B&o speakers and Avr from Denon with Pre outs

[Frode Hansen]

Trying to connect 6 beolab 1 ,and a beolab 7.2 in a surround setup using my denon avr`s pre out.
using mk3 cables for the all beolab1 speakers and mk2 for the 7.2 speaker.
the trigger cables are placed with the avr .
Problem: a slight noise in the beolab 1 speakers and more noise in the 7.2 .

changed the trigger cable for the 7.2 to a type with usb instead of the mini jack that pluges directly into the denon.   that did help alot , but still some noise.

 

It seems the noise is mostly from the denons trigger output (bought a filter,but did not help) , so my question is :
will it be better to run coax rca from pre outs directly to where speakers are placed – in to trigger cable there and then in to speaker.?

will connect a smart relay to trigger out on the denon and a smart relay where the trigger cables are. they will then activate when avr is on.

will this help with the noise ?

I had this problem. I removed the one cable inside the 3.5mm.
you can also use this adapter

That is the filter I bought also . But still some noise .

what cable did you remove inside the 3,5?

I think it is the grounding cable. So it is same as the one you bought.
you could try to use a mk3 cable on your bl7.2, and a mk2 on your bl1, just to see if it makes a difference.

im not sure if you have used the ice powered speakers before, but they tend to have a small brucing(?) sound when silent.

where did you get your trigger cables?

Seems to be more noise with mk3 on the 7.2 .

with shorter cables (2meter) there is absolutely no noise in 7.2 (mk2). And beolab1 (mk3) .

trigger cables from av-connection .

this is why I was wondering if it is better to mowe the trigger cables to the speaker location and use rca coax from avr to the trigger cables .   There is at least 12 meters from avr to the furthest speaker.

I am thinking the coax cables is less likely to pick up noise ?  So if someone knows if this is a better solution or have something else that could be better I would like to know 😊

You could try with a ferrit and see if that would helps.
