XLS 1500 X-Over Settings
Posted 03 January 2013 - 12:50 AM
Forgive me, but this is a little new to me. I have a XLS 1500 amp that I am using to power 1 Peavey PV118 Sub(400w Program Power 8ohms). I currently have the amp setup in Crossover Mode(Input Y XOVER) with the sub connected to channel 1 Bannana Plug. If this is correct, what freq. crossover point should it be set at? Does this setup provide 300w to the sub other than the bridge mode of 1050W(which I take that I should not use). I just want to make sure I am getting the most out of the sub and I'm not overdriving it. Also, I have another amp that is running my mids/highs speakers. This is being using for a dj setup coming out of a Rane TTM57 mixer. Appreciate any suggestions.

To figure out how you configured the amps working mode it's more important to know how you connected the speaker to the amp, did you use the "Bridge" type of connection (page 4 on the manual under "Bridge-Mono Mode") or are you using a regular/unmodified speakon cable?
Do you have a crossover other then the one in this amp for the tops?

I did try to bypass the amps crossover, but the subs internal crossover just doesnt seem to cut out much mids/highs, that's why I am using tha amps crossover. Does this setup Crossover Mode(Input Y XOVER) seem like the best way to run the sub? If I run the amp in bridge mode, wouldn't that be way to much power, and possibly blow the sub?

I am not using this amp for anything else. Just for the sub. Is this ok? I have a different amp that I am using for the tops only. Is the Crossover Mode(Input Y XOVER) going to be ok for this purpose. I am using 1 input to Ch.1 on the amp(nothing connected to ch. 2 input). I am using the ch.1 bannana output of amp to go straight to my sub. I do not plan on connecting anything to ch.2 output.Is this setup giving 300w to my sub?

Using the amps internal crossover makes allot of sense, but you also need a crossover for the top speakers as well. If you don't have one and can't afford one, I would use the internal crossover of the PV118 and use this amp to power the tops using its highpass mode which is very close to what our friend Deromax suggested.

You can set the gain on the sub amp to any level that gives the sound you're after! It may need it actually, as a single 18 is not much subs compared to the dual 15 you have in your tops. You may want to look for a second PV118 sub some day!

To get that "umph" you want it would start better DSP (a different amp (such as the XTi 2 series) or an external processor (such as the DriveRack)) so you can separate the peak power from the continuous power, it might take bigger amps and subs and even stronger better tops but lets not get carried away here
About two 15"s Vs one 18", although cone area helps, it takes more then that to make good bass reproduction (or a good sounding sub), you need the box and driver parameters to be bass oriented.
