I just put together a new, smaller, light-weight PA for my bar-band. Included in my new rig is a single XTI-4000, and I got some questions regarding the built-in crossover and how to hook up the speakers. Everybody seems to be doing all sorts of things with these amps...but I'm just looking for a traditional mains/subs arrangement. Here's my quesions....
1. I can drive both my mains and subs from one amp, right?
2. I assume this means a single mono-output goes to the subs, and the other output to the mains, right?
3. If so...what is the minimum ohm limit per channel?
4. Does the XTI automatically split power 50%-50% in a two-channel arrangement?
5. If not...can I control how the wattage gets split?
I'm running (2) 4-ohm Carvin towers for mains, and (2) 4-ohm Carvin 18" cabs for subs. Mono outputs are fine...but there is only one per side. I'm concerned with daisy-chaining the speakers and running a 2-ohm load on each channel. With my past PAs (old school analog stuff)...this was always a No-No. Also, I would like to split the power around 30% HF and 70% LF, if possible. I'm guessing most guys control the HF and LF volumes with the knobs on the amp but, I was wondering if these amps were somehow "partition-able" via the software, rather than just turning down the main (HF) side with the knob.
Not sure the exact wattage I would have with this arrangement...I'm probably a bit light on power for driving the 18"s.
ANY HELP OR ADVICE WOULD BE APPRECIATED...Thanks-DSPtarded
