Pro audio power amps

i never see much peavey in my area. it's usually crown and qsc all the time. i never had chance either with gx models that replaced the older class h models. they also support dsp like the xls models but the gx series dsp options are close to xti models i think with selectable filters and slopes and time delay and so forth. i was gonna pick one up but it only being dual/stereo and can't be bridged and only rated down to 4ohm load i decided to pass. so i went and bought an xti 4002 since i always had good results with them and they never failed on me. the xls models are very light too and i would look into those as well and sound good in my opinion. xti series is class a/b till you get to the 6002 and they're bit heavier(about 18-20lbs) but, in my opinion sound amazing and have very good dsp control. they're pretty effiecent and works well off a simple 20a circuit. only gripe i have with them is i wish their paint was more scratch resilient cause i like to keep my stuff perfect and always careful mounting but, ended a scratch on top from simple stacking which irritated me a bit. my xls i dropped several times on concrete,banged it it up,threw stuff on top of it and not a single scratch.

yamaha pro stuff is very scare around here too and to be honest not much approved of when it comes to pro applications. lot of yamahas were known to blow and not be reliable under grueling conditions. i used yamaha before for home use and liked their m series separates but, even home i had issues with them blowing on me being pushed and one even caught on fire on me lol. they're design though and sound is good though. just not pro material in my opinion. i was gonna invest into macrotechs in the past but, having a 30a and 40a circuits available is very rare so i'll be straining them and blowing circuits very easily. i blew 20a circuit with just my xti 4002 before but, i was really pushing beyond it's limits under stressful 2ohm load. circuit gave out before the amp ever came close to giving out but, under careful supervision and monitoring they'll work fine and great with 20a circuits and 20a circuits is pretty much very common even, in houses. i always check circuits of a place before i proceed. that's another reason why class h and class d is becoming more preferable for on the road people cause not everyone has proper circuits to run off.

 

Yorkville rules the roost in my town (it's practically a monopoly), and these days are pretty much the only power amp aside from Behringer that you can buy new. I generally like Yorkie stuff though; I find their amps solid and consistent. I've gone through a bunch of their cabs and like their powered speakers more than QSC's equivalents. Yorkville isn't well known in the US though.

I have a Yamaha P7000s, though admittedly I've never pushed it hard, even running on subs. As far as I can tell the fan has never kicked on for me. I like the design of it, but it sounds a bit dull to me.

p.s. anyone else seeing a bunch of links with green arrows showing up in Rex's posts?

 

Yeah, I see the links with green arrows in Rex's posts as well. Kinda weird as he's the only one doing it on this site.

 

I see it too!

 

i don't know why it does that. it seems only do it on this site. i been having issues with opera on this site for some reason. never did it when i used my phone on this site before as far as i remember. i just got comcast and so forth so it's been long time since i ever used my laptop online so, don't know. gonna try chrome later.

 

Interesting... I use Opera and there's nothing weird on my end.

 

i never see yamaha pro stuff much around here. i was thinking of the p7000s when i was shopping few months ago on an amp but, decided to stick with crown again. i saw a p5000 too on cl and was tempted to buy it but, guy wanted bit too much especially for how road rash it was.

i do plan on buying another xti series for mains cause they sound awesome but, been itching to try out thr hyped up k2 amp maybe and see if its worth anything as people say it is. only gripe i heard of them is that sleep mode function so amp run cool and modding/removing the resistor to eliminate sleep mode will cause amp run hot on idle cause it'll be dumping 250w into the outputs...i mean always been interested in crown bca designs but, i dont know bout risking it picking one up and if output goes out it's 700 bucks to replace them...i just been tempted cause my local sam ash has 3 k2's that been sitting their for months on end with no interest. i also been curious of them cause the newer mark levison no.53 mono blocks are based off k series that you always see hooked up to jbl m2's and thoes odd looking wilson alexandria xlf...

i also know yorkville stuff. see them once and awhile. i like of their stuff.

 

probably my computer then..or opera needs an update. im on my phone now and don't have issues at all on here.

 

I've been wanting to try a Crown K1/K2 for a while but I never see them locally. I came really close to picking one up from a guy a couple provinces away and we even figured out all the shipping hubbub, but then he plugged it in to listen one last time and decided it was too nice to let go. Bah.

I've been looking around at some lightweight amps. Right now in my local classifieds there's a Peavey IPR1600 for $225 and a Crown XLS2500 for $550 (prices Canadian).

 

are they new prices or used? the crown looks pricey there still. i paid 650 bucks for mine brand new a year ago and avg used prices on my part is about 350 just for the amp itself still. never used peavey class d stuff. just comes how much power you want and so forth. only bonus with crown is their warrenty.

i never had issues with my xls 2500 the year i owned. i use to use it on subs and never had issues pushing it on stressful loads. it has been good to me.

 

Both are used, though the Crown is "like new" and supposedly still has warranty.

 

hmm. i don't know then. i mean the crown probably be better bet for reliability,power and sound and has pretty good linkwitz-riley 4th order crossover filters built-in. i like how it allows low-pass down to 50hz atleast which is useful for more flexibility on systems when comes to subs then just having a fixed 100hz crossover like some of the other amps from other competitors. i think 550 though is bit high and would see if can drop the price a bit if possible and give it a test to see if you like it.

 

Do you have any experience with the old Yamaha P2200/PC1002 amps? I just kinda like the look of them.

 

the p2200 is i think same as a m2 but, basically in different chassis,has a fan, and has protection circuits. lot of people love the p series cause fact they're similar to the early Mx series before the newer Mxx series came out.

the pc1002 i have no idea. looks newer model and from reading there is like couple versions with meters and not and one without protection circuits...

 

I think the PC1002 is the 2200 but with an updated protection circuit. The guy is asking $700 for a pair of them, recently fully serviced and recapped. Not too bad.

Hmm a Sumo Polaris just popped up on the local classifieds. I've never seen a Sumo in this neck of the woods.

 

the p2200 is like 300wpc and pc1002 is like 70wpc@8ohms if i remember. the p2200 is defiantly different and earlier power amp. if asking 700 a pair for both models fully serviced ill get them. like lot of yamaha older stuff. i just had bad results with the new late 80's m45,65,and m85 models that would fry outputs... the p2200 like the m2 i beleive uses high current v-fet outputs, defiantly lot more resilent under heavier reactive loads.

 

Hmm, the guy is selling PC1002's, not the p2200.

 

well, i dont know. i mean they're still pretty good amps but, probably wouldn't use them for heavey duty use except horn use in biamp situation. the p2200 on under hand very good amp and wouldn't mind running them in brided/mono full light sub duty and fullrange stereo/dual use and defiantly great for home hi-fi use.

 

Have you ever seen a PA speaker actually catch on fire? One of the venues I set up managed to blow a speaker; I wasn't there, but they said the back of the cab caught fire. I haven't taken it all apart yet, but peeking inside it looks like one of the caps definitely went kaboom.

I'm trying to think what could have caused this. They said it was only being used for a vocal, so it wasn't being driven hard. But could it have been residual damage from someone earlier pushing it too hard? A couple weeks back someone incorrectly wired things up and had one speaker across the black binding posts and the other speaker across both reds (no, it wasn't in bridge config), so I'm wondering if damage could have been incurred then.

Ugh, or for all I know maybe it's just terrible power in the building. Or just gross ineptitude by the people in the building (probably this one). In half a year they've managed to blow a Mackie mixer and two powered speakers, damage a 16 channel snake, damage a QSC amp, set fire to a passive speaker...

 

I saw an amp catch on fire before but, never a speaker. I seen voice coils melt and lock up at worst but, never catch on fire. Sounds like really bad user error by way you put it. It probably kept getting direct DC from the amp or even signal clipping from preamp/mixer if overdriven will send straight DC through the power amp and to the speakers. Must been one hell of a DC surge to catch the speaker on fire.

I heard of bad faulty ac power of some.buildings and people complain but, never experienced it. I mean its possible. A guy I knew complained a lot blowing loaded jbl 2226 woofers and loaded 2242 sub's all at once all the time and those drivers are known to be hard to kill. Thought it was the macrotech 2400 fault but, it was due to a surge in the ac of the building. Amp never failed though but couldn't say the same bout the speakers.

Also, maybe can be the speakers too on its internal passive components exceeding thermal capacity and melting and materials used are most likely flammable and just something sparked..I wasn't physically there so I can't say for certain.
