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.
Utilising 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 realises 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 analogue wireless systems. For example, up to 16
channels of simultaneous operation is possible in an 8
MHz bandwidth TV channel in Europe.
This system also provides the option of using existing
WL-800 Series channel plans. In this configuration,
the digital wireless system reliably operates alongside
the WL-800 Series analogue wireless systems, without
concern for having analogue 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 extre-
mely tolerant to RF interference. The system transmits
digitally modulated and encrypted data to minimise
the risk of interception, providing highly secure
transmission. For secure and confidential commu-
nication, 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:
Metadata Transmission
In addition to audio signals, a variety of information
about the DWT-B01 transmitter – such as audio input
peak level, remaining battery capacity, low-cut filter
frequency and attenuator level – can be wirelessly
transmitted to the DWR-S01 receiver as metadata. This
allows users to monitor the status of the transmitter from
the DWR-S01D receiver, offering high operational
convenience.
