i did search for this and came up with nothing.

what does the "comp" button on the mach mp3 radio mean and what does it do?

 

that is a really good question. i dont kno. "component" maybe. maybe try pushing it and see wat it does lol.

 

i can't really tell that it does anything. i think it just gets a little bit louder but it may just be me. oh well, screw it lol

 

COMP (Compression): In CD mode, press to bring louder and softer levels into more comfortable listening level.


mmm also in the Manual:
Compression (CD): Press to bring soft and loud passages together for a more consistant listening level.

 

Yep. It is compressor. If you like blasting music on the stock CD player, it will be much better with COMP turned on.

 

and now we kno
