  1. Hmmm, interesting. I need to go and check which setting I'm using. I guess if it doesn't hurt anything, I can try both, and see if I get more out if it with one vs. the other.
  2. I have a mono signal coming from a compressor (A Demeter HXC-1) driving CH1 of my crown. It is crossed over and feeds lows to 1 and highs to 2. I'm confused over the two settings - Input Y and CH1 + CH2. It seems I can't drive the amp to nearly it's full potential, even driving the compressor to max output. I believe I have it set for Input Y. Would I be better choosing CH1+CH2 and daisy-chaining the line output of the XTi's channel 1 to it's own channel 2? I read in the manual that using Input Y would give a 6 dB boost. The compressor drives other line level inputs with authority - I usually have to turn it way down. Apologies if this has been covered, I searched and didn't find... Thanks!
  3. Well, glad to know at least that I'm not overlooking something. Can I use Sys. Arch. with the XTi series?
  4. Posted this over in 'Software' but had no views, so I'm re-posting here. Am I overlooking the possibility to edit user preset files via Band Manager without being connected to the amps themselves? I'd like to be able to edit and change the settings on my saved pre-sets at some other time/place than at practice or a gig. Then be able to connect and sync/save/update the changes on the amp(s) as convenient. I'm not able to find a way to edit my saved files 'off-line' though, am I overlooking something? T.I.A.

  6. I'm not entirely certain about this, but it's an idea... The clip light measures distortion. It will light, even if there is 'headroom' left on the amp, if your input signal exceeds a certain amount of distortion or clipping. Your board, etc. may not be showing it, but if you are running it hard, it may be introducing a signal which clips prematurely. The common thread here is gain structure. Crown puts out some first rate literature on the very subject... I've read and re-read it all many times. The solution may be there as well.
  7. So far compared to my DBX 223 XL, there's no comparison at all, the digital settings of the crown allow for far more precise settings. You can very accurately set the notch of your crossover point to sum the output very linearly. I like using the butterworth on each end to roll off lows and extreme highs too, I think it works even better than a low filter setting.
  8. Is this @ me? It makes no sense, I think you might have two different posters confused...
  9. Sorry for the Looong delay - Jury duty... Anyway, here's my deal... I have two low end boxes. Each has a single 15" JBL 2226G at four ohms. They have a continuous program rating of about 600 watts. and a sensitivity of 98db. I also have a single box with two vintage 10" JBL E-110-8's. Each being 8 ohms, also with a sensitivity of 98db. I've wired the 2x10" box for 16 ohms internally. I've done this to keep it's volume per watt as LOW as possible, because these speakers just scream! The bass boxes I can wire externally in series for an impedance of 8 ohms, or parallel for 2 ohms. (nominal) My cross-over point is 80-90 Hz, which works best with my box tunings, etc. Looking at the specifications, this low cross-over point should also keep the woofers well over two ohms, because the 'most efficient' and lowest impedance point is at about 500 Hz with the curve being significantly higher at my crossover point of 80-90 Hz. The 2x10" cabinet is significantly 'louder' than the two bass cabinets - not so much as measured Db wise, but because one's hearing is more sensitive to the freq's this box is reproducing. Essentially, I have to reduce it's volume by attenuating as much as three-quarters of the full range on the channel. So, my wish is to be able to reproduce enough bass to keep up with the 2x10" cabinet as much as possible, rather than attenuating so harshly. I know that wiring for 2 ohms will yield more efficiency, and a little extra volume over 8 ohm wiring, I'm just wondering if it's worth the extra strain on the amp, lower damping, and higher THD. I'd rather run at 4 ohms, but short of a re-cone job which would cost more than the amplifier, I'm stuck with 2 ohms, or 8 ohms. Considering Impedance and efficiency as well as absolute volume, I'd like opinions as to which is best? Thanks
  10. I haven't found any information here about how the XTi 2000 will be "moderately annoyed by a 2-ohm load." or that in general we should avoid them. The load is published in the general spec's for the series, and specifically for the amp. This concerns me because I've never run a two ohm load before, but I just purchased an XTi 2k with the purpose of running a 2-ohm load on one channel. Can you point me in a direction to learn more? Why would Crown publish this spec if it were less than acceptable? The two ohm load (two 4 ohm JBL speakers) meets my power requirements, but wiring it for an 8 ohm load does not I will be using four strands of 12 Ga. wire, and my lead will only be about 10 feet. This falls well within the chart for acceptable current and damping factor, and it's for lows only, so I'm not as concerned about THD. I am also interested in running a 16 ohm load on the other channel, (Two 8 ohm JBL speakers) although this can easily be made a 4 ohm load. 16 ohms is not specifically stated, but conventional wisdom is that higher impedance is always fine. Is this true here? These speakers are FAR more efficient than the low speakers, hence why not use 16 ohms?
