TYPICAL 6-ROOM INSTALLATION NOTES ABOUT HUM: SPECIFICATIONS: Rated Power Output: Bridged Power Output: While the MA1240a has been designed to minimize the possibility of hum in the audio system, it is still possible that a hum will occur in rare circumstances. Its safety grounding can create a path for small amounts of 60 Hz energy to travel through the line-level audio system.
