absolute fidelity Owners Manual and Set-up Guide Genesis 2.
absolute fidelity 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.

absolute fidelity 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.
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 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.
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, 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”).
absolute fidelity build crates strong enough to transport these loudspeakers without damage. Assembling the Acoustic Suspension 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.

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.

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. Using the supplied Power Umbilicals, connect the Power Supply to the two Amplifier Modules.

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.
absolute fidelity 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.

Bass Control Adjustments Your servo-bass amplifier should be the last thing you turn on in your system, and the first thing you turn off.
absolute fidelity good place to start when making adjustments. In general, a lower bass volume setting is needed in smaller rooms. Next, adjust the phase with the buttons marked “ ” or “ ” on the remote control. When you first press the phase up or down button, the display will flash Ph and then the current phase setting will be shown. The next press of the button will move the phase up or down. Set the phase to zero as an initial setting.

Midrange/Tweeter Controls You will notice two controls on the back of the midrange/ tweeter panel. The left hand knob is a trim control for the rear tweeters. Turning this control clockwise will increase the level of the rear tweeters. If there is not enough space behind your loudspeaker, the rear tweeter control can be turned down. In large rooms, the tweeter control can be turned up.
absolute fidelity Servo-Controlled Bass Amplifier Protection The servo-bass amplifier has numerous protection circuits built in to protect both the amplifier and the woofers. If you over-drive the amplifier, it will self-protect and you will hear clicking or thumping sounds. This is caused by the amplifier limiting current to the woofers (much like the over-rev fuel-cut off in sports car engines). If that happens, turn down the volume of your system to protect your hearing and your speakers.
absolute fidelity Tuning the system Music is the best way to begin to fine-tune your setup. We suggest that video sources be used only after you have setup the system to properly reproduce music. While we deliver the G2 system only after at least 24 hours of running-in, fine-tune your system only after at least 200 hours of play. As the loudspeaker system breaks in, it will sound better and better.
absolute fidelity 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. If, at this point, it does not have enough mid bass, turn the low pass number to a higher position or, alternately, position the midrange/ tweeter wings closer together in order to achieve better lower midrange coupling between the main speakers. If it sounds too “fat” turn the low pass control down or adjust the volume.
absolute fidelity panels 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. If you get the speakers much beyond 1/3 of the way into the room, it is unlikely that pulling them further away is reasonable. Too much absorption on the wall behind the speakers will also result in less depth in the soundstage. The G2 requires a relatively “live” front wall.
absolute fidelity anywhere from 45 deg to 135 deg (or require that the input to the Control Module be phase inverted if the power amplifier used is phase inverting). Now that you have roughed the system in, you may want to experiment with different phase angles. Using the remote control you can adjust the woofer's phase angle up and down in fivedegree increments. The changes are subtle and they usually affect the imaging and soundstage.
absolute fidelity position. There are no absolute rules concerning problematic rooms, so do not be afraid to experiment with best woofer placement. 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 coupling), and also move the woofer towers closer together, or further apart, or even move them closer to a corner of the room for more bass.
absolute fidelity one panel, listen, and then move the other panel. You may also find an asymmetric placement in-room more accurate and pleasing. Defining the Soundstage A common problem we find with many set-ups is a tendency to separate the speakers too far from each other. This gives an unnaturally stretched soundstage between the two speakers, and creates problems with focus. The key problem is a lack of soundstage information beyond the left and right sides of the speakers.
absolute fidelity front to back depth and soundstage properties of your system. It is easy, yet unproductive, to go too far in one direction (and if you move the woofer towers too far from the wall you may lose low bass extension and if they are too near the walls, you will create a boominess in the room). Secondly, you may make the mid bass produced by the top of the woofer out of proportion with the mid bass produced by the bottom of the midrange ribbon.
absolute fidelity important. Generally speaking, the Genesis loudspeakers prefer a live front wall. By these terms we mean the amount of reflection of sound. A typical wall of glass or, brick, cement or drywall material is a reflective surface. A heavily curtained or sound proofed wall would be considered a "dead wall" or a non-reflective wall. A normal thin curtain across a window causes only a small amount of absorption. 2. Sidewalls. Because the speaker is a dipole it is less sensitive to the sidewalls.
absolute fidelity you listen to has a similarity of sound (too much or too little of a certain frequency for instance) then you can be fairly certain that you have yet to perfect your set-up. Keep at it and remember to enjoy your music as you work on perfecting your set-up. During the design stage of Genesis loudspeakers, we rely on hundreds and hundreds of hours of critical listening. There are changes we can make to the crossover that we can measure, but can hardly hear the difference.
absolute fidelity The Technology The Genesis 2.2 loudspeaker comprises four “towers”: two midrange/tweeter wings and two bass columns. Each tower is over 6 feet tall (183cm), and the cabinet is made of a vibration damping and resonance-control acrylic/composite sandwich material. The tweeters and midrange ribbon are mounted on a solid 1.5-inch slab of high-molecular weight cast acrylic.
absolute fidelity floor or the ceiling. No deleterious interference from these surfaces is created (as in virtually all other kinds of speakers). Another advantage of the line source is that the vertical spectral content of music is virtually the same throughout the length of the line source. Hence, the seating height does not matter with this speaker; unlike point source speakers where it is important for the ears to be aligned in relationship with the tweeter.
absolute fidelity there are far fewer detail-robbing room reflections from the room than other types of loudspeakers. With fewer spurious reflections to confuse your hearing, the program source emerges more clearly. Imaging is deeper, yet more focused. This results in a loudspeaker system that is virtually roomindependent. Also, because there are no phase and frequency distorting reflections created, one can be transported into the audience of the actual concert hall where the music was recorded.
absolute fidelity thick. The ribbon is then suspended in the magnetic field created by over 24 feet of barium ferrite magnets. This results in a perfect line-source ribbon generating a continuous and perfectly coupled wave front. The benefit of this to the listener is a wide and even horizontal dispersion yielding a large and highly stable sweet spot. As a line-source dipole, the midrange ribbon has a vertical dispersion pattern identical to that of the line array of tweeters.
absolute fidelity moving and applies a counter-signal to stop the woofer faster and more effectively than an open loop woofer could possibly respond. Thus, the servo-drive reduces distortion and improves transient response by making the woofer appear to be massless. Typical non-servo woofer systems have distortion levels that exceed 10% at even moderate levels. The Genesis servo bass system reduces this distortion to below one percent at almost any output level.
absolute fidelity enclosure all work together in unison to produce bass output that descends evenly to below your hearing limits. Servo-controlled Bass Amplifier One problem, however, of metal cones, is that of greater mass – even ones as light as the ones used by Genesis. To over come this, we had to build an amplification system of great power, and high damping factor.
absolute fidelity The Acoustic Suspension The suspension for each loudspeaker tower comprises three elements: 1) The neoprene vibration absorbers are tuned to isolate and decouple the loudspeaker cabinet for optimal imaging and bass response no matter what surface the loudspeaker sits on. 2) The skeletal frame acts as a tuned absorber. Made of an inch of solid acrylic, no two parts of the frame will resonate at the same frequencies.
