Selecting Power Levels
The front-mounted selector switch is used to set the appropriate power level or impedance for your system. Using a small flat-blade screw- driver, turn the knob until the slot points to the power level you require.
70V/100V Systems
Both power setting scales for 70V and 100V sys- tems are labeled on the speakers. On the 100V scale, the last position clockwise is marked with
a (not available) symbol. Do not use this posi- tion in 100V systems.
16Ω Systems
The fully counterclockwise position of the setting switch is the 16-ohm position.This setting is suitable for use with low-impedance amplifiers that typically support 4- or 8-ohm speakers.The speaker’s higher, 16-ohm impedance makes it easier to combine multiple speakers into series - parallel networks while keeping the total system impedance at a level suitable for low-impedance amplifiers.
