Peavey IPR-3000 experience/opinions?

[Balog]

Attenuators are just that: they cut the level of incoming signal. At "max" they simply do not restrict the level of signal coming in. A pre- which does not offer adjustability in terms of the level it sends would probably be the correct application for them.

Fortunately you can get the IPR's virtues in a more conservative-looking (read: no screaming blue light show) version - the IPR's corporate twin, Crest Pro-Lite 2.0 and 3.0, with or without DSP. Essentially the same amp in a different (more professional looking, IMO) package. For PA use, it can also get you around any pesky "No Peavey" riders. Not as plentiful as the PVs at MI retail stores, but available through sound contractors carrying Crest, or places like Full Compass.

Ten minutes with the lid off and some black nail polish, and a dot in the center of each of the front display lights and now my IPR is much less bright, but not dark either.

The Crest Pro Lite includes a dedicated bridge output and switch, so no special speaker cable is needed.

I'd overlooked that added feature, since I don't normally run in bridged mode. And yet it's still priced within a few $$$ of its Peavey cousin. Very cool!

Ok, I tried it running a single channel into a single 8ohm speaker (very heavy duty speaker). I A/B tested it side by side with and QSC 1804 and a Yamaha powered mixer 512sc. The peavey seems to have kind of a midrange or low midrange hump and it's limiting was the harshest (kind of farts on low notes, but sings when plucking) I think the 1804 sounded the best, but the peavey isnt bad, lighter and less expensive. The 512sc is an excelent unit and can act as a all in one bass head and really decent; not quite as loud as the dedicated power amps, but holds its own. I used it as a pre amp for the power amps.
The peavey seems to shine as a dedicated sub amp. I set the internal crossover and cranked "bass down low" Dev. The mid hump gives it great impact, and the bass is good too. It was getting late, so there was no A/B on the sub use, and this is a bass guitar forum anyway.
It seems to be a good amp, and although the 1804 is a lightweight amp, it feels like a brick compared to the ipr3000. The ipr stayed cool in this little test.
in my test, if you turn down the mids a little, the peavey sounds great as a bass guitar amp.

The only time I've seen DDT limiting protection kick in is when there was serious voltage deficit at the wall. You must have been running the unit all out and/or clipping the input.

I had a magnet un-bond and pinched the voice coil, DDT went off like crazy. Kind of helped to pinpoint the lack of volume.

Hmmm - Midrange hump? you must have got a broken one. Do you have any gear you can record with to show the mid-hump?

Kind of contradictory, don't you think?

Yeah, that seems odd to me too. My IPR reproduces what I put into it pretty faithfully. I've been DI'ing my rig for practice recordings and post-eq DI tone matches with my room tone pretty identically.

My IPR-3000 is as audibly-flat as my other amps. Your midrange issue is probably coming from your source or your preamp.

 

[mark in nj]

I'm just saying, it sounded more midrange-y than the qsc 1804, or the powered mixer. Nothing serious, not like Im going to return it or anything. In my opinion it was more like upper bass than midrange, say in the 150hz and up region. if you have been tinkering with audio systems long enough, you can hear differences in powere amps. I can, or at least think I can. Im just telling you what I heard, or think I heard. Ya'll can say Im crazy: but if you say all power amps sound the same, I say you've got no ears. The qsc was run with the same preamp and source. Yes, I cranked it up till it clipped, but come to think of it, it was on a long extension cord, they all were. When I test again, I will use a shorter power cord. Thanks for the tip. It would have been great, if it seemed to have more power than my 15 could handle, but it didnt. I made by bridge cable tonight and will be testing that next, which is how I intend to use it.

I tried the bridging adapter and a shorter ac power cord. It does seem to have some balls now.

Does anyone have a pic of the cable that is used to bridge the IPR amp. Also I have 2 amps to shut down at the same time with the active light blinking. Any suggestions?

Here is my cable, the cable itself is boring old Pro-co 12-2. I made it myself...

The whole deal:

The power amp end; each wire goes to the 1+ terminals on each connector:

Mine:Invalid Link Removed

Red speakon to channel 1, green speakon to Channel 2, blue connector to cabinet.

I use quad core cable and four pole speakons, then 'seal off' the unused leads and clamp them in one of the unused '2' positions so I have more of a mechanical connection for my speakon connectors.

 

[DJ Partytyme]

Thanks alot, even though i dont have the amps any more i want to pass this on to my partner after he gets them back from peavey.

 

[scowboy]

The NL-4 is such a better connector than the NL-2!

I had two of the NL-2's laying around otherwise mine would look much like yours. I leave the cable attached to the amp so no biggie. Nice cable. Like the Canare Star Quad stuff.

I am an electronic engineer ,well now-day many industries using less material for power amplifier construction ,they would spend a little money but the quality is not good like heavy power amp.

You are an electronic engineer? Perhaps you might want to go back to school and (re)learn the benefits of the newer technology (and why it does not need "more material" rather than just saying they need more material without saying WHY?

Specifically study up on the operation of transistors as non-linear switches, high frequency magnetics, and reactive power sourcing/sinking. You might develop a better appreciation for what is happening.
