Features

The DWM-02N is a digital wireless microphone that

features an interchangeable microphone capsule unit

design, and is intended for use in UHF synthesized

wireless microphone systems. The DWM-02N can be used

in vocal performances, interviews, speeches, and a variety

of other applications.

What is DWX?

DWX refers to Sony’s new digital wireless microphone

system. The DWX series reflects Sony’s extensive

expertise in professional microphones and sound design. It

represents a successful blend of Sony know-how, wireless

technology renowned for stability, and cutting-edge digital

audio technology.

In addition to realizing the high sound quality possible

with a digital system, the DWX series supports multi-

mode. Audio quality is also improved when compared to

MODE1. We recommend using this mode under normal

circumstances.

MODE3: This audio codec mode prioritizes stable

transmission performance. Additional signal processing is

used to suppress noise and audio interruptions caused by

unexpected interference, resulting in more reliable

transmission.

The audio delay durations that occur when transmitting

and receiving with each mode will differ depending on the

receiver’s operating environment.

For details, refer to the operating instructions supplied

with the receiver.

The audio codec mode setting can be configured via the

wireless remote control function from the the receiver, for

example.

For details, see “Using the Cross Remote” on page 8.

Setting the maximum RF output

power (MAX RF POWER)

You can set the maximum RF output power of the unit.

1mW MAX: Sets the maximum to 1 mW.

10mW MAX: Sets the maximum to 10 mW.

50mW MAX: Sets the maximum to 50 mW.

• The setting for this function cannot be changed during

actual signal transmission. To change the setting, turn

off the transmitter first. Then, while holding down the

SET button, turn the power on. And then, change the

setting after the signal transmission has stopped.

• To start signal transmission with the selected RF output

power setting, turn off the power and then turn it on

again.

• Always perform pairing after changing the maximum

RF output power setting for a transmitter. If you fail to

do so, configuration of RF output power settings via the

wireless remote control function may become

impossible.

For details on pairing, see “Using the Cross Remote” on

page 8.

Generating an Internal Signal

(INTERNAL SG)

This microphone generates a 1-kHz reference level sine

wave that can be used to adjust or check the audio level of

the receiver or the system that you are using. This internal

signal is outside the control of the attenuator.

1kHz: A 1-kHz internal signal is generated.

OFF: An internal signal is not generated.

If the microphone is turned off while the reference signal

function is on, the function will turn off automatically.

Using wireless remote control, this function can be

controlled from the receiver and other devices.

For details on wireless remote control function, see

“Using the Cross Remote” on page 8.

Troubleshooting

If you encounter a problem using this microphone, use the following checklist to find a solution. For any problems with

the receiver, refer to the operating instructions supplied with the receiver. If the problem persists, consult your Sony dealer.

Symptom Meanings Remedy

The microphone does

not turn on.

The batteries are inserted backwards in the

battery compartment.

Reinsert the batteries with the correct orientation

(see page 5).

The batteries are exhausted. Replace the batteries with new ones.

The batteries drain

quickly.

Manganese batteries are being used. Use alkaline batteries.

The microphone is being used under cold

conditions.

The batteries drain quickly under cold conditions.

Interruptions in the

reception occurs.

The microphone is too far from the receiver. Decrease the distance to the receiver and check

the reception.

The transmission power setting is set to “L:

1mW”.

Increase the transmission power (see page 12).

There is no sound. The channel setting on the microphone is

different from that on the receiver.

Use the same channel setting on both the

microphone and receiver.

The setting of the encrypted transmission

function on the receiver is different from that on

the microphone.

Confirm that the setting of the encrypted

transmission function is the same on both the

microphone and the receiver (see page 9).

The audio codec mode settings on the receiver

and transmitter do not match.

Configure the same audio codec mode setting for

both the receiver and transmitter (see page 13).

The sound is weak. The attenuator is set too high for the audio input

level of the microphone.

While monitoring the audio input level meter on the

microphone or the receiver, set the attenuator to an

appropriate level (see page 12).

There is distortion in the

sound.

The attenuator is set too low for the audio input

level of the microphone.

The bass is weak. The frequency of the low-cut filter is set too

high.

While monitoring the sound, decrease the low-cut

filter frequency to a level that produces the proper

sound quality (see page 13).

There is too much bass. The microphone produces excessive bass

because the frequency response of the

microphone extends into the low range.

Use the low-cut filter to cut the bass (see page 13).

The power does not turn

off even though the

POWER switch is turned

to OFF.

The POWER switch is locked. Turn off the POWER SW LOCK function (see page

14).

Wireless remote control

is not possible.

Pairing has not been established between the

microphone and receiver.

Carry out pairing (see page 8).

The receiver is too far from the microphone for

communication to occur.

Check the wireless remote control condition level.

If it is low, decrease the distance between the

microphone and the receiver (see page 5).

The microphone that was paired with the

receiver has been paired with another receiver.

On the receiver, carry out pairing again with the

microphone that you want to control.

The USB keyboard does

not work.

You are using a USB keyboard that is not

compatible with the microphone.

Check the conditions for using a USB keyboard

with the microphone (see page 11).

The display is too dark. The display brightness is set to low. Adjust the brightness of the display (see page 14).

Important Notes on

Operation

Notes on Using the Microphone

• The digital wireless microphone system product must be

used within a temperature range of 0 °C to 50 °C (32 °F

to 122 °F).

• Operating the microphone near electrical equipment

(motors, transformers, or dimmers) may cause it to be

affected by electromagnetic induction. Keep the

microphone as far from such equipment as possible.

• The presence of the lighting equipment may produce

electrical interference over the entire frequency range.

Position the microphone so that interference is

minimized.

• To avoid degradation of the signal-to-noise ratio, do not

use the microphone in noisy places or in locations

subject to vibration, such as the following:

- near electrical equipment, such as motors,

transformers or dimmers

- near air conditioning equipment or places subject to

direct air flow from an air conditioner

- near public address loudspeakers

- where adjacent equipment might knock against the

tuner

Keep the microphone as far from such equipment as

possible or use buffering material.

On Cleaning

• If the microphone is used in a very humid or dusty place

or in a place subject to an active gas, clean its surface as

well as the connectors with a dry, soft cloth soon after

use. Lengthy use of the microphone in such places or not

cleaning it after its use in such places may shorten its

life.

• Clean the surface and the connectors of the microphone

with a dry, soft cloth. Never use thinner, benzene,

alcohol or any other chemicals, since these may mar the

finish.

Notes on Simultaneous Multi-Channel

Operation

• Keep the microphone at least 30 cm (11

inches) away

from another transmitter/microphone.

When the distances between transmitters and microphones

need to be closer than the distances above, use a grouping

system for multi-channel systems that include both digital

wireless and analog wireless devices.

For details, refer to “Sony Digital Wireless Microphone

System Frequency Lists” on the supplied CD-ROM.

• When only digital wireless microphones are being used,

keep the microphone at least 4 m (13 feet) away from the

antenna of a receiver for up to 10 channels, and at least

6 m (20 feet) away for 11 or more channels.

• When a mixture of digital and analog wireless

microphones/transmitters is being used, keep the

microphone at least 6 m (20 feet) away from the antenna

of a receiver.

• This system should be kept at least 100 m (328 feet)

away from any analog wireless systems using the same

frequency when both are being used in a wide area with

no walls or obstructions.

• If you experience noise, increase the distance between

the microphone and receiver or decrease the

transmission power on the microphone.

To prevent electromagnetic interference from portable

communication devices

The use of portable telephones and other communication

devices near the DWM-02N may result in malfunction and

interference with audio signals. It is recommended that

portable communication devices near the DWM-02N be

turned off.
