Introduction Thank you—the MartinLogan owner, for loving what we do, and making it possible for us to do what we love. Congratulations! You have invested in one of the world's premier subwoofers. The MartinLogan Dynamo 700 represents the extension of an intensive, dedicated team research program directed toward establishing a world class line of reference subwoofers using leading-edge technology, without compromising durability, reliability, craftsmanship or aesthetics.
Installation in Brief We know that you are eager to hear your new Dynamo 700 subwoofer, 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. It will give you perspective on how to attain the greatest possible performance from this most exacting subwoofer system. Placement section (page 11) of this manual for more details. Step 3: Signal Connection Use the best cables you can.
About the Controls Figure 1. Dynamo 700 controls. Level Knob Setting the level too high will cause the bass to seem bloated and is the single most common cause of bad sounding subwoofers. A rule of thumb is that the subwoofer should not draw attention to itself, but should simply make the systems low end seem more extended and accurate.
Connections and Control Settings Before Connecting the Dynamo MartinLogan's engineering and design team developed the Dynamo 700 for easy setup and system integration. Before beginning to connect your Dynamo 700, please review the controls discussed in the last section. An understanding of these will help speed you along as you connect and integrate your Dynamo 700 with your system. All signal connections are done on the rear connections panel of the Dynamo 700.
Multi-Channel/LFE Mode This setup is recommended if your Dynamo 700 will be used in a dedicated home theater or multi-channel system. When a signal is connected to the subwoofer’s LFE input, and the crossover switch is set to 'Bypass (LFE In)' the internal low pass filter is not active. By following this setup, you will allow your processor to handle most of the bass management.
AC Power Connection WARNING! The power cord should not be installed, removed, or left detached from the subwoofer while the other end is connected to an AC power source. The IEC power cord should be firmly inserted into the AC power receptacle on the rear connection panel of the Dynamo, then to any convenient AC wall outlet.
Placement Listening Position Generally, subwoofers have the most output when placed in the corner of a room. However, this can also exaggerate the subwoofers output making blending difficult. We recommend starting by placing the Dynamo 700 in a corner. If, after the full range of tuning techniques have been employed, the subwoofer sounds like it has too much upper bass energy try pulling it away from the wall, toward the listening position.
Figure 9. The Dynamo 700 is capable of both front-firing and down-firing woofer orientations. Changing Woofer Orientation When installing the Dynamo 700 in a cabinet it is recommended that the subwoofer be converted to a front firing configuration. (see figure 9). 1 Prepare a flat surface with a blanket to protect the Dynamo 700's finish. Unplug signal and power connections. Remove the grill cloth. 2 Carefully lay the Dynamo 700 on its side. Using a coin, unscrew the attached feet. (see figure 10).
Room Acoustics Your Room This is an area that requires both a little background to understand and some time and experimentation to attain the best performance from your system. Your room is actually a component and an important part of your system. This component is a large variable and can dramatically add to or subtract from a great sonic experience. All sound is composed of waves.
Home Theater 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. In the late 1970’s and early 1980’s two new home movie formats became widely available to the public: VCR and laser disc. By 1985, both formats had developed into very high quality audio/video sources.
Frequently Asked Questions & Troubleshooting Frequently Asked Questions Troubleshooting How do I clean my subwoofer? Use a dust free cloth or a soft brush to clean your subwoofer. We recommend a specialty cloth (available through the Xtatic shop at www.martinlogan.com) that cleans better than anything else we have tried. No Output • Check that all your system components are turned on. • Check that the master power switch adjacent to the AC receptacle is set to 'Auto On'.
General Information Specifications The Dynamo 700 subwoofer system consists of a single woofer for high SPL output with minimal distortion. The equalization used is specifically designed to counteract the response of the woofers sealed box response. This equalization leads to minimal group delay and proper transient response. Warranty and Registration Your Dynamo 700 subwoofer is provided with an automatic Limited 90 Day Warranty coverage. System Frequency Response 24–200 Hz ± 3 dB. Anechoic in LFE mode.

Glossary of Audio Terms AC. Abbreviation for alternating current. DC. Abbreviation for direct current. Active crossover. Uses active devices (transistors, ICs, tubes) and some form of power supply to operate. Diffraction. The breaking up of a sound wave caused by some type of mechanical interference such as a cabinet edge, grill frame or other similar object. Amplitude. The extreme range of a signal. Usually measured from the average to the extreme. Arc.
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. Sometimes called a choke or coil. Linearity. The extent to which any signal handling process is accomplished without amplitude distortion. Midrange. The middle frequencies where the ear is the most sensitive.
WARNING! Do not use your Dynamo 700 loudspeakers outside of the country of original sale—voltage requirements vary by country. Improper voltage can cause damage that will be potentially expensive to repair. The Dynamo 700 is shipped to authorized MartinLogan distributors with the correct power supply for use in the country of intended sale.
