  1. Crown K2 Problems

    If swapping modules, first off, special care has to be taken doing so. The numbers to look for are the part number of the Main board, and the part numbers of the Output modules. If swapping around different revisions of these modules, although I don't believe any permanent damage will happen, you will not be at all pleased with the resulting performance. I don't think the revision rules are posted anywhere. Your absolute best bet is to send both to Elkhart for service. They have a couple fellas that are pretty good with this model and they should be able to fix you up. The more use use them, the more you risk unrepairable damage.
  2. K2 AMP

    You could have something very simple, you could have something not so simple. Very good chance it can be fixed as good as new. Send it to Service in Elkhart where they will fix you up. Don't mess with it because you can accidentally cause alot of damage! http://www.crownaudio.com/forums/style_ima...icons/icon5.gif
  3. Thank you for ur reply, I checked it out and unfortunately the XLS 802 is different and does not have that rectangular cover thing below where the 602 does, instead there is a circuit breaker button below the IEC on the 802. I'm quite sure you would be correct tho if it were XLS 602. I think my chances are starting to run slim, I can't find any info on it. I'm thinking maybe the circuit breaker replaces the selector on the 802 and perhaps there is no selector. Hmm, I hope I didn't just blow my money away. I'll keep searching for info, otherwise I'll have to start thinking what else I can do. but thank you again. The only way to change the voltage will be to replace the power transformer. Last I knew the Crown parts department was stocking some of the higher input voltage ones. If you get a new transformer just put in the new one exactly like the old one. Hold on to the old one because there is a real good chance that there are next to none of those left in the world. http://www.crownaudio.com/forums/style_ima...icons/icon1.gif

  5. Buzzing "relay" in PS-200 at turn-on

    There is a good chance that C4 on the little board with the relay you speak of is bad. There was an update for that cap many moons ago, and your amp may not have gotten it. Or, due to age and use (I think more due to age) it doesn't work as it should. Replace it with an electrolytic cap, 10uf at 100V. I think the original designed cap was less than 100V and that was why the update happened. The Crown part number for the replacement cap is C 8889-5, if they still have it. If you have to search for an alternate part, do not go lower on the voltage rating! No problem to go higher. Also, PAY ATTENTION to the polarity of the old cap BEFORE you take it out. Put the new one in backwards, be prepared to buy another one, clean up a mess in your unit, and a loud BANG! Hope this helps.
  6. crown xls 802

    It could be the power supply. If you still have warranty on it, send it in to Crown for service. Nothing more you can do.
  7. XLS-602 Intermittent Fault

    No, reversing the speaker leads will only affect the sound. This is assuming you only have it connected to speakers and no other equipment. Send it in for service describing the problem. If it is a "B" series, it is a real simple fix (for a tech).
  8. Little or no bass

    Check the phasing of the speakers. If they are wired out of phase from each other you will have less lows because one speaker cancels the other.
  9. XLS 802 Help

    Sounds like you either had an output transistor(s) fail, or the bridge rectifier in the power supply might have failed. Your best bet would be to send it in for Factory Service. Being an 802 it should still easily be covered under warranty.
  10. Definetly not standard. As suggested, open it up and see what is wired to it.
  11. XLS 402, no lights, no power

    Check to see if any output transistors are shorted, or even the driver transistors. If the bias transistor(s) are damaged, Crown has none so you will have to look elsewhere. Some of the small signal transistors elswhere could be damaged or leaky too. Check to to see if a filter cap has shorted. Kinda rare, but it does happen. Good luck, and be careful
  12. CE4000 Input Stage Kaput?

    Bob, You may have lost an IC in the clock circuit. Without a proper clock signal the amp looks normal, but will not pass a signal. It all has to be in sync to work correctly. It is a simple fix but must be sent in to the factory Service dept.http://www.crownaudio.com/forums/style_images/1/folder_post_icons/icon5.gif
  13. CE4000 - KA-POW!

    Thanks for the response, though I don't know how this affects me, as my mixer and outboards are all run through the same conditioner in the same box with a single on/off switch. I ALWAYS power the board before turning on the amps. The input gain is always full-counterclockwise when powered on. Rel: since the original post I have not had this occur. None of my components has changed. I have also not run sound at the "contributing" venue. I suspect that their power may not have been as stable as it should have been. It's been well over six months and several dozen shows with no problems. None of the gear seems the worse or fatigued in any way, either. How odd. There are several small redundant surface mount capacitors on the bottom of the main board used for filtering RF from the supplies. It is possible that one of those have failed, which fails by exploding. If the amp is still working, you have nothing to worry about. The amp will run fine and remain in spec with several of these caps missing. Hope this helps! Then again, could be the amps way of telling you it doesn't like the music!! http://www.crownaudio.com/forums/style_emo...fault/laugh.gif
  14. Help with shorted out K2

    My first time for this forum, so please pardon me if I post something incorrectly. There is nothing more you can do for your K then to send it in for repair. If it is what I am thinking is wrong with your K, it will be a handfull of parts and less then 2 hrs of pain. (labor)
