Product Description

The Sony DWX N series digital wireless system, which consists of the DWT-B01N body-pack transmitter, DWM-02N microphone and DWR-R02DN receiver, delivers superb-quality wireless transmission of 24-bit digital audio. Thanks to its improved codec and new hardware, it can provide higher sound quality with lower audio latency, up to 24Bit/96kHz.

The DWX N series works with Sony control software Wireless Studio 4.2 or later for PC and Wireless Studio Mobile for smartphones* to give users flexible control of the system. Remote control of up to 82 transmitters can be achieved using the Cross Remote™ function combined with the RMU-01 remote control unit.

NOTE: This model is available in multiple versions to support the widest possible range of operating frequencies. Please refer to product specifications for more information.

What sets the Sony DWX N series apart?

The DWX N series boasts three Sony codec modes designed for wide variety of applications:

  • MODE1 for compatibility with DWX series applications
  • MODE2 with higher quality sound and low latency ideal for theatre, tour and broadcast applications
  • MODE3 with more reliable RF transmission ideal for speech applications.

Low audio latency and high quality sound

MODE2 provides higher quality sound with a 96kHz sampling rate and very low audio latency of 1.5 msec**.

More reliable RF transmissions expands the operation range

MODE3 operation optimised for reliable transmission by preventing drop out by interference with additional error correction

Compatibility with DWX series

MODE1 operation provides the same high quality, reliability and audio latency as the previous DWX series version.

Smartphone control*

Wireless Studio Mobile software gives users remote control of the DWX N series system via a smartphone.

Notes

* Wireless Studio Mobile supported OS: iOS Ver.8.0 or later and Android Ver.4.1 or later. Operation is not guaranteed on all smartphones.

Sony DWT-B01N Features

  • Three codec modes for more reliable RF transmissions and higher quality sound

    The Sony codec has been improved to provide three codec modes optimised for a wider variety of applications. MODE1 provides compatibility with DWX series applications, with the same audio latency of 3.4 msec. MODE2 provides higher quality sound with a 96kHz sampling rate A/D converter and very low audio latency of 1.5 msec**. MODE3 provides more reliable RF transmission with an audio latency of 4.0 msec***

  • Superb quality wireless transmission and reception

    The digital wireless microphone system transmits and receives high-quality 24-bit digital audio in a specific frequency bandwidth that meets the Wireless Communication Regulations of each country. Utilising the Sony original codec based on Sony’s 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 22kHz, and an excellent transient response.

  • Stable and secure transmission and reception

    Incorporating the improved digital modulator, the digital wireless microphone system allows highly stable wireless transmission that is extremely tolerant to unwanted interference.
In addition, the system transmits and receives digitally modulated and encrypted data to minimize the risk of interception, providing highly secure transmission and reception.

  • Simultaneous multi-channel operation

    The digital wireless microphone system allows for large-scale multi-channel operations. Thanks to the 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 operations in comparison with current analogue wireless systems. For example, up to16 channels of simultaneous operation is possible in an 8-MHz operating band.

  • Low noise head amplifier

    Low noise head amplifier achieves -128dBu noise floor.

  • Flexible audio input control

    48dB at 3dB steps audio attenuation supported. Line / Microphone input supported. Transmitter audio attenuation can be controlled from receiver side using Sony wireless remote control system.

  • Flexible battery options

    The DWT-B01N is able to accept a variety of AA type battery, such as Alkaline, Lithium, NiMH etc.

  • Selectable output power

    Output power selectable between 1/10/50 mW. Chose the minimum power necessary for a venue, lengthening battery life, and reducing the already low possibility of interference. Allows the microphone to work effectively in a very wide range of venues.

  • High quality OLED display

    A variety of information is obtained at a glance from the high quality OLED display panel, such as the reception channel, Audio and RF signal status, user name, user group, Lock etc.

  • Wireless remote control

    Remote control of transmitter functions from the receiver can be achieved using the Cross Remote™ function and RMU-01 remote control unit.

  • Smartphone control using Wireless Studio Mobile software

    The DWX N series works with Sony control software Wireless Studio 4.2 or later for PC and Wireless Studio Mobile for smartphones* to give users flexible control of the system.

  • Notes

    * Wireless Studio Mobile supported OS: iOS Ver.8.0 or later and Android Ver.4.1 or later.. Operation is not guaranteed on all smartphones.
