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 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 r

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

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

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 (

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 rock- solid imaging. The suspension system comprises of a suspension frame made of 1-inch of solid Acoustic Sus

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 n

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 t

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 system to the Servo-Controlled Bass Amplifier to drive the woofers. The first, and preferred way is

Each end of the SBI has a grounding alligator clip on a flying green lead. Leave this grounding clip disconnected for the time being. It is not necessary in most instances. The alternative method of connecting the servo-bass amplifier to your system is to use a pair of balanced in

Set the phase to zero as an initial setting. (If you are not driving the servo-bass amplifier as recommended using the output of the power amplifier, the phase will depend on the phase shift and group delay of your power amplifier. A typical value will be 45 to 135 degrees.) The high-pass (HI HI HI HI) filter dete

absolute fidelity Position two gives you a soundstage perspective of about the middle of the concert hall. Position three is more like the orchestra seats, and position one may be more like the circle seats. While it is relatively easy to put the Genesis 2 loudspeaker system into your room and system and get a reasonable sound, it is not as easy to perfectly integrate the loudspeakers into your room, and get great music out of it. The time you will take to do this properly will be wel

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. Fine-tune your system only after at least 200 hours of play. As the loudspeaker system breaks in, it will sound better and better. Using the IsoTek Full System Enhancment CD will shortcut the 200 hours needed. Begin with the bass level Start with a single vocal with simple instrumental accom

If, at this point, it does not have 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. At this point it is suggested to use the low pass f

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.

Further adjustments With the woofer towers positioned in the recommended placement behind and outside the midrange tweeter panels, low bass in the room should not be a problem. Should you have too much bass, simply turn the volume down on the remote control. Too little, and the opposite will apply. In general, the low-pass filter and t

absolute fidelity The Refinement stage After following the rough setup guide above, you may not be completely satisfied with the results. We share with you here some of our observations in setting up these loudspeakers. Make One Change At A Time One rule of thumb you should always keep in mind. Make one change at a time! Do not, for instance, change position of the speakers and make an adjustment to the amplifier all at once. Make each of these changes separately and note the differe

absolute fidelity should be close enough together to achieve proper "coupling" of the midrange ribbon driver. Coupling is desirable in the lower frequencies from the mid-bass on down. This simply means that the left and right drivers "work together" as opposed to working separately. If you find there isn't enough deep bass, your first remedy is the volume control on the woofer amplifier. This has several limitations. First, turned up too high, you may get some distortion on very low
