Absolutely ditto ... each device has an input and output impedence which is usually very different. It does pay to check it all in your manuals since impedence matching is important (e.g., the output impedence of your preamp should be a good bit -- e.g., 10 times -- lower than the input impedence of your power amp). What you describe is typical so you should have no worries.
