Do you mean that when the Bluetooth receiver is connected to the Beosound,or when it's connected to power?

It might be rf interference that's confusing the Beosound ir system?

Can you get the Bluetooth receiver further away from the Beosound to see if it makes a difference?They don't usually give you very long lead's with these kit's though?

Thank you for the good suggestions. The IR reception works fine if the Bluetooth receiver is wireless connected to a device, but not plugged into the Beosound even if still placed in proximity to the Beosound. I have now tried a longer DIN-mini jack cable - same IR interference occured. I also tried to place the Century and Ouverture next to each other and connect the Bluetooth receiver to the Ouverture - IR reception was fine on the Century then. Finally I tried another Bluetooth receiver (Argon BT2) on the Century connected with the same DIN-mini jack cable - IR reception was fine. So it seems that the Hall Audio Bluetooth receiver sends something through the AUX of the Century which disturbs the IR reception.

There are in fact data link connections on the aux socket of the Century,but it doesn't seem as though there is a cross connection in the Din plug,as this would affect operation with the Ouverture too?

Have you tried connecting the Din plug to the Century,but disconnecting the mini jack from the BT receiver,to see if the problem remains.

Does the mini jack connector have three connector band's or four?

It sounds like that particular BT receiver is putting hash (aka electrical noise)  on the audio outputs that is getting into the IR receiver circuitry of the Century, especially since it works with a different brand of BT receiver. If so that's a very poor design or a bad unit. Would be interesting to put a scope on the outputs and look for noise.

The mini jack has three bands and works fine on the Century with all other mini jack equipped audio sources I have. Definitely it could be interesting to test the Bluetooth receiver with a scope, but I don't have access to one. I have now contacted the manufacturer of the Bluetooth receiver and am looking forward to their explanation.

The manufacturer kindly replaced the unit, but unfortunately it didn't solve the problem. So it seems there is a general incompatibility of this particular model's line signal with the BS Century as suggested above. Do you have suggestions to another small-sized Bluetooth receiver I could try for the Century such as Chrome Cast Audio?

Hi rrm,

Chromecast Audio or Apple Airport Express are much better options than bluetooth, as they can use wifi for better sound quality and wireless range, without causing interference issues.  A simple cable will connect either of these devices to the Century Aux socket:
