4.11.1 Before operation
• To get the best performance from this speaker system, first read the instruction manual. Keep the manual handy for
easy future reference.
• The speaker's nominal impedance is 8
Ω
. Connect to a stereo amplifier capable of driving loads ranging from
4 to 16
Ω
.
• Observe the following precautions to protect the speaker from damage caused by high input.
• Do not apply inputs higher than the recommended level.
• Turn off power to the amplifier before inserting or removing the pin-plug.
• Do not turn up audio volume beyond recommended levels, when increasing the high-frequency output with a
graphic equalizer.
• Particularly with relatively low-capacity amplifiers, do not drive close to their rated maximums. (Doing so will
produce square waves that can destroy tweeters. )
• Handle the speaker grilles and cabinet carefully to prevent damage caused by shock.
• To protect the speaker from excessive input and abnormal signals, the system contains an automatic return-type
protective device. When excessive input is applied to the speaker, the protective device activates to kill sound
output. If this occurs, decrease the amplifier volume. The sound should return in 5 to 10 seconds.
