5. OVERLOAD PROTECTION CIRCUITRY INFORMATION
(LOW-IMPEDANCE MODELS ONLY)
4
The F-160G, F-160W, F-240G, and F-240W have a built-in overload protection circuitry.
If the excessive input is applied to a woofer or tweeter, the overload protection circuitry is activated and cuts
off the signal supply to the speaker component.
A sudden drop of the volume level of either the high or low frequencies during speaker operation indicates
that the overload protection circuitry has been activated. In such a case, reduce the amplifier volume and just
wait. The protection circuitry is automatically reset after approximately 3-30 seconds. After the circuitry is
reset, set the volume at a lower level than before.
[Important Note]
This overload protection circuitry does not perfectly protect the speaker component. Depending upon the
excessive input to be applied, the protection circuitry may not operate, causing damage to the speaker
component. In addition, the circuitry may not be restored to the previous state if the excessive input is applied
continuously for long time. Take special care that the excessive input is not applied to the speaker during use.
Two-way bass-reflex system.
High efficiency, wide range, and high input power handling capacity.
F-160 series: High power capacity 13 cm woofer with a large 90 mm magnetic circuit, and high-efficiency
3 cm dome tweeter with a large 70 mm magnetic circuit.
F-240 series: High power capacity 16 cm woofer with a large 90 mm magnetic circuit, and high efficiency
3 cm dome tweeter with a large 70 mm magnetic circuit and a titanium diaphragm.
The tweeter employs a constant directivity horn which ensures uniform sound dispersion of 90 ° horizontal
and 90° vertical.
Independent built-in overload protection circuitry for woofer and tweeter. (Low-impedance models only)
A detachable rear cover cleanly conceals the speaker terminals.
Acoustically efficient polypropylene enclosure.
Optional wall and ceiling mounting brackets.
F-160WP: Drip-proof construction makes the speaker system ideal for outdoor use.
Use optional mounting brackets when mounting the speaker to the ceiling or wall.
Avoid using the speaker on the beach because the speaker's life can be greatly shortened by sea breezes.
TOA takes no responsibility for any accident or equipment failure due to inadequate installation places or
incorrect installation methods or disassembly or modifications carried out for the purposes other than repair
service.
The F series speaker is not magnetically shielded. Install it as far away as possible from color televisions or
video monitors to avoid degradation in television picture quality.
