A Message from Genesis
Congratulations! And Thank You!
You are now the owner of one of the finest loudspeaker systems in
the world! The Genesis 2.2 is the result of technologies developed
and refined over the past 40 years in loudspeaker design.
The G2.2 loudspeaker system was created for the music lover who
knows (almost) no compromise. 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
absolute fidelity™”, the ability to reproduce the musical event
“
faithfully, as was intended by the performer or filmmaker.
However, the G2.2 is not meant to reproduce music at ear-splitting
levels. If you are looking for just LOUD, this is the wrong
loudspeaker. A Ferrari and a Caterpillar may have the same price,
but they are very different vehicles and you wouldn’t use your
Ferrari to move gravel.
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

Please write the purchase details of your Genesis 2.2 System
here for future reference. Remember, send in your registration
card to extend the limited warranty on your loudspeakers.

Set-up Guide
Now that you have your new Genesis 2 loudspeaker system, we
realize that you can’t wait to hook it up and start the music!
However, this is a big, complex system and we want you to set it
up correctly and more importantly, safely. So, please read this set
up guide (even if your dealer is setting it up for you!) before you
proceed.
Planning the Placement
Before you even have the loudspeakers delivered, it would be a
good idea to make a plan of where you will place them. You will
not need a huge room, but at an absolute minimum the room
needs to be 16 feet (5m) wide where the speakers will be placed.
You should have a minimum of at least 6 feet (2m) of space behind
the speakers. The listening position should be a minimum of 10
feet (3m) from the front of the midrange ribbon to allow for proper
integration of the drivers.
In a typical placement, the midrange/tweeter wings will be placed so
that the two columns of tweeters are on the inside, and between six
feet to eight feet (2m to 2.6m) apart. The woofer towers are placed
behind and outside the wings with the column of woofers about 4 feet
1111
absolute fidelity
from the midrange ribbons. In order to allow for sufficient space from
the sidewalls, this dictates that the optimum room is at least 19 feet
(6m) wide.
Placing the woofer towers asymmetrical but equidistance from the
midrange/tweeter wings will result in better bass integration in the
room. Keep the side of the woofer towers no less than 16 inches
from the sidewall.
The suggestions here are typical in a minimum space. With a larger
room, it is possible (and optimal) to have a layout as shown below
with the midrange, tweeters and woofers equidistant from the
listening position. Still, the woofer towers should be placed
asymmetric in the room with the distances of the woofers from the
2222
absolute fidelity
nearest wall being different.
As the room will greatly influence the sound of your system, finetuning adjustments in placement will be necessary. Every room will
be different, with doorways, closets, wall construction and covering,
etc. all making a significant impact on positioning.
Unpacking
The Genesis 2.2 system will arrive in a number of pieces. There
are four large wooden shipping crates, two containing the woofer
towers, two holding midrange/tweeter panels (or “wings”). There
will also be a pallet of cardboard boxes holding the acoustic
suspension system, the various modules of the servo-controlled
bass amplifier, and a box containing the various cables. (There
could also be up to three more boxes if you have the dynamic
reservoir and power supply upgrades to the servo-controlled bass
amplifier.)
To remove the contents of all the crates, you will need help. The
G2.2 loudspeaker system with crates weigh a total of 1,400 lbs.
Each woofer tower weighs over 220 lbs, and each tweeter tower
weighs over 150 lbs and they have to be lifted out of the shipping
crates. We are not liable for damage (to either the speakers or
your backs!) during unpacking and setting up.
We suggest the use of a forklift to move these
crates around, and at least four strong people to
un-box and position the loudspeakers. In order to
remove the loudspeakers from the crates, the front
and top of the crates can be removed. This is
secured with screws – remove all exposed screws
except the ones marked with blue paint – and the
top and front can be lifted away.
With the top and front of the crate removed, each
wing and tower of the loudspeaker can be carefully
lifted and slid out of the crate. Before you put the speaker up on its
feet, it will be necessary to install the acoustic suspension (next
page).
After unpacking, we strongly suggest that the crates be dismantled,
flattened and safely stored away in a cool, dry place. They will be
needed should you relocate or move. It will be expensive to custom
3333
absolute fidelity
build crates strong enough to transport these loudspeakers without
damage.
Assembling the Acoustic Suspension
Acoustic Suspension under the
midrange/tweeter wings
Should you be placing the speakers on a hardwood floor or a floor
that would scratch easily, do not use “spike cups”. These defeat the
purpose of having a spike in the first place! Use a copper penny –
the weight of the speaker on the spike will create a depression in
the penny, and this point is what will efficiently transfer vibration to
the floorboards.
A unique feature of the Genesis 2.2
loudspeaker system is the integration of an
acoustic suspension system for the
loudspeaker columns. This is an essential
feature of the cabinet structure – resulting in
lower coloration, better definition and rocksolid imaging.
The suspension system comprises of a
suspension frame made of 1-inch of solid
cast acrylic, a set of Neoprene decoupling
shock absorbers, and a set of steel spikes.
A couple of points to note during the assembly of the acoustic
suspension system:
1) The triangular “hole” in the suspension frame points to the
front of the speaker (towards the listener).
2) Do not over tighten the shock absorbers that are pre-
installed on the cabinet – finger tight is sufficient. A hex-key
(or allen wrench) is supplied to tighten the bolts holding the
suspension frame to the shock absorbers. Again, do not
over tighten these bolts.
3) The point of the spike should protrude through the
suspension frame only far enough to couple to the floor. If on
a concrete or marble floor, for example, 5mm or 1/5” is more
than sufficient. If you have your speakers on a 1/2" deep pile
carpet, then you will need to have the spike protrude about
3/4".
4) If you need to move the loudspeaker after you have installed
the spikes, do not “walk” the speaker cabinet on the spikes –
4444
absolute fidelity
(
)
retract the spikes first. This will avoid causing damage to the
acoustic suspension and to your floor.
5) If you have very light and resonant floorboards, you may
need to place a heavy slab of marble, slate, or granite under
the loudspeaker to avoid exciting the floor.
The Servo-Controlled Bass Amplifier
The included remote-controlled
modular Servo-Controlled Bass
Amplifier powers the woofer towers
of the G2. There are three modules
plus a power supply unit and
numerous supplied cables in the
standard configuration. Various
upgrades are also available for the
Servo-Controlled Bass Amplifier –
please check with your dealer.
The parts of the amplifier are:
Genesis 2 Servo-Controlled Bass Amplifier
with optional amplifier suspension for floor placement
1) The electronic crossover and Control Module with left
and right balanced inputs and two control outputs.
2) A pair of Control Interface Cables (CIC): these have
7-pin Neutrik™ connectors at each end.
3) A pair of Servo-Bass Interconnects (SBI) with XLR
connectors at one end and a pair of banana plugs (or
optionally spades) at the other end.
4) Two Servo-feedback Amplifier Modules with one
control input, and two Neutrik 50-amp Speakon™
outputs.
5) Two pairs of Servo-Bass Cables (SBC) with Neutrik
50-amp Speakon™ plugs at each end.
6) A Power Supply for the Amplifier Modules with two
Neutrik™ 20-amp PowerCon™ outlets.
7) A pair of Power Umbilicals with a Neutrik 20-amp
Powercon plug at each end (one grey and one blue).
In the typical configuration, the Control Module, and two Servofeedback Amplifiers are placed in a stack between the
midrange/tweeter wings. The Power Supply is placed behind the
stack. The standard cables supplied will work for this configuration:
9-foot (3m) Servo-Bass Cables (SBC), two-foot (0.6m) Control
5555
absolute fidelity
Interface Cables (CIC) and 6-foot (2m) Servo-Bass Interconnects
(SBI). An alternative placement option is to have the Control
module in the middle, flanked by the two Servo-feedback
Amplifiers, with the Servo-feedback Amplifiers closer to the woofer
towers and the Control module between the midrange/tweeter
wings.
First, place the stack of modules between the midrange/tweeter
wings with the Control Module on the top and the whole stack on
an amplifier stand. Using the supplied CIC, link the Control Module
to the Servo-feedback Amplifiers. One amplifier module is for the
RIGHT woofer tower and the other will be for the LEFT. You can
figure out which it is by the last letter of the serial number. It does
not matter which CIC is used for right and which is used for left.
However, one is marked with a red ring and the other is marked
with a white ring for convenience.
Use the SBC to connect the woofer
towers to the woofer amplifier. Each
end of the cable is clearly marked,
AMPLIFIER or SPEAKER. It does not
matter which connector is attached to
which as long as the correct amplifier
module is used for the left and right
towers. It does not matter which SBC is
used for the left or the right; however,
one is marked with
SPEAKER in red lettering, and the other
in white lettering.
AMPLIFIER or
When you connect the woofer tower outputs pay close attention to
the way the connector works. This connector is a 50 amp twist-lock
Neutrik™ Speakon™. It only goes in one way and you cannot put it
in wrong. However, you can fail to put it in all the way. Line up the
alignment pins on the connectors, push the plug in, and twist it
clockwise until the lock "clicks" in place to keep it there. By looking
carefully, it will be obvious as to how it works.
At the
AMPLIFIER end of the servo-bass cable, you will find a male 1/8”
jack. The female end is on the chassis of the servo-bass amplifier
labelled GND. These jacks are used for grounding an internal shield
within the servo-bass cable. For the time being, leave this shield
