If you want the music from the Mac Mini playing on the whole system you could connect it to the AUX connection on the Beosound Ouverture. however if the AUX connection is already in use fo other equipment you can use the 1612 to get an extra AUX connection (the connector labeled AAL) that is activated with video commands (TV, V.MEM, DVD etc). This however require you do not have any B&O tv’s in the rooms as this would make conflicts in operation. The PC input on a Beolink Active will only play music in the room with the Beolink Active, so might not be what you want. Hope this help you on the way

I tried to use the AUX connector but the volume was very low.  I was hoping using the 1612 would remedy this issue.   Do I need any specific cabling???   If so where would I acquire it??   thanks.

When using the Aux connector the volume of the Mac Mini should be set relatively high. You should be able to use the same Aux cable with the 1612 when used as a video source. Masterlink cable between the 1612, Ouverture and link rooms.  If that also has low volume the AUX  cable could be configured wrong (output instead of input)

Ok that sounds possible. Where would I source the cable to go from the Mac Mini to the 1612??  I have the Master Link available. Previously I used a Din cable with a pair of RCA’s to get sound to the Overatures AUX port   That may have been the reason for the issues I faced   In hindsight I see how the DIN connector configuration may be an issue in my previous attempt.  

If you also have a RCA to minijack adapter you could try starting combing that with your RCA to din cable. If not try searching for B&O Aux cable minijack and you will probably find the right one

I would like to have the system working in a manner that is easy to use.   I was hoping that the 1612 or another unit would allow me to do so.   Playing through the entire house is my goal.  I will try searching for something with a Mini Jack to connect my Mac Mini to see if I can get an acceptable solution.      I know the Din RCA Jack idea I had was a bit of a bust.

If it turns out its a cable issue you could use either the AUX port on the Ouverture with the phono or n.music command. If you are using BEO4 remotes you will have to find this as a soft button via the LIST button. Using the 1612’s AUX input will hower react to any Video source buttons and therefor be easier accesible.

I was thinking that the best way to do it would be to use the 1612 to make the setup easier to use in the long term.
