Improved Audio Quality

Sony’s DWX digital wireless offers superb audio quality (24 bit 48 KHz digital audio)

A majority of high-end vocal performance wireless microphone systems in use today rely on the use of

conventional analog transmission technology called FM Modulation. These analog wireless systems

offer sound characteristics similar the sound of FM radio.

The sound quality of analog wireless has somewhat improved over the years by adding a sound

processing technique called a compander. The use of the compander has improved audio dynamic

range performance in analog wireless systems; however, further improvements in sound quality aren’t

likely.

For vocal performance, the use of analog wireless compromises sound quality and it is difficult to fully

reproduce all of the subtle nuances of a vocal performance using analog wireless. The use of Sony digital

wireless overcomes this limitation by eliminating the use of a compander system and by providing high

quality digital sound.

Capturing live performances for the purpose of distributing high quality audio and video musical

performances often requires extra efforts applied (during audio post production) to correct deficiencies

caused by the use of analog wireless microphones. Occasionally, vocals recorded during live

performance need to be replaced (by overdubbing vocals in a studio afterwards) to improve sound

quality. When this occurs, correcting sound quality problems can be costly and time consuming. Using

Sony’s digital wireless greatly reduces the need to overdub vocals in studio afterwards.

Sony offers two choices of DWX high-quality handheld microphones (Dynamic and Condenser)

Both microphones offer extremely directional characteristics, reducing the potential for audio feedback

occurring when stage monitors are used during live performance. The choice of both dynamic and

condenser microphones allows the vocalist to select the microphone that best suits their vocal style.

DWX Operational Benefits

Transmitter allows entering an alphanumeric name that is displayed on both the TX and RX

Especially useful in large multichannel systems, transmitter naming allows quick identification of each

wireless microphone. Each handheld microphone/transmitter contains a USB port that allows

connection of a standard USB keyboard (during system set-up) for entering each transmitter’s name.

The TX name is permanently stored in each TX and this transmitter name is transmitted (along with

digital audio) as metadata.

Unique encryption feature supports ultra-secure transmission

Enabling encryption insures audio signal won’t be intercepted and used for unauthorized purposes.

Easy-to-see OLED (Organic Light-Emitting Diode) displays

Each receiver includes large independent OLED displays and controls for managing two channel wireless

microphones. Each handheld microphone also includes an internal OLED (hidden) display that can be

accessed by unscrewing the body of the handheld microphone for changing TX menu settings.

Receiver includes clear channel scan allowing quick scanning to locate a free frequency

Fast and simple scanning allows finding an unoccupied RF frequency and the option to change the

system (RX and TX) to operate on the newly found frequency very quickly. If the wireless system

experiences interference during use, activating clear channel scan and selecting a new frequency can be

completed quickly. This function can be operated from the receiver front panel or from the PC remote

control software (remotely).

Innovative wireless remote control of the transmitter from the receiver

Menu settings on each handheld microphone/transmitter can be remotely adjusted without having to

access the handheld microphone. This means that audio attenuator level, low cut filter can be adjusted

remotely and system RF frequency selection can be changed without accessing the transmitter.

PC Control Software

Each receiver contains an Ethernet port that can be connected with a network switch to support

networked monitoring and control functions. In this case, all transmitter and receiver settings can be

remotely monitored and controlled by the PC software. Multiple PC’s running the supplied application

can be connected to the remote control network allowing control of system settings from multiple PC’s.
