Features
The DWT-B01 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 are the strengths of a
Digital Wireless Microphone
System?
This system has the following special
features and qualities:
• High-quality audio signal transmission
approaching to the quality of wired
microphone
• Extremely tolerant to interference waves
and secure wireless transmission
• Simultaneous multi-channel operation
• Encrypted transmission
• Metadata transmission.
Note that the DWT-B01 digital wireless
transmitter cannot be used to transmit to
analog wireless receivers.
The features of this transmitter are
described below.
Wide RF carrier frequency
range
The DWT-B01 transmitter covers an
extremely wide RF carrier frequency range.
The U3040 and U4250 models (US models)
can cover a 66-MHz band and 60-MHz
band respectively — much wider than 24-
MHz of the analog wireless microphone
system, while the CE6267 model
(European model) can cover a 48-MHz
band. This remarkably wide coverage on a
single model offers cost efficiency and
operational convenience, because it allows
one transmitter to be operated in many
different areas.
Compact, lightweight, and
rugged design
The DWT-B01 is designed to be extremely
compact and lightweight, essential qualities
for use by artists in fast-moving TV and
outdoor productions.
Switchable mic or line input
level and adjustable
attenuator
The audio input level of the DWT-B01 is
selectable from either MIC or LINE.
When MIC is selected, the attenuator can be
adjusted in 3-dB steps from 0 dB to 48 dB.
The reference input level of the MIC and
LINE is –58 dBu (–60 dBV) and +4 dBu,
respectively.
Selectable RF output power:
1 mW, 10 mW, and 50 mW
The 1 and 10 mW output is suitable for
multi-channel operations, while the 50 mW
output is intended for long-distance.
Power sleep mode
The DWT-B01 is equipped with a power
sleep/wake up mode that can be wirelessly
controlled from an optional digital wireless
receiver.
Digital low-cut filter
Equipped with a digital low-cut filter, the
DWT-B01 can reduce the effects of
undesired ambient noise.
