  1. It's been a while since I posted here. Things have been going great with my XTi 2000 as the foundation for my high volume/outdoor bass guitar rig. However...something has come up that I need help with. Whenever I hit the note A1 or A#1 there is a buzzing-like vibration on the top case of the amp in the middle right behind the front panel. When I put my hand on the top panel in that spot the buzz/rattle goes away instantly. Would a vibration dampening sheet like the AudioQuest Sorbothane type affixed to the inside of the cover fix the problem? And if so, do I need any special tools to get the top off? Suggestions?
  2. Have you thought about purchasing your XTi from somewhere other than Guitar Center? I bought mine from Northern Sound & Light. Great folks to deal with. My amp worked properly out of the box.
  3. I finally got around to calling tech support this morning. I didn't catch the man's name, but he was very helpful. According to him, due to where the Y is located in the signal path, it is not possible to be able to use both channel 1 and channel 2 input sensitivity knobs independantly if your signal is coming from a mono source (like my Ashly SC-40). Only the channel 1 knob will be operating unless you use a jumper cable from channel 1 to channel 2 on the rear of the amp. The way he explained it made sense to me. I have no problem with that arrangement, now that I know. When I want the really big watts into one speaker cab, I run the amp in BRIDGE mode. When I want to hang speaker cabs off of each side of the amp and be able to adjust their volumes independantly, I set it to DSP OFF...CH 1 & CH 2 engaged (with a jumper). Works like a charm. I'm gonna go crank it up now!
  4. Thanks, Mark. Option 1 was successful. Option 2 would never be useful to me because when I run two cabs, they are always different from each other. Option 3 is my favorite...except that I can't get it to work. I followed your instructions along with the manual. Still no sound coming out of channel #2. I will take your advice and call tech support.
  5. This post is a repeat of my last post in the 'XTi unplugged' thread. My new XTi 2000 arrived. I'm suffering from a bit of frustration, however. I can get the unit to function in bridged-mono pushing one cabinet. I can't get it to operate in dual-mono pushing two cabs. I only need two things from this amp. The ability to operate in bridged-mono when needed...and dual-mono when needed. All the other bells and whistles will likely never be used. I'm using a mono preamp and understand that I need to get it into Input Y mode to run a cab off of each side of the amp. Here's the problem. I follow the instructions in the manual exactly, but can't seem to get it out of bridge mode with the select button. It will respond to the CH1 CH2/Input Y/Stereo command but will not accept the Bridge/Stereo command when I'm on the BRG icon. No matter what I do, the word BRIDGE returns and stays on the screen. Sound only comes out of the Channel 1 speaker output. I've double-checked my speaker cables and speaker cabs to verify they are in working order. And yes, I know how to hook up speaker cables to the rear of an amp. The front panel input lights show incoming signal to both channels, but there is no output on channel 2 and the word BRIDGE remains on the screen. To put a fine point on it, it seems like when I'm at a spot where I need the Sel button to select STEREO...it won't. Is the word STEREO supposed to remain on the screen when it's properly configured for Input Y & Dual Mono? What will the screen show if I'm in proper mode for running a speaker off of each side from a mono preamp? I'm not the brightest of bulbs, so maybe I'm missing something here. Any words of wisdom?
  6. My new XTi 2000 arrived yesterday. Amazingly, UPS did not trash the box it was shipped in. Suffering from a bit of frustration, however. I can get the unit to function in bridged-mono pushing one cabinet. I can't get it to operate in dual-mono pushing two cabs. I only need two things from this amp.

Any words of wisdom? Maybe I should start a new topic...'XTi Challenged'. Edit: That's what I just did. Please jump to that topic. Don't bother answering here.
  7. A new XTi 2000 is on it's way bouncing up and down heading west in a UPS truck somewhere. The website and online manual list output power at 1kHz. Can anyone tell me what the amp will put out in stereo per channel at 4ohms and mono-bridged at 4ohms, 20-20kHz? Also same question at 8ohms 20-20kHz?
  8. Thanks again, Mr. Glass. I'm sold. I just ordered a brand new XTi2000 for my bass guitar rig. We'll see how it goes.
  9. Thanks again, Mr. Glass. It does seem that you answered my question in your first post. I was unclear as to whether that applied to power being shut off at the front panel switch or by being unplugged from the wall. Looks like it is the same either way. Cool. One more thing...is the lettering on the XTi front panel silkscreened on or is it a piece of tape?
  10. Thanks for your reply, Mr. Glass. It's good to hear I can use the XTi 2000 just like an amp with no DSP. That is my intention, as it will be part of a bass guitar rig pushed by an Ashly SC-40 preamp. Since I plan to use the amp both in dual mono and in bridged mode depending on the situation at hand, what happens if I'm connected in bridge mode and during the gig the bandstand loses power for a few minutes? After power returns, will the amp remember the mode it was set up in last (either dual mono or bridged)? I sure don't want to be melting things if I absent-mindedly forget to doublecheck. Disclaimer: I am a bass player. And a question that doesn't seem to warrant it's own thread...is the lettering on the XTi front panel silkscreened on or is it a piece of tape?
  11. I read the online manual and did a search but was unable to come up with an answer to this specific question. When you unplug the amp from the wall, what presets will it retain? This question applies to using the amp right out of the box and not downloading System Architect software from the internet.
  12. Thanks for your help, Mr. Glass. M. M.
  13. I may have found partial answers to my question in other recent topics. Either the Xs series has variable speed fans that in low volume situations would be barely audible or they have 2-speed fans that are audible even on low speed? Which is correct? In what country is the Xs series manufactured? M. M.
  14. My first post. Hi y'all. I'm considering the Xs700 for my bass guitar rig. I did some searching on the forum before posting, but info seems limited on this model. There was some discussion of fan noise and that's my only concern. The amp would be used for louder gigs where fan noise isn't such an issue, but is the fan noise loud enough that you wouldn't want to use this amp in a recording situation? As a way to judge, in a quiet house can I hear the fans if I'm in the next room? Do the fans run all the time? FYI I would be pairing this amp with a like new Ashly SC-40 preamp bought back in 1982. Depending on the gig, my mood, or how the planets are aligned it would be powering one or two of the following; Epifani UL-410, Epifani UL-210, Aguilar GS-212, Ear Candy BassBomb 212 (all 4 ohm). I was attracted to this model because it's not too heavy, not too light, has no DSP capability, no USB ports, no bells or whistles. Just the right amount of dual mono and bridged mono power for my needs. M. M.
