Can I inject audio into this old house intercom speaker system?
Found a transformer attached to one of my house intercom speakers and got curious how this system works.
Looks like all room speakers are connected through the same line. Is this a distributed/70V audio system?
Could I safely inject audio/music into the line somehow so it plays through the other speakers in the house?
