3-2. Change the input impedance as needed.
The speaker's input is factory-preset to 1.7 kΩ (PC-
1869, PC-2369 and PC-2869) or 670 Ω (PC-2852).
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
tables below.
Never connect to the 330 Ω tap in a 100V line system,
as excessive input power is applied to the speaker,
possibly resulting in damage.
Step 4. Push the panel surface into the mounting hole.
4. INSTALLATION
Step 1. Using the supplied paper pattern as a guide, open a
mounting hole of the dimension specified below in the
ceiling.
Step 2. Hook the speaker mounting spring into the mounting
hole in the ceiling.
Step 3. Make wiring.
3-1. Insert the lead-in cables (cables from the amplifier) and
lead-out cables (cables to other speakers) into the
input connector.
