Adding room correction to Essence+BL3+BL11 setup?

My setup is a BeoSound Essence MkII into Beolab 11 and from that into a pair of Beolab 3's. I would like to add a room correction device (a DSpeaker Anti-Mode Dual Core 2.0), but am not quite sure how to do it. Would anyone be able to help?

The DSpeaker only has RCA or XLR inputs and outputs (as well optical, which is not really relevant in this context). Currently signal from the Essence goes to the BL11, which does its internal bass management (I guess this means a crossover?) and then forwards the signal to the BL3's. Both the BL3's as well as the BL11 are in PowerLink mode.

My assumption is that I should place the DSpeaker between the Essence and the BL11. For this I would need a RJ45 PowerLink to RCA cable from the Essence to the DSpeaker and then an RCA to PowerLink DIN cable between the DSpeaker and the BL11. Is this correct?

If the above is correct, would I need to set the BL11 to Line mode instead of PowerLink mode? Should the BL3's also be set to Line mode? In this setup, would the BL11 still be able to do its internal bass management? And forward the left + right signals to the BL3's correctly?

I would be really grateful for assistance!

 

 

 

 

 

You are contemplating a real mix & match.

And may end up with a unique installation.

Unique as in risky !

I believe the new unit would have to be between the Essence and the BL11, but does it have stereo+subwoofer output ?

If so then all speakers would be line in mode.

Otherwise only the BL11 would be in line mode, as the other speakers are downstream.

However you need to ask / research carefully to make sure the device's calculations / adjustments would be relevant in a B&O world ....

Thank you for your response.

No subwoofer out on the DSP, just stereo jacks. But I think it is actually good news that I would not need to adjust the BL3's, just with the BL11 into line mode and swap the incoming signal cable. This makes trying the DSP significantly easier. Of course, if it does not work then it will be easy to remove again and continue as is. As for the cable between the DSP and the BL11, I wonder if it needs to be a RCA to 7-pin DIN PowerLink or will a RCA to 5-pin DIN PowerLink do just as well in this context?

 

 

 

Sorry but I don't know if 5 or 7 pins are needed.

The beotech sister micro site has wiring diagrams that might help you.

Or reach out to Steve at Sounds Heavenly -- he helps sponsor this site so one good turn deserves another don't you think?

I already have the 5-pin one, but apparently I need the 7-pin one. So I ordered one from Sounds Heavenly. Thanks!

Ok. The RCA to 7-pin DIN arrived and the system is now playing through the room correction. The connections and settings are exactly as concluded above.

My listening room apparently has a fairly broad hump as it boosts the frequencies from 120Hz to 160Hz by between 3 and 5dB. This boost is completely flattened by the room correction. Other anomalies are also corrected while the deep (but fortunately very narrow) suckout at 66Hz is left untouched. End result? Early days, but the bass sounds more articulate and less boomy. Overall the sound seems more airy with clearer soundstage. So far I hear no negative effects even though the DSP does an extra AD and then DA conversion.
