You can find user manuals and support documents on the McIntosh website by viewing Product Support Downloads and choosing CD Players under Product Category then MCD1100 in the Model Number field if you don't already have the documentation that came with your player.

My experience with McIntosh documentation is that it is very comprehensively written and covers all aspects of a product's operations.

I would suggest any connection other than optical, which limits resolution.

Try a good quality coaxial cable and you will forget about the optical connect.
