~ÄëçäìíÉ=ÑáÇÉäáíó™ A Message from Genesis Congratulations! You are now the owner of one of the finest loudspeaker systems in the world! Based on the technologies developed for our flagship Genesis 1.1, the G5.2 is a smallish 4-ft tall floor-standing loudspeaker, and yet it delivers some of the imaging and soundspace of our largest 7-foot tall products. The G5.2 loudspeaker system was created for the music lover living in the metro-environment. It is designed to reproduce music (and f

~ÄëçäìíÉ=ÑáÇÉäáíó™ A Quick Start Set-up Guide Now that you have your new Genesis 5.2 loudspeaker system, we realize that you can’t wait to hook it up and start playing! However, please read this quick set up guide (even if your dealer is setting it up for you!) before you proceed. Unpacking Your loudspeakers will come to you in two large shipping cartons. The G5.2s weigh over 140lbs (63.5kgs) each, so we suggest a minimum of two strong people to move the speakers around. We will not

~ÄëçäìíÉ=ÑáÇÉäáíó™ Set-up Guide Positioning A good starting position for the G5.2 is about 20% of the way into the room as measured from the front wall (the wall you look at as you are seated listening to the speakers). Start with the speakers six feet apart, and not toed-in. You will want to sit 10 to 12 feet away from the speakers (if you have the space). We will experiment with moving the speakers around, and toeing them in later. Power Connections There are two connections you

The Bass Input selector switch should be in the up position – pointing to the inputs being used. This is the recommended hook- up, both sonically and for convenience. Nevertheless, you may wish to connect the bass section of the G5.2 directly to your preamplifier instead. You ma

~ÄëçäìíÉ=ÑáÇÉäáíó™ Controls The knob on the upper middle marked “Bass Gain” controls the volume of the built-in bass servo amplifier. Begin with this control at position 7. The knob on the upper right marked “Low Pass”controls how high the woofer will play. At the extreme low of 71Hz, the woofer will play up to 71Hz, and then begin rolling off, or reducing its volume, above this frequency. The recommended beginning position for this control is 90Hz. The lower left knob marked

~ÄëçäìíÉ=ÑáÇÉäáíó™ Adjusting Bass Gain Leave the low pass filter alone for the moment, as it should remain set at approximately 90 Hz. This control will be addressed later. Turn the gain control of the woofer amplifier up or down until the voice sounds correct. Whatever controls you use, turn them up and down only a little at a time. It is easy to turn it up or down too much. Concentrate on the mid bass regions (as opposed to the very low bass in your recording) to achieve a natural b

If the vocal appears to be larger than life, you should first check the system volume. Is it a volume that would be appropriate for someone 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, place them

~ÄëçäìíÉ=ÑáÇÉäáíó™ A simple rule of thumb to follow is that focus will be achieved by placing the speakers closer together or farther apart, and front to back depth can be adjusted by the distance from the rear wall. Further, as the system “breaks in”, the depth and width of the soundspace will increase and so will the “smoothness” of the sound. Tuning into the room There are no absolute rules concerning the speaker/room coupling, so do not be afraid to experiment with speaker placem

LFE Input The Low Frequency Effects (LFE) input allows the G5.2 to be used in addition to, or in place of, a separate sub-woofer. The LFE input blends the low frequency effects signal from the home theatre processor into the woofer section of the speakers. The LFE input bypasses the internal crossover, and hence uses the home theatre processor’s crossove

However, having the LFE gain control allows you to tune the LFE if your two systems have completely different gain structure. LFE Output Along with the LFE input, the G5.2 has a unique capability of LFE output. This is a true powered balanced output, and hence, can convert a single-ended input signal into a true balanced output. This buffered output can be used to daisy-chain th

A word of caution, however, if you move the speakers too far from the front wall you may lose focus. Yet another problem is a lack of mid bass energy. In order for the appropriate amount of mid bass energy to be present, the speakers should be close enough together to achieve proper "coupling" of the midrange driver and the mid-bass couplers. Coupling is desirable in the lower frequenci

~ÄëçäìíÉ=ÑáÇÉäáíó™ Room Treatment No room is perfect. To optimize your sonic presentation it may be helpful to treat your room. Here are some guidelines: 1. Front walls. This loudspeaker is a dipole and therefore there is sound coming from both the front and the back of the speaker. How the front wall is treated or not treated is important. Generally speaking, the Genesis loudspeakers prefer a live front wall to a dead front wall. By these terms we mean the amount of reflection of

~ÄëçäìíÉ=ÑáÇÉäáíó™ Mastering the Refinements of the system Fine tuning an audio system is an art that will take time and patience. It can be one of the more rewarding learning experiences you will have in the pursuit of music and its enjoyment. One of the best pieces of advice we can offer is that you take advantage of the ear's ability to identify similarities in sound. This ability is useful in fine tuning your system because if every recording you listen to has a similarity of soun

~ÄëçäìíÉ=ÑáÇÉäáíó™ The Technology The Genesis Ribbon Tweeter Reviewers in the Audiophile press have often remarked that the Genesis circular ribbon tweeter is the world’s best. It is a one inch circular planar ribbon design crafted from an extremely thin membrane of Kapton with a photo-etched aluminium “voice coil” that is a mere 0.0005 inch thick. The entire radiating structure has less mass than the air in front of it! That is why it will reproduce accurately frequencies beyond 36k

~ÄëçäìíÉ=ÑáÇÉäáíó™ The driver is housed in an enclosure that is open to the back. Thus, the midrange operates as a dipole too. Mid-Bass Couplers In order to create a “sound bridge” between the midrange and the bass section, the G5.2 incorporates two 6.5inch metal cone mid- bass couplers. One front and one rear firing, again working as a dipole. Made of aluminum, this metal cone is extremely light and stiff. The driver is hence capable of handling the huge dynamic range demands of the

~ÄëçäìíÉ=ÑáÇÉäáíó™ When the signal stops, it detects that the woofer will continue to move when it shouldn’t 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 seem massless. Typical non-servo woofer systems have distortion levels that exceed 10% at even moderate levels. The Genesis servo bass system reduces this dist

~ÄëçäìíÉ=ÑáÇÉäáíó™ driver is a perfect piston within the frequencies used. Thus, low cone break-up distortion is inherent in the driver designed for the G5.2. Unlike the mid-bass couplers, midrange and the tweeters, which operate in dipole, the three woofers in the G5.2 operate in phase as an omni-pole. All three woofers work in phase to control the air mass of the listening room. This means that the surface area of the three cones and the loudspeaker enclosure all work in unison to pr
