Safety Precautions

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

The PowerMonitors are very ﬂexible in terms of their positioning

and placement requirements. They can be placed on a bookshelf, on or

in an entertainment cabinet (in the open or enclosed behind a grille or

door with appropriate opening to the room), on a stand, or mounted on

the wall. They can be positioned vertically or horizontally (just be sure

that if you position them horizontally that the side of the speaker where

the woofer is located under the grill cloth — you can tell by feeling the

cloth — faces up). The side of the speaker where the woofer is located

should not be pressed right up against a wall or another object but

should have at least 1 to 2" of clearance (the woofer side of the speaker

can be very close to a side wall, just not pressed against it).

Please remember that although these recommendations are usually

valid, all rooms and listening set-ups are somewhat unique, so do not

be afraid to experiment with the speakers. Remember,whatever

sounds best to you is correct.

The speakers should usually be placed a minimum of 5 to 7 feet

apart and kept away from the side walls and corners if possible. A

good rule of thumb is to place the speakers separated by one half the

length of the wall they are positioned along, and each speaker one

quarter the length of the back wall away from the side wall.

Speakers may be angled in toward the listening position or left par-

allel with the rear wall. Angling the speakers in (pointed directly

at the listener) will result in a somewhat brighter, clearer sound with a

sharper focus and a more solid central image (generally,we recom-

mend this), while leaving the speakers parallel with each other will

result in a less bright, more diffuse sound.

Unpacking Your PowerMonitors

Positioning the PowerMonitors in Your Room

Please Inspect For Shipping Damage

Each loudspeaker leaves our plant in perfect condition. Any visible or

concealed damage most likely occurred in handling after it left our plant

and should be reported at once to your Deﬁnitive dealer or the delivery

company that delivered your loudspeaker. Please unpack your system

carefully. Save all cartons and packing materials in case you move or

need to ship your system. Record the serial number found on the back of

the PowerMonitors in the appropriate place on your warranty card.

Your PowerMonitors should sound good right out of the box; howev-

er, an extended break-in period of 20-40 hours or more of normal play-

ing is required to reach full performancecapability. Break-in allows the

suspensions to work in and results in fuller bass, a more open “blossom-

ing” midrange and smoother high frequency reproduction.

The PowerMonitors are mirror imaged (packing cartons are labeled

speaker 1 and speaker 2) with the side mounted subwoofers located so

they may be set up with both woofers facing in (toward each other) or

both woofers facing out (away from each other). (Feel the side of the

speakers to determine which side the woofer is on.) Facing the

woofers in or out will vary the sound somewhat and which way is best

will vary with your room. Again, experiment to determine the best

location for the speakers. If you use a PowerMonitor for a center

speaker, you may use either a speaker #1 or speaker #2, and it may be

positioned either vertically or horizontally.

Speaker Break-In

Hooking Up Your PowerMonitors

Your PowerMonitors each have one pair of gold 5-way binding

posts and one low level RCA LFE input. Normally, you will hook up

the left main/front channel red(+) terminal of your receiver or ampliﬁ-

er to the red(+) terminal of your left PowerMonitor and the left

main/front channel black(-) terminal of your receiver or ampliﬁer to

the black(-) terminal of your left PowerMonitor.Connect the right

channel main/ front channel red(+) terminal of your ampliﬁer or

receiver to the red(+) terminal of your right PowerMonitor and the

black(-) terminal of the right main/front channel of your receiver or

ampliﬁer to the black(-) terminal of your right PowerMonitor. If your

receiver/decoder has a bass management system, tell it that you have

large left and right channel speakers and no subwoofer. The speaker’s

electronics will take an inﬁnitesimally small signal from the speaker

level input and convert it to a low level signal which then drives the

built-in subwoofer power amp.

Connecting Your Loudspeakers

The simplest implementation of use with Dolby Digital is to

simply hook-up your PowerMonitors with speaker wire as described

above and “tell” your bass management system that you have “Large”

left and right front speakers and “no” subwoofer. The bass manage-

ment system will then send the LFE .1 channel signal into the left and

right channels and it will be reproduced by the subwoofers in your

PowerMonitors giving you all the beneﬁts of Dolby Digital and the

discrete LFE signal. Bass management for the center and rear chan-

nels will normally be set on “Small”. (Although this will vary depend-

ing on the speciﬁc speakers; for instance, if you are using a

PowerMonitor,C/L/R 2300, C/L/R 2500, or C/L/R 3000 as a center

channel, you would normally set center on “Large”.) However, you

may wish to experiment with this for best sound in your system.

With Dolby Digital AC-3, you also have the option to use the low

level LFE input in addition to the speaker wires. To do this, simply

use a Y connector coming out of the LFE output jack on your elec-

tronics to feed two line level cables, one connected to the LFE input

on the right speaker and the other one connected to the LFE input on

the left speaker. Tell your bass management system that you have

“Large” left and right main front speakers and “yes” a subwoofer. In

order to properly balance the bass on the front speakers when hooked

up this way,listen to music on the system in stereo and set the level

controls on the back of your speakers for best balance. Then, while

listening to a movie, using the level adjustment for the subwoofer

output on your receiver or decoder, set the LFE output for best sound

with movies. Using this type of hookup will enable you to balance

the bass level control on the speaker for music while boosting up the

LFE level for extra impact on movies. Again, bass management for

the center and rear channels should normally be set as described

above; however, you may wish to experiment for best sound with

your system.

Using Your PowerMonitors with

Dolby Digital AC-3 Systems

Hooking Up with Speaker Wire Only

Using the LFE Input on Your PowerMonitors

Using Your PowerMonitors with an Additional

Subwoofer on the LFE Channel

Your Deﬁnitive PowerMonitors are designed with built-in powered

subwoofers which deliver excellent low frequency response and allow

you to utilize the LFE .1 discrete low frequency bass channel included in

Dolby Digital AC-3. Many listeners (especially those with larger rooms)

may however want to use another additional powered subwoofer for the

.1 channel in order to achieve even more bass impact with many action

movies as well as some other extremely dynamic surround program

material. This can easily be done by hooking the subwoofer to the LFE

output on your receiver or decoder and telling your bass management

system that you have “Large” left and right front main speakers and

“yes” a subwoofer. If you do add another subwoofer, we strongly suggest

adding a Deﬁnitive Powerﬁeld, ProSub, or SuperCube™ in order to

assure a proper match and best sound.

Use of PowerMonitors as Rear or Side Surround Speakers

PowerMonitors make excellent rear or side surround speakers for

the most highly advanced and sophisticated home theater installations.

Because of their built-in powered subwoofers, they allow you to take

full advantage of the full range rear or side surround signal provided

by Dolby Digital, DTS, Dolby EX, 6.1 or 7.1 systems. In order to use

the PowerMonitors as rear or side surround speakers, simply hook

them up as normal to the rear or side channel ampliﬁer outputs of your

system, and set the bass management system of your decoder to

“Large” rear or side surrounds.

Powering Up the Active Subwoofer Section

Your PowerMonitors contain a built-in, active powered subwoofer

section as well as an electronic crossover and so each PowerMonitor must

be plugged into an electrical socket (use an unswitched outlet if possible)

of the appropriate voltage (as indicated on the back of your unit) using the

plug on the end of the black cord attached to the electronics module on the

back of the loudspeaker. The PowerMonitor has a special circuit which

automatically turns the powered subwoofer section on when a signal is fed

to the loudspeaker and does not require an on-offswitch. Please note that if

you here a pop from the speaker when the amp powers up, this is normal.

The red LED on the back panel will light up when a signal is sensed and

the ampliﬁer turns on. Please note that after the cessation of a signal, it

may take up to an hour for the ampliﬁer to actually turn off.

Setting Your PowerMonitors’ Low Frequency Control

Your PowerMonitors have a level control for the electronic crossover

which allows you to perfectly tune the output level of the powered low

frequency subwoofer section to match your room as well as to fulﬁll

your own personal listening preferences. Please note that there are no

controls to vary the crossover points or phase because these have been

factory set to provide perfect blending (a major performance beneﬁt of

this innovative product.). Set the level control so that the sound is most

pleasing to you. Wesuggest starting at about 1 o’clock on the dial.

Normally the level control of the left speaker will be set the same as the

level control of the right speaker. However, these controls can also be set dif-

ferently on the two speakers in order to allow you to vary the response of left

and right speakers separately to compensate for variations and asymmetrical

positioning of the left and right speakers in your room (i.e., when one is clos-

er to a side wall or corner, etc.) if this is how you must set them up. This is a

very unique and useful feature which allows you much greater ﬂexibility in

loudspeaker placement, as well as the ability to optimize what could other-

wise be difﬁcult placement situations.

Setting Low-Frequency Balance When Using Separate LFE Input

We suggest that when you are using a separate LFE input, you set

the bass level on your PowerMonitors to “sound balanced” when lis-

tening to music in stereo and use the .1 channel or bass level control

in your Dolby Digital channel balancing procedure on your decoder to

raise or lower the bass level for movie sound effects.

VERY IMPORTANT: SETTING CHANNEL BALANCE AND BASS MANAGEMENT SYSTEMS

Dolby Digital and Dolby ProLogic systems and decoders have a critical channel balancing

procedure for the left and right front speakers, center channel, rears and subwoofer (if it is hooked up

through the LFE or Sub Out low level connection) which must be followed if the system is to

perform properly. We have spoken with many system users with problems relating to the overall sound

of their system which could be clearly traced back to improper system balance.

Also note that Dolby Digital decoders have bass management systems (systems which direct the bass

to the various channels) which vary from unit to unit. This bass management system must also be

properly adjusted. If your PowerMonitor is hooked up with speaker level wires and no low level LFE

channel input, your receiver or decoder’s bass management system should be set for large left and

right main speakers and NO subwoofer (even though you have subwoofers). This will properly channel

the sub bass LFE information into the left and right channels and then into your

subwoofers. If you have a PowerMonitor, C/L/R 2300, C/L/R 2500, or C/L/R 3000 center channel, you

will usually set your decoder’s bass management center channel setting to “Large” (however, don’t be

afraid to experiment). If not, set it to “Small.” If you are using rear surround speakers with very

extended low frequency response—such as another pair of PowerMonitors—set the rear channels of

your decoder’s bass management system to “Large.” If not, set them to “Small.”

The PowerMonitor Home Theater System

Acomplete PowerMonitor Home Theater System combines a pair

of PowerMonitors with a perfectly matched Deﬁnitive center channel

speaker (ideally,one with a built-in powered sub, such as a C/L/R

2300, C/L/R 2500, C/L/R 3000 or a PowerMonitor), perfectly matched

Deﬁnitive rear and/or side surround speakers, and in many cases a sep-

arate subwoofer for the LFE channel. This superb system offers the

ultimate in-home theater performance with all decoding technologies.

Since the PowerMonitors already have powerful subwoofers built in,

no additional subwoofers are needed, although certainly an additional

LFE channel subwoofer will add even more bass impact, especially in

larger rooms. Remember,to achieve proper blending and full perfor-

mance, it is essential to use only Deﬁnitive speakers to complete your

home theater system.

Setting Bass and Treble Controls on Your

Receiver or Ampliﬁer

Normally we recommend that you set the Bass and Treble controls

on ﬂat or 0 dB. This will give you the most linear and natural sound. If

you want more bass, raise the subwoofer’s Level control on your

PowerMonitor, keeping in mind that even a little turn of the knob can

make a big difference in the sound. Also, if your ampliﬁer or receiver

has a graphic equalizer, we recommend that you leave it ﬂat. The rea-

son for this is that we have spoken with many consumers about what

they thought were improperly sounding speakers when in fact the prob-

lem was misadjusted tone controls. When in doubt, leave them ﬂat;

this almost always sounds the best.

Troubleshooting

If you experience any difﬁculties with your loudspeakers, try the

suggestions described below. If you are still having problems, please

consult your Deﬁnitive Technology Authorized Dealer for assistance.

1. Make sure all your system interconnects and power cords are

solidly in place.

2. Should you experience any level of ground hum or noise, try

plugging the power cord into the same circuit as your ampliﬁer.

3. The system is provided with sophisticated internal protection

circuitry. If for some reason the protection circuitry is tripped,

please turn down your system’svolume and wait ﬁve minutes

before trying the system again. If the ampliﬁer should overheat,

the system will turn off until the ampliﬁer cools down and resets.

4. Check to be sure that your power cord has not been damaged.

5. Check that no foreign objects or liquid has entered the cabinet.

6. If you cannot get the subwoofer driver on the side of the speaker to

turn on or if no sound comes out and you are sure the system is set

up properly,please bring the loudspeaker to your Deﬁnitive

Technology Authorized Dealer for assistance. Call First.
