Introducing the new DWZ Series from Sony
Features
Intelligent Feedback Reducer
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. Also, the equivalent of
maximum 1024-band suppression filters 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 filter to
apply – for example, you can output original audio to the
main PA system, while processed audio is delivered to your
monitor speakers.
Superb Digital Sound Quality
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 analogue wireless
systems is avoided, because these digital wireless packages
are designed without the need for a compander.
Stable Transmission
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.
Highly Secure Transmission
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 information could
be intercepted.
Robust Metal Body
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.
Two RF Modes for Reliable 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.
Wide Band Hopping Mode This mode reduces interference with
other wireless equipment used in the same environment, such as
wi-fi 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*.
Narrow Band Hopping Mode 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**.
* Latency of approximately 6 ms.
** Latency of approximately 3 ms.

Interchangeable Capsules
With the handheld transmitter, you can use
the supplied high-quality dynamic cardioids
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)*.
* Use of third party capsules may cause RFI or EMF noise.
