MartinLogan Source Speakers - Manual

6 Connections C ONNECTIONS Low-Voltage (DC) Power Connection Your Source speakers use external low-voltage power sup-plies to energize their electrostatic panels. For this reason the proper low-voltage power supplies are provided. A power supply should be firmly inserted into the ‘DC Power In’ recep...

Connections 7 Speaker Level Connection Use the best speaker cables you can. The length and type of speaker cable used in your system will have an audible effect. Under no circumstance should a wire of gauge higher (thinner) than #16 be used. In general, the longer the length used, the greater the ne...

8 Placement & Room Acoustics Your speakers should be placed approximately two to three feet from the front wall, the wall in front of the lis-tening position, and about two feet from the side walls. Your sitting distance should be further than the distancebetween the speakers themselves. You are...

Placement & Room Acoustics 9 Tilting the Speakers Backwards and Forwards As the diagrams show in the Dispersion Interactions sec-tion of this manual (page 12), the vertical dispersion is directional above and below the stator panel itself. In some instances, if you are sitting close to the floor...

10 Placement & Room Acoustics your speaker slightly forward into the room. What hap-pened to the bass response? What happened to the imaging? If the imaging is more open and spacious and the bass response is tightened, that is a superior posi-tion. Move the speakers back six inches from the init...

Placement & Room Acoustics 11 Clap your hands. Can you hear an instant echo respond back? You have near-field reflections. Stomp your foot. Can you hear a “boom”? You have standing waves or large panel resonances such as a poorly supported wall. Put your head in a small cavity area and talk loud...

12 Dispersion Interactions D ISPERSION I NTERACTIONS Your Source’s launch a 30 degree horizontal dispersion pat-tern. This horizontal dispersion field gives a choice of good seats for the performance while minimizing interactions with side walls (see figure 7). Make sure both speakers stand exactly ...

Home Theater 13 It had long been the practice of stereo buffs to connect their television to a 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, it was still mono and limited by the broadcast ...

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 deals with cones, domes, diaphragms and ribbons that are moved with magnetism, the world of electrost...

MartinLogan Exclusives 15 Another significant advantage of MartinLogan’s exclusivetransducer technology reveals itself when you look at exam-ples of other loudspeaker products on the market today. The Source uses no crossover networks above 470 Hz because they are not needed. The Source consists of ...

16 MartinLogan Exclusives CLS™ (Curvilinear Line Source) Since the beginning of audio, achieving smooth dispersion has been a problem for all designers. Large panel trans-ducers present unique challenge because the larger the panel, the more directional the dispersion pattern becomes. Wide range ele...

How do I clean my speakers? Use a dust free cloth or a soft brush to remove the dust from your speakers. We also recommend a specialty cloth (available at the Xtatic shop at www.martinlogan.com) that cleans your speakers better than anything else we have tried. For the wood surfaces it is acceptable...

Will excessive smoke or dust cause any prob-lems with my electrostatic speakers? Exposure to excessive contaminants such as smokeor dust may potentially affect the performance of the electrostatic membrane, and may cause discolorationof the diaphragm membrane. When not in use for extended periods, y...

No Output • Check that all your system components are turned on.• Check your speaker wires and connections.• Check all interconnecting cables.• Try hooking up a different set of speakers. The lack of output could point to a problem with other equipment in your system (amp, pre-amp, processor, etc.) ...
