3 Installation in Brief 3 I NST ALLA TION IN B RIEF W e know you are eager to hear your Script loudspeakers, so this section is provided to allow fast and easy set up. Once you have them operational, please take the time to read, in depth, the rest of the information in this manual.
4 Introduction I NTRODUCTION Congratulations! Y ou have invested in one of the world’s premier loudspeak er systems. The MartinLogan Script represents the culmination of an intensive, dedicated grou.
O PERA TION Operation 5 Because your Scripts use an internal power supply to ener- gize their electrostatic cells with high-voltage DC, they must be connected to an AC power source. F or this reason they are provided with the proper IEC standard power cords.
Unpack the Script speakers with brackets attached and the accessory kit. Y ou should find: 2 ea. - Script speaker with bracket 4 ea. - wall anchors 4 ea. - #8 x 1 inch Phillips head screw 4 ea. - #12 black flat washers 4 ea. - 5/8 inch fiber washers 2 ea.
Mounting the Script 7 1 Mark a center point on the wall where you want to mount the Script, 38 inches above the floor . This point is the height recommended by MartinLogan to mount the Script wall bracket and will be the location into which the wall brackets upper mounting wall anchor and screw are driven.
8 Mounting the Script 5 Move the wall bracket back into position over the wall anchor and place #12 metal washer on one of the screws and drive it through the slot at the bottom-back of the bracket into the mounting anchor . Do not tighten (see figure 5).
Mounting the Script 9 8 P osition a black rubber spacer over the threaded hole in the top of the speaker cabinet and carefully pivot the top of the Script into the wall bracket. Carefully move the speaker cabinet so that the center of the rubber spacer , the top-support hole, and the threaded hole on top of the Script cabinet are aligned.
10 Room Acoustics 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. Y our room is actually a component and an important part of your system.
Room Acoustics 11 Hard vs. Soft Sur faces If the front or back wall of your listening room is soft, it might benefit you to have a hard or reflective wall in opposition. The ceiling and floor should follow the same basic guideline as well. However , the side walls should be roughly the same in order to deliver a focused image.
12 Dispersion Interactions Y our Scripts launch a 30 degree dispersion pattern when viewed from above. This horizontal dispersion field gives a choice of good seats for the performance while minimizing interactions with side walls (See F igure 9).
Dispersion Interactions 13 Figure 11–12. As can be seen here, point source concepts invite a great deal of room interaction. While delivering good frequency response to a large listening audience, imaging is consequently confused and blurred. Figure 13 –14.
It had long been the practice of stereo buffs to connect their television to the stereo system. The advantage was the use of the larger speakers and more powerful amplifier of the stereo system. Even though the sound was greatly improved, i t was still mono and limited by the broadcast signal.
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, diap.
ESL P anel Critical Zone: 500Hz–20kHz 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 Script uses no crossover networks above 500 Hz because they are not needed.
Since the beginning of audio, achieving smooth dispersion has been a problem for all loudspeaker designers. Large panel transducers present even more of a challenge because the larger the panel, the more directional the dispersion pattern becomes.
18 Electrostatic Loudspeaker History In the late 1800s, any loudspeaker was considered exotic. T oday , 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.
Electrostatic Loudspeaker History 19 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.
20 Frequently Asked Questions F REQUENTL Y A SKED Q UESTIONS How do I clean my speak ers? Just use a dust free cloth or a soft brush to remove the dust from your speakers. W e recommend a specialty cloth (available through the XStatic shop at www .martinlogan.
Frequently Asked Questions 21 Will excessive smok e or dust cause any problems with my electrostatic speak ers? Exposure to excessive contaminants such as smoke or dust may potentially affect the performance of the electrostatic membrane, and may cause discoloration of the diaphragm membrane.
22 Troubleshooting T ROUBLESHOOTING No Output •Check that all your system components are turned on. •Check your speaker wires and connections. •Check all interconnecting cables. W eak Output, Loss of Highs •Check that the power cord is properly connected.
23 The Script hybrid speaker system consists of a broad-range single element electrostatic transducer integrated with a quick-response woofer . This approach takes advantage of the benefits that both technologies have to offer . Dispersion is a controlled 30 degrees.
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.
25 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 i s measured in henrys. Inductor . A device designed primarily to introduce inductance into an electrical circuit.
