A Message from Genesis

Congratulations! You are now the owner of the finest loudspeaker
system in the world. The Genesis Advanced Technologies 1.1
Loudspeaker System is the embodiment of our philosophy of

“

absolute fidelity

faithfully, with no compromise, in your home. With its vast abilities, the
Genesis 1.1 is also able to deliver sound as the filmmaker intended in
home theater applications.

The Genesis 1.1 is commissioned for the most discerning music
lovers in the world. Every system is custom made and unique. It is the
state-of-the-art in transducer technology and craftsmanship.

A Short History: In June 1979, Mr. Arnie Nudell, the founder of
Infinity Systems and Genesis, headed a small team at Infinity that
conceived and created the remarkable Infinity Reference Standard
(IRS). This soon came to be known as the world’s ultimate reference
system for the reproduction of music. Fourteen years later in June
1993, Nudell, in collaboration with Paul McGowan, introduced to the
world the Genesis 1 – a new benchmark for the reference
loudspeaker system.



” – the ability to reproduce any musical event

The current Genesis 1.1 embodies over 20 years of evolution and
revolution in loudspeaker design. It is the current ultimate reference
for the reproduction of music. Whereas many other products might
excel in one or more key areas, the Genesis 1.1 excels in every
important aspect of sound reproduction:

Spectral Coherence: The sound must be seamless, as if the lowest
bass frequencies were cut from the same cloth as the highest
frequencies.

Harmonic Structure: All instruments must be readily identifiable by
their harmonic content. There must be a uniformly consistent energy
vs. frequency ratio throughout the entire audio spectrum with uniformly
low distortion in order for this to be achieved.

Macro Dynamic Capability: Sometimes characterized as “dynamic
range”, macro-dynamics can be best defined in musical terms – from

mezzo forte (mf or medium-loud), to triple forte (fff or very loud).

Ver 2.0

~ДлздмнЙ=СбЗЙдбну

Micro Dynamic Capability: This describes the ability of a system to
resolve the lowest level material with as much articulation and imaging
as it does at the louder levels. The most difficult areas for loudspeaker
systems to reproduce well are the extremes, i.e. the micro-dynamics

from ppp to p (pianissimo to piano), and the last part of the macro-
dynamics f to fff (forte to triple forte).

Imaging and Soundstaging: A reference system must be able to
recreate a deep, tall and wide soundstage with accurate imaging
when reproducing recordings that contain such information. The effect
is that of being able to clearly distinguish the specific locations
(left/right, forward/back, height) at which the instruments are playing,
and to be able to hear their performance from the perspective of the
venue in which it was recorded.

These concepts can be understood in a basic sense by examining the
temporal coherence of a loudspeaker system. If each frequency of the
audio spectrum arrives at the listener at the same time, spatial cues
emanating from a performance are reproduced, i.e. sound waves
bounced from the walls, floor and ceiling of the venue, attenuated in
amplitude and displaced in time, can be resolved in space by two
stereo channels. If a reference system can slice time “thinly enough”,
and have excellent low-level resolving power, one can experience
many such bounces off surfaces; all displaced correctly in time,
ultimately defining the soundstage.

Low Harmonic and Intermodulation Distortion: The greatest sound
pressure peaks should create almost no distortion whatever. Many
loudspeakers begin to experience signal compression at loud levels.
When this happens, music becomes distorted as sounds compress.
Reference systems cannot exhibit these symptoms. Just as live music
sounds relaxed at the loudest levels, so must the reference system.

1 Set-up Guide

Now that you have your new Genesis 1.1 loudspeaker system, we
realize that you can’t wait to hook it up and start playing! However, this
is a big, complex system. There is no “quick” set-up.

You will need at least three immensely strong people. Be prepared to
allocate 5 to 8 hours to the initial unpacking, set-up and configuration.
Mentally condition yourself for hard, manual work that must also be
done carefully and precisely so as not to hurt your precious new
acquisition.

1.1 Unpacking

The Genesis 1.1 system is packed in eight (8) wooden shipping crates
and four (4) cardboard boxes. There are two crates containing a
woofer tower each, two midrange/tweeter wing-panel crates
containing two wings per crate, two crates each containing the
midrange ribbon and tweeters mounted on a Corian™ panel, a crate
with the two midrange/tweeter wing bases, and another one with the
two woofer tower bases. There will also be a box containing two
crossover boxes, two boxes each holding a 6-channel servo­controlled bass amplifier, and a box containing all the supplied
connecting cables.

To remove the contents of all the crates, you will need at least three
immensely strong people – the Genesis 1.1 loudspeaker system
weighs a total of 2,640 lbs (1,200kg) – to move the various parts of the
speakers around. We cannot be held liable for damage to either the
speakers or your backs during unpacking and setting up.

First, determine where you will be placing the speakers. They are
extremely heavy, so some forward planning will come in handy.
Depending on the surface they are set on, you may find that the
speakers are impossible to shift after setting up. Please see the
section on placement and carefully mark up the places where you will
set the four columns.

Start by un-boxing the woofer tower and wing bases. These are
the small, flat wooden the crates. Unscrew the plywood top and
remove. You will want to use a fully-recharged mechanical
screwdriver for this as there are many, many long tightly
inserted screws to be removed.

Undo the lag bolts that hold the bases to the crate. Remove the bases
one at a time and set them down where the woofer towers and wings
will go. Verify that the positions are accurately aligned as it may be
impossible to move them later.

Next, remove the woofer towers from their shipping crates. These are
the largest of the wooden crates. Position the crate near where you
have put the woofer tower bases. You do not want to move the woofer
tower very far once it is out of the crate. Either woofer tower can be
used on the left or the right, so just pick one.

First, remove the screws holding the top lid down
and open the top of the crate. Remove the woofer
grill cover and put aside safely.

You may be surprised to see that the woofer tower
is not wrapped in anything. This is to allow safe
handling of the tower. If there is anything covering
the veneer, it may be difficult to pick up this
immensely heavy tower. The covering may tear,
causing you to drop the tower. The soft foam
cushioning is sufficient to ensure that the veneer
finish is not marked.

Next, remove the screws holding one side of the
crate together. The woofer tower is then exposed and you can now lift
the tower out the front of the opened crate. It may be easier if you
dismantle all four sides of the crate if you do not have two immensely
strong people capable of lifting the woofer tower by themselves. With
the sides removed, four people can lift the tower out of the crate and
onto its base.

Determine which side is the top,
and which the bottom. The
bottom of the woofer is covered
with soft felt, and the top is
covered with veneer. Pick up the
woofer tower, place the bottom
on the base and stand the tower
up.

Set up the other woofer tower in
the same way. You should flatten

all crates and store them safely, in case you need to move these
speakers some time in the future.

Next, set up the midrange/tweeter wings. The wings
are marked left and right, so set them up on the
correct side. First locate the crate containing the left
wings, and locate the corresponding Corian panel.
The left Corian panel will have the column of tweeters
to the right of the midrange ribbon.

Unscrew the top of crates and remove the lids. First,
remove the Corian panel with the tweeters and
midrange and insert it into the center part of the base.
Have someone hold the panel in place until the wings
are put in place. The wings hold the panel up, and if
the panel tilts too far front or back, the bottom might
break off.

Then, while someone else holds the panel vertical,
place one of the veneer/mdf wings into the slot beside the panel.
Once both wings are in place, screw the three parts together. Make
sure that the tweeters are on the inside – ie. the row of tweeters are
closer together than the midrange ribbons.

Insert all 12 screws provided (with the
washers) from the back through the
holes in the wings into the inserts on the
Corian panel. Finger-tighten the screws,
taking care to seat the screws properly
into the brass inserts. You may have to
move the panel forwards and
backwards slowly to align all the screws
properly.

Once all 12 screws are in, you can then
tighten them to make the surface of the

wings flush with the Corian panel. Do not
over-tighten. The screws are just used to
hold the wings and panel vertically in
place. The curve of the wings provides
most of the structural strength.

1.2 Placement of the Genesis 1.1 Loudspeaker

The G1.1 requires a large room in order to give the speaker ample
space from the walls so that it can perform at its best. A typical room
size is 29 ft x 48 ft with 12 ft ceilings.

A good starting position for the midrange/tweeter panels is 15 feet into
the room as measured from the front wall (the wall behind the
speakers which you look at as you are seated listening to the
speakers) to the face of the speakers. You will want to sit 18 feet away
as measured from the face of the speakers to the ears, and have
approximately 15 feet (if available) behind you to the rear wall. Place
the column of tweeters on the inside, and position the mid/tweeter
panels so that the centers of the tweeters are 6 feet 10 inches apart.

Next, position the woofer towers just to the outside of, and behind the
mid/tweeter wings. Having the woofers diagonally six feet behind the
midrange/tweeters work well. Placing the woofer towers asymmetric in
the room results in a smoother bass response than if the woofers are
symmetric. If you have a much more space and a wider room, the
woofer towers can be also be positioned outside the mid/tweeter
wings in an arc such that the center of the woofer cone and the
tweeters are equidistant from the listeners.

Typical room placement: Place speakers and

listeners about 1/3 of the way into the room

Tweeters
6’ to 8’

1/3 or 20% 1/3 or 20%

~ДлздмнЙ=СбЗЙдбну

For some rooms, there may not be enough space and you will have to
adjust as you see fit. In a smaller room, the speakers can be just 20%
of the way into the room, and the listening position can then be 20%
from the rear wall. (see the diagram above). If you have to sit less
than 10 feet in front of the speakers, you have too small a room to
accommodate the Genesis 1.1’s.

1.3 Woofer Connections

Included with your Genesis 1.1 is a set of four large
cables (with 3 channels each) used to connect the
woofers. Each end of the cable is clearly marked,
"amplifier" or "speaker" in red or white lettering.
Use the set with red lettering for the right channel
and white lettering for the left channel.

Connect the appropriate ends to your Genesis
Servo-controlled Bass amplifiers, and the rear of the
woofer towers. It does not matter which connector
is attached to which woofer as long as the left/right
channels and cable direction are correct.

For interest and reference, the connectors are
numbered 1 thru 6 from left to right and top to bottom.
Woofer number 1 being the top woofer, and woofer
number 6 being the bottom woofer.

When you connect the

woofer tower outputs
pay close attention to the way the
connector works. The connector is a
Neutrik™ Speakon™, it only goes in one
way. You cannot put it in wrong, but you
can fail to put it in all the way. Push the
plug in, and twist it clockwise until the lock
clicks.

At the amplifier end of the cables, you will
notice that there are “flying leads” coming
out of the Neutriks all terminating in a little
silver jack per cable. These are grounding
jacks for the internal shield of the cables.
These can be plugged into a termination
female jack that is attached to the chassis
of your amplifier. This is necessary in a
high-static environment, or if there is
