Since hearing damage from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association's Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for your protection. Decibel Level Example 30 40 50 60 70 80 Quiet library, soft whispers Living room, refrigerator, bedroom away from traffic Light traffic, normal conversation, quiet office Air conditioner at 20 feet, sewing machine Vacuum cleaner, hair dryer, noisy restaurant Average city traffic, garbage disposals, alarm clock at two feet. Selecting fine audio equipment such as the unit you've just purchased is only the start of your musical enjoyment. Now it's time to consider how you can maximize the fun and excitement your equipment offers. This manufacturer and the Electronic Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and clear without annoying blaring or distortion-and, most importantly, without affecting your sensitive hearing. Sound can be deceiving. Over time your hearing "comfort level" adapts to higher volumes of sound. So what sounds "normal" can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level BEFORE your hearing adapts. To establish a safe level: · Start your volume control at a low setting. · Slowly increase the sound until you can hear it comfortably and clearly, and without distortion. Once you have established a comfortable sound level: · Set the dial and leave it there. Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for a lifetime.

S001_En 2 En Before you start · The nominal impedance of this speaker system is 6 . Connect the speaker system to an amplifier with a load impedance ranging from 6 to 16 (a model with "6 ­ 16 " displayed on the speaker output terminals). In order to prevent damage to the speaker system resulting from input overload, please observe the following precautions: · Do not supply power to the speaker system in excess of the maximum permissible input. · When using a graphic equalizer to emphasize loud sounds in the high-frequency range, do not use excessive amplifier volume. · Do not try to force a low-powered amplifier to produce loud volumes of sound (the amplifier's harmonic distortion will be increased, and you may damage the speaker). Caution: installation · When placing this unit, ensure that it is firmly secured and avoid areas where it may be likely to fall and cause injury in the event of a natural disaster (such as an earthquake). · Do not attach these speakers to the wall or ceiling. They may fall off and cause injury. · Do not install your speakers overhead on the ceiling or wall. If improperly attached, the speaker grille can fall and cause damage or personal injury. · Switch off and unplug your AV equipment and consult the instructions when connecting up components. Make sure you use the correct connecting cables. Caution: in use · Do not place the speaker on an unstable surface. It could present a hazard if it falls, as well as damaging the equipment. · Do not use the speaker to output distorted sound for long periods of times. This can result in a fire hazard. · Do not sit or stand on the speaker, or let children play on the speaker. · Do not put large or heavy objects on top of the speaker. · Do not place magnetic objects such as screwdrivers or iron parts near the tweeter or midrange. Since the speakers use strong magnets, the objects may be attracted, causing injury or damaging the diaphragm.

K058_A_En 3 En About the EX series The EX series, incorporating the abundant technological know-how behind Pioneer's flagship TAD speaker series, was developed with the goal of creating the ultimate speaker possible in its price range. The design and production of the EX series result from an international effort that represents the finest in Pioneer's speaker technology. Bass Drivers Technology behind the S-4EX CST The core driver of the system is the Coherent Source Transducer (CST), which draws on the technology used in TAD. The tweeter diaphragm is mounted concentrically within the apex of the midrange cone and provides a point source of sound from 400 Hz to 100 kHz. The CST ensures a perfect spectral balance between the direct and reflected sounds that arrive at the listener's ears, providing a more consistent sound throughout the listening room and improved imaging capability. The bass driver pictured below serves as the foundation of the S-4EX speaker system. The driver's strength is the result of the Aramid/Carbon composite material, originally created during the development of the S-1EX, that is used in its diaphragm. Pioneer's exclusive LDMC magnetic circuit technology has been incorporated in order to preserve linearity from low to high output levels and minimize distortion. Bass Enclosure Construction Ceramic Graphite Diaphragm The CST's tweeter features a ceramic graphite diaphragm that provides top-level strength and dampening characteristics that are practically unrivaled by any other available materials currently used in high-end audio speaker systems. Ceramic graphite's lightness and exceptional strength combine to create speakers whose diaphragm resonance can be pushed far beyond their audible range. The unique form of the S-4EX is based upon logical necessity. In order to synchronize the arrival time of sound from the CST and the bass driver, each driver is mounted upon a baffle that serves to create a highly delicate curve known as the "precision curve" (see illustration below). Made of up to 65 mm thick MDF (Medium Density Fiberboard), this baffle is, moreover, strong enough to contain the force of the drivers. Additionally, the bass port has been carved out of an extremely thick block of MDF, resulting in the reduction of wind noise for clear, deep bass. Precision curve 3m Velocity (m/s) 18 000 16 000 14 000 12 000 10 000 8 000 6 000 4 000 2 000 0 0.005 0.015 Inner Loss 0.025 1m Crossover Networks The crossover networks use only the finest components. Air cored coils, noninductive resistors, and film capacitors in the signal path are all carefully chosen and optimized for the CST driver to provide the greatest transparency to the signal. The bass drivers use silicon steel plate core inductors that minimize distortion and loss during energy transfer. All components are connected directly to their respective wiring materials, instead of a printed circuitboard, allowing for minimal loss and maximum performance. Collaboration with Air Studios Since its establishment by George Martin in 1969, London, England's Air Studios has earned unequivocal respect from scores of artists who recognize it as the world's premier recording studio. The Air Studios seal that was awarded to the S-4EX indicates that these speakers are capable of producing the highquality sound demanded by the world's top-class sound creators. Magnesium Alloy Diaphragm The CST's midrange features a magnesium alloy diaphragm whose characteristic lightness and high inner loss provide excellent transience and minimal coloration of midrange sounds. 4 En Installation and Placement How to install Please observe the following points when installing speakers: These speakers are bookshelf-type speakers. They will provide best performance when placed on a solid level surface away from the floor. If placed directly on the floor, reverberation will be amplified, producing a boomy, undefined sound. Ideally, the high-range speakers (tweeters) should be placed at a height roughly the same level as the listener's ears. We recommend using the CP-4EX speaker stand for optimum sound and stability. When using the CP-4EX speaker stand, be sure to secure the speaker to the stand with the provided screws to prevent the speaker from falling. · Always use the spike bases as shown, with the indented surface facing up to receive the spike point. English Installing the spikes This speaker is provided with spikes and spike bases that should be used to produce optimum sound quality. If you do not use the spike bases when placing the speakers, the spikes may cause damage to the floor. If you plan on using the spikes we highly recommend to use the spike bases. Installation 1 Attach the spike nuts to the spikes. · As this unit weighs some 20 kg, it is very dangerous to try and set the spike nut while tilting the speaker. Be sure to place the unit on a soft area (such as a blanket) so that it does not damage the floor, and carry out the installation with at least two people. 2 Twist the spikes into the threaded metal inserts (M6) embedded in the bottom of the speaker. Consult the drawing and select either of the positions noted to fix the spikes. Attached in three positions Attached in four positions Attach the auxiliary ...
