SBS S3X 3 way electronic xover PICS &

SPECS:

I wanted to post some pics of my 1st processor in my SBS electronics division.

Here is some technical info on this xover:

The SBS S3X 3way Active Stereo electronic xover is designed and engineered to be used primarly with SBS multiple amp 3,4,5 or 6 way sound systems. But the SBS S3X can be used in a number applications.

The S3X is designed with a choice of hand made custom built conductive plastic or carbon pots with custom tailered tapers, i was able to design the pots activity to operate exactly how i wanted it to operate. These custom hand made pots can only be offered with the S3X. The conductive Plastic pots are good for over 100,000 rotational turns & the Carbon Pots are good for well over 15,000 rotational turns, for many many years of hard use without sonic fatuige, durability, or tracking issues. .

The circuit board traces where hand layed out with thick traces to asure the smoothest and fastest signal flow posible from component to component, to asure the highest quality would be achieved

The S3X is designed to withstand hard non stop use without failure.


Voicing of the SBS S3X:

I took careful measures to design this x-over to give the SBS S3X a 80s vintage tone.

I used very special technics to age the S3X to give this unit a 80s vintage tone, that will not have any effect on the reliability of my product.


SBS S3X Features:

+ 16 DB of boost in the Sub bass & Tweeter outputs, Fullrange, unity output,

3 front panel level controls can be used for variable gain, to cut, boost, or for custom tailoring & manipulating a recording from song to song with any portion of the sound system on the fly.

Hi quality stereo Unbalanced RCA inputs and outputs, color coded for ease of instalation and hook up

18 DB Butterworth slopes

Sub Bass Freq 20 - 100 HZ

Tweeter Freq 7K - UP

Fullrange 20 hz - 30K

Would you have this additional to your Thrive Isolator?
Is it necessary to have both? or live with one?

when you cut the signal using this unit does it totally pull the signal going to the amps?

Nice one Shorty, actually prefer the looks of this unit to the isolator.
Also a quick question regarding this type of X-Over:
I understand that your x-over will split the signal 3 ways and have outs for sub's, tweeters and a full range output, now I take it from the full range output you would have several other x-over's (Of a different type) for the main house system right?
Can someone post a picture of how one of these systems are wired up? I.e. from the out of the dj mixer into the X-Over etc…

Best of luck with the unit

Yes sir, It's a full cut on each amp.

I think he's talking about circuit design, the techniques he used are similar to those design topologies that were used in the 80's, you know the way a transistor is biased etc... So the unit has a slightly more refined vintage sound rather than being cold and digital like

It depends on what you are trying to achieve in any enviorment. if you do a multiple amplified SBS system for a club of any size or a small lounge setup, or a huge SBS home/pro audio sound system setup like some of my clients have done, both would be incredible and the only way to go, i have clients that have both the Thrive Audio Isolator and SBS Electronics S3X xover, and its outrageous, quite mind bogling & they are extreamily happy with the Product of both processors. But if you are doing 1 amp on a pair of speakers or powered monitors, then The Thrive Audio Isolator in the loop of your mixer is the way to go in that scenario.

Asfar as when you cut any portion of my S3X? it is off, no information will go to the amps or processing. So you can really work a system any way you desire thats why Both units are very important to my systems, because it will let you take the music into a different dimension totally flip it.

Very nice! I'm pleased to see that you are using 18db slopes. I'm guessing thats part of that 80's sound.

Critics of the Butterworth filter say that phase can be an issue around the crossover points. With long folded horn subs though, I'd imagine phase already is an issue, and this possibly corrects it??? I don't fully understand the circuitry enough to understand whats going on. Anybody care to elaborate?

Every filter slope type has its advantages and flaws. With 18db butterworth you get a nice sound, good transient repsonse, sums maximally flat, with little overshoot.

There are filters with better group delay, but they arent as flat. If you read engineering books, they say 3rd order is the highest you can go, and maintain a natural sound, the ear easily notices 4th order and higher slopes.

I like 3rd order filters, you get a nice overlap between ranges, but not overly so. So, the ranges blend together seamlessly, and form one coherent sound. As opposed to 4th oder ( 24db ) where you begin to hear each range separate from each other, disjointed sound I like to call it.

Question 4th order to 3rd order ?

Would it be possible to modify a unit that had 24db slopes and swap them over for 18 db slopes ?

I dont know, you would have to have a tech look at it and tell you.

As i stated many times I'm not an tech guy i just know good sound to my ears & what my ears tell me, But while i was demoing the SBS crossover i was telling Shorty that i love how it makes my speaker stacks sound like one unit as appose to 3 separate componets. If by using the 18 DB Butterworth slopes
it help to give that one big speaker sound the unit does that 100% in my setup.

18db slopes

I also use like 18db slopes. The GSA crossover that i use which is a clone of the original rla x3000 also uses 18db slopes. I like to use 18db slopes on the highs the most. To my ears they give a nice smooth transition.

if you guys ever get a chance to hear one, Pioneer made a series of crossovers back in the 70s

they were silver faced...

the one i got ahold if was a SF-850, they also made a SF-700 and I think another, as well as a D-23 model (which i think was used in the Saint)

anyway, you can adjust crossover points with this unit to preset frequencies and can also change the slope b/t 6, 12, & 18 db slopes....

it was a revelation, to me at least....

with how it makes the tweeters sound thats one thing that stuck out most to me about the SBS crossover. I would love to demo the GSA clone to see what it sounds like on my setup.

Yeah, you know whay? With 3rd order slopes, you get a little upper midrange out of the tweeters, gives the music that CRISP yet sweet sound, trumpets and brass have that certain bite thats just right.

Once you go 4th order, you filter all that out, and even though technically preferrable, it isnt always the case with the ears.

I would love to demo the unit for you. I see your not far from me. I have a few in stock. Your welcome to come by and see for yourself what a great unit it is and also compare it to an original RLA unit. If you like I may be able to stop by you so we could compare it in your system.

I agree that those 18db butterworth slopes are nice...

sometimes i like an even shallower slope too....

but shallower slopes = higher crossover points or less power...

but if you have the headroom in your system, it's all good...

**edit**
i also think that the shallower slopes is knid of getting into the "hi fi" end of the spectrum...
possibly may not be suitable for loud environments...
