Whats this for?


I bought a Mark Levinson 326S here and was looking over the owners manual box contents and I read "1/8-inch hex key". What the heck would an allen key come with a preamp for? While I don’t have the preamp in possession right now to look at screws. Would Madrigal/Harmon want you to remove the bottom of the unit for some reason, what reason? Or is it the feet that you can change?

You might have dip switches inside to set your max gain for the volume control.

I've heard that some equipment makers will "float" the PC board on springs to isolate from external vibration. They are secured for transport with a screw that must be released once received. This is especially true for CD players but can see it on pre-amps, etc. Look for a hole on bottom of unit or read instruction book.
