OWNER’S GUIDE

E10, E20, EC25

NORTHRIDGE™E SERIES

SPEAKER PLACEMENT

Proper placement of the speak-

ers is an important step in

obtaining the most realistic

soundstage possible. These

recommendations are for the

optimum placement of the loud-

speakers. Use these placement

recommendations as a guide.

Slight variations will not dimin-

ish your listening pleasure.

All of the Northridge E Series

loudspeakers referred to in this

guide are video-shielded and

can safely be placed near a

television.

CONNECTION TIPS

Speakers and electronics termi-

nals have corresponding posi-

tive (+) and negative (–) termi-

nals. It is important to connect

both speakers identically: posi-

tive (+) on the speaker to posi-

tive (+) on the amplifier and

negative (–) on the speaker to

negative (–) on the amplifier.

Wiring “out of phase” results

in thin sound, weak bass and

a poor stereo image.

With the advent of multichannel

surround sound systems, con-

necting all of the speakers in

your system with the correct

polarity remains as important as

ever in order to preserve the

proper ambience and direction-

ality of the program material.

To use the binding-post speaker

terminals, unscrew the colored

collar until the pass-through

hole in the center post is visible

under the collar. Insert the bare

end of the wire through this

hole; then screw the collar

down until the connection is

tight.

The hole in the center of each

collar is intended for use with

banana-type connectors. To

comply with European CE

certification, these holes are

blocked with plastic inserts at

the point of manufacture.To use

banana-type connectors

requires the removal of the

inserts. Do not remove these

inserts if you are using the

product in an area covered by

the European CE certification.

TROUBLESHOOTING

If there is no sound from any

of the speakers:

• Check that receiver/amplifier

is on and that a source is

playing.

• Review proper operation of

your receiver/amplifier.

If there is no sound coming

from one speaker:

• Check the “Balance” control

on your receiver/amplifier.

• Check all wires and connec-

tions between receiver/ampli-

fier and speakers. Make sure no

wires are touching other wires

or terminals and creating a

short circuit.

• Make sure all wires are con-

nected. Make sure none of the

speaker wires are frayed, cut or

punctured.

• In Dolby* Digital or DTS®

mode, make sure that the

receiver/processor is config-

ured so that the speaker in

question is enabled.

• Turn off all electronics and

switch the speaker in question

with one of the other speakers

that is working correctly. Turn

everything back on, and deter-

mine whether the problem has

followed the speakers, or has

remained in the same channel.

If the problem is in the same

channel, the source of the prob-

lem is most likely with your

receiver or amplifier, and you

should consult the owner’s

manual for that product for fur-

ther information. If the problem

has followed the speaker, con-

sult your dealer for further

assistance or, if that is not pos-

sible, visit www.jbl.com for

further information.

If the sys lays at low vol-

umes but shuts off as vol-

ume is increased:

• Check all wires and connec-

tions between receiver/ampli-

fier and speakers.

• Make sure all wires are con-

nected. Make sure none of the

speaker wires are frayed, cut or

punctured.

• If more than one pair of main

speakers is being used, check

the minimum impedance

requirements of your receiver/

amplifier.

If there is no (or low) bass

output:

• Make sure the polarities

(+ and –) of the left and right

“Speaker Inputs” are con-

nected properly.

• Consider adding a powered

subwoofer to your system for

use with digital “.1” surround

formats.

If there is no sound from

the surround speakers:

• Check all wires and con-

nections between receiver/

amplifier and speakers. Make

sure all wires are connected.

Make sure none of the speaker

wires are frayed, cut or punc-

tured.

• Review proper operation of

your receiver/amplifier and its

surround sound features.

• Make sure the movie or TV

show you are watching is

recorded in a surround sound

mode. If it is not, check to see

whether your receiver/amplifier

has other surround modes you

may use.

• In Dolby Digital or DTS mode,

make sure your receiver/pro-

cessor is configured so that the

surround speakers are enabled.

• Review the operation of your

DVD player and the jacket of

your DVD to make sure that the

DVD features the desired Dolby

Digital or DTS mode, and that

you have properly selected that

mode using both the DVD

player’s menu and the DVD

disc’s menu.

NOTICE:

Important Safety Notes

• Proper selection of mounting

hardware and installation of the

wall brackets are the responsi-

bility of the customer.

• This product is not intended

for ceiling mounting.

Two Number 8 round head or

pan head screws should be

used per loudspeaker. The

screw head should be between

5/16 inch (8mm) and 1/4 inch

(6.3mm) in diameter, and the

screw should be at least 2

inches (50mm) in length.

When installing screws in any

wall, always use properly

selected wall anchors. Attach

two of the four self-adhesive

rubber pads that came with the

E10 loudspeaker to the back of

the enclosure in the two bottom

corners so that the cabinet is

spaced evenly from the wall.

Select a suitable mounting loca-

tion on a wall. (The ceiling is not

a suitable mounting location.)

Drill two pilot holes, appropri-

ately sized for the specific self-

tapping screw or wall anchor

that you will be using. The holes

should be 8 inches (203mm)

apart. See Figure 1. The holes

should be 3/4" (19mm) below

where you want the top of the

enclosure to be positioned. Use

a carpenter’s level to ensure

that the holes are even and that

the speaker will mount on the

level.

Install the two screws into

either a wooden wall stud or

anchor, and tighten them until

the back of each screw head is

about 1/8 inch (3mm) from the

wall. See Figure 2. Install the

loudspeaker by slowly moving

the cabinet toward the screws

so that the screw heads clear

the larger circular portion of the

two keyholes. Once both screw

heads have entered the key-

holes, the loudspeaker should

gently be lowered onto the

screw shafts. Check that the

loudspeaker is firmly locked

onto the screws by gently

pulling the speaker down and

forward.
