Short description

With the evolution wireless Series ew 300, Sennheiser offers musicians, video
and sound amateurs, reporters and local broadcasters high-quality state-of-
the-art RF transmission systems with a high level of operational reliability
and ease of use. Transmitters and receivers permit wireless transmission with
studio-quality sound. Due to further optimised PLL and microprocessor
technology, the HDX noise reduction system and true diversity technology,
these transmission systems ensure interference-free transmission and minimise
dropouts in the RF link.
The systems can be supplied in five frequency ranges within the UHF band.
Please note: Frequency usage is different for each country. Your Sennheiser
agent will have all the necessary details on the available legal frequencies for
your area.

ew 300 transmitters and receivers are 8-channel switchable. Each transmitter
and receiver has 8 frequency memories to store your selection out of 8 trans-
mission/receiving frequencies. The frequencies are selectable in 25-kHz steps,
giving a selection of 1280 frequencies within the preset 32 MHz frequency range.
Each system has 8 factory-preprogrammed frequencies, so that
– the systems are ready for immediate use after switch-on,
– several systems can be operated simultaneously on the factory-preset
transmission and receiving frequencies without causing intermodulation
interference. However, all frequency settings can be changed to your
individual needs, if required.
Each system consists of
– a mains receiver,
