Change input labels


I have a Marantz 2250b and the labels on the input dial are not related to my system at all. For example my phono stage goes to Aux and my DAC goes to Tape 1. My DAC has three inputs (computer, airport, and chromecast) labeled 1, 2, & 3. So no indication of what is what.

I can keep things straight because I set it up by my family gets frustrated.

Are there any methods for re labeling the faceplates of these devices that don’t look like $#! +?

You have vintage quality unit and want to replace labels??
I'd rather use some stickers with notes, but would never touch neither faceplate or rear panel. 

Ideally, I was thinking of small labels that could be removed with no damage alá the ubiquitous label makers - only much, much smaller.

No permanent Alterations. 
I have a Brother P-touch label maker, model PT-D210, that accepts label tape in 1/4, 3/8 and 1/2 inch widths and three font sizes. The tape is available in a wide variety of colors for both the tape and the print. Maybe either white or black print on either black or matte-gray tape would work? Or if you have a Jadis amp, black on gold would be a nice touch. Cutting out the little labels would be a bit fiddly but you’d have to do it only once.

Saar,
Can you adjust the font size regardless of the tape size? 
1/4 inch seems to large but you mentioned cutting text out?
