Peavey IPR Users - How is this amp working out?

I know it is a bit late but I had this on mine. It was a faulty mains lead (cord) that was making enough contact to light the standby lights but not enough to allow it to power up. I changed the mains lead for a new one and no trouble since.

I have been using mine (IPR1600) for nearly a year now and am very happy with it.

When I used your rig in the UK it was that Peavey amp, wasn't it? Man, I bought an IPR3000 and when I'd slap really loud notes on upright, it would shut down...tried it with different basses...real bummer...LOVED the sound:hmm:
 
Hate to say it, but I got one and returned it a couple days later...super light, sounded amazing, but couldn't keep it from going into protect mode and shutting down when I'd slam a hard note into it...bummer because I thought it sounded wonderful.

This is probably a stupid comment considering you're a speaker builder, but that kind of sounds like a volume spike issue. Did you try it with a comp/limiter to cut down on the spikes?

I bet it wouldn't do that if you used a limiter. That's why bass amps often have one. Slapping isn't normal operation for a power amp and if you want it to not shut down, you would either need far more power or a limiter. No amp will operate at a high % of its total output power and reproduce the transient peaks of slapping without distorting, clipping or causing shutdown for one reason or another (there are several things happening at that point). If you consider the fact that a 10dB peak requires the amp to develop ten times its average power output, it's not surprising that it shut down.
 
I'd like to see someone do a fair objective test of the IPR series, including the DSP models. Not some lame "I think it sounds fine" crap, real amplifier testing that includes using an oscilloscope and distortion analyzer and checking input levels vs output.

+1

I would also like to see Peavey take the IPR DSP line, boil it down and give us a mono power amp for bass use. Would be killer IMHO.

I've had similar problems.
In my case the power cord wasn't fitting tightly into the back of amp.
Why don't manufacturers use PowerCon connectors?

Damn it, I ran into this same problem with my still-new Crest Pro-Lite 2.0 (similar to the IPR) last night - except not while slapping. When picking very low notes fairly hard, it went into protect mode. In bridge mode. Unless I used gross amounts of compression, that is. Not OK for my purposes. :crying:

Hmm. I'm having NO issues with my IPR-3000. I use the amp in both stereo mode and bridged mode. My band is quite loud on stage, and I sometimes slap the living hell out of my bass (I'm talkin' volume spikes -- not technique). So far, no breakup, shut-down, protect mode, mechanical buzzing or any other negative affect. I don't think my cabinets are unusually efficient (generally Bergantino AE's, Thunderchild, fEARful). I use effects regularly in my coverband, but I don't use a compressor.

I recently bought F-Deck's HPF-Pre (version 3) that I'm using to tighten up the low end for certain boomy rooms, stages and combinations of equipment. They don't cost much and can really restore a lot of amp power that's wasted amplifying non-musical low-end rumble. This might help some of you who don't feel you're getting all the power you need from your amp.
 
So here is how I have been running my IPR 1600 non-DSP.

TH pedal into an ART PC II, I run that to a small mixer. Depending on the day other things get run to the mixer as well. Keys, vocals, guitar pod, you name it. Everything get balanced at the mixer, then sent to the HPF-3 and on to the IPR bridged to my 1515/66/1. We play at stupid volume levels. I have never had the amp go into protect mode. The HPF really helps with the Keys player more than me, all the low end synth is controlled.

The difference between a bridged 1600 and a mono 3000 at 4 Ohms is ~1,600 watts versus ~900 respectively. Not a huge jump, less than 3 db of head room, but every little bit helps. Adding in the HPF will address some of those transients as well. I think controlling those transients is the key for upright use. At high volumes a little slap can really eat up your head room. I will say its better to go into protect mode, than have something go up in smoke.

I would love to get my hands on a DPS model, as I have a few questions about the use of them in bridge mode. If the DPS was usable in bridge mode, setting the HPF around 35-40 hz would turn that little amp into a monster.

I didn't want to need another piece of gear in my rack to make it work, honestly. I returned the Peavey and got a QSC GX7, which is more stable, but I thought the IPR sounded better. I'll revisit all that stuff at some point. Too busy building cabs at the moment, so I'm just using a ShuttleMax 9.2 and that works great for most of my gigs.
 
I've been thinking of picking up an IPR 3000 lately. I already have an fdeck HPF-PRE on my board, which I think would help avoid any shutdown issues with very hard thumped notes, but maybe the DSP version would be the trick for your issue Mark. That should have a HPF setting built in, which would probably help with that issue and eliminates the necessity for extra gear. I haven't used the amp yet though and I only play electric, so take that with a grain of salt.

The thought has crossed my mind...thanks!
 
So if this amp shuts down during volume blasts, etc., what's it good for? I know bands that run subs through the 1600 with a lot of bass drum pumping though them. I've heard them. This should not be an issue with this amp. IMO, this is not normal.
I think there must be an issue with some of these 1600's then. There is no way you should need to run a HPF to use an IPR1600 with a bass guitar.

Mark was using an upright bass. I use a hpf to protect my speakers more than anything else.
