I have a couple of splitters which I could use.

In the past I tried to use them to share an aux socket for dual input (record deck and apple express) into the beosound 9000.  I found that when both inputs were connected the sound level was much reduced and very flat/dull.

I assumed this was something to do with impendence to the signal input.

Might this be a problem in the scenario of using a din cable with i/o switched?

This is completely correct. Never use a splitter, which means splitting one output to two inputs, as a mixer (or merger) which means, mixing two outs to one input. outputs are low impedance and inputs are high impedance..but read yourself - here is an article that also offers a solution..

Given that you have masterlink cables in place, wouldn’t a 1611 converter be a better solution?

This was the original plan many years ago - however we subsequently found out that you can't have 2 audio masters in the same system.

Hopefully I'm not mistaken on this.

Quite right - one would have to be Audio master and the other audio slave. On the slave you’d access all sources as normal on the remote, but can also access sources from the master by pressing LINK then the relevant source. The master cannot access the sources of the slave device so you’d need to pick which way you want carefully. The 1611 converter with the most recent software can act as master or slave so you’d have some flexibility.

Unfortunately I dont think either the beocenter 9500 or the beosound 9000 (possibly series 1) can be a slave unit.
