Owner's Record The model and serial numbers are located on the bottom of the unit. [. . . ] n Fasten the ground lead securely to a metal point of the car. The voltage going into the remote terminal is too low. · The connected master unit is not turned on. · The system employs too many amplifiers. Check the battery voltage (10. 5 ­ 16 V). · The POWER/PROTECTOR indicator flashes. · The unit becomes abnormally hot. · Stereo operation: 2 ­ 8 ohms · Bridging operation: 4 ­ 8 ohms The speaker outputs are short-circuited. n Rectify the cause of the shortcircuit. The power connecting leads are installed too close to the RCA pin cords. The ground lead is not securely connected. n Fasten the ground lead securely to a metal point of the car. Negative speaker leads are touching the car chassis. n Keep the leads away from the car chassis. Guide de dépannage La liste suivante vous aidera à résoudre la plupart des problèmes que vous pouvez rencontrer avec cet appareil. Avant de passer la liste en revue, vérifiez les connexions et les procédures de fonctionnement. Problème Le témoin POWER/ PROTECTOR ne s'allume pas. Cause/Solution Le fusible a sauté. Le fil de masse n'est pas bien branché. n Fixez-le bien à une partie métallique de la voiture. La tension fournie à la borne de télécommande est trop faible. · L'appareil raccordé n'est pas sous tension. · Le système utilise trop d'amplificateurs. [. . . ] Par conséquent, vous devez raccorder des fils de calibre supérieur à 12 (AWG-12) ou d'une section supérieure à 3 mm 2 aux bornes +12V et GND. Subwoofer (min. 4 ) Note If you wish to use a subwoofer as the monaural speaker, connect the speaker as illustrated above. The output signals to the subwoofer will be a combination of both the right and left output signals. Remarque Si vous souhaitez utiliser un subwoofer comme hautparleur mono, raccordez le haut-parleur comme indiqué sur l'illustration ci-dessus. Les signaux de sortie du subwoofer sont constitués des signaux de sortie des canaux gauche et droit. 2-way System (with the optional XM-2501/2351 connected) Système à 2 voies (avec XM-2501/2351 en option) Car audio Autoradio Dual Mode System (with a Bridged Subwoofer) Double mode de connexion (avec subwoofer en pont) Car audio Autoradio (80Hz) OFF ON LPF LINE OUT LINE OUT XM-2351 XM-2501 HPF (80Hz) OFF ON FILTER (80Hz) HPF OFF LPF (80Hz) OFF ON LPF C1 C2 XM-2501/2351 XM-2751 Left speaker Haut-parleur gauche L Right speaker Haut-parleur droit Full range speakers (min.
