Features

The UTX-B03HR UHF Synthesized Transmitter is a
body-pack transmitter equipped with an SMC9-4S
connector designed for high reliability.

Reliable and proven SMC9-4S (female) interface

The unit is compatible with Sony ECM-77BC and ECM­44BC lavalier microphones, which have a proven record
of reliable performance in broadcasting.

Digital companding

The built-in DSP enables digital companding for high­quality audio transmissions. Switching to compander
mode allows operation in conjunction with Sony analog
wireless microphone system (UWP-D series, UWP
series, and WRR series) receivers.

LINE input equipped

MIC/LINE switching allows you to handle inputs from
various audio equipment.

Phase switching function

The phase switching function provides support for
reversed phase microphones.

Parts Identification

a Antenna

Infrared communication function

When operating in conjunction with UWP-D series
receivers, the frequency and compander mode settings
configured on the receiver can be received via the infrared
communication function, allowing you to complete
channel configurations quickly.

Flexible power supply options

The unit supports three types of batteries; alkaline, nickel
metal hydride, and lithium. Power can also be supplied
via USB.
When using nickel metal hydride batteries, you can
charge the batteries while they are inside the unit by using
a commercially available USB portable power supply.

b POWER indicator

Displays the battery level and charging status.

Indicator display Status

On (green) Sufficient battery level

Flashing (green) Battery is getting low

On (orange) Charging (when nickel metal hydride

rechargeable batteries are inserted
and power is turned off)

Off Power is off or charging is complete

c AUDIO (audio input level) indicator

Turns on or off according to the audio input level as
follows.
On (red): Audio input level is too high. If the sound is
distorted, adjust the attenuation level to decrease the
audio input level (page 11).

On (green): Audio input level is appropriate.
Off: There is no audio input or the input level is too low.
Flashing (orange): Audio is muted (i.e., disabled).

d Audio input connector (SMC9-4S type

(female))

Connect to Sony ECM-77BC and ECM-44BC lavalier
microphones. You can also connect other microphone
types by using EC-1.5CF microphone cable (not
supplied).

3

Note

When the audio input level is set to MIC, a voltage for the
lavalier microphone power supply is applied to the audio
input connector. When connecting equipment other than
lavalier microphones, always use an EC-1.5CF
microphone cable (not supplied).

e POWER/MUTING button

Turns the power on/off. You also use this button to turn
the muting function on/off.

f USB connector (Micro B type)

Connect to a commercially available USB portable power
supply.
When a USB portable power supply is connected while
the power is turned on, the unit automatically operates
with power supplied by the USB portable power supply.
When a USB portable power supply is connected while
nickel metal hydride batteries are inserted and the power
is turned off, the batteries are charged by the USB
portable power supply.

Note

Alkaline batteries and lithium batteries cannot be
recharged.

g Battery compartment

Accepts two AA batteries (alkaline, nickel metal hydride,
or lithium batteries).

For details on how to insert batteries, see “Power
Supply” (page 5).

h + or – button

Selects functions or values shown on the display.

A RF transmission indicator

Displays the current transmission status.

B RF transmission power indicator

Indicates the current transmission power setting. You can
change the setting with the RF transmission power setting
function.

For details on the RF transmission power setting
function, see “Setting the transmit output level (RF
POWER)” (page 11).

C Audio input level meter

Displays the audio input level.

D Peak indicator

Lights up when the signal is 3 dB below the level at which
distortion begins as a warning of excessive input level.

E Input level indicator

Displays the input level status.

F Battery level indicator

Displays the battery level. Displays “EXT” when power
is supplied from the USB connector.

For details, see “Battery level indicator” (page 6).

G Menu display section

Displays various functions. Press the + or – button to
switch functions.

For details, see “Configuration Menu” (page 11).

j SET button

Adjusts displayed function settings and applies the
displayed value.
Holding down the SET button while turning on the power
turns the transmitter on without transmitting a signal
(transmission stopped mode).

k Infrared detector

Receives the frequency and compander mode set on the
receiver.

Power Supply

The unit operates using power supplied from two AA
batteries (alkaline, nickel metal hydride, or lithium
batteries) or from a supply connected to the USB
connector. If power is supplied simultaneously from
batteries and from a supply connected to the USB
connector, power from the USB connector has
precedence. For details about inserting batteries and
displaying the battery level, or supplying power from a
supply connected to the USB connector, see the following
sections.

Note

The use of manganese batteries will result in poor
performance. Do not use manganese batteries.

Inserting the Batteries

Notes

• Always use sets of the same type of battery. Do not use
batteries of different types or batteries with different
charge level together.

• Replacing the batteries during operation may generate
a large noise. Be sure to turn off the unit before
replacing the batteries.

1

Press and hold the POWER/MUTING button to turn
the power off.

2

Slide the two catches inward (as indicated) and pull
the battery compartment out.

5

3

Insert two new AA batteries into the battery
compartment with 3 and # polarities in the correct
orientation, and close the compartment.

For details on the BATTERY function setting, see “Setting
the battery type (BATTERY)” (page 12).

Battery precautions

Batteries may leak or explode if mistreated. Be sure to
follow these instructions.

• Insert batteries in the correct 3 and # polarity
orientation.

• Always replace the two batteries together with new
ones.

• Do not use different types of batteries or old and new
ones together.

• Dry cells are not rechargeable.

• When not using the device for a long period of time,
remove the batteries. If the batteries leak for any reason,
contact your Sony service representative.

Make sure that the battery compartment is locked
securely.

Battery level indicator

Press and hold the POWER button for 1 second or longer
to display the battery level on the display.
Immediately replace both batteries with new batteries if
the indicator starts flashing (indication 5 below). If using
new alkaline batteries, use after checking the
recommended time limits.

Battery status

Supplying Power from a USB
Connector

The unit can operate from a commercially available USB­output type AC adapter or portable power supply
connected to the USB connector.
When supplying power using a USB-output type AC
adapter or portable power supply, use a unit that satisfies
the following conditions.

• Output connector: USB micro B type

• Rated voltage: 5 V

• Output current: 200 mA or higher

Displays “EXT” when power is supplied from the USB
connector.

Note

Noise may occur in the audio depending on the AC
adapter or portable power supply that is connected. In
such cases, you can reduce the noise by distancing the
unit or lavalier microphone from the AC adapter or
portable power supply or otherwise altering their
positions.

Notes

• When BATTERY is set to TYPE1, the battery level is
indicated based on the use of new LR6 (size AA) Sony
alkaline batteries. The battery level may not be
displayed correctly when different kinds of batteries,
different brand of batteries, or old batteries are used. If
using batteries other than size AA alkaline batteries,
select the battery type using the BATTERY function.

• If you plan to use the transmitter continuously for a long
period of time, it is recommended that you replace the
batteries with brand new ones.

Charging Nickel Metal Hydride
Batteries

You can charge nickel metal hydride batteries inserted in
the unit.
When charging nickel metal hydride batteries, turn the
power off and connect a commercially available USB­output type AC adapter or portable power supply to the
USB connector.
The POWER indicator is lit orange while charging
batteries. When charging is finished, the POWER
indicator goes off.
When charging batteries using a USB-output type AC
adapter or portable power supply, use a unit that satisfies
the following conditions.

• Output connector: USB micro B type

• Rated voltage: 5 V
