Debating whether to go Pre Amp/Power Amp...Need help...

[Lowtonejoe]

So.... Do I need a xlr y-splitter from the output of the pre to the input of the power, and a cross wired speakon to run it bridged mono?

If by 'cross wired speakon' you mean a bridged mono cable, yes.

The XLR 'y' splitter will get your signal to both channels of your amp and the 'bridged mono' cable will get you power from both channels of your amp. Or get a +1,-1,+2,-2 splitter and run dual mono.

Or do I just plug the pre into the first channel and used the cross wired speakon from bridged mono? I'm so confused....Please set me straight on this...

I could be wrong but I don't think this would work and MAY cause damage.



Joe.

Ok. Thanks for the help LowToneJoe, and anyone else I might have missed.

To run the XLS bridged, my connections go like this:

Bass >
instrument cable >
preamp >
bayou crafted bridging y-splitter >
XLS 402 (feed both channels) >
bayou crafted speaker cable (use the ch 1 output) >
First GS112 >
normal speaker cable >
2nd GS112

Enjoy!

You dont HAVE to use a speakon - speakon cable to the first cab. You CAN use banana plugs to connect to the amp. I CHOOSE to go speakons on both ends, as a failsafe to keep me from fekkin up while setting up & potentially frying something.

BTW, to go dual mono, but you'll cut your output in half.

instrument cable >
preamp >
normal Y-splitter >
XLS 402 (feed both channels) >
channel 1 > normal speaker cable > First GS112
channel 2 > normal speaker cable > 2nd GS112

That is a great run down McHack! Thanks!

I prefer to go speakons, so that is what I will probably order. Thanks again!

Interesting. so I could run a 4 ohm load rated at 600w into one channel, and run an 8 ohm load from the other channel and have the same 600 watts, or different?

Just think of both channel as seperate amps.

If you put a 4ohm cab on one channel, itll get 600W.

If you put an 8ohm cab on the second channel, that amp channel will be running at 8ohms, and the cab will get whatever you amp does at 8ohms. (about 300W??)

As long as you understand impedances (sounds like youve got the basics sorted but there's the amp FAQ just in case) just think of channels one and two as different, seperate amps.

Sounds like youre going to bridge anyway.

Thanks Jack!
