1. Introduction
Thank you for purchasing the
JBL
®
3-Way Studio Monitor 4319.
For more than 60 years, JBL has been providing audio equipment for concert halls, recording studios and movie theaters
around the world and has become the hands-down choice of leading recording artists and sound engineers. The 4319 is a
new member of the family of JBL bookshelf studio monitor speakers that dates back to 1968 with the original model 4310
Control Monitor. To get the best performance from your new studio monitor, please read these instructions thoroughly.
2. 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.
3. 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 where they will be
exposed to other strong light.
• The 4319 is not video-shielded, and may cause picture discoloration
or distortion if placed close to some types of TVs. If this occurs,
move the speakers away from the TV until the discoloration or
distortion disappears.
• For best results, place the speakers 6–8 feet (1.5m–2.5m) 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.
4. 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 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 (“+”).
