Features
The DWT-B30 is a digital wireless transmitter for a UHF
synthesized wireless microphone system to be used for
broadcast or movie production purpose. This transmitter is
suitable for Electronic News Gathering (ENG) and
Electronic Field Production (EFP).
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-
channel simultaneous operation, encrypted transmission,
and metadata transmission for monitoring the status of
multiple transmitters. Using a main link and a separate
additional link, remote control of transmitters from the
receiver is also possible. With its many advanced features,
the system has the potential to revolutionize the workflow
of professional applications.
What is WiDIF-HP?
WiDIF-HP (WiDIF: Wireless Digital Interface Format,
HP: High Profile) is a wireless digital audio interface
format developed by Sony.
It enables highly secure transmission with high sound
quality and low system latency, and supports simultaneous
multi-channel operation.
What is Cross Remote?
Cross Remote is a system that allows transmitters to be
monitored and controlled from a receiver and the Wireless
Studio control software installed on a computer connected
to the receiver.
For example, the settings of a transmitter worn under
clothing can be easily changed over the wireless link.
Simultaneous multi-channel operation
Simultaneous multi-channel operation is made possible
with the 375-kHz interval channel plan.
High sound quality and low latency
Low system latency of 1.2 ms (minimum) is achieved
when using CODEC MODE2.
Switch between four audio codec modes based on your
operational needs.
For details, see "Audio codec mode setting (CODEC
MODE)" (page 12).
Encrypted transmissions
AES 256-bit encryption allows for highly secure wireless
transmissions.
Switchable mic or line input level and
adjustable attenuator
Supports line/mic input and is equipped with an audio
attenuator that is adjustable in 3 dB steps up to a maximum
of 48 dB during mic input. The attenuator can be
controlled remotely from the receiver.
RF transmission output switching
available
RF transmission output can be set to 2, 10, or 25 mW
according to multi channel operation or long-distance
transmission priority.
For details, see "Setting the RF output power (RF
POWER)" (page 12).
User-set memory function
Various settings can be saved and activated on the
transmitter.
For further details, see "Settings storage function (USER
MEMORY)" (page 13).
USB for external power supply
An external supply enables operation for long periods of
time and power supply in emergencies.
Compact, lightweight, and rugged design
The unit is equipped with a magnesium-alloy casing,
providing a body that is durable in addition to being
compact and lightweight.
Supports operation for long periods of
time and various battery types
The DWT-B30 supports various battery types, such as AA
alkaline batteries, lithium ion batteries, and NiMH
batteries. It can be operated for approximately 6.5 hours
when powered by alkaline batteries.
Organic EL (electroluminescent) display
The quick response of the OLED (organic light-emitting
diode) display enables real-time operating conditions to be
displayed clearly and accurately.
