6. Setting transformer taps
1. The rotary transformer tapping switch is located directly above the wiring connector.
CAUTION: The loudspeaker is supplied with the tap switch set in low impedance mode. Never connect the
loudspeaker to a 70/100 V amplifier output while switched to low impedance mode.
2. Set the rotary switch to the appropriate position for low impedance operation or for use in 70/100 V
distributed systems.
Models with 5-inch drivers are fitted with 30 W transformers. In distributed line applications, the transformer can
be tapped at 30 W, 15 W and 7.5 W, with an additional 3.75 W tap for 70 V line systems.
Models with 6-inch and 8-inch drivers are fitted with 60W transformers. In distributed line applications, the
transformer can be tapped at 60 W, 30 W and 15 W, with an additional 7.5 W tap for 70 V line systems.
