Crown XTi power amps?

    Hey Y'all,

    While I've salivated over the PLX2s, I've seen these (the XTis) on the Crown site. They are lightweight and use some digital control. A search turned up nothing - so I thought I'd check with the TB collective conciousness to tell me why these would or wouldn't be good as a lightweight amp in a bass rig.

    Crown XTi specs

    XTi-1000 275/500/700W stereo 17lbs $499
    XTi-2000 475/800/1000W stereo 17lbs $699
    XTi-4000 650/1200/1600W stereo 17lbs $999

    reasonable shallow at 12.25". Drawbacks I've seen on a quick scan - XLR inputs only, uses digital control of bridging, etc. But on the plus side it has a built-in crossover (if you are biamping or using it for PA as well).

    So what do the amp experts thing about these?

    Price/power ratio seems about inline with the PLX2 '04s (at least with an 1804 and a XTi-2000) but these are 2Ohm stereo, 4Ohm bridged amps.

    Dunno how I've managed to miss this series. The built-in DSP looks extremely cool. Especially the EQ section.

    The Crown looks mighty interesting. :eek: I'm looking for a new power amp. The XTi might be it. Sure would like to hear a review. :bassist:

    These must have just become available. When were they first shipped?

    I just noticed these in the latest AMS catalog. They look pretty interesting. If I decide to go with a pre/power setup, I may just have to give one a try, unless there are some drawbacks to them that someone happens to know about.

    The specs read very nicely. Prices seem to be in line. And, well, sorry, but to me at least, they look great cosmetically. I could live with XLR inputs.

    Are there ever any Crown managers/employees who post here? Maybe they could give some XTi info.

    The Crown XTI is a new series to replace the CE amplifier which is going to be discontinued in 2006.

    I think these only started shipping in January. Anybody got one? Anybody ordered & waiting to receive it? I've found a place that will do the 4000XTi (3200 bridged @ 4 ohms) for $870. Got an itchy trigger finger for that price.

    Sorry, gone for a while. Check out www.rmcaudio.com . That's the price they quoted me.
  11. Ooh a light weight replacement for my Micro 1200?:hyper:

    These do look pretty cool. I wonder, can teh delay time get short enough to do time alignment of the horn & woof drivers of a 2 way cab ... I have no idea the scale of that interval but it must be very, very small.

    Wow - these look great.
    They seem to be Crowns "Class-D" (PWM) entry.
    Lightweight, efficient (low heat ), great performance - and great price!

    Yeah, that's the intended purpose of the delay. You also get user presets for different cabs, and it's all editable by USB from a computer, or from a menu interface in the amp itself.

    Mal, you should buy one of these so I won't have to.:cool:

    Crown has had several PWM amps (K series, iTech) in their line for quite a while. None of those are nearly this light or cheap though.

    Someone please buy one & tell us about it! If not, I think I'm gonna have to do it myself, lol. :eek:

    Is there anything like this in a preamp, i.e., DSP with USB interface for feeding a traditional power amp? I only ask because the concept looks really neat, but I don't need that much juice.

    You can pick up one from CAD

    Hello To All,I finally decided to post up!I'm always here checking out what you guys have to say.I've made some purchases base on the opinions here on this forum.For the most part your wisdom/opinions have guided me in the right direction.I'm back to playing BASS and have acquired some nice equipment,thanks to you guys.Anyway...I recently purchased a XTI 1000. I run it in mono mode to drive my El whappo cabinet.I'm running it from the line out of my EBS TD650 head(the 650 drives a Epifani 4ohm 210 cabinet).The XTI seems to be a state of the art amp in regards to technology.The amp has parameters to setup sub and sub synth settings.The amps xover is set up for channel 1 to do a sub and ch 2 to do an high output driver.It has user presets for building and saving your own setups:hyper: .The amp is lightweight,sounds good,drives without showing signs of clipping.The one thing I have noticed is that the amps fan kicks on when driving the cabinet.Seems to me to be a top contender.I was looking at the QSC PLX 1602,but for the price I paid for the XTI, I couldn't buy a used 1602.I perfer Crowns sound for lowend anyway.Nice product Crown!
  20. I believe these are based on the I-T Series...I have 4 I-T6000's running a 2 Pair of JBL SRX725s and 2 pair of JBLSRX728s...These things R O C K !!!! Onboard DSP out the yazoo including auto time alignment and phase correction and all crossover and limiting parameters for the JBLs and a BUNCH of others already in the internal DSP. Does self diagnostics and continuous load monitoring WHILE passing audio...very cool stuff. They sound great and have a damping factor greater than 5,000 from 20hz to 100Hz! Talk about a seriously tight bottom! This is one of the better sounding amps for PA use I have ever heard. I have not put one on my Bergantino to test...to tell you the truth, I like the 750/NV610 match so much I never really thought about it...:D I have NOT had the opportunity to check out the XTis but if they are even remotely close in terms of capability they are probably off the chain! I am heading to Richmond on Monday and if I can find one I will check out the XTis and report back...by the way, before you start thinking about the I-T series they are really expensive, from around $4K list for the 4000 to almost $8K list for the 8000. I picked up my 6000's as B stock (Crown Demo units essentially brand new) from a friend of mine for a tad under $2400 apiece...he doesn't have any more (or I would probably ahve gone and got those 2!!) If you get a chance I would check out the XTi and take em for a test drive.

    Here are some specs from Crown on the I-T series and the XTi may have some similar features:

    The Crown I-Tech Series offers amazing power, light weight and ease of use for touring sound and installed sound applications. Onboard DSP provides a wide array of signal processing, greatly reducing the need for rack components and rack wiring. Onboard DSP features 24-bit, 96 kHz A/D and D/A converters. All models are compatible with the HiQnet Network and TCP/IQ networking. Digital audio and HiQnet/IQ control signals connect to the amp via a single CobraNet cable in optional CN models, coming soon. Pushbutton DSP presets simplify the setup for various loudspeaker arrays. The Global Power Supply works anywhere in the world, and offers PFC (Power Factor Correction). It is a switching power supply for reduced weight. I-Tech amplifiers have the highest output voltage in the industry (200V peak), which provides clean transient peaks. The 3rd-generation patented Class-I (BCA®) circuitry couples power efficiently to the load and allows low AC current drain. A front-panel control screen shows advanced diagnostics and status information.

    * Unmatched power in a 2U lightweight chassis.
    * Global power supply with Power Factor Correction.
