~ÄëçäìíÉ=ÑáÇÉäáíó A Message from Genesis Congratulations! You are now the owner of the finest loudspeaker system in the world. The Genesis Advanced Technologies 1.1 Loudspeaker System is the embodiment of our philosophy of “absolute fidelity” – the ability to reproduce any musical event faithfully, with no compromise, in your home. With its vast abilities, the Genesis 1.1 is also able to deliver sound as the filmmaker intended in home theater applications. The Genesis 1.1 is commi

~ÄëçäìíÉ=ÑáÇÉäáíó Micro Dynamic Capability: This describes the ability of a system to resolve the lowest level material with as much articulation and imaging as it does at the louder levels. The most difficult areas for loudspeaker systems to reproduce well are the extremes, i.e. the micro-dynamics from ppp to p (pianissimo to piano), and the last part of the macro- dynamics f to fff (forte to triple forte). Imaging and Soundstaging: A reference system must be able to recreate a deep

~ÄëçäìíÉ=ÑáÇÉäáíó 1 Set-up Guide Now that you have your new Genesis 1.1 loudspeaker system, we realize that you can’t wait to hook it up and start playing! However, this is a big, complex system. There is no “quick” set-up. You will need at least three immensely strong people. Be prepared to allocate 5 to 8 hours to the initial unpacking, set-up and configuration. Mentally condition yourself for hard, manual work that must also be done carefully and precisely so as not to hurt your

Verify that the positions are accurately aligned as it may be impossible to move them later. Next, remove the woofer towers from their shipping crates. These are the largest of the wooden crates. Position the crate near where you have put the woofer tower bases. You do not want to move the woofer tower very far once it

The wings are marked left and right, so set them up on the correct side. First locate the crate containing the left wings, and locate the corresponding Corian panel. The left Corian panel will have the column of tweeters to the right of the midrange ribbon. Unscrew the top of crates and remove the lids. First, remove the Cori

~ÄëçäìíÉ=ÑáÇÉäáíó 1.2 Placement of the Genesis 1.1 Loudspeaker The G1.1 requires a large room in order to give the speaker ample space from the walls so that it can perform at its best. A typical room size is 29 ft x 48 ft with 12 ft ceilings. A good starting position for the midrange/tweeter panels is 15 feet into the room as measured from the front wall (the wall behind the speakers which you look at as you are seated listening to the speakers) to the face of the speakers. You wi

~ÄëçäìíÉ=ÑáÇÉäáíó For some rooms, there may not be enough space and you will have to adjust as you see fit. In a smaller room, the speakers can be just 20% of the way into the room, and the listening position can then be 20% from the rear wall. (see the diagram above). If you have to sit less than 10 feet in front of the speakers, you have too small a room to accommodate the Genesis 1.1’s. 1.3 Woofer Connections Included with your Genesis 1.1 is a set of four large cables (with 3

Otherwise, the ground jack can just be left unplugged. 1.4 Servo-controlled Bass Amplifier Connections The way that the Servo Controlled Bass (SCB) amplifier is connected to the rest of your system will largely determine the coherency of the bass to the midrange. However, no one method will work with all systems. The first big problem is that no power amplifier is “straight wire with gain”. The se

~ÄëçäìíÉ=ÑáÇÉäáíó The preferred connection is to attach the bare wire on the Servo-Bass Interconnect to the midrange INPUT binding posts on the crossover box. This way, the Servo-Bass amplifier will “see” the same musical signal as the midrange/tweeter crossover, resulting in the most coherent crossover between the upper bass and lower midrange. We prefer the second method. This will allow everything in the chain up to the Genesis 1.1 crossover box (including all electronics and ca

~ÄëçäìíÉ=ÑáÇÉäáíó use the supplied jumpers to connect the rear tweeters either to the midrange or the front tweeters. Depending on the amplifier used, one or the other will sound better. These jumpers are made using the same internal wire connect the drivers of the Genesis 1.1. However, you should also try using jumpers made of the same wire as you use for your speaker cables. For example, if your speaker cables are Cardas Golden Reference, then get the same for your jumpers. Next,

If your power amplifier is a transformer-coupled valve design, adjust the phase to 75. The remote control has two buttons on the lower portion of the hand- held marked “MEM 1” and “MEM 2”. These controls will memorize the settings you have selected. To memorize a setting, point the remote control at the amplifier. Press the MEM1 or ME

~ÄëçäìíÉ=ÑáÇÉäáíó 2.1 Begin with the bass level For now, leave the low-pass filter set at 100 Hz, This control will be addressed later. Turn the volume 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 blend. The voice and the music ac

~ÄëçäìíÉ=ÑáÇÉäáíó 2.2 Imaging and Soundstage One great advantage of a true line-source is that good imaging and soundstage is a given. However, it is possible to fine-tune the system for ultimate enjoyment. If your vocal selection is a well-recorded audiophile CD or LP with good soundstaging information, the performer should appear to come from behind the loudspeakers and be at the appropriate height for a standing person. If the vocal appears to be larger than life, you should fir

~ÄëçäìíÉ=ÑáÇÉäáíó 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 there should be tremendous front to back depth. When the recording is close-miked (when the instrument or performer is very close to the recording microphone), the music may appear to come directly from the loudspeaker. This is normal. Typically, however, the sound should appear to

~ÄëçäìíÉ=ÑáÇÉäáíó 2.4 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 some problematic rooms a resonance may develop at one or two frequencies that is unnatural to the music. By moving the woofer towers closer to the rear wall or

~ÄëçäìíÉ=ÑáÇÉäáíó 3.3 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. If you find that the sound is not spacious enough or you are not getting enough front to back depth, pull the speaker away fro

~ÄëçäìíÉ=ÑáÇÉäáíó the mid-bass regions. Keep the low-pass below 115Hz except in exceptionally large rooms. Another good rule of thumb is to first set the volume control of the woofer towers for proper mid-bass rather than low bass. The theory is that if the mid-bass is correct, then the low bass should be very close to correct. If the mid-bass is proper and the low bass is still not right, here are some other suggestions: A good balance between proper low bass extension and a deep a

However, as a rule of thumb, it is a good idea to keep the speaker as far away from the sidewalls as is practical. With this in mind, it may be helpful to add some damping material or diffuser panels to the point of first reflection. This is where the sound from the loudspeaker first hits the sidewall, then bounces to the listener. This reflection is undesirable because it is s
