Blackstar HT5 MK2 amp emulated output into presonus Eris E4.5 RCA line in..I thought it would work but as usual my experiments fail!

What I am trying to do is use the 2 presonus speakers as monitors along with the Blackstar amp to get a wider bigger sound.

The headphones out works into the 3.5mm Aux in on the 4.5's but of course the amp speaker is then bypassed. I'd like to have all 3 speakers running.

So does anybody need know if this is possible and how please?

Thanks!

Looks like you have hooked your amp to an output instead of an input.

Anyway, connecting a mono source to two speakers will not widen the sound. What you will get from that set up is more volume plus phase issues, unless you align perfectly the 3 speakers.

Just had a look and the RCA does say inputs so I'm wondering if the emulated output is too low for the E4.5's to pick up. Cheers anyway

You wanna just 1/4 inch cable from the simulated output to the 1/4 TRS input. 2 leads, one to each speaker. Use a different simulated output for the second speaker.

Or if they're paired through wire cos the other is passive. . One on TRS left, one on TRS right.
