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 constant production.
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™
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 and horsepower, but they are very different vehicles and you wouldn’t use your Ferrari to move a load of gravel.

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 a minimum the room should be about 15 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
Ver 2.1 November 2009

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 equidistant from the midrange/tweeter wings will result in better integration of the bass frequencies to 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

abs o l u t e fid e l i t y
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, furniture, 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 optional Maximum Dynamic Headroom 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.
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
Ver 2.1 November 2009
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).

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 pre­installed 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" so that the suspension frame clears the carpet.
4) If you need to move the loudspeaker after you have installed the spikes, do not “walk” the speaker cabinet on the spikes – retract the spikes first, shift the speakers, and then lower the

abs o l u t e fid e l i t y
spikes again. This will avoid causing damage to the acoustic suspension and to your floor.
5) While the acoustic suspension is designed for you to be able to use the system on any surface, if you have very light and resonant bare 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, an acoustic suspension (or amplifier stand) plus a power supply unit and numerous supplied cables in the standard configuration.
The parts of the amplifier are:
Genesis 2 Servo-Controlled Bass Amplifier
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) One Acoustic Suspension system.
6) Two pairs of Servo-Bass Cables (SBC) with Neutrik
50-amp Speakon™ plugs at each end.
7) A Power Transformer for each Amplifier Module with
two Neutrik™ 20-amp PowerCon™ outlets.
8) A pair of Power Umbilicals with a Neutrik 20-amp
Powercon plug at each end (one grey and one blue).
As an optional upgrade, comprising two Maximum Dynamic Headroom Reservoirs and an additional Control Module is available. This conveys additional macro- and micro-dynamic

abs o l u t e fid e l i t y
capabilities to the servo-bass system. Having the extra Control Module also affords more fine tuning capabilities for the bass. This is particularly important with asymmetric rooms. With this upgrade, an additional Acoustic Suspension systems are supplied.
In the typical configuration, the Control Module, and two Servo­feedback Amplifiers are placed in a stack between the midrange/ tweeter wings. The Power Transformers are placed behind the stack. Using the supplied Power Umbilicals, connect the Power Supply to the two Amplifier Modules.
A word of caution – the Neutrik PowerCon connectors used for linking the power supply to the amplifiers are designed for passing current. They are not designed to make/break current. Hence, be sure to connect the Power Umbilicals before you connect the Power Supply to the wall outlet.
Using the supplied CIC, link the Control Module to each of the Servo-feedback Amplifiers. One amplifier module is for the RIGHT woofer tower and the other will be for the LEFT. This can be determined by the last letter of the serial number. It does not matter which CIC is used for the right channel 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 has a pair of 50 amp twist-lock Neutrik™ Speakon™ connectors, and is clearly marked,
AMPLIFIER
or
SPEAKER
. It does not matter which connector is used 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
AMPLIFIER
or
SPEAKER
in
red lettering, and the other in white
lettering.
When you connect the woofer tower outputs pay close attention to the way the connector works. It only goes in one way and you cannot put it in wrong. However, you can fail to put it in all the way

or fail to lock it in place. 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 disconnected. The shield ground should be used only when necessary.
Midrange/Tweeter Connections
Next, connect the mid/tweeter panels to your power amplifier using a pair of high quality loudspeaker cables (not supplied) to the 5-way binding posts. We recommend using good quality spade connectors for this job.
There are two ways to get the music signal from your hifi system to the Servo-Controlled Bass Amplifier to drive the woofers. The first, and preferred way is to drive it using the output of the power amplifier that is driving the midrange/ tweeter panels using the supplied pair of Servo-Bass Interconnects.
The Servo-Bass Interconnect will be supplied with a pair of banana plugs at one end, and an XLR balanced male plug at the other end. The banana plugs will plug straight into the binding posts of the G2 midrange/tweeter tower inputs when you are using speaker cables with spade connectors. If your speaker cables use banana plugs, you can order spade connectors with the SBI at no extra charge when you order your loudspeakers.
Servo-Bass Interconnects
parallels speaker cable inputs
The XLR connector contains a specially developed internal balancing circuit that enables the power amplifier to drive the balanced input of the servo amplifier. Because of the extremely high impedance of the balancing circuit, the parallel connection places absolutely no stress on the power amplifier. Do not use any
other interconnect cable for this purpose as the high level output
