A10 tube amp. There they share the same 8 ohm connectors with the banana plugs for the speakers. As a bonus, I was able to run TWO powered subs! I realized that the Klipsch (R-12SW) subwoofer is of course mono, so it only needs one of the Russound’s two RCA ports. So, with the second RCA available, I plugged in my smaller Jamo S 808 subwoofer, and no surprise, both subs are throbbing away. Playing with phase settings, and using the tricks you taught me, I’ll get this system in synch, in phase. It sounds so good already. That Reisong amp, btw, is absolutely amazing for the price. Thank you again, @Peter P. Attached is a photo of the way I have the Russound rigged up now. I plan to encase it in a housing I bought for it, but have to modify. One more question @Peter P.: do you happen to know if what I’m doing (i.e. attaching multiple speakers to my amp’s limited connectors) is kosher? Or is there a better way to manage my multiple connections? In fact, I’m planning to run two more (Klipsch ceiling mounted) speakers to those two already busy 8 ohm connectors on the back of the Reisong. Much thanks, Mike

Hi @Peter P., Thank you for your quick response. To answer your questions: 1) I’m too novice to know what “in phase” or “out of phase” means, exactly. The Klipsch R-12SW subwoofer has a phase switch, and I toggled that switch while having the sub and speakers connected. The sub thumped 2-3 times but did not respond to the music played. The Russound ADP-1.2 is brand new and is a quality build. I suppose it may have been built incorrectly, but I have no way of determining that. 2) I will try your idea of reversing the inputs. Thank you. 3) The sub is definitely plugged in and switched on. And yeah, the gain is cranked to max. Yes, the sub most definitely works; tried it with my solid state amp. @Peter P. ,thank you again. I’m going to fiddle with this a bit more. If you don’t mind, I will send photos of the setup. That way you can truly see what’s going on. Mike

I tried connecting my Klipsch subwoofer (R-12SW) to my Reisong A10 tube amp, basically the same setup as @JohnZ above, using a Russound ADP-1.2 Speaker-Level to Line-Level Interface. I tried connecting an L/R RCA male to an L/R RCA male cable to the subwoofer L/R RCA female in port. On the other end of the RCA cable, I plugged in the male end into the Russound ADP-1.2 Interface’s RCA L/R female in plug. I used 16-gauge speaker wire to connect to the 4-connector on the Russound Interface, and then connected the speaker wires to the back of the Reisong A10 amp using the only available banana plugs; I put the wires into the 4om banana plug ports. I got a little base response from the Klipsch subwoofer, but it was short lived. Could anyone please tell me what I’m doing wrong? Thank you!

In the end, did this adapter work? I have the same amp and same subwoofer. If you would, please tell me how you set this up. How did you mount the adapter?
