4 Contents C ONTENTS WARNING! Do not use your Stage loudspeaker outside of the country of original sale—voltage requirements vary by country. Improper voltage can cause damage that will be potentially expensive to repair.
Installation in Brief 5 We know you are eager to hear your new MartinLogan loudspeaker, so this section is provided to allow fast and easy set up. Once your new speaker is operational, please take the time to read, in depth, the rest of the informa- tion in the enclosed manual.
6 Introduction Congratulations! You have invested in one of the world’s premier loudspeaker systems. The Stage represents an advanced combination of sonic technologies establishing an unprecedented direction for audiophile design.
Connections 7 C ONNECTIONS AC Power Connection Your Stage uses an external low-voltage power supply to energize its electrostatic panel. For this reason the proper low-voltage power supply is provided.
Using Only One Power Supply You may have noticed a connection on the back of your Stage labeled ‘Power Out’. The use of this connec- tion will allow you to daisy-chain up to five low-voltage MartinLogan products and eliminate the need for multiple low-voltage power supplies.
Installation 9 I NST ALLA TION For optimum performance the Stage must be tilted on its stand towards the main listening position and directed towards the audience’s ears (see figure 3).
10 Installation Mounting the Stage On A W all NOTE: These instructions describe how to remove the stand from the Stage and mount it to the wall. MartinLogan rec- ommends using 4 wall anchors and machine screws to secure the Stage bracket to the wall.
4 Place the bracket against the wall at the desired location. It is important that the entire area behind the bracket, and 8.5 inches to the left and right of the bracket be free from obstructions and completely flat.

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 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.
MartinLogan Exclusives 15 XStat™ Transducer XStat™ transducers incorporate a myriad of technology and design innovations including CLS™, MicroPerf, Generation 2 Diaphragms, ClearSpars™, and Vacuum Bonding. CLS™ (Curvilinear Line Source) Since the beginning of audio, achieving smooth dispersion has been a problem for all designers.
16 Electrostatic History In the late 1800’s, any loudspeaker was considered exotic. Today, 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 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 How do I clean my speaker? Use a dust free cloth or a soft brush to remove the dust from your speaker. We also recommend a specialty cloth (available at the Xtatic shop at www.martinlogan. com) that cleans your speaker better than anything else we have tried.
Frequently Asked Questions 19 Will excessive smoke or dust cause any problems with my electrostatic speakers? 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 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 speaker. The lack of output could point to a problem with other equipment in your system (amp, pre-amp, processor, etc.
