Important - Harman JBL L52 Classic 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 L52 Classic has color-coded connection terminals. The "+"
terminal is red, while the "–" terminal is black. See the illustration on the right.
The L52 Classic is designed so that a positive voltage at the "+" (red) terminal will
cause the speaker drivers to move outward (toward the room).
We recommend using a high-quality speaker cable with polarity coding. The side of the
wire with a ridge or other coding is usually considered positive polarity ("+").
To ensure proper polarity, connect each "+" terminal on the back of the amplifier or
receiver to the respective "+" (red) terminal on each speaker. Connect the "–" (black)
terminals in a similar way. See your receiver or amplifier's owner's manual to confirm its
connection procedures.

Connect the amplifier to each speaker as shown in the
illustration on the right.
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 L52 Classic's gold-plated speaker terminals
can accept a variety of wire connector types: bare
wire, spade connectors, pin connectors and banana
connectors.
USING BARE WIRE OR PIN CONNECTORS:
IMPORTANT: Make sure that the (+) and (–) wires or pins
do not touch each other or the other terminal. Touching
cables can cause a short circuit that can damage your
receiver or amplifier.
USING SPADE CONNECTORS:
IMPORTANT: Make sure the (+) and (–) spade connector blades
do not touch each other or the other terminal. Touching blades
can cause a short circuit that can damage your receiver or
amplifier.
