Installation in Brief 3 I NST ALLA TION IN B RIEF W e know you are eager to hear your new Cinema i 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.
Y our Cinema i speaker uses an external low-voltage power supply to energize its electrostatic panel. F or this reason the proper low-voltage power supply is provided. The power supply should be firmly inserted into the ‘P ower In ’ receptacle on the rear connection panel of the speaker , then to any convenient AC wall outlet (see figure 1).
W e also recommend, if possible, that short runs of speaker cable connect the power amplifier and speaker and that high quality long interconnect cables be used to connect the preamplifier and power amplifier .
6 Installation F or optimum performance the Cinema i must be tilted on its stand towards the main listening position and directed towards the audience’s ears (see figure 4). After you have placed your Cinema i in its final location, support the speaker with one hand and slightly loosen the large knobs with the other hand.
Stand Options 7 NOTE: The Cinema i is intended for use with its stand attached in almost all installation options. Stand removal instructions are provided in case you are using a custom installation that does not require the use of the stand.
8 Stand Options 1 Prepare a flat surface with padding and sheets to protect the Cinema i as you work on it. Disconnect any wires and carefully place the Cinema i upside down on the work surface, using books or pieces of cardboard to keep the speaker from rocking .
3 Using a 5 / 32 ” Allen tool remove the 6 allen bolts that attach the stand, 3 each side (figure 7, step B). 4 Remove the stand (figure 7, step C). 5 Unscrew the two large knobs and remove the center part of the stand. Set the 2 bolts, 2 rubber washers, 2 plastic washers and the large knobs nearby (figure 8, step D).
10 Remove the Cinema i stand from the wall and prepare the wall at each of the 5 marks using the procedure described in step 7 (figure 12, step I). 11 With the help of an assistant, place the center part of the stand against the wall and attach it using the (6) 1 “ Phillips head screws.
Dispersion Interactions 11 The concave electrostatic panel launches a 30 degree dispersion pattern when viewed from above. The sound waves focus in front of the speaker and diverge much like a lens would cause light to focus and diverge.
12 Dispersion Interactions Figure 18–19. 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 20– 21.

Ascent i speakers as front channels, Cinema i as the center channel, Script i speakers as side surround (effects) channels, and Depth subwoofers as 0.1 (effects) channel. It had long been the practice of stereo buffs to connect their television to a stereo system.
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.
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 dis- persion pattern becomes.
16 Electrostatic Loudspeaker History E LECTROST A TIC L OUDSPEAKER H ISTORY 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.
Electrostatic Loudspeaker History 17 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.
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 at the Xtatic 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 turned on. • Check your speaker wires and connections. • Check all interconnecting cables. W eak Output from Electrostatic P anel, Loss of Highs • Check the power cord.
The Cinema i 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 is measured in henrys. Inductor . A device designed primarily to introduce inductance into an electrical circuit.
