A Message from Genesis

Congratulations! You are now the owner of one of the finest

loudspeaker systems in the world! Based on the technologies

developed for our flagship Genesis 1.1, the G5.2 is a smallish 4-ft tall

floor-standing loudspeaker, and yet it delivers some of the imaging

and soundspace of our largest 7-foot tall products.

The G5.2 loudspeaker system was created for the music lover living

in the metro-environment. It is designed to reproduce music (and

film) at live listening levels with virtually no restrictions on dynamic

range, frequency response, or imaging capabilities. This is what we

mean by absolute fidelity™, the ability to reproduce the musical

event faithfully, as was intended by the performer, or the film-maker.

Standing 44 inches tall, and only 11 inches wide, the Genesis 5.2 is

a diminutive giant. By means of an active servo bass, response

down to 20Hz is achieved, and the full range and impact of a

symphony orchestra or a rock band can be reproduced.

Please read this Owners Manual and Set-up Guide to get the

maximum enjoyment out of your purchase. Also, if you have access

to the internet, please check back at our website often. The address

is www.genesisloudspeakers.com. We will put the latest updates,

tips and tricks, and support for our owners on our website.

Please write the serial number and purchase details of your

Genesis 5.2 here for future reference.

A Quick Start Set-up Guide

Now that you have your new Genesis 5.2 loudspeaker system, we

realize that you can’t wait to hook it up and start playing! However,

please read this quick set up guide (even if your dealer is setting it

up for you!) before you proceed.

Unpacking

Your loudspeakers will come to you in two large shipping cartons.

The G5.2s weigh over 140lbs (63.5kgs) each, so we suggest a

minimum of two strong people to move the speakers around. We will

not be held liable for damage (to either the speakers or your backs!)

during unpacking and setting up.

Room Placement

A good starting position for your G5.2 is about 20% the way into the

room as measured from the front wall (the wall you look at as you

are seated listening to the speakers), six feet apart, and firing

straight ahead with no toe-in. You will want to sit ten to twelve feet

away from the speakers.

Set-up Guide

Positioning

A good starting position for the G5.2 is about 20% of the way into

the room as measured from the front wall (the wall you look at as

you are seated listening to the speakers). Start with the speakers six

feet apart, and not toed-in. You will want to sit 10 to 12 feet away

from the speakers (if you have the space). We will experiment with

moving the speakers around, and toeing them in later.

Power Connections

There are two connections you will

need to make to the G5.2. First, the

power cord for the built-in amplifier

will need to be plugged into a power

socket. A 10-foot power cord is

included with your speakers for this

purpose. We do not recommend

using an extension cord for the G5.2

due to the high power demands of

the 500W amplifier. However, if you

MUST use an extension cord, use an

extremely heavy duty one.

Before you plug the power cord in,

please make sure that the voltage

selector is set to the proper voltage.

Taiwan, Japan and North America

will require the 115v setting. Most

European countries and other Asian

countries will require 230v. We

recommend that you plug the G5.2 into an unswitched outlet, or a

switched outlet that will always be left ON.

There is an on/off switch for the power amplifier. This switch should

always be left on. The built-in amplifier has an auto-sensing circuit

that will automatically put the amplifier on stand-by when there is no

music being played for around 10 minutes. It will immediately switch

the amplifier on if there is music sensed.

Source Input Connections

Connect the output of your power amplifier to the High Level Input

binding posts using a high-quality loudspeaker cable. Make sure that

ver 1.0

~ÄëçäìíÉ=ÑáÇÉäáíó™

you have the correct polarity connected for both speakers – the plus

or positive (red) terminal on the G5.2 should be connected to the

plus, positive, or red terminal on your power amplifier.

The Bass Input selector switch should be in the up position –

pointing to the inputs being used. This is the recommended hook-

up, both sonically and for convenience.

Nevertheless, you may wish to connect the bass section of the

G5.2 directly to your preamplifier instead. You may wish to do this

if you know that your power amplifier may be deficient in the bass,

or does not have a response flat down to 20Hz. Also, check for the

phase correctness of your power amplifier. If your power amplifier

inverts phase, you will need to invert the high-level inputs when

you connect the bass section of the G5.2 directly to the preamp.

If you do this, use a good quality balanced interconnect cable to

connect the balanced output of your preamplifier to the Preamp

level input XLR connector on the back plate of the G5.2. Using this

connection, switch the Bass Input Selector to the down position.

This will bypass the high-level input from the servo amp, and take

the bass input for the built-in servo bass amplifier directly from the

preamp.

If your preamplifier does not have a

balanced output, you may elect to use

a single-ended to balanced pass-

through converter. High quality ones

may be obtainable from Balanced

Audio Technology, Cardas, or your

favourite supplier. Reasonably good

ones can also be obtained from Radio

Shack.

If you are planning to use long runs (over 10 feet) of interconnects

to connect the line-level inputs of your G5.2 to your preamplifier,

and your preamplifier does not have balanced outputs, we

recommend that you use an active (or passive) signal-balancing

device (such as from Rane Corporation) to convert the single-

ended output from your preamplifier to a truly balanced signal.

Such a signal will give you the benefit of maximum noise rejection

and maximum signal fidelity over longer runs.

Controls

The knob on the upper middle marked

“Bass Gain” controls the volume of the

built-in bass servo amplifier. Begin with this

control at position 7. The knob on the upper

right marked “Low Pass”controls how high

the woofer will play. At the extreme low of

71Hz, the woofer will play up to 71Hz, and

then begin rolling off, or reducing its volume,

above this frequency. The recommended

beginning position for this control is 90Hz.

The lower left knob marked “Tweeter” is a

volume control for the front tweeter. Turning

this control clockwise will increase the level of the front tweeter.

Use this control if you need a bit more treble or to increase the

apparent space of the soundstage. Start with this control at the

two o'clock position. There is about a one dB range for this

control.

The lower right knob marked “Midrange”is used to adjust the

level of the midrange. Start at the 12 o’clock position. Turning the

control anti-clockwise (or counter-clockwise) will make the

midrange sound leaner, and turning it clockwise will make the

midrange sound fulller. There is about a one and a half dB range

for this control.

Tuning the system

Music is the best way to begin your setup procedure. We suggest

that video sources be used only after you have setup the system to

properly reproduce music.

We suggest that you start with a single vocal with instrumental

accompaniment because the sound of the human voice is more

easily recognizable than many instruments and is the least

complex sound to deal with.

ver 1.0

~ÄëçäìíÉ=ÑáÇÉäáíó™

Adjusting Bass Gain

Leave the low pass filter alone for the moment, as it should remain

set at approximately 90 Hz. This control will be addressed later.

Turn the gain control of the woofer amplifier up or down until the

voice sounds correct. Whatever controls you use, turn them up and

down only a little at a time. It is easy to turn it up or down too much.

Concentrate on the mid bass regions (as opposed to the very low

bass in your recording) to achieve a natural blend. The voice and the

music accompaniment should sound as if it were cut from one cloth,

not separate.

If the voice sounds “thin” or does not have enough “chest” to its

sound, turn the woofers amplifier’s gain up till it does. If you find that

turning the volume up creates too much low bass, you will then need

to work on the low pass filter.

Low Pass filter

This control will lower the frequency cutoff point of the woofer.

Turning the low pass filter up to a higher number will extend the

upper bass regions without affecting the low bass level. Some rooms

may require you to set the low pass filter up to 130Hz. Do not be

afraid to increase this control to give the sound more body.

Next, set the woofers using more than just a voice. Select some

music that you know to have good deep bass. Set the gain on the

woofers for a natural and powerful bass sound. Use a symphonic

piece of music if you can, or use a natural bass instrument for your

guide. Try to make it sound real. You may have to return to the vocal

to make sure you have not gone too far in one direction.

At this point, if there is not enough mid bass, turn the low pass

number to a higher position or, alternately, position the main

speakers closer together in order to achieve better mid bass

coupling between the main speakers. If it sounds too “fat” turn the

low pass control down or adjust the volume. Small rooms have more

bass gain, hence the smaller the room, the higher the low-pass

frequency to use, and the lower the bass gain level.

Imaging and Soundstage

If your vocal selection is a well-recorded audiophile CD or LP, the

performer should appear to come from behind the loudspeakers and

ver 1.0

~ÄëçäìíÉ=ÑáÇÉäáíó™

be at the appropriate height for a standing person. If it is not, there

are several remedies that will address this.

If the vocal appears to be larger than life, you should first check the

system volume. Is it a volume that would be appropriate for

someone actually singing in your room? If there is too much

volume the artist will appear too big and the opposite is true

for too little volume. If the volume is set correctly and the image is

still too big, place them closer together and re-listen. Place the

speakers no less than 5 feet apart. If the image is still too big, toe

the speakers in a slight amount.

Conversely, if the image is too small, move the speakers apart.

The speakers should be no more than eight feet apart. Repeat

this process till you have it right. If the voice is too low in height,

turn the midrange control up (turning the knob clockwise) and the

image of the voice will move upward slightly.

If you have the speakers 20% of the way into the room, and you are

not getting enough front to back depth (the singer not appearing

behind the speaker enough) pull the speakers away from the front

wall a little bit at a time. If you do not have them pulled far enough

away, you may not have enough front to back depth. However,

slightly more than 1/3 of the way into the room is about as far as

you want to go. Pulling them half-way into the middle of the room

is unlikely to help (and probably incur the wrath of your spouse).

Find the best compromise for your room, your tastes and your space

requirements. If you are not getting proper focus on the voice, you

may angle the left and right speaker up to about 15 to 20 degrees

(toe-in) towards your listening position until you have a properly

defined center image. If the speakers are too far apart you will lose

the side image and if they are too close together you will have too

small a center stage.

When properly set up very little sound should appear to come

directly from the speaker, instead, the sound stage should extend

far beyond the left and right edge of the loudspeakers and they

should have tremendous front to back depth. When the recording is

close miked (when the instrument or performer is very close to the

recording microphone) the music may appear to come directly

from the loudspeaker. This is normal. Typically, however, the sound

should appear to be detached from the loudspeakers.

ver 1.0

~ÄëçäìíÉ=ÑáÇÉäáíó™

A simple rule of thumb to follow is that focus will be achieved by

placing the speakers closer together or farther apart, and front to

back depth can be adjusted by the distance from the rear wall.

Further, as the system “breaks in”, the depth and width of the

soundspace will increase and so will the “smoothness” of the sound.

Tuning into the room

There are no absolute rules concerning the speaker/room

coupling, so do not be afraid to experiment with speaker

placement for best results. You should also experiment with

asymmetric positioning in the room. Do not have your speakers

the same distance from the side walls – try putting them closer to

the left or the right wall. If the speakers are equidistance from side

and front wall, you may find a suck-out at 100Hz to 300Hz.

In some problematic rooms a resonance may develop at one or

two frequencies that is unnatural to the music. By moving the

speakers closer to the front/side wall or farther from the front/side

wall, the resonance may be reduced at the listener’s position.

Ultimately, it is all about balance. You have a number of controls

at hand with which to adjust the bass response, the low-pass filter

frequency and woofer volume. You can also move the speakers

closer together (for better speaker to speaker coupling), or further

apart.

Home Theater and Multi-Channel Music

While the Genesis 5.2 was designed with the audiophile in mind, its

performance and features make it ideal for Home Theater as well.

The G5.2 is truly a full frequency loudspeaker that satisfies the

requirement for Dolby Digitaland DTScinema reproduction.

However the combination of the low frequency capability and a

unique set of controls and connections on the G5.2 provide Home

Theater users benefits beyond other loudspeakers on the market.

In essence, the G5.2 has a servo-controlled subwoofer already

included in each speaker. This capability allows the G5.2 to provide

the ability to reproduce the low frequency effects (LFE) signal

available on all modern movie decoders. An additional benefit of

using this feature is that the LFE will come from two, or more,

locations in your room versus using a single subwoofer for LFE.

Utilizing this capability dramatically reduces room bass mode and
