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 22 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: secure key mode and
password mode. In secure key mode, wireless
communication between a DWT-B01/DWT-P01
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:
