Hi, I have 1 svs pc-ultra, the other will be here in about a week. I just got this sub and the sms-1, and only have about 2 hours of use on it. Kids and work keep me away from the tweeking but I get the house to myself on my lunch hour.

Read this forum and learnt how to turn off the sms-1 crossover by remote reset GREAT! I was getting a huge dip at 80, but I also have another at 100.I have a klipsch RF-7 mains. With yamaha rxv-757 receiver, yamaha xover set at 80. I set Xover to off on sms-1 tonight and I'll re-check again tomorrow. Also by reading in this forum I have a better idea of what to do with the volume settings. I have many more questions, but I need time with the sms-1 before I go asking a bunch of how do I stuff.

Happy to see a dedicated spot for discussion on the sms-1. I'll be back!!!

Come on back, HTADDICT - the SMS-1 is a really cool product, but there is definitely a learning curve due to the amount of flexibility it offers.

The learning curve is only steep at first....I hope, I get such little time to do setup, here's the problem I'm having, I'm getting readings down into 20hz and above with my klipsch rf-7's, I'm in stereo mode, all speakers set to small, crossover set at 80hz, sms-1 crossover off. Sub set for lfe output. Just to make sure it wasn't my sub, I shut it off, it's my rf-7's that don't seem to be responding to the 80hz cutoff. Shouldn't the graph be starting around 80hz like in the manual?

The curve can be steep, but if you can get past it the basic operation is pretty straightforward.

So your mains are reproducing a signal all the way down to 20Hz? With speakers set to small, receiver set to stereo but not any sort of bypass mode (stereo bypass would cause the receiver to skip bass management), SMS-1 crossover off, and with the SMS-1 muted (or the sub off) you should see the response drop off obviously at 80Hz. I don't know much about your particular receiver, but I'd suggest checking that it is not in any sort of "bypass" mode.

Ok, I give up... my mains are definently putting out sound down to 20hz up to full strength db level by the time it hits 40hz when set to small. When set to large they start at 15hz to full db strength by the time it hits 30hz. I've set the crossover anywhere from 40hz all the way up to 200 hz in 10hz increments on the receiver to no avail! When I set it to 40 hz I can hear fluttering in the tweets. I've tried all of my dsp modes, pure direct mode, 2 channel mode, straight mode, nothing seems to make a difference, it is not cutting off the low frequencies anywhere near the 80hz like I would like it to. I emailed yamaha last friday but have yet to hear back. Kinda hard to blend in the sub when I have 2 mains that are acting like one.

It sounds almost as if you are stuck in some sort of analog bypass mode. That's odd.

HI HTaddict, just my two cents have you tried resetting everything to the defaults in the yamaha, and starting over, I had a htr series that was kind of buggy like that

Loopy, I think that is what I'm going to try next is just to reset everything, I wonder if the ypaq is the thing that is kinda screwy. Maybe if I reset it and do everything by hand I'll have better results, and if that doesn't do it, I'm wondering if my yamaha is haveing some kind of bass management problem and maybe I'm not the only one. I am new to yamaha since I've only owned sony ES's in the past so I'm trying to get used to the different setups so there might still be room for some user error, but at this point I doubt it. I'm going to try putting in another e'mail to yamaha.

Typically when you guys set your xover, how quickly does it flatline behind your set-point?

If my memory serves correctly, the response curve had a small curve starting right around the crossover point and then a line probably running at a 45 degree angle, but I could be remembering the angle of the line wrong. It's a noticeable event, though.

Well, I went in and reset my receiver and tried manually setting things = no change. still same response, then I tried the auto setup, same thing. For all I know it is the yamaha that is not initializing the crossover. Still rapid climb at 25hz. Next thing is trying to find out who to call, Yamaha or Velodyne? It is a yamaha problem but I wonder if Velodyne could help me out too, you wouldn't think that there was a problem with the sms-1? It seems to be working fine.

I don't see a way for a problem at the SMS-1 to yield the results you are seeing unless the curve and the test tone obviously differed, which would be a mighty weird scenario. I'd probably start working through the Yamaha channels just for the sake of being thorough, but Velodyne or even Outlaw might be able to chip in a few suggestions.

I called Yamaha tech support today, I got a quick response from a friendly tech, but alas he confirmed that my settings were correct and that any signal below 80hz should be redirected to the sub.

I'm sure not many people have dual svs-ultra's, and a velodyne sms-1 and six Klipsch RF-7's in there system so it would be hard for a tech over the phone to say it was the yamaha's fault. I sympathize with the fact that it would be hard for yamaha to fix my problem due to the fact that I am using a velodyne product to measure things, I guess the next step is to try a different receiver and see if that responds correctly to eliminate the sms-1 (although I'm pretty sure it's the yamaha). Other than getting a different receiver I don't see how I'm going to stop my mains from being at least in some part "full range" and anything I gain with the velodyne sms-1 will be negated when I have six RF-7's throwing bass all over the place.

You guys at outlaw must be pretty lucky, I don't know where to go with this problem, other than fix it myself by buying another new receiver, I do not want to stick my dealer with this one as I like the relationship I have with him now and don't want to strain it for such a small thing. But I do want it fixed, I didn't spend all this money just to be tripped at the finish line. I've been holding out on a pre-pro due to the fact that I've been buying tons of other stuff, and that they don't have quite the features I want yet (not that the rxv-757 did, it was just a temporary fix).

I think the yamaha has a problem with bass mangement but I don't expect them to admit it.
Time will tell I guess, and if I'm wrong I will have no problem admitting that. I'll try my best on this end to clear up any user error. Sadly what I thought would be easy is turning out not to be.

If you've got a good relationship with your Yamaha dealer, I'd suggest taking your SMS-1 and mic into his store and giving it a whirl on some other gear there - Yamaha and/or another brand. I suspect the "geeky gadget" appeal of the SMS-1 will help make the experiment appealing to him, and he might be able to help you with the receiver without getting himself stuck.

Sounds like a logical idea, thanks gonk. Solid advice through and through! I imagine they might like to get to toy around with it, I bought both the receiver and the sms-1 from them and they seemd pretty interested when it came in. I never even thought of takeing that approach. Maybe if they get interesteded in it, I might get my problem fixed also. I'll post results after I get it set up if the are game for it.

Thanks for all the help from everyone here, and Gonk....you da man!

If they sold you the SMS-1, I'd have absolutely no qualms about going back to the store with your unit and giving it a spin - they ought to be quite agreeable to tucking it into a demo room for a bit, and if they haven't played with one before I suspect they'd enjoy it once you got things rolling. Glad I could help.
