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.
