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.
Step 1. Confirm that GRIPPLE ® No. 1 (small one) is installed on
a safety wire (thin one) and GRIPLLE ® No. 2 (big one) on
a hanging wire (thick one).
Step 2. Pass the hanging wire over the ceiling anchor point such
as beam or purlin, then pass it through the other hole in
the GRIPPLE ® No. 2.
Step 3. Adjust the length of the hanging wire for the optimum
speaker mounting height.
Step 4. Install the safety wire following the same procedure as
in Steps 2 and 3. Be sure to pass the safety wire over a
different ceiling anchor point from the one the hanging
wire was passed over in Step 2.
GRIPPLE ® No. 1 or No. 2
(accessory, preinstalled)
Safety wire or hanging wire
(accessory, preinstalled)
GRIPPLE ® No. 2
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 first, 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 amplifier’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 amplifier.
• Never set this switch to the "8 Ω" position when
connecting to the amplifier’s high-impedance speaker
line (25 V, 70 V or 100 V), as doing so may damage the
speaker or amplifier.
Be sure to set this switch to the “8 Ω” position when
connecting to the amplifier’s low-impedance line.
CAUTION

The label showing Impedance vs. Input power table is affixed
to the hanging bracket.
"100 V," "70 V," and "25 V" indications in the leftmost column
are "100 V line," "70 V line," "25 V line," respectively.
