4-2. Change the input impedance as needed. The
speaker's input is factory-preset to 1.7 k
Ω . 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 at right.
Step 5. Mount the splash proof cover.
Important
Hook the splash proof cover at every points
marked with arrows in the figure at right. The
splash proof cover is compliant with the
dust/water protection rating IP21C.
Check that the cover is securely fixed to all
hooking positions to protect the speaker unit,
transformer, and connection terminal from water
splash.
(1) Hook the splash proof cover to the cover hook.
(2) Hook the splash proof cover under the Matching
transformer.
(3) Hook the splash proof cover under the terminal
mount.
(X) Do not remove the splash proof cover from these
positions.
Step 6. 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.
