Using universal remote control with Line Magnetic amp

I can't say about your specific amp. However, if it was capable of using a remote originally then go to the Logitech Harmony web site and check their database for components it will control.

I have one of their remotes for my AR LS-16 pre-amp and it works but only on a limited number of functions. It will not change input sources.

Thank you, n80.
Will check with Logitech. Problem is I managed to misplace the LM-remote, can't find it at all, so have to look at alternatives

Seems like I require a USC code. I don't know if this code is totally unique to each device, but if not, will someone be willing to share theirs? Please...
I have the LM 518ia

Some remotes have a learning function, point at each other and it will pick up what is needed
