FEATURES

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.

Supplied with three types of microphone holders to be used according the



situation and a convenient and compact storage case.

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.

English

Before operating the unit, please read this manual thoroughly. This manual

should be retained for future reference.

Electret Condenser

Microphone

Operating Instructions

ECM-55B

CONNECTIONS

The output connector of the microphone is the XLR-3-12C type. Connect the

microphone plug to the microphone input of a mixer or a tape recorder. The

microphone cable is 3 m (10 feet) long.

If a longer cable is necessary, an extension cable up to 200 m (660 feet) may

be used without affecting sound quality or performance. Use a cable with an

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

of connections, balanced to ground and unbalanced to ground, and solder

connections carefully. Poor soldering may cause hum pick up.

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 used too close to speakers, the sound from the speakers



will be picked up and produce a howling effect (i.e., acoustic feedback). To

prevent howling, avoid facing the microphone toward the speakers and

maintain as much distance from the speakers as possible.

Microphone and recording instruments should be turned on 10 minutes



before they are actually used. This assures stable performance of the

microphones and instruments.

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

the 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 reduce the effect of wind or breath noise, attach the supplied wind screen



to the microphone.

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.
