QSC RMX and IMG Stageline LS-280/SW

Hello.

Looking for some help as I am helping a friend and I'm very rusty!

He has just got a venue with 5 x ceiling mounted ceiling KEF speakers which look like they will take 100w at 8ohms

The amp was stolen from the venue but they have one of these IMG Stageline LS-280/SW line splitters to feed the speakers:

I was wondering if a QSC RMX 2450 Amp would be suitable to run this set up?
That will give 8 Ohms at 500W.

I would get a multi zone amplifier.
Below is just an example.

The line splitter isn't useful here, it splits line level signals not speaker level.

Are all the speakers in the same room or separate rooms, and do they need separate level controls? At best a 2 channel amp is capable of powering 2 zones, if they need more zones then need more amp channels.
For those speakers an amp that generates 200-250w/ch at 4ohms and is 2 ohms stable would suffice, so an RMX850 would be plenty.

Thanks for this - all the speakers are in the same room but some volume control between them would be nice but not essential.

I wonder what they were using the line splitter for?!

It goes before the power amplifiers so if they had a multi channel amp it could have been used as a volume controller for each speaker. You could still use it with a 2 ch amp of course but there is no way to get the same amount of control.
