4. ABOUT THE INPUT OVERLOAD PROTECTION CIRCUITRY
The speaker system features internal input overload protection circuitry. If an extremely high input level is fed
to the unit, the protection circuitry automatically cuts off the signal to the tweeters.
A drastic reduction in sound volume for the high frequency range indicates that the protection circuitry has
been enabled.
In such cases, simply reduce the amplifier volume. The protection circuitry will automatically reset in
approximately 10 seconds. After reset, try to maintain the volume at a level slightly lower than before.
Caution
This protection circuitry does not completely protect the unit against extremely high input power levels.
Depending on the type or duration of excessive power input, the protection circuitry might not be enabled,
resulting in damage to the speaker element. Also, if the excessive power input continues for a long period of
time, the circuitry may not be capable of resetting to its original condition.
Use the system with care so that the speakers are not exposed to excessive power input.
5. INSTALLATION PRECAUTIONS FOR THE HX-5B-WP AND HX-5W-WP
Only the HX-5B-WP and HX-5W-WP are suitable for outdoor installation.
For outdoor installation, observe the following precautions.
• All speaker modules must point downward from the horizontal. Failure to do so could adversely affect their
intended weather-resistant capability, leading to malfunction.
• Both the HX-5B-WP and the HX-5W-WP employ a splash-proof construction that allows them to be installed
outdoors, but they should only be installed in locations where the ambient temperature is within the range of
–15°C to +50°C. Exceeding the temperature range will cause the speaker to fail.
