The EM 550 G2 twin receiver
The EM 550 G2 twin receiver consists of two complete true diversity receivers
in a single 19” rack housing. The two receivers can be operated
independently from each other. The EM 550 G2 has an integrated antenna
splitter, enabling you to daisy-chain up to eight twin receivers.
The EM 550 G2 can be combined with transmitters of the ew 500 G2 series to
make high-quality state-of-the-art RF transmission systems for professional
applications. The transmitters and the twin receiver have a high level of
operational reliability and are extremly user-friendly. The excellent
transmission reliability is based on the use of
y further optimized PLL synthesizer and microprocessor technology,
y the HDX noise reduction system,
y the pilot tone squelch control,
y the true diversity technology (rack-mount receiver only),
y and the scan function for scanning the channel banks for free channels.
The channel bank system
The twin receiver is available in five UHF frequency ranges with 1,440
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

Each receiver of the EM 550 G2 has nine channel banks with up to 20
switchable channels each.
Each of the channels in the channel banks “1” to “8” has been factory-preset
to a receiving frequency (see enclosed frequency table). These receiving
frequencies cannot be changed but have been preset so that e.g. country-
specific regulations on frequency usage are taken into account.
