6. INSTALLATION
Step 1. Secure the ceiling bracket to the ceiling
with 4 screws.
Pull both the lead-in and lead-out cables
through the cable hole in the bracket.

Lead-in and lead-out cables
Tapping screw 4 x 16 (accessory)
Note
If these screws are not appropriate
for the ceiling material, separately
prepare the proper screws.
The input power (impedance) is factory-preset to 6 W
(1.7 kΩ) for 100 V line and 3 W (1.7 kΩ) for 70 V line.
When changing this setting, use a standard screwdriver
to rotate the rotary switch on the upper side of the
speaker to the desired position
The input power (impedance) is factory-preset to 30 W
(330 Ω) for 100 V line.
When changing this setting, use a standard screwdriver
to rotate the rotary switches on the upper side of the
speaker to the desired position.
(1) When operating at high impedance (100 V and 70 V lines);
Set the rotary switch of "LINE VOL." to "100 V" or "70 V" and that of "INPUT" to the input power to be used.
(2) When operating at low impedance;
Set both rotary switches of "LINE VOL" and "INPUT" to 8 Ω.
Important
Be sure to follow the instructions below. Failure to do so may cause damage to the speaker.
• Switch off the amplifier's power when changing the input power.
• Never make 8 Ω connection in a 100 V or 70 V line system, as excessive input power is applied to the speaker,
possibly resulting in damage. (PE-304 only)
5. INPUT POWER (IMPEDANCE) CHANGE
Note
Shown above is an example when the input power is
set to 3 W on 100 V line and 1.5 W on 70 V line.
Note
Shown above is an example when the input power is
set to 20 W on 100 V line.
