WiNRADiO receivers have been used to assist in stage productions by sound engineers of numerous famous performers and groups, famous personalities, major world venues, events and performances.

With the WR-G33WSM model, WiNRADiO introduces a high-performance low-cost receiver and spectrum analyzer specially developed for sound engineers and performers who work with wireless microphones and other wireless audio devices.

The receiver contains a number of specialist features tailored to audio engineering. Its wide frequency range covers all standard wireless microphone and other VHF/UHF frequencies used in stage production, including the FM broadcast band and point-to-point communications.

Highly sensitive, easy to interface with standard laptops and PCs and optimized to work with short VHF/UHF antennas, the receiver is also simple to install and intuitive to use.

Its fast scanning facilities make it possible to map the radio spectrum environment of a particular location, quickly determine available frequencies and allocate wireless microphones to the available channels. The entire spectrum environment of each venue can be saved and recalled later, to save time during the next visit.

Each performer's microphone signal peak is clearly visible in the scanned spectrum, and can be marked with a user-defined description. All this information, too, can be saved.

The receiver comes in a small enclosure which connects to an IBM-compatible PC (desktop or laptop) via the supplied USB cable. An external antenna connects to the receiver.

The WiNRADiO G33WSM: A ground-breaking audio engineering tool that will surely surprise you.

The WR-G33WSM user interface displays a mix of standard receiver controls such as a tuning knob, frequency display and signal strength meter, supplemented by a number of innovative facilities specially designed for wireless audio engineering.

The WR-G33WSM is the first Software Defined Radio specifically designed for audio engineering and stage production applications.

A Software Defined Radio (SDR) is one where most of the radio signal processing is performed in software, using digital signal processing methods, rather than using traditional hardware parts, resistors, capacitors, diodes, etc. The received signal is digitized early in the signal processing chain, and any further processing, demodulation and decoding of the digitized signal is then performed entirely in software.

There are many advantages to this approach, especially the flexibility of demodulation modes - new modes can be added easily by simply upgrading software.

And finally, the G33WSM receiver offers far more features and facilities than a conventional receiver. For example, the real-time spectrum analyzer with both linear and logarithmic scale, variable IF (intermediate frequency) filter and audio recording are some of the many features which were previously unavailable on a conventional VHF/UHF receiver, in particular at such an affordable price level.
