I have a KMA-20 audio panel and PS engineering intercom installed. When everything on the audio panel is turned off, it leaks whatever is tuned into com #2 through the cabin speaker. It plays at about 30% of the volume as if I actually turn com #2 on to the cabin speaker. Through my headsets and intercom everything seems to work fine. I typically leave the ATIS on com#2 so it's always playing in the cabin and is distracting. Any ideas what would cause com #2 to always be on to the cabin speaker? Thanks in advance.
