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.
Superb audio quality
By transmitting audio signals via 24-bit high-quality
linear PCM digital transmission (available only when the
RF mode is set to Narrow Mode (NARROW)), without
signal compression, decompression, 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 the
antenna with the best reception status selected
automatically via space diversity, providing stable
reception with minimized audio breakup and noise
occurrences.
Highly confidential transmissions are also possible using
the 128-bit AES (Advanced Encryption Standard).

reduction function
The ZRX-HR70 is equipped with an intelligent feedback
reducer.
This function uses a unique algorithm that processes
signals in real time to prevent the acoustic feedback noise
that occurs when a microphone is brought in close
proximity to speaker output.
The function eliminates the need for complicated
parameter adjustments according to room size, speaker
positions, etc., and allows you to select from three
different effect levels based on you environment.
This allows you to use the system without speaker
position being a major concern. [Effect Level] is set to
[OFF] and [Apply Feedback Reducer] is set to [To All
Outputs] under factory default settings.

Channel Frequency List 17
Channel Frequency List
The frequencies used by the Wide Band (WIDE, channels 1 to 6) and the Narrow Band (NARROW, channels a to f) are
as follows.
Each channel uses multiple compatible frequencies to increase reliability and redundancy. The appropriate frequencies are
used according to the surrounding wireless environment.
To ensure transmission quality, do not place transmitters and receivers near wireless routers or computers.
Wide Band
• Enables more stable RF transmission
• Delay time: Approx. 5 milliseconds
The Wide Band (WIDE) mode allows you to reduce
effects to other wireless equipment without extensive
knowledge of wireless frequencies. This mode includes
signal processing to provide more stable transmissions
than in Narrow Band mode.
Narrow Band
• Enables 24-bit linear PCM high-quality digital
transmission
• Delay time: Approx. 3 milliseconds
The Narrow Band (NARROW) mode avoids the effects
of 2.4 GHz wireless remote controls that are used to
operate lighting equipment and other wireless devices.
You can use this mode and make adjustments to prevent
frequency overlaps in environments with multiple
wireless systems.
