Installation in Brief 3 I NST ALLA TION IN B RIEF W e know you are eager to hear your new Theater center channel, so this section is provided to allow fast and easy set up. Once you have it 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 a new world of home theater! The MartinLogan Theater represents the culmination of an intensive, dedicated group research program di.
Because your MartinLogan Theater uses an internal power supply to energize its electrostatic cells with high-voltage DC, it must be connected to an AC power source.
6 Installation F or optimum performance the Theater must be tilted on its stand towards the main listening position and directed towards the audiences ears (see figure 3).
Stand Removal and Installation 7 NOTE: The Theater is intended to be used with its stand attached in almost all installation options. Stand Removal and Installation instructions are provided in case you are using a custom installation that does not require the use of the stand.
8 Mounting the Theater On A Wall M OUNTING THE T HEA TER O N A W ALL WARNING! Installing the Theater on the wall requires 2 people. Do not try this alone. Mounting the Theater on a wall requires a mini- mum use of 1 lag bolt sunk directly into a stud and 2 wall anchors.
Mounting the Theater On A Wall 9 Figure 7. Hardware included with the Theater . Figure 8. The Theater mounted in various stud configurations. F ront View . Please note, to simplify this illustration, the stand is shown without the Theater attached. When mounting the Theater , the stand should not be removed .
10 Mounting the Theater On A Wall 4. Using a level, vertically measure down from point B 4 1 / 16 inches (10.3 cm) and mark this point (point E, see figure 9).
Dispersion Interactions 11 The convex electrostatic panel launches a 30 degree dis- persion pattern when viewed from above. This horizontal dispersion field gives you a choice of good seats for the performance while minimizing interaction with side walls (see figure 10).
ó12 Dispersion Interactions Figure 12– 13. 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 14– 15.
H OME T HEA TER Home Theater 13 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.
14 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 d.
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.
16 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 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.
18 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 19 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.
20 Troubleshooting T ROUBLESHOOTING No Output •Check that all your system components are powered on. •Check your speaker wires and connections. •Check all interconnecting cables.
The Theater 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.
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.
