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.

Note
If these screws are not appropriate
for the ceiling material, separately
prepare the proper screws.
If these screws are not appropriate

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
(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.
(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,
• 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)
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.
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.
Shown above is an example when the input power is
set to 20 W on 100 V line.
