Anybody using the Gainmaker series amps have a problem with level changes after balanced. This is not an initial balance but re-balance of an existing system. I have noticed in a few different areas that my levels have changed in a few weeks. Nodes in those areas stable, so I know it's not that. Also I set the backoff and agc's properly while balancing.
