  1. Hi, Every time i use a pip card, i end up running it at about +10db to +12db on the software fader. (i like to leave about 6db of headroom if possible) I think the PIP card attenuates the input to give you 20db of headroom, where as a non PIP amplifier is only attenuated on the rear gain trims. Hope this helps Rob
  2. Hi David, Go here http://hiqnet.harmanpro.com/sa_download.php (You may need to log in) It is the System Architect downloads page. Scroll to the bottom of the page and there is a section on the Crown CDI,XTI and DSI amplifiers explaining the 'pre 2006' firmware, select the 'firmware update can be downloaded here' option. Run the software with no other HiQnet apps running, update the amplifer, then launch SA and add any additional firmware updates. Enjoy Cheers Rob
  3. no body has an answer for me? Not just you man I keep putting stuff up and nothing. Email customer service - Hey it's Christmas, and this Forum is not technical support - it is a voluntary user group that Crown monitor, and when able will reply to. If you have urgent technical inquries, call the technical support or local country distributor for advice. Cheers Rob
  4. Thanks for the detail - why would they sell a speakon cable that isn't setup correctly? What do I stand to gain by your adjustment? Hi, There are a number of different ways that the speakon outputs can be used. If you look at the labelling on the back of the amplifer, in stereo (2 channel) mode: Speakon output 1 is wired so that 1+1- will be channel one and 2+2- is channel two. This is so that you can use one 4 core speaker cable to bi-amp a speaker system. Speakon output 2 is wired so that 1+1- will be channel two and 2+2- is not connected. In Bridge mode, the amplifier channels are 'joined' together to produce double the output of a single channel. In this mode the amplifier outputs change so that 1+ is used for the speaker positive terminal and 2+ is used for the speaker negative terminal. If you have just been using the amplifer in bridge mode and using the 1+1- outputs you will be not getting proper performance at all. Normally a patch panel is used to do this 'cross patch' so that the speaker cabling can be left at a standard 1+1- configuration. The wiring from the amplifier to the panel will be 1+2+ at the amplifer and 1+1- at the panel socket. Only channel one attenuation should be used in bridge mode, the amplifier 'links' the channels internally Hope this makes sense Rob Hi Rob - thanks very much. Yes, that does make sense. I wasn't aware I needed to change the wiring with the speakon end...So the wiring for the rest of my setup at this point is correct? I curretnly run a speakon from one sub to the other and then out of that sub to the amp. At this point I'll need to adjust the wiring only in the cable i run from the sub to channel 1 in the amp, right? for the amp i'm running in stereo, i can continue to wire them as I have been. channel 1, channel 2 each to their own speaker. again - thanks so much for the help. really weird as i've been runnign this set up for a while. Found this: http://www.crownaudio.com/pdf/amps/126986.pdf Hi, The MRX single 18 is 4 ohms. If you are running 2 of them it is 2 ohms. You cannot bridge down to 2 ohms. Minimum is 4. Why are you running BM on the subs? The MRX are a 600 watt driver so you can run each amp channel to one sub, parallel the inputs of the amplifier. Job done.

  6. Hi There, So the MRX are rated at 600 watts, you do not need to run the XTI 4000 bridge mono. Running the XTI into a 2 OHM Bridge load is only going to lead to the amplifier overheating. The XTI 4000 is rated at 1200 watts at 4 ohms per channel, more than sufficient for one MRX518 per channel. So i would run one sub off each channel, and Y the inputs if you want to use a mono Sub. The XTI has a built in crossover, so you can use that. What you should do when you set it up though is adjust the gain structure so the signal in and out match. Use band manager or system architect to set the amplifier up. As you are crossing over the signal, there will be a lot less going out than coming in. So once you have set the crossover (start at 30HZ LR24 and 100HZ LR24) play some music and move the crossover gain up until the Input and output meter are similar. You will now have maximum gain through the amplifier. A driverack PA will allow more limiter settings to be set, and will allow more control and EQ of the EON Speakers if you want to cross those over at 100HZ. I think if you do the above for your subs you will find there will be more than enough sub! Let us know how you get on. Rob
  7. Hi, When running an amplifier in bridge , you are inverting the channels of the amplifier so output is derived off 1+ and 2+ on the back of the amplifier. You need to wire your speakon accordingly, or use the banana plugs. The back of the amplifer speakon socket on CH 1 allows 1+ and 2+ to be selected. A 2 core cable is sufficient for BM operation. thanks Rob ========================== What about the speaker end? Do you have to rewire that too? This is still not clear to me... If a 2 conductor cable requires rewiring (because the 2 wires are running on 1+ and 1-, thus needing 1- to be switched to 2+) wouldn't a 4 conductor cable already have that step taken care of? As Logruvz said, what about on speaker side? Sorry to be a pain. Just want to make sure I am not incorrect in my setup and I am getting full power to my speakers. Hi, You will nee to wire the cable as follows for BM: Amplifier 1+ - Positive signal Amplifier 2+ = Negative signal Speaker 1+ - Positive signal Speaker 1- - negative signal. So you can either make a cable wired 1+2+ and 1+1- Or you can use a patch panel on the amplifier rack that has this 'crosswire' and then have a normally wired 1+1- speaker cable running from the amp rack to the speaker. As the speaker is not running biamped, then you only require a two core cable Hope this is clear. Kind regards Rob

  10. We have used this before http://www.digi.com/products/usb/anywhereusb.jsp Allows you to sit the USB Anywhere on an ethernet network, and run Cat 5 from FOH to the Amp Racks Works well. Cheers Rob
  11. 2.66 Ohms - remember this is nominal.....(I.e. dependant on frequency, so check the speakers impedance curve for the frequency you are reproducing with the driver to see if it will be higher or lower)
  12. Hi, On page 7 of the manual it explains how to hook it up. Go here http://www.crownaudio.com/pdf/legacy/125645.pdf Either use a 1/4 inch unbalanced connector, or if using an XLR then pin 2 is hot and 1and 3 need to be joined as the cold/ ground. It will work with no problems. Just be aware that unbalanced cables are more prone to noise (buzz etc) picked up by external sources. Enjoy Rob
  13. Hi, So they were running AMP 1 CH1 - SRX722 (1600 watts at 4 ohms - amplifier rated at 2000watts at 4 ohms) CH2 - SRX728S (1600 watts at 4 ohms - amplifier rated at 2000watts at 4 ohms) AMP 2 CH1 - SRX722 (1600 watts at 4 ohms - amplifier rated at 2000watts at 4 ohms) CH2 - SRX728S (1600 watts at 4 ohms - amplifier rated at 2000watts at 4 ohms) All processing is internal in the amplifier for crossover, EQ and limiting. Left main mix would feed to amp 1, CH1, Right main mix to amp 2 CH 1. Input Y the amps, job done
  14. Are you running the latest firmware. Band manager will only recognise amplifiers that use System Architect 1.90 firmware. You also cannot use band manager and system architect at the same time - only one or the other at once.
  15. Hi , Please confirm Vista is 32 bit Your version of system architect is 1.90 Amplifiers are running the latest firmware (available with System architect 1.90) This forum is for non urgent enquiries. Crown technical support staff are available either from your local distributor or from the crown contact details on their support page.
