a bs o l u t e f i d e l i t y ® A Message from Genesis Congratulations! And Thank You! You are now the owner of one of the finest loudspeakers in the world! The Genesis 2.2 junior (or G2jr) is the result of technologies developed and refined over the past 40 years in constant production. The G2jr loudspeaker is designed to reproduce music (and film) at live listening levels with virtually no restrictions on dynamic range, frequency response, or imaging capabilities in a medium to large room.
a bs o l u t e f i d e l i t y ® Please write the purchase details of your Genesis 2.2 Junior here for future reference. Remember, send in your registration card to extend the limited warranty on your loudspeakers. Bought from: ____________________________ ____________________________ Date: ___________________________________ Serial Numbers: Warranty Statement and Extended Registration Card should be placed here. Please check with Genesis should they be missing.
a bs o l u t e f i d e l i t y ® Set-up Guide Now that you have your new Genesis 2 junior loudspeaker, we realize that you can’t wait to hook it up and start the music! However, we want you to set it up correctly to derive the greatest enjoyment from your purchase. 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.
a bs o l u t e f i d e l i t y ® damage (to either the speakers or your backs!) during unpacking and setting up. As the speaker tilts up and out of the crate, and it is extremely heavy, we suggest that you position the crate approximately at the final position where you want the loudspeaker to be. The top, front and one side forms a 3-sided lid to the crate. Once this is removed, the speaker can be easily tilted up and out of the crate.
a bs o l u t e f i d e l i t y ® Loudspeaker Controls You will notice four control knobs on the back of the G2jr. These are labelled “BASS GAIN”, “LOW PASS”, “TWEETER” and “MIDRANGE”. Set them initially pointing straight up – the 12 o’clock position. This is the nominal flat position and will work for the majority of installations. For a minimum-sized room, the bass gain should be set at 3 (the 9 o’clock position). Ver 1.
a bs o l u t e f i d e l i t y ® 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 snapping sounds. This is caused by the amplifier limiting current to the woofers (much like the over-rev fuel-cut off in car engines). If that happens, turn down the volume of your system to protect your hearing and your speakers.
a bs o l u t e f i d e l i t y ® 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 G2jr after at least 50 hours of running-in, further fine-tuning of your system may be necessary after 800 hours or so. As the loudspeaker system breaks in, it will sound better and better.
a bs o l u t e f i d e l i t y ® advantages is that the sound pressure level does not fall as fast with respect to distance as it does for a point source. Because a line source radiates sound in a cylinder and a point source radiates sound in a cone, with a doubling of distance from the loudspeaker, a line source attenuates by 3dB whereas a point source attenuates by 6dB.
a bs o l u t e f i d e l i t y ® The low-pass control will raise or lower the frequency cutoff point of the woofer (not the crossover frequency between the bass and midrange). Turning the low pass filter up to a higher number will extend the upper bass regions into the midrange without affecting the low bass level. Some rooms may require that you set the lowpass filter to 115Hz or more. Do not be afraid to increase this control to give the sound more body.
a bs o l u t e f i d e l i t y ® actually singing in your room? If there is too much volume the artist will appear too big and the opposite is true for too little volume. If the volume is set correctly and the image is still too big, toe the speakers in a very slight amount or place them closer together and re-listen. Repeat this process till you have it right. If the voice is too low in height, turn the midrange control to the next highest position and the image of the voice will move upward.
a bs o l u t e f i d e l i t y ® where the speakers are, but less dense between the center and the speaker. 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.
a bs o l u t e f i d e l i t y ® 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.
a bs o l u t e f i d e l i t y ® increments (approximately half an inch at a time) and return often to the recordings you have used to adjust the front to back depth and soundstage properties of your system. It is easy, yet unproductive, to go too far as you will create a boominess in the sound. 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.
a bs o l u t e f i d e l i t y ® 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.
a bs o l u t e f i d e l i t y ® 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.
a bs o l u t e f i d e l i t y ® The Technology The Genesis 2.2 junior loudspeaker integrates a line-source midrange/tweeter with point-source bass. Each speaker is over 6 feet tall, and the cabinet structured is designed to manage vibrations and resonance. The tweeters and midrange ribbon are mounted on a 1.5-inch slab of high-molecular weight cast acrylic, and are isolated from the box containing two horizontally opposed 12” woofers.
a bs o l u t e f i d e l i t y ® A second great 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.
a bs o l u t e f i d e l i t y ® 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.
a bs o l u t e f i d e l i t y ® This result 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. Thus further insulating the listener from the room’s negative effects, and enhancing the sense of spaciousness and depth.
a bs o l u t e f i d e l i t y ® 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. The system also drives the woofer to constant acceleration, which makes the frequency response of the woofer anechoically flat to the lowest frequencies.
a bs o l u t e f i d e l i t y ® The isolation, plus vibration-cancellation results in a stable, solid image even when there is heavy bass content in the music. 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.
a bs o l u t e f i d e l i t y ® 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. This ensures that all midrange frequencies are “dumped” below the base of the cabinet so that floor-borne vibrations do not affect the imaging and soundstage of the loudspeaker. 3) The spikes rigidly couple the suspension system to the floor.
