  1. I have multiple XTI 4000's with the same ID #. I am able to use SA when using 1 amp at a time, but, I can not use multiple amps in SA due to this problem. This is not an address issue, they all have different address's. ID's come up with AA000FFFF for multiple amps. SA version 1.9. Firmware 1.1.5.6.
  2. Just wanted to let people know that CROWN customer service has been great the last couple of weeks. We have 18 XTI 4000's in our rental inventory and we have had the misfortune of 8 of them going down. I can't say enough about the quick repair turnaround and the outstanding customer service they have provided in this trying time.
  3. D Glass, We now have 18 XTI 4000's in our rental inventory. After reading the threads here, and other forums, on the net about the ongoing problem with the XTI amps and the signal lights showing up to -10db signal with nothing plugged into the amp, I have been keeping a close eye on our inventory. Wouldn't you know it, I had 3 (in one rack) act up this weekend, 2 in another rack, and 2 in the third rack. That is 7 amps out of 18 showing the same problem. Two of these amps were using the stock Bridge Sub mode, 2 were using NO DSP mode, and 3 were using custom settings for a JBL SRX 712M in bi amp mode. I think CROWN needs to take a serious look at this on going issue.
  4. Can anyone explain to me, how can it be, that the xti 4000 has much more power then the MA1200 and it cannot compare to it? 3992[/snapback] the XTi was designed for light duty. Bar bands, Small setups, etc. The MA was designed to be a work horse, Take Road Abuse, and hold up in heavy use better. 3994[/snapback] We now have 14 of the XTI 4000's in our rental inventory and I am waiting on our next shipment. I have nothing but GREAT things to say about this amp. They power everything from a JBL SRX 728 (bridged sub mode) to a JBL SRX 712M (bi amped or passive ***HOW COOL***) and any of our VRX boxes. Awesome power, light weight, and DSP. This is a great amp for the money.
  5. No internal revisions are on the horizon. The only thing to take into consideration is the software isn't released yet but is supposed to be soon but since you are using a DriveRack that probably will not be an issue for you at the moment. 3877[/snapback] Hey guys, The XTI 4000's are rock solid. I have been using them for 3 months now and have not had an issue. They have been through rain and dust. Recently did a show under a bigtop tent that was placed on a dirt/gravel parking lot. Still cleaning the gear. LOL. I would recomend this amp to anyone that would listen. I have been PATIENTLY waiting for the software myself. I know that when I am able to use the internal DSP it will only get better. Hey Dave, I ordered 6 more and have been told not until August. Can you help a dedicated customer out?

  6. No, you will not hear a difference between using the Channel1 + and the Channel 2 + of the banana plug/Binding Posts and the Pins 1+/2+ of the channel one Speakon connector as they are the same connection. What I was trying to explain is the Channel 1 output Speakon has both Channel 1 and channel 2 outputs on it. Pin set 1+/- has amp ch1 and Pin set 2+/- has amp ch2. By wiring the amp end connector of a speaker cable to use Pins 1+ and 2+ of the amplifier's Channel 1 speakon connector you can do Bridge-Mono without needing to use the Binding Posts. The the other end of the cable, that attaches to the speaker, would still need to be wired the standard way 1+/- were 1+/- are the same cables that are attached to 1+/2+ at the amp end connector. This can be seen in the diagrams found in the document links provided. If you were to uses a stand wired Speakon cable (were it was wired 1+/- on one end to 1+/- on the other end) and the amp was set for Bridge-Mono the cable wouldn't be connected to the right set of pins on the amp’s Speakon and you wouldn't get full Bridge-Mono power. Effectively you would be grounding one side of the speaker and not getting the other half of the signal that is on the other channel. This would basically be the same thing as only having the speaker connect to one amp channel worth of power (1200w) not both as you would for Bridge-Mono (3200w). The connecting across I was talking about was the speaker. When you hookup a speaker you connect it across a certain set of output terminal. For standard two channel operation you connect the speakers “across” a particular channels + and - output. For Bridge-Mono you need to connect the speaker “across” the amplifiers Ch1 + and the Ch2 + outputs. This Bridge-Mono connection can be achieved two ways the binding posts or the amplifiers Channel 1 Speakon output. Do Not put a jumper across any of the positive output terminals of the amplifier especially if you are in Bridge-Mono mode. Since in Bridge-Mono mode Ch2 is out of polarity with CH1 they will cancel each other and you will get nothing. Besides I don't remember saying anything about a "14 gauge jumper"????????? 3645[/snapback] Thanks for all of the info. Your detailed info helps. It is back to the drawing board though. As I stated in the beginning, there is NO noticable gain in the output on the sub when I use 1+/2+ binding posts for output. You have hit everything on the head as far as my setup. 12/2 speaker wire (not 4 wire), NL4 on speaker side(wired 1+/1-), banana on amp side, and amp set in bridge sub mode. I can flip the banana from bridge outs to CH1 or CH2 (which should be 1/2of the power 1200 watts versus 3200 watts) and there is no change. Thanks. 3647[/snapback] Found the culprit. Bad cable from audio source. Used them in bridge sub mode on JBL SRX 728's for a Hip Hop show. UNBELIEVABLE LOW END.

  8. Thanks for the detailed explanation. I am using banana plugs across 1+/2+. Are you saying by using an NL4 wired 1+/2+ I would see a difference? Or are you saying I need to use a 14 gauge jumper across 1+/2+ on the bananas and then use CH 1( 1+/1-) as the output for the sub to get the maximum output?
  9. What am I doing wrong? I am trying to run a JBL SRX 725 in BI AMP mode with an XTI 4000. I want CH 1 to run the 15"s and CH 2 to run the horn. I am using the DSP and X over at 1200. I have tried an NL4 off CH1 output and I have also tried Bannanas off of CH 1 and CH2 to an NL4. Nothing I do lets me have control of the horn. The only thing that functions is CH 1. I have tried the Y input, the stereo input, and the CH 1 and CH 2 input with thw same results. I eam also trying to run SRX 728's with an XTI 4000. The only way I seem to be getting any results that I am fairly happy with is by using the Bridge Sub DSP. In this mode I notice I can use the outputs as CH 1 and CH2 or across the two positives for a bridge out. Is there any advantage to using one over the other? I am not noticing a big difference in output on the sub.
  10. Can you tell me how to get the XTI amps into the devices sreen of HiQnet? Ihave installed the software and connected the amp with a USB cable and can not get the program to recognize the amp.
