Classe Sigma SSP and Rel S3 connection issue

I used both inputs which is recommended by Rel. I have my center and surrounds speaker Xcross over at 60 and 80 hz respectively. Then front left and right set to full. This is what rel recommend but I lost all mid bass. Then I change the front speaker to cross at 60 hz but still have the same results. Rel said this is what need to be done but Classe said no.

My main front left and right are B&W 804s and center is also B&W htm3s. They are cross at 60hz. There are no sub out cross over in the Classe. The Rel speaker level cross over for the main speakers is cross at around 40hz. When I listen to stereo music using just the main with the speaker level input, bass are fine. It is just that for 5.1 listening, even we set all speakers to small and let them cross over to the sub out, the mid bass is not that good. I think is something to do with how Classe handle bass management. Quite disappointed with the Sigma SSP.

I have tried that scenario as well,have all speakers cross at 60hz which mean only the LFE input and sub out are used, but mid bass is still missing. The only way I got full bass is disable sub out at the ssp and set main speaker to full. This way all the other speakers will send their bass info to the main speaker and the rel support the bass under 40 hz. However I don't like this setup because it will put an extra load on my amp. What I don't understand is why I still can't get full bass from the ssp using sub output and the rel LFE input, and have all speakers cross at 60 hz?

Were you using ebass or not
Did you know there were lfe bugs that the newest software corrects, and it corrected issues, what slope are you using as well as mode and 12 or 24, peq and tone ??, if your ssp was a demo check the peq

Just upgraded to the latest firmware last night 1.0.3.14. It doesn't seems to make any difference. I still have no mid bass when enable subwoofer and eBass in the speaker setting. I am using slope of 12, no Peq and no tone. How is your setup? Do you feel u got enough bass ? My Sigma SSP is brand new from Classe not a demo.

Remember Ebass Routes Lfe to the Mains AND the SUB So it might be a cancellation.

No PEQ = check the Checkbox Group enable and the front LR and Sub Groups just to be safe
Under Controls Disable The Tone Controls

Just so we can eliminate a second system issue
Take a second config (Config 2)... set front LR to FULL
Assign a source 2 channel audio.. see if the midbass is there Just by process of elimination, then switch over to config 1, turn Ebass off

60, 

We can take a blank memory stick back the config and reset the prepro (menu 1 2 3) on the remote.. and then see if its something in your config... I suggest its cancellation... And I take it you checked set and measured delays

Notes Config 2 Set everything to off, the mains to full And See what you get with a 2ch source set Just to eliminate other system issues, I have 0 LFE issues

If you PM me I can try and walk you thru it.

Just a Thought if you set to full and No Sub the LFE should be routed thru mains Without needing a second .1 connection as well Could be an issue there if you are using both.

Waaaait what did you set the delays and distances to for the .1 AND the front LR

Can you tell me how do I PM you privately?

I thought I could pm within the system Naplesisnotmyhome@gmail.com

What Amp are u using? Can u also tell  me how do u config your setup. Did u set all speaker to small and croas at what hz? What level u set your sub to? And are u using eBass? I am assuming u are quite happy with the SVS. Did u connect the SVS using the sub out in the Sigma SSP? Thanks.

Citadel 1.5s for the front left and right, running balanced, using a proceed amp5 for my center, surround channels

And my 2ch config is full range under configuration 2 no other speakers enabled

My multi channel config
Mains cross at 40hz -3db at 35
Svs crossed.at 40
Group and eq measured with roomeq wizard
Delays were tape measured

My mains have active subs, so my config is unique and no lack of clean low bass in either config

What do you your rew plots look like and spl readings 75db weighting type c

Roomeq wizard and an spl meter should put you in the right direction to calibrate the ssp 

Hi I just brought an Svs sub and hoping that it will improve my movie bass performance. Can u tell me how is your ssp setting for watching movie. What is your cross over setting for each 5.1 speakers? Did u enable Ebass? Did u connect the sub out to the Svs LFE input? Did u set the Svs cross over to LFE (disable)? I have my front and center set as 60hz, surrounds at 80, cross over at Svs to LFE, and no ebass, but the sound is still not toy expection, thanks for your help.

#1 Tbh Give ed a call, or me as well and we can check everything.. which SVS...as they are monsters..as far SVS config, and did you use an SPL meter to set the SVS up, I ended up using hot gain and adjusting my sub level with the SSP... I have FULL Range Mains, and still keep ebass off and cross as low as possible to them.

#1 MAKE SURE You set the delay settings with a tape measure


(These are off the top of my head but)
Well for my mains, Crossing over at 40hz, Center, Surrounds at 60, 12db per octave not 24db Per octave

Start with no mains, use REW and a microphone and get a sweep of your room... be sure to set the subwoofer delay first..(with a tape measure)...

I would gladly Demo in Naples Fl, no lack of low bass in my room at all.

I will be around today, we can go thru it.

#1 Subwoofer Placement
#2 Rew and Sweeps to tell what the sub is actually doing in room
#3 Amp Gain and SSP LFE Level
#4 subwoofer delay
But everything is set small for me...
Center, surrounds at 60, 12db per octave

Oh and the test tones on the SSP are relative to the volume you have on the processor, you will want to be at 00 for level matching.

Then lets make sure the source is actually outputting 5.1 or 7.1 without downmixing, the processor does say 5.2.1 correct Dolby Digital or Truehd.... Not Pcm and the mode is set to discrete right.

What is the source feeding the system for movies and is it over optical, hdmi, coax, and is it set to bitstream out ?

I also I spoke to Ed from Svs, Give him an email as well if you have any questions on the sub / setup beyond my SSP tips.

Hi thank u for your reply. I brought the Svs sb2000. Finally I got to the right setting and sub placement now. I set my front and center to 60 hz, surrounds at 80hz. LFE connect to Svs. Now the movie sounds a lot better than using the Rel S3 sub. I can’t believe it is almost day and night. The Rel is good with stereo music but no way for home theater. The Svs sb2000 is like $1200 cheaper than the Rel S3, and it is fantastic and with tight bass. I appreciate all your help, if u can give me a quick procedure on how to use the REQ, that would be wonderful. Thanks again.

I am in the same spot with my Ultra 13 have to make corrections, You will need a tripod and a good measurement microphone(About $100) or Radio Shack spl meter and Run an hdmi from your laptop, Get 00 measurements to measure an chirp with the SB, and a response chart, it will go thru a level calibration chart, And your microphone will come with calibration files for Roomeq wizard or a download for them(use them)... the .cal files)

Based on the impluse response sweep you can set the parametric EQ poiints in the SSP, and I would correct highest peaks, not  heavyhanded... In my config I don’t need a sub for music only for movies, you can run ssp configs for music and for movies and assign inputs to configs
