Iwould like to know how to pogramm another one. (logitec Harmony One) ?
No response with
if they list your preamp on their web site then all you have to do is plug the remote into your computer, run the software wizard thing and it will program it, if it is not supported by that remote, you are out of luck. Look at different remotes on the logitec site, different ones support different equipment.
I was not aware that the GTA SEP-1 ever had a remote. But, try the Golden Tube user group in Yahoo.
