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 denregistrement doivent  
être mis sous tension 10 minutes avant leur utilisation  
proprement dite afin dassurer la stabilité de leur  
fonctionnement.  
Check for correct polarity.

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 lifein Specificationsbelow.  
When the battery is exhausted, sensitivity will be  
decreased and distortion will be heard. When this  
occurs, replace with a new battery.

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.  
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.

*1 Wind noise is the value measured by applying a wind  
velocity of 2 m/sec. (6.6 ft./sec.) from all directions to  
the microphone. The mean value is taken and  
converted to the equivalent input sound level.  
0 dB SPL = 20µPa  
*2 The external magnetic field induction noise is  
measured with the microphone placed in an alternating  
magnetic field of 50 Hz, 1 milligauss.  
FONCTIONNEMENT SUR PILE  
1 Ouvrir le logement pile en tournant la douille dans le  
sens inverse des aiguilles dune montre.  
2 Installer une pile R6 ou LR6 selon la désignation IEC  
(format AA) dans le logement.  
EXTERNAL POWER SUPPLY  
Attention:  
The ECM-77B 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.  
The electromagnetic fields at the specific frequencies  
may degrade the intended performance level of analog  
audio signals.  
0 dB SPL = 20µPa  
*3 The maximum noise value is taken and then converted  
to the equivalent input sound level.  
FEATURES  
Omni-directional characteristics with wide frequency  
range (40–20,000 Hz)  
Respecter les polarités.  
0 dB SPL = 20µPa  
Notes  
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.  
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.  
Power requirements  
Normal operating voltage  
1.5 V DC at battery operation  
Minimum operating voltage  
1.1 V DC at battery operation  
External power supply  
For extending the cable between the power supply and  
the microphone, use a balanced-type cable.  
3 Refermer le logement en tournant la douille dans le  
sens des aiguilles dune montre. Refermer  
convenablement la douille; faute de quoi, une  
défaillance ou des parasites se produiraient.  
12 to 48 V DC  
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.  
Current drain Less than 0.2 mA (1.5 V DC) (with  
battery)  
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.  
Less than 2.0 mA (with external power  
supply)  
Remarques  
Si lon 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 pilesous Spécificationsci-après.  
Lorsque la pile est déchargée, sa sensibilité diminue et  
le son est déformé. Dans ce cas, remplacer la pile par  
une neuve.  
Battery life  
R6 manganese battery: Approx. 5,000  
hours  
LR6 alkaline battery: Approx. 6,000 hours  
Design and specifications subject to change without  
notice.
