4. INSTALLATION AND CONNECTION
Note
Localcodesmayrequireotherinstallationmethods.Checkwith
authority having jurisdiction to determine acceptability of the
mountingmethodsshownhere.

Followtheinstructionsbelow.
Doing otherwise may cause the speaker fall, resulting in
personalinjury.
• Neverhangthespeakerwiththesafetywire.
• The surplus length of the safety wire must be within
30 cm (11.81") from the state that the safety wire is
tight.
• Install the hanging wire rst, then the safety wire.
(Neverreversethisorder.)
CAUTION
3. INPUT POWER (IMPEDANCE) CHANGE
Turntherotaryswitch(ontherearsideofthespeaker)tosetitto
thedesiredinputimpedanceusingaslottedscrewdriver.
Note: Settherotaryswitchwithoutremovingthehangingbracket.
• Switch off the amplier’s power when changing the
inputpower.
• Neversettherotaryswitchtothe"170Ω"(PE-304BU,
PE-304WU)or"83Ω"(PE-604BU,PE-604WU)position
whenoperatingthespeakeron100Vline.
 Failuretofollowthisinstructioncouldresultindamage
tothespeakeroramplier.
• Never set this switch to the "8 Ω" position when
connectingtotheamplier’shigh-impedancespeaker
line(25V,70Vor100V),asdoingsomaydamagethe
speakeroramplier.
 Besuretosetthisswitchtothe“8Ω”positionwhen
connectingtotheamplier’slow-impedanceline.
