Just got one of these second hand but cant really find much info on it. Could anyone tell me how the bridge mode works.. is it all controlled by channel A and i use a standard speakon or do i need to make up some cable to go between A and B?  also would it manage 4ohm in mono bridge?

if you search on google it says it does 2x750w @4ohms so i guess it will only do 8 ohm bridged

str3000 does 4r bridge, but if you search that i think you only find power ratings for 8 and 4r stereo.

Are you intending to bridge this on sub to play a gig?

Is there any reason to lead you to think this small amp could survive that?

Have had many of the matrix models, and would not recommend bridging "this one".

It's a small amp, not 2 ohm rated, and for good reason.

This "maybe" why a lot of the STRs for sale recently had just come back from repairs.

I would leave bridging on sub for the strongest of amps, which "usually" state 2 ohm stereo output, and have transformer/output transistor count to match.

hi to do this you need to put the amp into bridge mode before turning on  run your input into channel a ans make a lead to do this take a normal 2 post speakon lead and 1 extra speakon end wire positive to plus 1 in 1 connector mark this as positive this gos in channel 1 on the amp then place negative into plus 1 in the second speakon conector connect to channel 2  there ya have it 
do not bridge into 4 ohms
Wouldn't it be great to do a world wide link up?

If it helps, we've had the 15002u's which I believe are a very similar amp bridged into 8ohm to drive some drum fills and they were plenty happy. Sub however, I would not attempt.

Thanks for all the advice. I was going to try it  bridged on subs but it sounds like i should play it safe and put it on mid duty. I may try it in 8ohm bridge on one sub (quietly) for a test at some point. I just couldnt resist the thought of having a matrix amp in my rack for 100 squids! cheers all
