Just wondering if anyone uses the QSC RMX series amps - more specifically a rmx1850HD - this is a new "Heavy Duty" addition to the range capable of more power for long periods into bridged 4 ohm loads - I want it to drive a pair of subs - will it happily kick ass all night?

Also whats the difference (apart from weight) of the PLX series - would i be better off buying a 1600 watt plx or this 1800RMX for the bins - bearing in mind the bass is never gonna be thrashed - probly run it at about 1.2K most of the time

Any help appreciated
Many thanks
Steve

I use QSC RMX's for the Hire Rig. Although the biggest I use is the RMX2450.

Email me if you make a decision and want a quote

A club I work in uses 4 of them to power 4 bass bins, they've not let us down so far and thats after 2 years of no servicing and thrashed Thursday - Sunday. A good buy i reckon although i believe the Numark dimension amps are also made by QSC which are slightly cheaper??

are the ones in the club running at 2 ohms (or 4 ohms bridged?)
Wouldnt dream of buying a numark amp - even if it was almost as good - its like crest and pevay - i would always buy a crest even though its now owned by pevay!

4 Ohms bridged I believe. I'm currently using a Crown Macrotech for my bass which, from what ive been advised by one of Scotlands leading sound installation companies, is as good as you can get. Top end is a C-Audio RA 3001.

See what you mean about Peavey tho!!!!!

There's nothing wrong with Peavy amps. Solid, reliable and come with 5 year warranties. Many are still in use after 20 years of operation. Be objective not brand biased!

Im not being biased - in my opinion the pevays dont look as pretty, arnt as well built and dont sound as nice as the crest's. They have a higher noise floor level and a much lower damping factor into low impedance loads.
Its good to hear that your pevays are still good after 20yrs on hte road! thats a plus point for themn which i wouldnt have expected - but crests are renound for lasting for decades on the touring circuit - they arnt regarded as the best amps in the world (along with crown / lab gruppen etc) for nothing.
Now saying that - to be honest - when is a mobile dj gonna need all the extras - for mobile disco use your probably right peter p - whats the point in spending the extra money - they are probably gonna sound the same anyway - guess its just personal preference but is certainly based on objectivity.
its like on topgear last night they had a lotus elise and one of the new vauxhall roadsters - what would you buy for the same price - a lotus or a vauxhall.
Yeah - i know u would - even thought the vauxhall actually gives better performance

Hmmm, yes but is it for your Mantle Piece, or a functional piece of equipment??.

My own considerations are build quality, distortion levels (% THD), Reliability and weight before worrying about how many flashing LED's it has or the fact that it has a lovely blue led power indicator (which seems to be a selling point these days, lol)

An amp is essentially a workhorse, rather than a lighting effect and is designed as such. Most D.J's don't have the time to watch leaping leds at a gig . For this reason a limiter is also a good friend of the D.J, just in case he / she gets carried away with the levels. The Peavey sonic limiting system (Compression) is one of the best built in limiters around.

Now that is an unbiased opinion - I don't distribute Peavey!.

On the other matter:- I own a Vauxhall, and I would never have another one again - since this one is on its thrid engine management system!.

i have grown up around peavey, my father owned a sound hire company and started buying peavey 15 years ago, obviously we dont have that same gear anymore, but the some of the people who bought used stuff off us ten years ago are still using it.

I know when i went to buy my rig the first thing i priced up was peavey.

P.S> have you guys seen the special DJ model Sp4's by peavey???? Sp4's go very hard and sound terrific, but only if you have a VERY POWERFUL AMP, you cant be cheap and underpower the cones as the black widdow cones will destruct.

worth a look and a listen in my mind anyway

Chris
Just out of interest using your considerations in particular in relation to weight what are the best lite weight amps you would sugget to drive a pair of art 300's and a similar lite weight amp for some AS800 subs on a bi amp set up

I'd recommend the QSC Powerlight PL1.6HVX which is a 4 Channel Amplifier directly manufactured for Bi-amping. Delivering 300W into 8 Ohms for the ART-300's and 725 Watts inot 8 Ohms for the Subs (I'm not familiar with the Model - I assume from the model number they handle 800 Watts?). However the price is around £1500

Dynamite Disco:
I agree with you about the functionality aspect of amps. But a point that's been overlooked is that when comparing brands we need to compare apples to apples. All brands have entry level and top line products. Please compare the specs of Crest CPX2600 to the equivelant peavey PV2600, and tell me which has higher noise or lower damping. And as Chris pointed out, Peaveys DDT compression is among the best there is.

No dought, Crest is a world class amp manufacturer (Which Peavey owns) but at least if you compare specs,
compare peavey's top line with the Crests amps in the same price range

Yeah mate - dont get me wrong - pevay make some great amps for great prices - it turns out i may get one to drive mid highs - wasnt meaning to slate em - but if i had hte extra money i would go for a crest over a pevay - its silly really - but we do it every day with clothes etc.


I just wish i had had more cash when crest went through their liqidation - the amps were flying out of there for ridiculous prices i remmeber!!!!

Yea me too. Have you seen the new line of Lightweight (Switching) Crest amps, they seem to be causing quite a stir in the pro industry. They're marketed in direct competition to the QSC PLs. BTW did you know that the RMX 2450 costs only £400 in the US as opposed to the extortionate £719 here in the UK. That's why they are so popular in the US. The Equivalent PV2600 cost £500 in the US and the UK. So naturally some folks in the UK assume that RMX is better quality because it costs more...not the case. Its more a distribution issue with QSC that hikes up the price, not necessarily a quality issue. Peavey has it own production and distribution in the UK, which brings costs down. If you can, do an A/B between the two amps, love to hear your findings. Thanx

I can getthe rmx2450 foor £610 over here but yeah - the price diff is ridiculous especiallly with makes like crest and QSC. The LT/ST amps you are talking about are amazing - ive heard em - and they dont weigh anything!. might save up for one of those instead of going for the qsc rmx, or perhaps ill get a plx - i just need to sit down after me exams and do some indepth investigation as to which amp overall is gonna work best for me and my subs.
I wanna sort out my lighting rig first tho - more dmx stuff is needed.
Have you seen the prices mobile djs charge over the lake as wel - they go out for hundreds! - and pay less for gear - what do they do with all the extra money! lol

And don't forget that there are "SOME" dealers around who can beat that

I know a lot of mobiles swear by Peavey, but I bought two PV range amps and returned them, simply because I wasn't impressed with the sound quality.

Amps can often have exactly the same technical Data (which manufactures often interperate/measure in a "house style") but differ greatly in presentation. The bottom line here for me is sound quality (along with oomph and headroom) and of the opinion this an area where the RMX is miles ahead of the PV range.

Dont know any competitive dealers round here! do u?
Yeah chris - ill def give u a call before i buy anything to see your best price - coz it looks like its gonna be better than the best of the rest!
thanks for everyones input on this topic

Dynamite:- Please read THIS POST HERE I think it is important that you familiarise yourself with the rules before you continue posting

There are many forums around where you can go and ask this type of question, but not on here.

Take it easy chris - that was clearly a joke. As in - you are obviously a competitive dealer - dont see anything in the rules about the use of sarcasm.

I assumed that when you posted

You were referring to yourself - a bit of an amusing comment about your prices so i thought a bit of humour would be ok in reply.

Sorry if i offended u - wasnt my intention

Also Stating this:

immediatley afterwards just emphasises the fact that the comment was not serious and that indeed your prices are very competitave.

Sorry if i have misunderstood the reason this post was unacceptable.
Sincerest apologies
Steve

I didn't see the joke in there either all I saw was an invitation for trouble can u imagine what would have happened if anybody new to the forum had replied to your question and published some names for you?. You havent been here long enough to have witnessed the trouble that chris had on here some months back which closed the forum for a while, so dont blame cris if he is quick to nip these issues in the bud. Chris and the mods are here for a reason and posts like yours cause them even more problems.

chris is in business and this forum is the result of that business, when you screw about with somebodies livelihood then it ceases to be a joke. knowing how quick that chris deals with these issues you r lucky ur still a member

Lets not take this over the top mate. Ive made a mistake, ive apologised for it so why dont we just move on. I dont know what people have done on the forum in the past but i can assure u im not here to cause any trouble etc. again - im sorry chris for the inappropriate remarks
Forgiven?

Let's not generalise about a status of a company's product based on isolated and subjective evaluations.

I own 3 PV2600 amps and they sound absolutely fantastic, build like tanks.

There could be many reasons why an amp doesn't sound as it should, among them setup errors. Amps could have been faulty (as can happen with any electrical item).

But one things for sure: you would not be able to tell the difference between the RMX & PV running at their optimum with the same signal input. I A/B the Crest CPX2600/Mackie2600/PV2600 & RMX2450,
and found virtually no difference in sound quality. Neither did other independant audiophiles.

Your comments about Tech data: True, cowboy manufacters do manipulate figures but reputable companies adhere to agreed international standards e.g EIA & FTC. Peavey rates all its products in accordance with these rules so that the consumer can fairly make comparisions and choices.

Time to close this I think.........
