The AM1200 Sound Masking System is a highly versatile system for use on small projects. It has two built-in speakers set as a horizontal array and a 12 Watt amplifier that can be used to power remote masking speakers through a 70.7V output. Each of the two types of speakers has a separate level control and the system has a Hi-Cut filter as well as a Pink or White basic noise source. The cabinet is only 2½" high so it fits into a small ceiling plenum or under a shallow raised floor. It has two mounting supports so that it can be suspended in a higher ceiling plenum. It has four mounting holes so that it can be mounted on most surfaces.
