Thanks guys for all the useful info. I'm a new member and had this problem linking my two PSL KA2400's and losing signal on the second amp. Now I think I'll be able to sort it out.
THANX THANX THANX!!!

Also jacks can short out when you plug them in
Not great if theres power on it

If you have too much trouble linking the amps just make up some xlr Y split leads.

eeek ... moral of the story? Dont use mickey-mouse desks :) last big desk I installed (which admittedly was a while ago now) was an AMS 'gemini' digital thing with flying faders, no insert points to worry about, everything was done in the software ... takes all the fun out of it if you don't get to wire jackfields up to Krone frames :( |

If its a single jack doing send and return, how would you get it balanced? Or is there such a thing as TRRRS? Or are you simply suggesting they should provide a TRS socket each for send and return?

seconded on that. All decent outboard gear will be balanced in/out anyway :) seperate balanced send and return is far more flexible, because you never know what you will want to send it to, and how you might want to loop it about before it comes back to the channel. there is possibly an argument for unbalanced combined insert points on guitar amp heads, because you don't want to confuse guitarists with sockets labeled "send" and "return" .. they just stare at them and miss the first set. |

Guys -
Okay, going back to this amp linking thing...because i was looking at buying a speaker management system like the BBE DS26, found here http://www.bbesound.com/products/speaker-management/index.htm .
I have a Behringer EP2500 now, and am getting ready to purchase two EP4000 to run my subs, and i want to link the sub signal out of my crossover to the sub amps. The Behringer doesnt have a link plug, or does it? The back of my amp looks like this...
So, if I understand you all correctly. To link any amp, I can take the cable from my crossover and plug it into input #1 on amp#1, and then run another cable from input#2 on amp#1 to input #1 amp#2? Is this correct?
Thanks

No. Input 1 and 2 are two separate channels on your amp and are not linked inside the box. Connecting your sub signal to input 1 will not make it appear at input 2 of the same amp. You have two inputs per channel on the amp you linked to a picture of (1 XLR, 1 jack). They ARE linked inside the box. What you need to do is (read carefully) take the cable from my crossover and plug it into input #1 on amp#1 (e.g. XLR socket). Run another cable from the second input#1 (e.g. jack socket) on amp#1 to input #1 amp#2 (XLR or jack, doesn't matter). Et Voila. |

"my crossover" should read "your crossover" in my post above.
