Hi guys,I have the twins up and singing and so far am impressed. The Twins The 18" story
But I know quite afew of you are or have been Behringer afficiandos so.
Just a question or two?

1. Can I run my .1 outs through the 2496 and eq this way? Btw I only want to use it for my subs.

2. When applying EQ how much amp juice does it use up?

3. Does it act or serve as a pre with a volume control.

4. Can I borrow one if there is a spare floating around (with a monster 2 channel amp )

5. Any thing I should know about them that I may obviously may overlook?

These big boys are to intergrate with the two channel system,next must get a 2 channel pre with HT by-pass.
Sniffing one as we speak :ph34r:

Hi Joz

only for bass duties??  In that case there are cheaper options, the dcx is an 'expensive' unit, and has WAY more processing power than you might need. Not that there is anything wrong with that!

When I add subs to my system, I will need a unit like that, but mine is tri-amped so a little more tricky.

How much eq do you need?  If you can avoid it don't ADD eq, vastly increases amp power required and adds distortion, something that I just investigated recently strangely enough    In any cases there are formulas which tell you how much extra power is required per amount of boost, don't know it exactly offhand.  Have a look at Rod Elliotts site, it will be in there.  Wouldn't JA know straight off the top of his head?

With monsters like yours it's best to increase the gain on your amp and that will allow you to only cut with eq, if you get my drift.

No volume control on these, which is very unfortunate really as it severely limits there usefulness in home stereo. Not sure why you would need it, wouldn't the volume be controlled by the receiver?

Have fun you lucky bugger

The one you need for subwoofer EQ is the feedback destroyer FBQ2496 which is the one I have
You are welcome to borrow it for a spell Joz

It’s great to read that you’re enjoying the new subs.

I take it the subs will be staying in their current location? Have you put the subs in you seating position and done the crawl method to determine where they would be best suited in your room?  :ph34r: (J/K)

Now back to your questions, hmmm I have pondered over your predicament and have considered various options, including throwing out your current gear and installing Bose instead.

Thinking that due to the subs install position you can probably get away without needing individual delays, so the LFE delay in your processor should suffice as an overall. Next you have to get them working together with each other and your other speakers, for this each is going to require a phase control, and some possible EQ. Thinking outside the square, since you are considering purchasing an amp for your subs, have you thought about using a couple of SGR amps which will give you the basic set of controls needed to integrate the subs with your system and room. The money saved on buying say the Behringer gear could go towards the new amps.

[JohnA]

^^^ what he said

i will be getting a couple of those monoblock amps tomorrow actualy to run my B&W speakers as the loaner octagons are going and my elektra map is also gone.

I don't even think you need 2 of them, one will be more then enough

[RodN]

Isn't the SGR amp stuff 4 figures. The behringer stuff is only in the $100 per unit zone. Is this apples and apples?

Joz there are quite a few posts on the eq side of things just remember the behringer eq units ad about 1ft of delay.  Are you going to run them as stereo or as mono? Many questions to come up with a response.

[:)]

I thought your subs were very high efficiency joz. you could probably even drive em off the spare channels of your elektra to pretty high spls joz. norpus was running his 18" big bertha's off the elektra at one stage without it even breaking a sweat.

With no published price lists, and plenty of prices getting bandied around then yes I believe the SGR amps are around that figure. And yes we’re not comparing apples with apples; however the subs are going to require amplification long term (as per some of Joz’s posts regarding the new subs), currently using spare channels from Electra to drive them.

My suggestion was based on firstly not knowing what suitable amps are available in Australia, and secondly the SGR amps have several smarts already included, including a crossover for possible 2ch integration.

Yes the SGR plate amps are top notch. What they have done to Norpus' system is just outstanding.  Joz do your subs have a plate amp location in the back of them or were they designed passive?

BTW Joz I'm sure you'll take Ken up on his offer as he's closer to you but my Behringer xover and Feedback Destroyer are also idle at the moment so you can borrow them if you need.

[terry j]

isn't this whole discussion about bass integration (which to me also encompasses any needed eq) rather than amplification?

How is getting an sgr amp going to eq his bass?

[JohnA]

because sgr can build in if if needed

now Joz is thinking of getting that behringer which is $499
he is also propably wanting an amp maybe another behringer amp for around $400

for the same price he can have a single SGR plate amp with the electronics.

The prices quoted on the plate amps were in the boxes, on their own depending on which power model you needed wouldn't cost you anymore than around $1k

As for the behringer, sure give it a try Joz if you can get a loaner, in my setup in introduced a nasty hum, doesn't do it in all systems though so something you need to try.

hehe couldnt help but notice that one ! hehe, sniffing it ? hehe it wouldnt be a black thing with gold writing on it now would it ? hehe

ps joz, back on topic, when I was demoing subs the guy at livingstone audio used a little paradigm xover unit, had a vol level and xover adjustment on it. Beaut part was for 2ch it took speaker level in and out of the amp and allowed you to set level and xover with it. seemd pretty simple to use and of high quality and did a great job to integrate with the mains for 2ch if thats what yoru trying to do. you'd have to ask alex ? I think it is over at livingstone about it. theyre pretty inexpensive I think, its what paradigm sell to use with their subs.

anyways jsut another option...

edit duratone appear to have them for sale here under "SUBWOOFERS CONTROL UNITS" and appears theres three different types.

Correct!

Until Joz has done some in room measurements then discussion of what type of add on equipment required is rather meaningless IMO.

Joz has already indicated that he is going to need some form of dedicated amplification long term. (What other amps would be suitable?)

Joz may also want to integrate his subs for 2ch further down the track. (How will he do this?)

Remember there are multiple subs, so EQ is the last requirement IMO.

A great find Al.

It gets good reviews also…if Joz were to go this way then the X-30 would be the one to get with its three crossover settings, plus he’ll need two them.

hi spearmint, didnt realise on the reviews, anyways thought something pretty intersting at the time. I might be wrong, but If I remember it was a stereo device too so two would not be required, one unit woudl do both subs, but anyways somethign to look into for anyone considering.

Nice units- good find
I do think the SGR units do that anyway - and for the price of two of them, you could get one sgr amp that would also drive your high efficiency subs Joz plus give you the control. And if you wanted the FBQ2496 to EQ it up (after correct placement and running sweeps) then that is $270

[the joz]

Thanks for all the info guys once again.I'm going to have to digest all of this and speak to as many of you guys as possible before I go ahead with anything.

Ahh the dilemmas Though the SGR route sounds tempting.
Also I will take up some of thge kind offers first(Norps) At least I should be able to make an informed decision then.

[JohnA]

i currently have 2 of the SGR monoblocks here with al the x-overs and volume controls bypassed. So basicaly full range monoblocks
1 of them is Norpus's...thanks Norpus, i'll run her in for you

All i can say is so far i am very impressed with them.
They are driving the B&W's with no problems at all, plenty of headroom, and ultra dead quiet.

hehe john, if theyre driving the B&Ws and theyre dead quiet, you'd hope the amps had plenty of headroom...if you know what I mean hehehe

[JohnA]

lol, very funny Al

as in dead quiet i meant when no music is playing
unlike someother amps i have had which either have loud hissing or a very slight buzzing noise

Can't compare to the elektra reference as i don't have it hear so no point making any judgments there.

hehe know what you mean, just having a bit of fun ! hehe good to hear you still got some amps to pump through the music

Any casework photo's for us John...?  You know how we love pic's...

[JohnA]

no caseworks as yet Rod
just in the painted boxes for now

don't worry once the casework is done you can be sure i will be sharing the love around
