Page 3: Installation In Brief
Clarity speakers, please refer to the Room Acoustics, Placement or Operation sections of this manual. Should you encounter a persistent problem that cannot be resolved, please contact your local authorized MartinLogan dealer. They will provide you with the appropriate techni- cal analysis to alleviate the situation. -
Page 4: Operation
Substantially impaired performance or severe damage may occur to a Clarity speaker if opera- tion is attempted from an incorrect AC power source. WARNING! The DC power supply should not be installed, removed, or left detached from the speak- er while connected to an AC power source. -

NAC’s perforated screen (see figure 2). For more information on the NAC see the ‘MartinLogan Exclusives’ section (page 15) and the ‘Dispersion Interactions’ section of this manual (page 10). -
Page 6: Placement
In long rooms, naturally, that relationship changes. The distance between the speakers will be far less than the distance from you to the speaker system. However, in a wide room, you will still find that if... -
Page 7: Final Placement
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. The size of the instruments should be neither too large nor too small. -
Page 8: Room Acoustics
Reflective Surfaces (near-field reflections) The hard surfaces of your room, particularly if close to your speaker system, will reflect some waves back into the room over and over again, confusing the clarity and imaging of your system. The smaller sound waves are mostly affected here, and occur in the mid and high frequencies. -

After living and experimenting with your Clarity’s, you may want to use Clarity ETC (energy transfer coupler) Spikes (see figure 4), which are available from your local MartinLogan dealer or from the Xtatic shop at www.martinlogan.com. With the use of these spikes, the Clarity will become more firmly planted on the floor and, consequently, bass will tight- en and imaging will become more coherent and detailed. -
Page 10: Dispersion Interactions
Each Clarity is a 26” inch line source beginning 25" inches above the base. Figure5. MartinLogan Clarity’s deliver a 30 degree wave launch dispersion pattern distributed horizontally. Figure 7. Horizontal dispersion effects of the NAC driver. -
Page 11: Three Major Types Of Dispersion
By curving the radiating surface, we create the effect of a horizontal arc. This allows the engineers at MartinLogan to control the high frequency dispersion pattern of our transducers. That is why you see the gentle curve on our products. -
Page 12: Home Theater
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 sepa- rately. -
Page 13: Electrostatic Advantages
Since the diaphragm of an electrostatic speaker is uniformly driven over its entire area, it can be extremely light and flexible. This allows it to be very responsive to transients, thus perfectly tracing the music signal. -
Page 14: Full Range Operation
Full Range Operation The most significant advantage of MartinLogan’s exclusive transducer technology reveals itself when you look at exam- ples of other loudspeaker products on the market today. The Clarity uses no crossover networks above 450 Hz because they are not needed. The Clarity consists of a single, seamless electrostatic membrane reproducing all frequencies above 450 Hz simultaneously. -

As a result, no discharging or “arcing” occurs. Transducer Integrity All MartinLogan transducers begin with two pieces of high- grade, cold rolled steel. These steel pieces are then custom perforated and insulated with a unique composite coating. -

“exotic”. Bell Laboratory’s electrostat was something to behold. This enormous bipolar speaker was as big as a door. The diaphragm, which was beginning to rot, was made of a pig intestine that was covered with fine gold leaf to con- duct the audio signal. - Page 17 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. Janszen believed that electrostats were inherently more linear than cones, so he built a model using a thin plastic diaphragm treated with a conductive coating.

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.

• Check placement. Are both speakers the same distance from the walls? Do they have the same amount of toe- in? Try moving the speakers away from the back and sidewalls. • Check the polarity of the speaker wires. Are they con- nected properly? -

If this is the case, please contact your authorized MartinLogan dealer. Service Should you be using your MartinLogan product in a country other than the one in which it was originally purchased, we ask that you note the following:... -

Impedance. The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker’s impedance changes with frequency, it is not a constant value. - Page 23 Sensitivity. The volume of sound delivered for a given elec- trical input. Stator. The fixed part forming the reference for the moving diaphragm in a planar speaker. THD. The abbreviation for total harmonic distortion. (See Distortion) TIM. The abbreviation for transient intermodulation distortion.
