  • Page 3: Installation In Brief

    Please see the Installation section (page 6) of this manual for more details. Step 3: Power Connection (AC) (see warning) MartinLogan speakers require AC power to energize their electrostatic cells. Using the AC power cords provided, plug the Theater in first to the AC power receptacle on the rear panel of the speaker, making sure that you have made a firm connection, and then to the wall outlet.

  • Page 4: Introduction

    NTRODUCTION Congratulations! You have invested in a new world of home theater! The MartinLogan Theater represents the culmination of an intensive, dedicated group research program directed toward establishing a world class reference monitor utilizing leading-edge technology, without compromising durability, reliability, craftsmanship or aesthetic design.

  • Page 5: Operation

    AC Power Connection 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. For this reason it is provided with the proper IEC standard power cord.

  • Page 6: Installation

    WARNING! Installation other than that described in the body of this document requires specific documentation from MartinLogan. Installation Rubber Bumper Feet If you are using the Theater on top of your television, or setting it on any type of surface, we recommend installing the 5 rubber bumper feet included with the Theater.

    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.

    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 separately.

  • Page 14: 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.

    This is also why you see the unique “see through” cylindrical shape of all MartinLogan products. 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.

    However, Lodge had no intention for his device to reproduce music because in 1898 there was no way to amplify an electrical signal! As a result, his speaker had nothing to offer over the acoustical gramophones of the period. It was not until 1906 that Dr. Lee DeForrest invented the triode vacuum tube.

    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.

The abbreviation for total harmonic distortion. (See Distortion.) TIM. The abbreviation for transient intermodulation distortion.
