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

the shipping company which deliv-

ered your loudspeaker. .

Connecting

Your

Loudspeakers

It is critical for proper performance that both speakers (left and right) be connect-

ed in proper phase. Note that one terminal on each speaker (the +) is colored red and

the other (the -)

colored black. Please make certain that you connect the red (+)

terminal on each speaker to the red (+) terminal

its channel on your amplifier or

receiver, and the black (-) terminal to the black (-) terminal. It is essential that both

speakers be connected in the same way to the amplifier (in phase).

Mythos

Gem

Very

Versatile

Speaker

The Mythos Gem is atremendously versatile speaker which makes aperfect left

and right channel front satellite speaker (when used with aDefinitive subwoofer)

as well as asuperb rear or side surround speaker. We will describe the various

aspects

its use for both

these applications starting with the simplest instructions

first: for its use as arear or side surround.

Positioning

the

Mythos

Gem

as a

Rear

Side

Surround

Speaker

For Rear

Side

Surround

Speakers

The Mythos Gem is designed to be extremely flexible in terms

their place-

ment when used as surround speakers. They may be used on the side walls, rear

walls or in the rear comers

the listening room. When placed along the side walls

the speakers should normally be located adjacent to or behind the listening position.

The speakers may also be placed near the rear comers

the room or located on the

rear wall.

you have your couch or listening position near or against the rear wall,

we suggest rear wall placement

the Mythos Gem with them positioned on either

side

the couch and in from the side wall. High placement is preferred; however,

midwall or floor placement is certainly acceptable. Normally speakers would be

hung on the wall with the input connection plate up against the wall, however, the

Mythos Gem may also be placed on shelves or stands.

course, experimentation is

encouraged to get the best performance in your particular room. As astarting point,

we suggest mounting the speakers on the side walls behind the listening position

about 3-6 feet

off

the floor and halfway between the listening position and the rear

wall.

When using Mythos gem in Dolby EX and other

6.1

and

7.1

systems (which they

are perfect for), one pair will normally be located on the side walls as described

above and an additional 1

2speakers will be located on the rear wall as described

above. IMPORTANT, PLEASE READ: When the Mythos Gem is used as arear

or side surround speaker, the bass management

your receiver or decoder for those

channels:;hould be set to "Small."

Using

the

Mythos

Gems

Conjunction

with

Definitive

Sub

When apair

Mythos Gems is used in conjunction with aDefinitive sub, they

may be connected either directly to the left and right channel

your amplifier

receiver, or to the left and right speaker level outputs

aDefinitive sub (when the

Definitive sub is connected via the high-level speaker wire inputs to the left and

right channel speaker outputs on your receiver). Connecting the Mythos Gems to a

Definitive Sub (which includes abuilt-in high-pass crossover for the Mythos Gems)

will result in greater dynamic range (the system can be played louder without over-

driving the satellites) and is recommended for most installations, especially when

the system is being used for home theater. Because this is the most common set-up,

the following instructions relate to wiring the Mythos Gems to aDefinitive sub.

Wiring 2Mythos Gems

and

1Definitive Sub for Stereo (2-Channel) Use

1) First, wire the red (+) terminal

the left channel speaker wire output

your

receiver or amplifier to the red (+) terminal

the left channel speaker wire (high

level) input

your Definitive Sub.

2) Next, wire the black (-) terminal

the left channel speaker wire output

your

receiver or amplifier to the black (-) terminal

the left channel speaker wire (high

level) input

the Definitive sub.

3) Repeat Steps 1and 2for the right channel.

4) Wire the red (+) terminal

the left Mythos Gem to the left channel red (+)

speaker wire (high level) on the back

the Definitive sub.

Wire the black (-) terminal

the left Mythos Gem to the left channel black (-)

speaker wire (high level)

the back

the Definitive sub.

6) Repeat steps 4&5for the right Mythos Gem.

7) Set the low frequency filter control on the back

the Definitive sub

approximately

clock. Please note that the exact frequency will depend on many factors including

specific positions

the speakers in the room, so you might experiment with aslightly

higher or lower setting to achieve ideal blending between the sub and the satellites for

your particular set-up. Listen to awide variety

music to determine the correct setting

for this in your system.

8) Set the subwoofer level control so that it sounds properly balanced with the satellites.

Please note that the exact level depends on many factors including your room size, posi-

tion

the speakers, etc. as well as your personal listening taste, so you might experi-

ment with the subwoofer level while listening

awide variety

music until you

achieve the ideal setting for your system.

your receiver allows you to choose whether or not the main speakers are

receive

afull-range signal, choose full range (or "Large Left and Right Main Speakers").

Home

Theater

There are many different variations

the basic Dolby ProLogic and Dolby

Digital AC-3 fonnats and features, as well as amultiplicity

ways in which the

speakers can be hooked up to these systems. We will discuss the simplest and most

effective hookups and adjustments.

you have aparticular question regarding your

set-up, please call us.

For

Dolby ProLogic Systems

Follow Steps 1-9 provided earlier. The subwoofer will receive its low frequency

signal through the full-range speaker level outputs.

If,

however, your system has a

separate subwoofer RCA low level output which has aremote control level adjust-

ment, you might also want to hook this up using an RCA-to-RCA low level cable

to the LFE/subwoofer-in low level input (the lower RCA input) on aDefinitive sub.

Then use your remote control sub level adjustment to fine-tune the low frequency

level for different types

program material. You might find you want ahigher level

for some music or for movies.

For

Dolby Digital AC-3 5.1 Systems

Please note that Dolby Digital decoders have bass management systems (systems

which direct the bass to the various channels) which vary from unit to unit.

absolutely critical that the bass management system be properly set in order to

achieve proper perfonnance.

The simplest way to hook up and use your system with Dolby Digital decoders

to hook up the left and right front Mythos Gems and Definitive sub

described

Steps 1through 9earlier. Wire your center channel to the center channel out on your

receiver (or center channel amplifier) and your left and right rear surround speakers

to the rear channel outputs on your receiver or rear channel amplifier (taking care that

all speakers are in phase, i.e. red (+) to red (+) and black (-) to black (-). Set the bass

management system

your receiver or decoder for "Large" left and right main speak-

ers, "Small" center, "Small" rear surround speakers and

"No"

subwoofer. All the

bass infonnation including the

channel LFE signal will be directed to the main left

and right channels and into the subwoofer giving you all the benefits

Dolby Digital

AC-35.1.

Optional Hook-Up

option on this hook-up (if your decoder will allow you to select "Large" left and

right main speakers and "Yes" subwoofer),

addition to the hook-up as described

above,

to use an RCA- to-RCA low level cable to connect the LFE/sub-out on your

receiver to the low-level LFE/sub-in (the lower RCA input) on aDefinitive sub. Tell

your bass management system that you have "Large" left and right main speakers,

"Yes" subwoofer and "Small" center and "Small" surrounds. You will then be able to

raise the LFE

channel level being fed to the subwoofer by either using the LFE/sub

remote level adjustment on your decoder (if

has one) or the LFE

channel level con-

trol on your Dolby Digital channel balancing procedure. This set-up has the advantage

allowing you to set the low frequency level on the Definitive sub for smooth

balance with music while also allowing you to "juice up the bass" for movies with

the controls on your decoder.

should also sound somewhat better.

Variation on

the

Optional

Hook-up

One variation on the optional hook-up

hook

and adjust the system

described under "Optional Hook-Up" except select "Small Left and Right Main

Speakers" and a"Subwoofer" on the bass management system (along with "Small

Center" and "Small Rear Surrounds"). The advantage

this over the Optional Hook-

Up will

somewhat greater dynamic range (i.e., you can play the system louder).

However, depending on the specific characteristics

the crossovers designed into your

bass management system, the transition and blending between the satellites and sub-

woofer may not be quite as smooth and continuous as the Optional Hook-Up, or with

the basic hook-up detailed above

Steps 1-9. However, ifyou wish to play the system

louder, you can experiment with this variation.

addition, this variation is also one

which

can

used

your

decoder

management

system does

not

allow a

"Large

and

Right

Main

Speakers"

and

"Subwoofer" setting.

We encourage you to experiment with the various settings on your subwoofer,

settings on your decoder, and hook-up options

described until you find the best

combination for you.

Using

Mythos

Gems

with

Definitive

Sub

for

Rear

Channel

Surround Use

Since Dolby Digital is capable

delivering afull-range bass signal to the rear

channels, some more elaborate systems will include an additional Definitive sub for

the rear channels. In this case, simply wire the Mythos Gems to the Definitive sub

as described in 1thru 8earlier, except wire to the rear surround outputs. Set the

bass management system for "Large Rear Speakers."

Speaker Break-In

Your Mythos Gems should sound good right out

the box; however, an

extended break-in period

20-40 hours or more

playing is required to reach

full performance capability. Break-in allows the suspensions to work in and

results in fuller bass, amore open "blossoming" midrange and smoother high

frequency reproduction.

Positioning

Mythos

Gems

when

Used

Front

Main

Speakers in

Your

Room

It is important that some simple set-up recommendations be followed in order to

assure optimum performance in your room. 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 Mythos Gem Loudspeakers may be placed on astand or shelfor be mounted

on the wall. Placement close to the wall will increase the bass output while

placement further from the rear wall will decrease the bass output.

When used as fronts, the speakers should usually be placed 6to 8feet apart

and kept away from the side walls and comers. Agood rule

thumb is to place

the speakers separated by one half the length

the wall they are positioned along,

and each speaker one quarter the length

the wall behind them away from the

side wall.

Mounting

Your

Mythos

Gem

with

the

Supplied

Wall-Mount

Template

Your Mythos Gem comes with an optional wall-bracket designed to securely

mount your speaker flush to your wall. The bracket can

ONL

Ybe used with a

vertical installation. For safety, it is extremely important that this bracket be installed

with molly-bolts or similarly effective fasteners appropriate for the construction

your wall. Be sure to use all four

the mounting holes when fastening the bracket

to the wall. Never use unanchored

improperly anchored screws in your wall.

Professional installation is strongly recommended. Your dealer can either arrange

this for you, or refer you to aqualified installer.

To determine the bracket's position on the wall, use the mounting template which

comes with your speakers.

you are mounting your Mythos Gem close to anything

above it, please allow an extra 11/4 inches above the top

the speaker for the

speaker to slide onto its bracket.

your speaker wires are to be hidden inside the wall, be sure to conform to your

local building codes. When installed on the bracket, the center

the Mythos Gem

speaker terminals will be as indicated on the template.

To install the Mythos Gem on'its bracket, securely fasten the mounting screw

supplied into the threaded hole on the rear

the speaker, screwing it in as far as it

will go. The speaker will then hang in the "keyhole" on the bracket. After placing the

screw in this opening, pressing down firmly on the top

the speaker will seat

the speaker properly and avoid any rattles during use.

addition, the Mythos Gem has athreaded insert on the back which may be

used with awall-mount pivoting bracket such as the Definitive ProMount 80.
