For the cutomers in Europe

This product with the CE marking complies with the EMC Directive (89/336/EEC) issued by the Commission of the European Community.

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

•Wide unidirectional characteristics with wide frequency range (70–14,000 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.

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.

4 Set the BATTERY switch to ON.

The BATTERY indicator momentarily lights up and then turns off. This indicates that the battery voltage is within the operable range.

To check the battery condition

Set the BATTERY switch to OFF, then wait for more than 5 seconds, and then set the switch to ON and see if the BATTERY indicator lights up or not. If the indicator does not light up, the battery has exhausted.

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 XLR- 3-11C 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-66B 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 the output connector is connected to the external power supply unit, the power is automatically supplied from the unit even if the battery is inserted and the BATTERY switch is set to ON.

The internal battery can serve as a backup power source in case of a power failure. If the backup power source is unnecessary, set the BATTERY switch to OFF or remove the battery from the battery compartment.

•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 20 dB.

CARACTERISTIQUES

•Caractéristiques unidirectionnelles larges avec large gamme de fréquences (70–14.000 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.

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.

4 Régler le commutateur BATTERY sur ON.

Le témoin BATTERY s’allumera momentanément, puis s’éteindra. Cela indique que la tension de la pile est dans la plage de fonctionnement.

Pour contrôler l’état de la pile

Régler le commutateur BATTERY à OFF, attendre au moins 5 secondes, puis le remettre sur ON et regarder si le témoin BATTERY s’allume ou non. S’il reste éteint, la pile est épuisée.

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.
