[. . . ] [. . . ] Multiple KDA amplifiers may be daisy chained together eliminating the multiple long copper runs associated with 70/100V systems and allowing easy facility expansion with no concern for induced noise or ground loops. KDA amplifiers offer an efficient and effective alternative to creating large area multizone systems in new facilities by eliminating amplifier floor space requirements and ensuring quality operation.
