System Features
Superb Quality Wireless Transmission
The digital wireless microphone system transmits
high-quality 24-bit/48-kHz sampling digital audio
signals in a specific frequency bandwidth that
meets the wireless-communication regulations
of each country. Utilizing an original Sony
codec, based on Sony’s many years of
experience in engineering audio products, the
system delivers a wide dynamic range of more
than 106 dB, a wide frequency response of
20 Hz to 20 kHz, and an excellent system
latency of 3.6 ms.
Simultaneous Multi-channel Operation
The digital wireless microphone system allows
for large-scale multi-channel operations.
Thanks to the newly developed digital
modulator, the system realizes an
intermodulation-free, equally spaced channel
allocation. The digital wireless transmission
technology used in this system enables a
significant increase in the number of
simultaneous digital wireless systems in
comparison with current analog wireless
systems. For example, up to 12 channels of
simultaneous operation is possible on a 6-MHz
bandwidth TV channel in the USA.
This system also provides the option of using
existing WL-800 series channel plans. In this
configuration, the digital wireless system
reliably operates along with WL-800 series
analog wireless systems, without concern for
having analog and digital wireless systems
interfering with each other.
Stable and Secure Transmission
Incorporating a newly developed digital
modulator, the digital wireless microphone
system allows highly stable and secure wireless
transmission that is extremely tolerant to
interference waves. The system transmits
digitally modulated and encrypted data to
minimize the risk of interception, providing
highly secure transmission. For secure and
confidential communication, the system
provides two communication modes: peer-to-
peer mode and password mode. In peer-to-
peer mode, wireless communication between
a DWT-B01 transmitter and DWR-S01D receiver
can be established by exchanging an
encryption key that is generated by the
transmitter. In password mode, multiple
transmitters and receivers can be configured
by setting all devices with the same user-
designated password. In addition, this mode
supports broadcast communication, which
enables multiple receivers to receive audio
signals from one transmitter.
Pre-programmed Frequency Groups
To make it easy to choose the correct
frequencies for simultaneous multi-channel
operation, the optimum intermodulation-free
frequencies are stored on each DWR-S01D
receiver. These frequencies – all of which
have been calculated and tested – are
arranged in groups, with each group pre-
programmed to allow interference-free
operation. The digital wireless microphone
system operates within the following
frequency ranges:
