• 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.
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 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.

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 d’une 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 d’une 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 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.
