y cables, are they dangerous

Honestly Im not sure in this particular application. One issue is will the XLR and RCA outs work simultaneously, my guess would be yes. But the stumbling block is that XLR outputs almost always are at a approx 4db higher output, and this issue would have to be addressed. Lets see what the other Agoners have to say.

Bigjoe, do you have an electronic crossover, or does the tweeter panel have a crossover built-in? You can damage tweeters by running a full-range signal into them without a crossover. At the very least it won't sound good, even if they're not damaged.

Generally, for biamping, the setup would be preamp to electronic crossover, then the crossover would drive each power amp. You wouldn't need a Y adapter.

wow, the plot thickens,luckily the khorns were allready set up for biamping when i got them,at this point im gonna contact roger russel( xrt22 designer ) & see what route he suggests.

mike.

it depends..... alot depends on the output stage of the pre and whether it can swing the voltage and impedence. i checked with the designer of pse if i could use a xlr splitter to biamp 4 monoblocs ( i have a pse hl-1 pre with 1 set of xlr outs ).

wether you can use xlr and rca together will depend on if the xlr stage is a true differential design and totally seperate from the rca stage.

if the xlr is wired off the rca ( psuedo balance like the arc ls 2b) then you cant use the xlr and rca together due to the phase shift.

hope that helps,
