  1. XTi 2000 & XTi 4000 - Suggested Settings

    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. Ok - so right now I'm not actually running the inputs in parallel - which I should do. I've never actually altered the input settings since I first started using the XTi series amps. I run out of the mixer to a BBE and then into the amp/s. So I can select the "Y" function in the settings of the XTi. Would I continue to wire the subs together in the same way as I am now (one into the other and then into one of the outputs of the amp) It think I can run a 2ohm load in stereo... Also, I wonder if the same can be done with my EV's into the XTi 2000 (paralleling the inputs). Sorry for such newbie questions - I've done this kind of stuff for a long time and its STILL confusing as *beep*.

  4. Hi - I've been running both the 2000 & 4000 for a couple of years. I run the 2000 to EV force series 15" (2) and the 4000 to JBL MRX 18" subs. I run everything through a BBE maximizer as well. The sound quality is good, but I can't help but wonder if it shouldn't be better. More bottom end end the subs, less tendency to clip, etc. I running the subs in BRIDGED mode but not using the sub-synth feature. I'm wiring the subs parallel, and into Channel 2 on the XTi4000....which may be incorrect as I recently read that Ch1 was for low frequency drivers by default.... The Mids/Highs are being ran in stereo to the XTi 2000, but I could possibily benefit from a different DSP setting for them, EQing, etc. I guess what I'm asking is, does anyone have a suggested setup that they go by? (DSP settings, wiring configuration, etc.) I use speakon connections. This is in a mobile dj setup. Any tips would be great and MUCH appreciated!! Justin justin_lacher@yahoo.com booking@thinkjalan.com
