  • Home Audio Receiver to Pro Amp connect

    I want to hope up my receiver to my iNuke 3000 pro amp, so far I used an ART clean pro but can only get very low volume from my sub so I tried it on my tower speakers with the same result, barely any volume. I read about it being done all the time but can't figure out how.
    I've tried everything I can think of, different receivers,connections etc. I'm going nuts...more than usual!

    What do you/others use to get receiver to pro amp work

    The ART should do the job converting from unbalanced to balanced. It must also increase the level of the signal. Are the ART level controls set to max?

      It should work without the cleanbox, it can take balanced or unbalanced input. Set the mode switch to stereo. Set the crossover switch to full range. Use a RCA to 1/4 TS cable, that will short the Ring to the sleeve for an unbalanced input. Check your Speakon connectors. It's very easy to get the connections between speaker one and speaker two messed up, swapping 1- and 2-, been there- done that.

        Consumer line levels run around -10dBu, pro sound +4dBu, so that's 14dB of gain you'd need to come up with between the receiver sub out and the amp line in.

          The ART clean box only routes:
          RCA >>> XLR or XLR >>> RCA

          It does not pass
          RCA >>> RCA or XLR >>> XLR

          So, if you are using a passive RCA to XLR adapter, then plugging it into the XLR input on the clean box, you won't get XLR out (if that makes sense.)

          I don't know if that's your issue, but I made the same mistake with mine ;)

            That's usually the spec for typical inputs, output levels can vary widely. But based on the fact the OP said subwoofer output, I'm going to guess that his AVR is going to be able to put out at least 0dBu. Has any AVR made in the last 20 years not had a "hot" subwoofer output? But even at -10dBu he should have more than "barely any volume"

            To the OP - what kind of AVR are you using? And have you tried resetting it back to factory?

              Good info. Chris, the OP should provide a connection drawing or pic. devnull has a point though lots of things in the chain from source to output can add to the issue.

                I used the Rolls Promatch for my Crown XLX2002 and it converts rca to XLR. Even though the crown has a higher input sensitivity setting for consumer level components its still wasn't a enough gain. With the Rolls I can crush the analog signal to almost full and my amp gains are at 40 percent and I have huge output without clipping.

                  While I think post Chad1367's post #7 is the answer, I had low sub-woofer volumes when one occasion where the receiver was rolling off/high pass the low frequencies (small speaker setting) thereby reducing the bass output, then another time when I use the crown's low pass filter in conjunction with the receivers LFE signal.

                    Just to make it more clear, below is from the owner's manual.. This is also printed on the bottom of the clean box. It's two completely separate circuits stuffed in one case (maybe there's some cross-talk passing a little of the signal between the two?) I don't think OP ever came back to look at this thread though.

                      Thanks guys but still having issues Sorry for not getting back I was out of town on an unsuccessful Big Foot hunt. A guy on the internet swears he has seen one, maybe even 2!

                      I'm using a Yamaha RX-V380 - RCA Subwoofer out, to ART Clean Box unbalanced RCA; then using a XLR 3 prong to 1/4" male to connect to amp; from the amp I'm using SpeakOn cable/connectors But still no luck, if I get any sound its very weak. The Yamaha is brand new bc. I dropped my Yamaha RX-V685 while pulling on a cable and now it has x5, .50 cal holes in it...I'm not even going to ask if the warranty will cover it

                      In case anyone was worried my house is all 10"-8"+ ICF construction, so none of the 5, 460 grain projectiles penetrate the garage walls. I just got yelled out by the wife again about not shooting in the house, blah blah blah... "No shooting In the House!" Yes dear. Anyone else "not" allowed to shoot, ride motorcycles, set off fireworks or have Mexican cartel leaders over for cock fights in your living room or is my chick just super uptight?

                      Any help or better yet help with photo's would, be of great help. Thanks guys

                        Is that a 2 or 3 conductor 1/4"? If it's is only 2 conductor you are losing some gain and if it isn't wired correctly you are losing all of the signal. Why don't you try an XLR to XLR cable.

                          That is what I was about to suggest. I, too, have done this.

                          I havent had had to use an art clean box with my Crown XLS but noticed what seemed like less output at the same level when I had an iNuke. I’ve run a Yamaha for years and the sub output seems potent enough for a pro amp.

                          A question for the gallery - would a miniDSP cleanly boost the signal to a sufficient level? Seems like it would be a better solution for a bit more change than the art box or Rolls when you don’t need XLR.

                          As for gunshots in the house... my wife draws the line at Tannerite. Bullet holes are easy to patch, gunshot noise can be blamed on the speakers, but shrapnel from tannerite is harder to clean up...

                              You're not allowed to shoot Sasquaches any more, after legislation passed in 2018 they're strictly catch and release.
