ALWAYS have one PSU disconnected from the other PSUs and incoming line voltage.  Why?  Because what took the first PSU down didn't auto-magically fix itself.  When you hook the the second PSU and it fails, you at least have a working PSU for when you discover the shorted umbilical power cable or the massive short inside the console.

While it's possible that a PSU will spontaneously fail for no *external* reason (Soundcraft, 30 years ago), it's unlikely.  Your 20 year old Midas PSUs should be recapped, and possibly the bridge rectifier replaced as well.

Been there, done that, gave away the t shirt.

I think this is good advice.  You'd be moving from a 13 year old design (the LS9) to a 7 year old design (X32/M32).   

There's nothing wrong with the LS9 for running IEMs - it has 16 XLR outs which would let you run up to maybe 14 mono mixes (assuming you're using two outputs for your main system).  This would be done with the sound person doing the mixes for the musicians.  This approach is both better and worse than the various personal monitor systems out there (personal monitor systems add cabling and stage clutter, not to mention cost.  It's not that hard to mix monitors from the sound board).

If you do decide to look for something else, check out the Allen&Heath SQ series.  You can use a phone app for user-adjusted mixes without the cost or clutter of a personal mix system.  If you do want that though, Allen&Heath has their ME series personal mixers.
Agreed.  If you need more than 32ch and/or just want a newer, better mixer - check out the SQ7 and ME-1's.

To keep things clean on a crowded stage I bottom mic using an Onstage msa-9508 clamped onto the hat stand with an AT pro37.  High pass at something like 250Hz and never had any rumble issues.  This is for rock bands.  If it was jazz or lighter smashing of brass I would mic the top.

If I could HPF at 2k I would.  Too much snare bleed in the HH mic most of the time.

Back in my analog recording studio days we almost never put a separate mic on the HH, we'd aim the snare mic to get the desired balance.  That was 30+ years ago and needs/desires change, but instead of fighting something, make it work for you.

Has anyone had problems using freespeak in Nationwide Arena in Columbus OH?

I can report that FSII 1.9 works very well here.  With a single antenna 50' out into the arena I listened on one pack and talked on a second pack and verified coverage for whole arena.  some places the voice gets a little gravelly due to too many packets being replaced but over all it is 95% and always intelligible.  I am using BP V1.07 and antenna V.40.

currently have 2 jbl prx815w tops over 4 rcf 8003 mk2 subs, and it was quite the system

how ever a tweeter has blown and i need replacments quick, cant wait for warranty repair.

my first choice would be jbl srx15p but these are not available.

what is ready to collect at shop:

yamaha dsr 115 136db 1400w 900
ART 745-A MK4  133db 1300w 1100 (guy in shop swears this is the best option)
QSC equivalent

as these will always run in high pass the descision is not so easily made, it is the specs on the compression drivers that has got me thinking. rcf is 1.4" with a 4" voice coil vs the yamaha 2" voice coil 1" throat.

on the bear face of the figures and description i just do not understand which would be the best choice.

the music is strictly house music, ive got the bass sorted and just need ear shattering highs that i can dial back to suit and leave some headroom.

buying in next couple of days, desperate for help

ps, should i insist on the srx15p no matter what?!

Or try this: work with your service center, buy a new diaphragm and have them keep the old one for JBL warranty, and when the new parts are approved, you have a spare.

It seems very silly - in the Monty Python manner - to purchase a pair of new loudspeakers because you have an HF failure.  Hire another JBL or a pair of something else to get you through the gig.

Stihl has one of the best names in the chain saw industry, and my oldest daughters boy friend, who owns a tree service, must have 30 of them. That's why I bought a Husqvarna,...


I guess you're a better lumberjack than your daughter's boyfriend?   8)

btw, If anyone is looking for a used chain saw, PM me.  My dad has them stacked to the rafters and we need to move them before he stops [moving].  Sorry for the commercial but this thread seemed to be one of the most appropriate. 

Lastly, Bob, I sent a PM a little while back.  Just wondering if you got it.

Haven't used them, but I am a little sceptical about their claims - there's only so much a reflex-loaded 12" cone can do in the bass department.

Chris,
120/126 dB for a 4" voice coil 12" with 3000 watts seems a reasonable claim.

The use of an isophasic wave guide instead of a conventional horn certainly will impart a "distinctive" dispersion pattern ;^).

Looks like the 1.5 update has been pulled? I downloaded it yesterday but its not listed on the site now

It looks like you are correct - I am going to keep waiting even though I downloaded that file, since I'm assuming that they need to fix something.  Also, yesterday I checked my beltpacks and they are currently on 1.06, so I'm assuming they will come out with a new version for that.

To answer your question, as the owner of a pair of 745s that's what I'd choose. Fantastic compression driver in that box and I love the 650 Hz crossover point. With a beefy woofer, they also handle bass well which is nice if used without subs.

That said, it does seem silly to buy if you have any other option - renting, hiring, borrowing. Unless you know it isn't the case, there's a decent chance you just need a diaphragm replacement, which is likely something you can do yourself.

To test either make extension leads from the box that has the problem and run to the compression driver in the one that's working OR swap power modules and see if the compression driver is working. If you find out the compression driver is bad get it fixed or replace yourself. Even if you have to pay for it yourself it will be 5% the cost of buying a pair of new speakers. Even if if a new diaphragm doesn't fix the problem, it's not a bad idea to have a spare in case one does blow.
