PaCkagE COnTEnTs
each JBL 4319 box contains one (1) JBL 4319 studio-monitor speaker. if
you suspect that there has been shipping damage, report it immediately to
your dealer. We recommend that you keep the box and packing materials
for future use.
PLaCEMEnT
CAUTION: The 4319 weighs 35.9 lb (16.3kg). Before placing the
speaker on a shelf or platform, be sure that it is sturdy enough to
support the speaker
’
s weight.
Before deciding where to place your speakers, survey your room and think
about placement, using the illustration below as a guide.
• Avoid placing the speakers near power amplifiers, heat registers
or other objects that generate large amounts of heat.
• Do not place the speakers in very humid or dusty places.
• Do not place the speakers in direct sunlight or other strong light.
• The 4319 is not video-shielded and may cause picture discolouration
or distortion if placed close to some types of tVs. if this occurs, move
the speakers away from the tV until the discolouration or distortion
disappears.
• For best results, place the speakers 5 – 8 feet (1.5 – 2.5 metres) apart.
if you place the speakers farther apart than this, angle them toward the
listening position.
• The speakers will produce the most accurate stereo soundstage when
the angle between the listener and the speakers is between 40 and 60
degrees.
• Position each speaker so that its tweeter is approximately at ear level.
• Generally, bass output will increase as the speaker is moved closer to a
wall or corner. For best performance, we recommend that you place the
speakers at least 20 inches (50cm) away from the side walls.

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 4319 has two sets of connection terminals
that are marked “+” and “–” on the terminal assembly. Additionally, the “+”
terminals have red rings, while the “–” terminals have black rings. See the
illustration on the right.
The 4319 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 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 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.
BasiC singLE-WirE COnnECTiOn
Connect the amplifier to each speaker as shown in the illustration on the
right. You can use either set of terminals on the speaker. NOte: do not
remove the metal jumpers 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 4319’s gold-plated speaker terminals can accept a variety of wire
connector types: bare wire, spade connectors, pin connectors
and banana connectors.
