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.
