  1. Those speaker are 4 or 8 ohms? how did you plug them parallel or serie, http://www.crownaudio.com/pdf/amps/139921.pdf a XTI4k at full blast(severe clipping) can draw about 15 amps in bridged mode 4 ohms @ 230 volts (read same as 2 ohms stereo figure). also, daisychained using speakon, which i believe to be parallel Hi, The speakers I was running were 8 ohm each so 4ohm bridge is what the amp was running at. It would've been at full blast. How can I draw this much power without using up to 15amps? Surely there is a way around this because there are more powerful amps out there that run on a simple mains supply. Thanks

  3. Hi, On my last event I ran my XTi 4000 in bridge mono mode pushing a pair of power hungry 1000w RMS Fane Colossus-18 1000 subs in EV T-18 cabinets. For some reason, an hour into the night the amp switched off. I changed the IEC cable and found that it worked for another few minutes and switched off again. In both cases the amp blew the 13a fuses that were in the power plug going into the main socket (240v). Is it possible for the Crown XTi 4000 to draw more than 13 amps in this way? What can be done to prevent this happening? Thanks, Manni
  4. So I have an XTi 4000 and it is presenting some problems... FIRSTLY... I have noticed that one of the channels cuts out when playing even at low volumes (see my youtube video)... http://www.youtube.com/watch?v=41Y0uBZfzWw&NR=1 Switching off the amplifier and back on again fixes this. Does this mean it is a problem with the display board/ribbon? It was manufactured in August 2007. SECONDLY I was testing my new crossover (I know the XTi has a built in one but I need this for my QSC GX5) and I had a low pass filter at 100Hz going to the Crown XTi powering one T18 bass cabinet with an Electrovoice DL18MT driver. During my test the Crown Amplifier cut out completely - the display panel went blank and it just looked dead. Should this happen? Even if the amp clipped because there was too much power going to the sub, shouldnt it just go into a safety mode or is this normal? THIRDLY (and finally...) I thought I'd try updating the firmware using the latest version of System Architect to see if this would change anything. While connected I was keen to try out the DSP features - but I noticed that one of the channels was acting as though it had an input and it was moving slightly on the display on my laptop screen (i think it was the problem channel, channel 2 again), as though it was some kind of noise. My XLR posts were empty at this time so there was clearly NO input coming into the amp. Surely this shouldn't happen right? Do these symptoms suggest anything obvious? Are they likely to be interlinked problems or one single (hopefully known) issue? Any help would be much appreciated. Thanks, Manni
  5. Hi, I'm a fairly new Crown user (have always used QSC) and I really like the DSP features on the XTi amplifier. I'd like to tweak the features in System architect to make the most out of my Electrovoice Sx300 speakers and if possible my Electrovoice T18 Cabinet with EV DL18MT drivers along with my EV Force i 18" Subwoofers. I use these in different combinations so want to set up different presets for different scenarios (which I know how to do) but I'm just unsure how the eq and crossovers should be set for these speakers. Are there files available which I can just load into System Architect which set the ideal settings for any of these speakers (most importantly the Sx300). Thanks, Manni

  8. Did this fix the issue? I have the same problem with my crown XTI amplifer and have posted a video on youtube which shows the problem (http://www.youtube.com/watch?v=41Y0uBZfzWw&NR=1). I had troubles trying to get sound tech to fix it but are now going to take a look at it - sending it to them today. A crown techi in the US told me that there was an issue with the earlier models of XTi amps where the display board had a faulty ribbon or something, which caused this to happen. Is this what they changed on yours? Has it ever done the same thing again? I'm worried now that my amp will never be the same again
