I found that when both inputs were connected the sound level was much reduced and very flat/dull.
Yes I have had this problem with two 'live' devices connected to one of the BC9500's aux inputs using the cable that I linked to.

Might this be a problem in the scenario of using a din cable with i/o switched?
This is what I was trying to explain as a solution. Your current input device is probably not using the BC9500's Aux output pins (1 and 4), so if you connect just these to the BS9000 you should not have a problem.
An alternative solution would be to make up a bespoke plug to take an aux output from the Line In/Out 'dummy' plug above the Powerlink 1 socket. You would need to make sure that your connection still connects pins 1 to 3, and 4 to 5.
