Speaker Output
The amplifier may be used in conjunction with a speaker rated at 4, 8 and 16 ohms or with balanced 25
volt or 70.7 volt constant voltage speaker systems.
Low Impedance Output(4, 8 and 16 ohm):
The 4, 8 and 16 ohm output terminals are provided for the connection of a few large-output speakers.
This applies when a constant voltage speaker system is unnecessary or in case the distance between the
amplifier and the speakers is less than 200' or 60m.
