Your purchase of the Daniel Hertz M1 speaker is just the beginning of a long relationship. We are at your service.

The luxurious edimoe wood finish is less costly than the piano black used on the M1, M2, and M3 speakers. Thus the M7 provides Daniel Hertz speaker quality of sound and construction in the most affordable version. Discreet and elegant, the Daniel Hertz M7 is designed to be used as a full range speker in applications where the most powerful bass is not required.

3 Overview Daniel Hertz puts you, our customer, first. Our philosophy is based on quality, simplicity, science and the human heart. Daniel Hertz components can be used separately with other audio equipment, but are optimized to work together as complete systems. The sonic result is carefully tuned to perfection. This level of performance cannot be obtained by accident, i.e. mixing and matching components. The system approach produces the most natural sound, extreme ease of operation, and the highest reliability. Our classical design which is always pleasing to the eye. Daniel Hertz engineers and craftspeople fine-tune the sonic quality of each component with science and the ear. With Daniel Hertz systems, you hear the beginnings of notes, the full body of the sound, the details and harmonics and the most subtle sounds, so you have real connection with what the musicians are doing, and you experience what they intend. The full potential of the Daniel Hertz M7 is obtained with the Daniel Hertz M5 Telikos Mono Reference Power Amplifier, designed with high purity in the milliwatt region; the Daniel Hertz M6 1 MegOhms Preamplifier, a new design with ultratransparent sound; the Daniel Hertz Silver 1 pure silver litz interconnects; and Daniel Hertz Premium 500 speaker cable. Daniel Hertz is the most advanced audio achievement personally designed by Mark Levinson. Until now, people had to choose between systems that had pleasing sound but lacked vitality, or systems with more vitality but lacking natural sound. A new series of high efficiency speaker drivers is the foundation of Daniel Hertz systems. It is essential to understand why high efficiency is important. The laws of physics say that the lower the efficiency of a speaker, the more music is turned into heat. Whatever is turned into heat is lost. You cannot get it back with more powerful amplifiers. With Daniel Hertz systems, 1 Watt of power produces 100 decibels (db) of sound pressure level (SPL). This means that most listening levels require only milliwatts of power. 4 5

4 Product Description The Daniel Hertz M7 is a 2 way speaker design using a high frequency compression driver and a 12 woofer. Two channels of power amplification are required for operation. We recommend two Daniel Hertz M5 Telikos Mono Reference Power Amplifiers, each mono amplifier driving one M2 speaker, with the Daniel Hertz M6 1 MegOhms Preamplifier as the front end. The sound of the Daniel Hertz M7 easily fills the largest living room, but is equally enjoyable in a very small listening space. Hand polished stainless steel driver bezels enhance strength of the driver frame and provide ideal wave temination. All plates, screws and bolts are stainless steel. Positioning the M7 speakers The M7 can be placed against a wall or spaced out from the wall. Ideally, the two speakers (left and right) and the listening position should form an equilateral triangle. A dimension of 2 to 3 meters is typical, but can be varied according to the room and the listening area requirements. The M7 projects sound across long distances with focused dispersion and very little loss. This makes positioning more flexible than normal speakers. Your Daniel Hertz specialist will assist you in ideal placement of your M7 speakers. Video Sound: Surround vs Stereo A pair of Daniel Hertz M7 speakers provides incredible home theater sound. While surround sound attempts to create more involvement, the M7 provides a quality of sound - clarity, better dialogue, dynamics and punch - that most surround sound systems cannot begin to approach. People find that two M7 speakers far surpass what most surround sound systems do with regard to reproducing video sound tracks. While M7 s can be used in a surround sound format, most listeners find that it just isn t necessary, and enjoy the simplicity and elegance of having a pair of M7 s wthout a processor, additional cables, and more amplifiers and speakers cluttering the room.. Connections to the amplifiers Two channels of power amplification are required for the M7. Connect the red (+) and black (-) terminals of the M7 to the red (+) and black (-) terminals of the power amplifier(s). To hear the full sonic potential of the M7, use them with a pair of Daniel Hertz M5 TELIKOS Mono Reference power amplifiers and the Daniel Hertz M6 1 MegOhms Preamplifier. Daniel Hertz Silver 1 interconnect cables and Premium 500 speaker cable match the transparency of the M7. Compatibility with other power amplifiers Daniel Hertz M7 speakers are extremely efficient. Only 1 Watt of power produces 100dB of acoustic output (8 Ohms, 1M). Most people rarely use more than 1 Watt of power with the M7 speakers, needing milliwatts, not Watts of power for listening pleasure. In general, solid state power amplifiers do not excel in the milliwatt region. Vacuum tube amplifiers are often better suited to low power applications but suffer from other limitations such as damping factor, limited output current, and noise. The Daniel Hertz M5 offers exceptional performance in the milliwatt range with almost unlimited headroom and zero audible noise, as well as high reliability. 6 7

5 Operating Notes Keep the volume control of the preamplifier at OFF when the system is not being used, or at a very low level. Raise the volume to the desired level. The M7 can play with extreme power. It is better to raise the volume than to lower it! People often play the M7 at subjectively lower volume levels than other systems. This is due to the high level of detail and resolution, and the ability of the M7 to capture the peaks and beginnings of notes. The distortion is so low that it is easy to turn the volume up too high. Don t be surprised if you start listening and then turn down the volume. Listening on the M1 is different from other speakers. Feel free to turn up the volume to very high levels if you wish. Most people do not dare to turn up the volume, as they think the speaker will break. But if you continue to turn up the volume slowly, a little at a time, you will discover that it is possible to generate enormous sound pressure levels without stress or distortion. For playing at loud volume levels, choose music that is intended to be played like that. For example, a pop track like Burn by Usher sounds incredible at very loud levels. A solo piano recording by Artur Rubinstein will sound terrible played at such a level. Find the appropriate level for the music you want to hear. Keep in mind that the M7 will do things that other speakers cannot do. After listening a high volume levels, remember to turn down the volume control! Otherwise, you might scare yourself (and your neighbors) when you play the next selection. The M7 is friendly to a much wider variety of recordings than most speakers. Vintage recordings can come to life. Historical material becomes a new listening experience. Pop tracks can be reproduced at studio levels. You hear all the details in DVD and Blu-ray sound tracks. Compressed music files can sound remarkably good. The M7 is full of surprises. Music can be enjoyed anywhere in the room. You do not have to sit in a particular spot for musical enjoyment. For the ultimate listening experience, the ideal listening position is on center, 2M to 4M from the speakers. The M7 projects the sound all the way to the back of the room so you do not have to sit close to hear all the details. Listening closer to the M7 provides a more intimate experience.

6 Care and maintenance The Daniel Hertz M7 requires no maintenance. Dust and fingerprints can be removed with a light furniture polish. Avoid physical contact with the drivers. Do not pull on the speaker cables. If you attempt to physically move the M7, take care not to scratch the finish with a watch, ring or belt buckle.
