Baffle Wiring And Installation - JBL Synthesis SCL-2 Owner's Manual

BAFFLE WIRING AND INSTALLATION

CONNECTING THE BAFFLE TO THE BACK BOX
The SCL-2 requires hook up of wires from the baffle to the back box enclosure. The bundle of wires connected to the
baffle is pre-terminated with a Molex plug that plugs into the corresponding Molex socket inside the back box. Once
the back box has been installed and the baffle is ready for installation, snap the Molex plug into the socket (Figure 18).
NOTE: The baffle in this figure is oriented purely to show the Molex connection on the baffle wires and the crossover
in the backbox. Correct orientation is actually with the horn toward the crossover end of the backbox (Therefore, the
baffle in the illustration above would actually be rotated 180 degrees from what you see in the image above in order to
align properly with the back box).
WARNING:
DO NOT OVER-TIGHTEN BAFFLE MOUNTING SCREWS! If using power tools to secure the baffle screws, use
the lowest torque setting - enough to pull the baffle to the wall where the gasket just touches the mounting surface.
For proper sealing of gasket and vibration isolation, hand tighten screws the rest of the way to approximately 8 to 16
in-lbs maximum. (This is equivalent to approximately 1/2 - screw head rotation from when baffle gasket just touches
enclosure and wall surface).
1. Connect the speaker baffle signal wire bundle Molex plug to the Molex
socket in the back box. The connectors are keyed to only allow correct
connection. DO NOT FORCE.
2. Orient the SCL-2 so the horn is close to the terminal cup.
3. Position the baffle assembly into the back box. The baffle gasket should
be seated on the back box edge. CAUTION: Make sure to carefully guide
terminal connection wires when inserting the baffle to prevent pinching the
wires during assembly.
4. Attach the baffle to the back box with the ten supplied screws (Figure 19).
Start with tightening the center mounting screws.
5. Secure perimeter baffle mounting screws and tighten (See WARNINGS
concerning over-tightening screws!).
6. Remove JBL Logo adhesive back and insert onto the grille with proper
orientation.
7. Place the zero bezel metal onto baffle. Align the top edge and then
let the grille gently 'drop' onto the baffle as it is pulled in place by the
magnets. Magnets on the baffle will secure grill. Be sure the grille sits
flush with the wall all the way around; a grille sitting up on the baffle
could fall off during operation.
