MT 7308 is suitable to control up to 8 additional power amplifiers and relevant speaker lines, according to EN 54-16 norm. It works connected to the MU 7100EN master system unit. When speaker lines drive high power loads, it could be convenient to optimize the system configuration by using one or more dedicated power amplifiers dimensioned according the loads involved. MT 7308 represents a total or partial alternative to the LT 7208EN transformer interface, so that one MU 7100EN can drive at the same time some speaker lines connected directly to an LT 7208EN and some others linked to an MT 7308EN and relevant power amplifiers.
