Experience stable and reliable sound from Sony. The DWZ-M70 package with
a handheld microphone, and the DWZ-B70HL package with a headset and
lavalier microphone provide clear voices for your audience by eliminating
unwanted acoustic feedback noise, using Sony’s advanced integration of
DSP functions. With 24-bit linear PCM digital transmission, you get high sound
quality with high reliability, utilizing unique transmission technology also
developed by Sony. With the support of two RF modes, your audio signal can
be captured and transmitted reliably and easily.
Great Performances for Presenters and Vocalists
High-quality 24-bit linear PCM digital transmission
offers a pristine audio experience, and a wide
frequency range of 10 Hz to 22 kHz. With these
high-quality digital sound packages, you can
experience professional performances by
presenters and vocalists. The audio performance
degradation that’s typical with conventional
analog wireless systems is avoided, because
these digital wireless packages are designed
without the need for a compander.
Superb Digital Sound Quality
DWZ-M70
DWZ-B70HL
The Sony Intelligent Feedback Reducer
can suppress unwanted feedback (howling)
with high-performance DSP and Sony’s unique
algorithms designed to eliminate feedback
before it becomes unbearable. Up to 1024-band
suppression lters are continuously tuned
automatically in real time, eliminating feedback
and avoiding deteriorating the original signal;
this delivers the highest quality sound that can be
enjoyed by presenters, vocalists, and audiences.
You can freely select the audio outputs to
which you want this feedback reduction lter to
apply – for example, you can output original
audio to the main PA system, while processed
audio is delivered to your monitor speakers.

Interruptions in reception (signal dropout) can be
a problem with wireless microphone transmission
systems. With the DWZ Series, however, the
occurrence of signal dropout can be reduced to
a minimum. Utilizing a space diversity reception
system, this series achieves stable reception by using
dual antenna inputs/reception circuits. These receive
signals over two different paths and automatically
select the stronger RF signal for output.
Stable Transmission
The DWZ-M70 package and DWZ-B70HL package
provide two selectable RF modes. Simply choose
the one that makes best use of your actual 2.4-GHz
RF environment.
Two RF Modes for Reliable Transmission
This mode reduces interference with other wireless
equipment used in the same environment, such as
wi- devices. It doesn’t require you to have technical
knowledge about radio frequencies. Wide Band
Hopping Mode also supports additional error
correction for more secure transmission*.

* Latency of approximately 6 ms.
This mode helps you to avoid interference from other
devices – for example, 2.4-GHz wireless remote
controllers that are commonly used for lighting control.
This enables you to coordinate frequencies when
using multiple wireless systems simultaneously**.

The BC-DWZ1 optional battery charger enables
you to recharge NiHM batteries in the ZTX-M02RC
and the ZTX-B02RC. The BC-DWZ1 is a contactless
recharger; this means that you simply place the
handheld microphone and/or bodypack transmitter
into the charging station to
recharge NiMH-type batteries.
You do not need to physically
remove the rechargeable
batteries to recharge them, which
saves you time and reduces
wear and tear to the transmitters.

DWZ-M70 DWZ-B70HL
The ZTX-M02RC handheld microphone (supplied
with the DWZ-M70 package) and the ZTX-B02RC
bodypack transmitter (supplied with the DWZ-B70HL
package) are made of strong durable metal. Metal
construction supports reliable use in rough
operating conditions.

These two DWZ Series packages both offer 128-bit
standard encryption technology to secure
transmitted signals and avoid being intercepted
by others. By using this encryption feature, users
can reduce the worry that confidential
info r m a tion could be intercepted.
Highly Secure Transmission
*BC-DWZ1 and NiMH battery are sold separately.

The DWZ-B70HL package includes two types of
microphones. The ECM-HZ1UBMP is a uni-directional
electret condenser lightweight headset that keeps
you comfortable and stress-free even when wearing
it for long periods of time. Its ear-clip-style design
allows you to wear it on either your left or right ear.
The ECM-LZ1UBMP is a uni-directional electret
condenser lavalier microphone, ideal for commercial
sound applications such as presentations, lectures,
and conferences.
Headset & Lavalier Microphones
With a five-band digital equalizer in the half-rack
ZRX-HR70 receiver, you can adjust the sound
character of your microphone as desired.
The bodypack transmitter muting switch allows you to
select specic outputs on the receiver to be muted.
You can select to mute all outputs, XLR/Main outputs,
or the AUX/Tuner output. This feature provide you
with many operational choices – for example,
talkback operation.
Five-band Equalizer
Selectable Muting Output
Adjustable transmitter attenuators allow you to
select proper audio input levels from the microphone.
The bodypack transmitter (included with the
DWZ-B70HL package) can also support line level
audio input signals, plus it can be used in
conjunction with the optional EC-1.5BX XLR input
cable when needed.

With the handheld transmitter, you can use
the supplied high-quality dynamic cardioid
microphone capsule. Alternatively, you can
select any optional mic capsule from Sony’s
DWX Series capsules (the thread pitch is
1.25”/28; 31.3 mm/pitch 1.0 mm threading)*.

The half-rack ZRX-HR70 has Clear Channel Scan
and Best Channel Selection features that can detect
unoccupied channels and select the most
appropriate channel automatically. These features
allow you to achieve fast and easy system setup.
