I looked at the admin manual but it didnt say much.. So how do I find out what unit was assigned to the embedded ASU? If I was using the embedded ASU id need to set it to "embedded" wouldnt I??

The 3300 in question is using an external digital music source, that needs plugging into the phono port which suggests to me I need to set it to "external", thus needing the 4 digits for port/loc ID.

Thanks..
