Page 3: Installation In Brief
Step 3: Power Connection (AC) (see warning) MartinLogan speakers require AC power to energize their electrostatic cells. Using the AC power cords provided, plug them in first to the AC power receptacle on the rear panel of the speaker, making sure that you have made a firm connection, and then to the wall outlet. -
Page 4: Introduction
NTRODUCTION Congratulations! You have invested in one of the world’s premier loudspeaker systems. The MartinLogan Scenario represents the culmination of an intensive, dedicated group research program directed toward establishing a world class reference monitor utilizing leading-edge technology, without compromising durability, reliability, craftsmanship or aesthetic design. -
Page 5: Operation
AC Power Connection Because your MartinLogan Scenario’s use an internal power supply to energize their electrostatic cells with high-voltage DC, they must be connected to an AC power source. For this reason they are provided with the proper IEC standard power cords. -
Page 6: Placement
LACEMENT Listening Position By now your speakers should be placed approximately two to three feet from the front wall, the wall in front of the listening position, and at least one to two feet from the side walls. Your sitting distance should be further than the distance between the speakers themselves. -
Page 7: Final Placement
Imaging In their final location, your Scenario’s should have a stage width somewhat wider than the speakers themselves. On well recorded music, the instruments should extend beyond the edges of each speaker to the left and to the right, yet a vocalist should appear directly in the middle. -

COUSTICS Your Room This is one of those areas that requires both a little back- ground to understand and some time and experimentation to attain the best performance from your system. Your room is actually a component and an important part of your system. -

23” inch line source beginning 22" inches above the floor level (See Figure 7). This vertical dispersion profile minimizes interactions with the floor and the ceiling. Figure 6. MartinLogan Scenario’s deliver a 30 degree wave launch dispersion pattern distributed horizontally. Dispersion Interactions... - Page 11 Figure 11–12. A controlled 30-degree cylindrical wave-front, which is a MartinLogan exclusive, offers optimal sound distribution with minimal room interaction. The result is solid imaging with a wide listening area.

Home theater is a complex purchase and we recommend that you consult your local MartinLogan dealer as they are well versed in this subject Each piece of a surround system can be purchased separately. -
Page 13: Electrostatic Advantages
How can sound be reproduced by something that you are able to see through? Electrostatic energy makes this possible. Where the world of traditional loudspeaker technology deals with cones, domes, diaphragms and ribbons that are moved with magnetism, the world of electrostatic loudspeakers deals with charged electrons attracting and repelling each other. -
Page 14: Full Range Operation
Full Range Operation The most significant advantage of MartinLogan’s exclusive transducer technology reveals itself when you look at examples of other loudspeaker products on the market today. The Scenario uses no crossover networks above 500 Hz because they are not needed. The Scenario consists of a single, seamless electrostatic membrane reproducing all fre- quencies above 500 Hz simultaneously. -

After creating this technology, MartinLogan developed the production capability to bring it out of the laboratory and into the market place. You will find this proprietary MartinLogan technology used in all of our products. -
Page 16: Electrostatic Loudspeaker History
LECTROSTATIC OUDSPEAKER In the late 1800s, any loudspeaker was considered exotic. Today, most of us take the wonders of sound reproduction for granted. It was 1880 before Thomas Edison had invented the first phonograph. This was a horn-loaded diaphragm that was excited by a playback stylus. - Page 17 In 1947, Arthur Janszen, a young Naval engineer, took part in a research project for the Navy. The Navy was interested in developing a better instrument for testing microphone arrays. The test instrument needed an extremely accurate speaker, but Janszen found that the cone speakers of the period were too nonlinear in phase and amplitude response to meet his criteria.

2 Ohms. Could you suggest a list of suitable electronics and cables that would be ideal for MartinLogan speakers? The area of electronics and cable choice is probably the most common type of question that we receive. It is also the most subjective. - Page 19 How do MartinLogan speakers hold up over a long term in the humidity of tropical climates? We should tell you that MartinLogan indeed has a very substantial number of customers in tropical regions of the world.

LOSSARY OF UDIO AC. Abbreviation for alternating current. Active crossover. Uses active devices (transistors, ICs, tubes) and some form of power supply to operate. Amplitude. The extreme range of a signal. Usually measured from the average to the extreme. Arc. The visible sparks generated by an electrical discharge. Bass. - Page 23 Inductance. The property of an electrical circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys. Inductor. A device designed primarily to introduce inductance into an electrical circuit.
