70-Volt/100 Watt Line (320-1032) Features Faxback Doc. # 16224 Transformer The 70-Volt/100 Watt Line Transformer has been designed to convert the 40 ohm speaker output of a PA amplifier, such as our MPA-90, for use with 70-volt line transformer speaker connections. This type of system minimizes power loss when speakers are located long distances from the amplifier and simplifies the connection of multiple speakers (more than 4 speakers), especially if all speakers do not have the same impedance.
