CR97 CR77 CR67 CR57 CRC7 High performance compact speakers ENGLISH ESPAÑOL FRANÇAIS DEUTSCH ITALIANO CR97 · CR77 · CR67 · CR57 · CRC7 High performance compact speakers Description Continuing in the tradition of our critically acclaimed Compact Reference series, the new CR series products are versatile, high performance bookshelf and floorstanding loudspeakers designed to deliver accurate, natural reproduction. Special care has been taken to optimize the speakers components for maximum performance. The bass and midrange units utilize phase plugs that conduct heat away from the voice coil, thus increasing power handling and maximizing output. The woofer cones and surround geometry were designed and optimized with Finite Element Analysis (FEA) computer modeling technology, for strong bass and smooth midrange. High frequencies are handled by Boston's exclusive 1inch (25mm) or 3/4-inch (19mm) Kortec tweeter mounted in an innovative new wide dispersion projection tweeter baffle. This remarkable driver produces an extremely smooth, flat response well beyond the audible range. An aluminum heatsink attached to the tweeter's back plate dissipates heat quickly and efficiently, assuring cool, trouble free operation--even at very high power levels. All the drive units are designed at Boston's Peabody, Massachusetts facility using state-of-the art computerdesign programs, and are built on Boston's proprietary production lines to an incredible ±1dB--perhaps the industry's tightest tolerance. The CRC7, CR77, and CR97 feature MagnaGuard®, magnetic shielding for safe placement near any sized television set. The drivers are positioned very closely to each other for smooth, uniform radiation in both the horizontal and vertical planes. The rear-mounted vent is smoothly flared to reduce port turbulence, and all speakers feature five-way binding posts, allowing wiring with virtually any cable. How to Place Your Speakers SPECIFICATIONS CRC7 Frequency Response (±3dB) 80Hz-20kHz Recommended Amplifier Power 15-100 watts Nominal Impedance 8 ohms Sensitivity [1 watt (2.83v) at 1m] 89dB Bass unit 4 1/2" (115mm) Passive Radiator 4 1/2" (115mm) ENGLISH Mounting Options Your CR speakers have several convenient mounting options: STAND OR SHELF: Peel off the included rubber feet from their adhesive backing and stick them on to the four bottom corners of each speaker. KEYHOLE BRACKET: Consult a knowledgeable installer regarding the proper hardware to use on your wall surface. A 1-inch (25mm) long wall anchor is recommended for hollow walls. Regardless of the type of wall fastener used, the screw head diameter should be between 5/16 and 3/8inch (8 to 9.5 mm) to fit properly inside the keyhole and slide down on to the slot. Apply the rubber feet the rear of the speaker to prevent any scratching or marring of the wall surface. Note: The CRC7 features two keyhole brackets allowing vertical or horizontal placement--perfect for using three in an L/C/R application around a wall mounted flat panel television.

To achieve this effect, place the speakers 6 to 12 Ft. (2­4m) apart, so they form a triangle with your favorite listening position. For home theater applications place the left and right speakers on each side of the television, as you would place them in a stereo application. Place center channel speaker as shown below, with the front of the speaker flush with the front of the television (the center speaker can be placed either above or below the television). When using the CR speakers as surround speakers, they can be placed on the side or back walls. Recommended placement is above ear level on the side walls behind the listening position. However, experimentation will yield the best possible results for every room. If possible, permanent mounting of the CR speaker should only be done after the optimum location is determined. When using the CR speakers in a home theater application you will want to add a subwoofer. There are many Boston solutions available; the best solution depends on available space and the size of the room. To discover all of the options available, please consult your Boston Acoustics dealer. For all applications, the speakers should be at least 18-inches (0.6m) from the corners of the room. Putting the speakers too close to a corner can produce an unnatural bass reinforcement that detracts from their balanced, uncolored sound. If a speaker must be placed near a corner, move it away from the wall directly behind it to preserve its natural tonal balance.

Wiring should take just a few minutes, but it's important to do it carefully, since incorrect wiring (such as reversed connections) can result in a poor soundstage and poor bass. We recommend 18-gauge wire or thicker for runs up to 18ft. (6m), and 16gauge wire or thicker for longer runs. Separate the first few inches of the wire conductors. Strip off about 1/2-inch (12mm) of insulation from the ends of each speaker wire to expose the two conductors and tightly twist the wire strands. WARNING: To prevent electrical shock hazard, always switch off the amplifier or receiver when making connections to the speaker. When making all connections, be sure to connect the + (red) on the speaker to the + (red) on the amplifier, and the ­ (black) on the speaker to the ­ (black) on the amplifier. CRB BRACKET: This optional stand-off/swivel bracket can be purchased from your dealer or ordered directly from Boston Acoustics. The CRB attaches to the back of the speaker using the four mounting holes located at either side of the keyhole bracket. Instructions on how to attach this bracket to the speaker and mount the assembly to the wall are supplied in the CRB kit. Rotating the Logo The CR grille logo can be rotated 90° in either direction when mounting the speaker horizontally or to maintain symmetry from left to right. The logo is spring loaded; to rotate the logo, simply spin it into the desired position. Subwoofer Right Surround Speaker 5-8 ft. (1.6-2.6m) 6-12 ft. (2-4m) Left Speaker Center Speaker Right Speaker + IMPORTANT: Typically, one side of the wire is smooth. Connect this side to the ­ (black) connection. The other side has a rib or stripe. Connect this to the + (red) connection. Using the five-way binding posts: The binding posts permit easy connection to banana plugs, spade lugs, and bare wire. Insert the wire in the hole and tighten. Left Surround Speaker Listening Levels and Power Handling The listed power recommendations assume you will operate your system in a way that will not produce distortion. Even these rugged speakers can be damaged by a modest amplifier if it produces distortion. If you hear a harsh, gritty noise, turn down the volume. Prolonged or repeated operation of your speaker with a distorted signal from the amplifier can cause damage that is not covered by the warranty. If Service Seems Necessary First, contact the dealer from whom you purchased the speakers. If that is not possible, write to: Boston Acoustics, Inc. 300 Jubilee Drive, Peabody, MA 01960 U.S.A. We will promptly advise you of what action to take. CR97 · CR77 · CR67 · CR57 · CRC7 Altavoces compactos de altas prestaciones Descripción Siguiendo con la tradición de nuestra aclamada serie Compact Reference, los nuevos productos de esta serie son unos altavoces versátiles, de altas prestaciones, tanto para estantería como para el suelo, diseñados para proporcionar una reproducción fiel y natural. Se ha tenido un cuidado especial en optimizar los componentes de los altavoces para obtener las máximas prestaciones. Las unidades de graves y de frecuencias medias utilizan conectores de fase que alejan el calor de la bobina móvil de altavoz, aumentando así la gestión de potencia y maximizando la salida. Los conos del altavoz de graves y la geometría ambiental se han diseñado y optimizado con la tecnología de modelado informatizado de análisis de elementos finitos (FEA) para conseguir unos graves fuertes y unas frecuencias medias suaves. Las altas frecuencias se gestionan mediante el altavoz de agudos Kortec de 25 mm o 19 mm exclusivo de Boston, instalado en una innovadora y nueva caja acústica de altavoz de agudos de proyección con dispersión amplia. Este asombroso controlador produce una respuesta plana extremadamente suave muy por encima del rango audible. Un disipador térmico de aluminio instalado en la placa posterior del altavoz de agudos disipa de forma rápida y eficaz el calor, asegurando un funcionamiento frío y sin problemas, incluso a niveles de potencia muy altos. Todas las unidades están diseñadas en la fábrica de Boston en Peabody (Massachussets) usando la más avanzada tecnología informática, y están construidos en las línea de producción propiedad de Boston con una tolerancia increíble de ±1 dB, quizá la más pequeña del sector. Los CRC7, CR77 y CR97 incorporan el blindaje magnético MagnaGuard®, para poder colocarlos de forma segura cerca de cualquier aparato de televisión, independientemente del tamaño. Los controladores se colocan muy cerca el uno del otro para obtener una radiación suave y uniforme en los planos horizontal y vertical. La ventilación trasera está suavemente acampanada para reducir las turbulencias del puerto, y todos los altavoces incorporan bornes de conexión de cinco vías, lo que permite realizar el cableado con prácticamente cualquier cable.

SOPORTE DE BOCALLAVE: Consulte a un instalador con experiencia en relación con los accesorios de ferretería adecuados para usar en la superficie de la pared. Se aconseja la utilización de un ancla de pared de 25 mm de longitud para paredes huecas. independientemente del tipo de sujeción de pared que se haya usado, el diámetro de la cabeza del tornillo debe tener entre 8 y 9,5 mm para que encaje correctamente dentro de la bocallave y se pueda deslizar en la ranura. Coloque los pies de goma por detrás del altavoz para evitar que se ralle o estropee la pared. Nota: El CRC7 incorpora soportes de bocallave que posibilitan la colocación vertical u horizontal, y que son perfectos para usar tres en una aplicación I/C/D sobre una televisión de panel plano sobre pared.

Para lograr este efecto, coloque los altavoces de 2 a 4 m de separación entre ellos, de modo que formen un triángulo con su posición de escucha favorita. Para aplicaciones de cine casero, coloque los altavoces izquierdo y derecho a cada lado de la televisión, como lo haría en una aplicación estereofónica. Coloque el altavoz del canal central como se muestra más abajo, con la parte delantera del altavoz y la del televisor niveladas (el altavoz central se puede colocar por encima o por debajo de la televisión). Cuando use los altavoces CR como altavoces ambientales, se pueden colocar en las paredes laterales o en la trasera. La colocación recomendada es por encima del nivel de audición en la pared lateral, ...
