2.5.1 Wiring Basics

Always use shielded wire for input wiring. The higher the density of the shield (the outer conductor) the better. Spiral wrapped shield is not recommended.

When using unbalanced lines keep the cables as short as possible. Avoid lengths greater than 10 feet (3 meters).

Do not run the audio input cables together with the high- level wiring such as loudspeaker wires or AC cords. (This lessens the chance of hum and noise being induced into the input cables.)

Turn the entire sound system off before changing any connections. Crown is not liable for damage incurred when any transducer or component is overdriven.

THE CHANNEL 2 INPUT IS IGNORED if the amplifier is used in Bridge-Mono mode.

For additional information on audio input wiring please refer to the Crown Amplifier Application Guide avail- able online at www.crownaudio.com. It contains helpful information on preventing unwanted subsonic frequencies, radio frequency interference, ground loops, and feedback oscillation.

When using network connections, pass the CAT5 cable seven times through a ferrite core (Figure 2.4), available from Crown Audio Inc. This is to ensure compliance with emission regulations.

2.5.1 Principes de câblage

Utilisez toujours du fi l blindé pour la ligne d’entrée. Plus la densité du blindage est élevée (le conducteur extérieur), meilleures sont les performances. Le blindage enroulé en spirale n’est pas recommandé.

Si vous utilisez des lignes déséquilibrées, faites en sorte que les câbles soient les plus courts possible. Evitez des longueurs supérieures à 3 mètres.

Ne faites pas courir des câbles d’entrée audio avec le câblage haut niveau, tel que les fi ls de l’enceinte ou les cordons courant alternatif. (Cela diminue les risques de ronfl ement et de bruit induits dans les câbles d’entrée).

Mettez le système de sonorisation complet hors tension avant de modifier les raccordements. Crown n’est pas tenu responsable des dégâts occasionnés à la suite de la surcharge d’un transducteur ou d’un composant.

L’ENTRÉE DU CANAL 2 EST IGNOREE si l’amplificateur est utilisé en mode Pont-Mono.

Pour obtenir des informations supplémentaires sur la ligne d’entrée audio, référez-vous au Guide d’application de l’amplifi cateur Crown, disponible en ligne à www. crownaudio.com. Il contient des informations utiles sur la manière d’éviter les fréquences subsoniques indésirables, les interférences de fréquence radio, les boucles de masse et l’oscillation de rétroaction.

En cas d’utilisation des connexions réseau, passez le câble CAT5 sept fois dans un tore de ferrite (Figure 2.4), disponible chez Crown Audio Inc, afi n de satisfaire les exigences en matière de réglementation des émissions.

2.5.1基本配线

输入配线应全部使用带屏蔽线。屏蔽程度 越高(外部导线),使用效果越好。建议 不要使用螺旋包绕屏蔽。

如果使用不平衡线路,则应使用尽可能 短的电缆。电缆长度应少于 10 英尺( 3 米)。

音频输入电缆不能与高等级配线(比如 扬声器线或交流电缆)一起走线。(这 样可以减少输入电缆产生电磁噪声的机 会。)

在变更任何连接之前应关闭整个声音系 统。对于任何转换器或部件过载导致的损 失,皇冠音响公司概不负责。

如果放大器采用桥接-单声道模式,则忽 略声道 2 输入。

有关音频输入配线的更多信息,请参考 皇冠音响公司放大器使用指南(可通过

如果使用网络连接,则应将 CAT5 电缆七 次通过铁氧体磁芯(图 2.4),这样可以 确保符合放射规定。铁氧体磁芯可从皇冠 音响公司获得。

Use siempre cable blindado para el cableado de entrada. Un cable con blindaje (el conductor externo) de más alta densidad es mejor. No se recomienda el uso de blindaje envuelto en espiral.

Cuando use líneas no balanceadas mantenga los cables tan cortos como sea posible. Evite el uso de cables de más de 3 metros (10 pies) de longitud.

Evite que corran en paralelo los cables de entrada

de audio junto con el cableado de alto nivel, como los cables de altoparlantes o de suministro eléctrico. Esto minimiza la presencia de zumbidos y de inducción de ruidos hacia los cables de entrada.

Apague todo el sistema de sonido antes de cambiar cualquier conexión. Crown no se hace responsable de daños por sobrecarga de cualquier transductor o componente.

LA ENTRADA DEL CANAL 2 ES IGNORADA si el amplifi - cador se usa en modo Bridge-Mono.

Si requiere información adicional sobre cableado de entrada para audio, consulte la Guía de Aplicación de Amplifi cadores Crown disponible en línea en www.crown- audio.com. Esta guía contiene información útil para evitar la presencia de frecuencias subsónicas no deseables, de interferencia de radio, diferencias de potencial a tierra y oscilación por retroalimentación.

Cuando use la conexión a redes, pase el cable tipo CAT5 siete veces a través de un núcleo de ferrita (Figura 2.4), que está disponible a través de Crown Audio Inc. Esto se efectúa para cumplir los reglamentos sobre emisiones electromagnéticas.
