Compliance with this directive implies conformity to the following European standards: • EN55103-1: Electromagnetic Interference (Emission) • EN55103-2: Electromagnetic Susceptibility (Immunity) This product is intended for use in the following Electromagnetic Environment(s): E1 (residential), E2 (commercial and light industrial), E3 (urban outdoors), and E4 (controlled EMC environment, ex. TV studio). Attention: The electromagnetic fields at the specific frequencies may degrade the intended performance level of analog audio signals. FEATURES • Omni-directional characteristics with wide frequency range (30-18,000 Hz) • Two-way powering system using an internal battery or external power supply. • Ideal design for professional application in radio and TV studios or other audio fields because of its high quality performance and its extremely compact size. • Easy handling carrying case. PRECAUTIONS • The microphone should never be dropped or subjected to any excessive shock. • Keep the microphone away from extremely high temperatures (above 60°C or 140°F) • If the microphone is placed too near the speakers, a howling effect (acoustic feedback) may occur. In this case, decrease the speaker volume until the howling stops. • Microphone an recording instruments should be turned on 10 minutes before they are actually used. This assures stable performance of the microphones and instruments. PARTS IDENTIFICATION Microphone capsule Power supply section Supplied accessories Wind screen Microphone holders Output connector Double-clip microphone holder Horizontal microphone holder Vertical microphone holder BATTERY OPERATION 1 Open the battery compartment by turning the sleeve counterclockwise. 2 Insert an IEC designation R6 or LR6 (size AA) battery into the battery compartment. Check for correct polarity. 3 Close the compartment by turning the sleeve clockwise. Be sure to close the sleeve firmly, otherwise malfunction or noise may occur due to the loose fit. Notes • If the microphone is not to be used for a long time, remove the battery to avoid any possibility of corrosion. • In case of battery leakage, wipe off any deposit in the battery compartment. • Battery life depends on the battery type being used. Refer to the "Battery life" in "Specifications" below. When the battery is exhausted, sensitivity will be decreased and distortion will be heard. When this occurs, replace with a new battery. CONNECTIONS The output connector of the microphone is the Cannon XLR-3-12C type. Connect the microphone plug to the microphone input of a mixer or a tape recorder. The microphone cable is 3m (10 feet) long. If a longer cable is necessary, an extention cable up to 200 m (660 feet) may be used without affecting sound quality or performance. Use a cable with a Cannon XLR3-11C connector at one end and an appropriate plug at the other end which matches the input equipment. Note If cable connector connection is necessary, note that there are two basic types connections, balanced to ground and unbalanced to ground, and solder connections carefully. Poor soldering may cause hum pick up. EXTERNAL POWER SUPPLY The ECM-55B is designed for external powering (12 to 48 V DC) as well as internal battery power. The external power supply system consists of a DC power source, standard two conductor shielded microphone cable, and center-tapped transformer of the microphone. Use an external power supply unit available in marketplace. Notes • When an external power supply is used, the internal battery is not discharged. However, if an exhausted battery is installed while operating with external power supply, sensitivity will be decreased and noise/distortion will be heard. • For extending the cable between the power supply and the microphone, use a balanced-type cable. MORE ABOUT MICROPHONE USE • To eliminate the effect of wind or breath noise, cover the microphone with the supplied wind screen. This will attenuate wind or breath noise by 14 dB. • The supplied microphone holders are convenient for attaching the microphone to clothing. Be careful not to cover the microphone head. The double-clip microphone holder attaches two microphones to allow more stable operation. • Attach the microphone with cellophane or vinyltape to the inside of an instrument such as a guitar, bass, etc., to obtain a high quality sound. Be sure to place a rubber or felt cushion between the microphone and instrument.

Français Pour les clients en Europe Ce produit portant la marque CE est conforme à la Directive sur la compatibilité électromagnétique (EMC) (89/336/CEE) émise par la Commission de la Communauté européenne. La conformité à cette directive implique la conformité aux normes européennes suivantes: • EN55103-1: Interférences électromagnétiques (émission) • EN55103-2: Sensibilité électromagnétique (immunité) Ce produit est prévu pour être utilisé dans les environnements électromagnétiques suivants: E1 (résidentiel), E2 (commercial et industrie légère), E3 (urbain extérieur) et E4 (environnement EMC contrôlé, ex. studio de télévision). Attention: Les champs électromagnétiques à fréquences spécifiques peuvent dégrader le niveau de performance prévu des signaux audio analogiques. CARACTERISTIQUES • Caractéristiques omni-directionnelles avec large gamme de fréquences (30-18.000 Hz). • Deux possibilités d'alimentation: soit par batterie interne, soit par alimentation extérieure. • Conception idéale pour les travaux professionnels en studio de radio ou de télévision et autres applications audio en raison de ses performances de haute qualité et de sa remarquable compacité. • Etui de transport très pratique. PRECAUTIONS • Ne jamais laisser tomber le microphone ni le soumettre à des chocs. • Tenir le microphone à l'écart de toute source de température élevée (au-dessus de 60°C ou de 140°F). • Si le microphone est placé trop près des enceintes, une réaction acoustique (hurlement) se produira. Dans ce cas, réduire le volume des enceintes de manière à supprimer ce phénomène. • Le microphone et les appareils d'enregistrement doivent être mis sous tension 10 minutes avant leur utilisation proprement dite afin d'assurer la stabilité de leur fonctionnement. IDENTIFICATION DES ELEMENTS Capsule de microphone Section d'alimentation Connecteur de sortie Accessoires fournis Paravent Pinces de microphone Support de microphone pince double Support de microphone horizontal Support de microphone vertical FONCTIONNEMENT SUR PILE 1 Ouvrir le logement pile en tournant la douille dans le sens inverse des aiguilles d'une montre. 2 Installer une pile R6 ou LR6 selon la désignation IEC (format AA) dans le logement. Respecter les polarités. 3 Refermer le logement en tournant la douille dans le sens des aiguilles d'une montre. Refermer convenablement la douille; faute de quoi, une défaillance ou des parasites se produiraient. Remarques • Si l'on prévoit de ne pas utiliser le microphone pendant longtemps, en retirer la pile pour éviter toute possibilité de corrosion. • En cas de fuite d'électrolyte, essuyer convenablement tout dépôt dans le logement. • La durée de vie de la pile dépend de son type. Voir "Autonomie de la pile" sous "Spécifications" ci-après. Lorsque la pile est déchargée, sa sensibilité diminue et le son est déformé. Dans ce cas, remplacer la pile par une neuve. CONNEXIONS Le connecteur de sortie du microphone est du type Cannon XLR-3-12C. Raccorder la fiche du microphone sur l'entrée de microphone d'un mixeur ou d'un magnétophone.
