5. IMPEDANCE CHANGE
The input impedance is factory-preset to 1.7 kΩ.
To change the impedance, change the rear
panel-mounted rotary switch position to the
desired impedance (wattage) using a standard
screwdriver.
Notes
• This speaker is designed to operate on a 70 V
or 100 V line. Do not connect it to the
amplifier's low impedance line.
• No sound is output when the switch is set to
the OFF position.
Caution
Never set the switch to "–" position for 100 V
line operation, as doing so may result in damage
to the speaker.

with the speaker.
Use commercial mounting
hardware appropriate for the
installation environment.
• Please install only with either
flexible conduit or flexible
wiring.
