Digital Wireless System

The DWS2400 is the worlds first digital wireless system operating in the 2.4GHz range,

leading the way to the future of wireless transmission. Digital Wireless brings a new

dimension to the sound, dynamics and the noise ratio of wireless systems, avoiding the

limitations of analog systems.

Analog Wireless Systems always require a compander system to reduce the signal to

noise ratio to an useable level, meaning the signal is being compressed in the transmitter

and on the other side decompressed in the receiver. This method is required in every

analog wireless system. Unfortunately this limits the range of dynamic, in particular for

guitarists and bass players. However, with the digital wireless transmission the analog

technology will become outdated. The signal is converted through a high profile Delta

Sigma 20bit AD-Converter in the transmitter into digital data. Those data packages are

sent to the receiver to be converted back into an analog signal. This technology allows a

natural, full dynamic range. The data transmission also avoids also the frequency

modulation of an analog system. The result is a crystal clear sound without hissing.

The frequency range of a DWS2400 System means CD-Quality. The sampling rate of

44.1KHz gives an unbelievable range of 20Hz to 22KHz. Analog systems only manage a

range of 50Hz up to 15KHz due to the method of construction.

The DWS 2400 works on a 2.4GHz basis in the upper UHF range, allowing an enormous

amount of broadband data transmission. This method requires a special antenna

technique, which was implemented in the 2400 R receiver, the so-called PATCH - Antenna,

that is mounted on top of the receiver so that it can be flipped up easily.

The DWS2400 System works on the principle of true diversity technology, meaning two

separate receiver channels work independently, and are controlled by intelligent

electronics to always process the best incoming signal allowing for an absolutely reliable

system!

The known latency (delay) of digital signal processing is an outstanding 2 ms and

therefore not noticeable for the user.
