4-2. Change the input impedance as needed.
The speaker's input is factory-preset to 1.7 kΩ.
When changing the input impedance, detach the
black wire connected to the matching transformer,
and reinsert it into the desired input tap referring to
the table below.
Step 5. Hook another speaker spring in another catcher.
Then, press the speaker assembly into the
mounting bracket. Force of the springs will keep
the speaker in place.
5. INSTALLATION
Step 1. Make a 150 ±3 mm (5.91 ±0.12 in) diameter hole in
the ceiling. Marking-off pins provided on the
mounting bracket will help draw the circle of its
diameter on the ceiling.
Step 2. Place the mounting bracket in the hole and secure
it with the thumb screws in the two ceiling clamps.
Note
A suspension bolt may be used instead for fixing
the mounting bracket.
Step 3. Hook one speaker spring (V-shaped spring) in the
spring catcher of the bracket.
Step 4. Make wiring.
4-1. Insert the lead-in cables (cables from the amplifier)
and lead-out cables (cables to other speakers) into
the input connector.
