Installation
1. To avoid breakdowns, we suggest that you install the
speaker in the areas where the ambient temperature is
from -15°C to +50°C. In snowy areas, protect unit
from the snow.
2. When installing the speaker, use the optional mounting
bracket for outdoor installation. Also, take care about
the following:
(1)The bottom surface of the speaker has two air
vents and one drain hole. Be sure to mount the
speaker with that side down, taking care that such
holes are not blocked. (The drain hole is for drain-
age of rainwater that enters the horn.)

(2)As shown in the figure below, the speaker can be
positioned at any angle from 0° (horizontal) to a 45°
downward angle. As this mounting range permits
free drainage of rainwater from the inside of the
speaker, do not exceed this range, nor direct the
speaker upward.

1. Polarity
When connecting the speaker, observe the polarity
shown in the figure below.
2. Impedance switching (Only available for F-500WP and F-600WP)
The speaker input impedance can be switched in 4
steps with a built-in selector. See the table below.
The impedance is factory-preset to position 3.

Overload protection device
The speaker is provided with individual overload protec-
tion devices for woofer and tweeter. (When the woofer's
device is activated, the woofer's output signal level is
attenuated by about 15 dB, while the tweeter is cut off if
the tweeter's device is activated.) If the sound volume of
the woofer or tweeter suddenly decreases during use,
this indicates that the protection devices have leaped into
action. In such a case, lower the speaker input power
level once first to wait till the protection devices automati-
cally return to the normal condition (about 2 to 20
seconds). After they are reset, use the speaker turning
down the volume a little more than before.
