JBL Synthesis SCL-2 Owner's Manual page 7

BI-WIRE OR BI-AMPLIFIER OPTIONS
The SCL-2 has two sets of connectors to allow for bi-wire or bi-amp operation.
1. Cut two pair of wires for each bi-wired speaker.
2. Mark both ends of the wire pairs intended for low frequency use as "LF," and both ends of the wire intended for
high frequency use as "HF." Then run the two sets of wire to the mounting position.
3. Connect "HF" labeled pair to the speaker's "HF" input, and the "LF" labeled pair to the "LF" input. (Figure 10)
4. Before installing the speaker that will be bi-wired or bi-amplified, remove the two blue jumpers, Bi-amp Jumper
Hot and Bi-amp Jumper Ground (Figure 11). The blue jumpers are located on the terminal cup on the inside of
the back box. Squeeze the connectors for the jumpers just below where the wire is crimped to the connector to
release the connector lock. If this doesn't work, slide the plastic boot back onto the wire and depress the lever
for the lock with a ballpoint pen or small tool while pulling gently on the wire.
5. Proceed to install the back box and speaker following the instructions elsewhere in this manual.
