Connections; Basic Single-Wire Connection - JBL Classic Series Owner's Manual

COnneCTIOns

CAUTION: Make sure that all of the system's electrical components are turned OFF (and preferably
unplugged from their AC outlets) before making any connections.
Speakers and amplifiers have corresponding positive and negative ("+" and "-") connection terminals. The L100 Classic
75 has two sets of connection terminals; gold-plated jumper straps connect the termilnais to each other. The termilnals
are marked "+" and "-." Additionally, the "+" terminals have red rings, while the "-" terminals have black rings. See the
illustration below.
We have designed the L100 Classic 75 so that a positive voltage at the "+" (red) terminal will cause the speaker
transducers to move outward (toward the room).
We recommend using a high-quality speaker wire with polarity coding. The side of the wire with a ridge or other coding
is usually considered positive polarity ("+").
To ensure proper polarity, connect the left- and right-channel '+" terminals on the back of the amplifier or receiver to
their respective "+" (red) terminals on the speakers. Connect the "-" (black) terminals In a similar way. See the owner's
manual of your receiver or amplifier to confirm its connection procedures.

Connect the amplifier to each speaker as shown in the illustration below. You can use either set of terminals on the
speaker. NOTE: Do not remove the jumper straps from between the two sets of terminals when connecting the speaker
wires.
IMPORTANT: Do not reverse polarities (i.e., "+" to "-" or "-" to "+") when making connections. Doing so will cause poor
stereo imaging and diminished bass performance.
The L100 Classic 75's gold-plated speaker terminals can accept a variety of wire-connector types: bare wire, spade
connectors, pin connectors and banana connectors.
