The evolution wireless series ew 300 G2
With the evolution wireless series ew 300 G2, Sennheiser offers musicians, video
and sound amateurs 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. The excellent
transmission reliability of the ew 300 G2 series is based on the use of
further optimized PLL synthesizer and microprocessor technology,
the HDX noise reduction system,
the pilot tone squelch control,
the true diversity technology (rack-mount receiver only),
and the scan function for scanning the channel banks for free channels.
The channel bank system
The ew 300 G2 systems are available in five UHF frequency ranges with 1440
transmission/receiving frequencies per frequency range. 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.
Range A:
518 to 554 MHz
Range B:
626 to 662 MHz
Range C:
740 to 776 MHz
Range D:
786 to 822 MHz
Range E:
830 to 866 MHz
Transmitters and receivers have nine channel banks with eight switchable
channels each.
The channel banks "1" to "8" have eight switchable channels that are
factory-preset to a transmission/receiving frequency (see enclosed
frequency table). These transmission/receiving frequencies cannot be
changed but have been preset so that e.g. country-specific regulations on
frequency usage are taken into account. The channel bank "U" (user bank)
has eight switchable channels to store your selection out of 1440
transmission/receiving frequencies that are freely selectable within the
preset frequency range.
An advantage of the factory-preset frequencies is that
the systems are ready for immediate use after switch-on,
several systems can be operated simultaneously on the preset channels
without causing intermodulation interference.
