Features
The DWZ series is a digital wireless system
that combines Sony’s consistently
developed superior audio technology,
highly reliable wireless technology, and
state-of-the-art digital signal processing
technology. Using an unlicensed 2.4 GHz
band, the system provides wide-range
functionality with simple, user-friendly
operability.
By providing a package that is optimized
for specific usage environments, the system
offers a wireless solution to users ranging
from those inexperienced with wireless
systems to seasoned professionals.
A new microphone that can
comprehensively pick up the wide dynamic
range produced by instruments has also
been developed (DWZ-B50I).
Superb audio quality
By transmitting audio signals via 24-bit
high-quality linear PCM digital
transmission, without signal compression,
decompression (available only when the RF
mode is set to Narrow Mode (NARROW)),
or similar processing, the system provides
superb audio quality and high-bandwidth
transmissions that approach that of wired
microphones.
High reliability
By allowing you to select from two RF
modes based on your intended use and
incorporating Sony’s unique data
processing technology, the system provides
highly-reliable wireless transmission in
wireless LAN environments. In addition,
the two RF modes each consist of six
channels, allowing you to select the
appropriate RF mode and channel
according to your intended purpose. The
receiver is equipped with two antennas with

6Features
the antenna with the best reception status
selected automatically via space diversity,
providing stable reception with minimized
audio breakup and noise occurrences.
DWZ-B50I
The DWZ-B50I is a package that includes a
microphone ideal for use with saxophones,
trumpets, and other wind instruments, a
body-pack transmitter (ZTX-B01), and a
half-rack receiver (ZRX-HR50).
DWZ-B50GB
The DWZ-B50GB is a package that
includes a body-pack transmitter
(transmitter: ZTX-B01) and a half-rack
receiver (receiver: ZRX-HR50) and is ideal
for use with electric guitars, electric
acoustic guitars, electric bass guitars, etc.
ZTX-B01
A transmitter designed with a sturdy metal
body.
Equipped with a muting function, an
instrument/mic input switching function,
and an attenuator adjustment function, the
unit supports a wide range of audio input
levels. The supplied belt clip can be rotated
in 90-degree increments, allowing you to
adjust the direction in which the cables
extend based on your environment.
ZRX-HR50
A half-rack receiver equipped with large-
screen high-resolution color LCD that
combines high-functionality with simple
operability.
The Best Channel Selection and Clear
Channel Scan functions allow quick and
easy configuration of safe channels. The
cable tone generator also allows you to
match the quality of wireless and wired
audio. This reduces the amount of equalizer
adjustment necessary on the amp side
during wireless transmission. In addition,
the 5-band graphic equalizer allows wide-
range audio-quality adjustment. You can
also select whether the muting function
applies to the UNBALANCED/
BALANCED OUTPUT connector.
Using the optional RMM-HRD1 Rack
Mount Kit allows you to mount the unit on
a rack.
