1. Introduction

Thank you for purchasing the JBL® 4312EBK 3-Way Studio Monitor.

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 engi-

neers. The 4312EBK 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 4312EBK box contains one (1) JBL 4312EBK studio monitor speaker. If you suspect that there has been ship-

ping damage, report it immediately to your dealer. We recommend that you keep the box and packing materials for

future use.

3. Placement

CAUTION: The 4312EBK weighs 39.5 lb (17.9kg). 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 4312EBK is not video-shielded, and may cause picture discol-•

oration 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 (1.8-2.4m) 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 4312EBK has color-coded connection terminals. The “+”

terminal is red, while the “–” terminal is black. See the illustration on the right.

The 4312EBK 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 “+”

( ) terminal on each speaker. Connect the “–” ( ) terminals in a similar way. See your receiver or ampliﬁer’s red black

owner’s manual to conﬁrm its connection procedures.

5. 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 4312EBK’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 wires

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.
