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
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 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
Range E:
830 to 866 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.
The channel bank "U" (user bank) allows you to store your selection out of
1,440 receiving frequencies that are freely selectable within the preset
frequency range.

Safety instructions
No user serviceable parts inside! Never open the receiver, otherwise you can
receive an electric shock. If units are opened by customers in breach ofthis
instruction, the warranty becomes null and void.
The receiver is a Class I device, it must only be connected to properly
grounded power outlets.
Use the receiver in dry rooms only. Never expose it to water (eg: never place
it in a position where it could be subjected to water splashes). Do not place
any objects containing liquids on the top of the unit.
Keep the receiver away from direct sunlight, central heating radiators, electric
heaters and similar sources of heat. Ensure sufficient ventilation, especially
when it is mounted into a 19'' rack.
Use a damp cloth for cleaning the unit. Do not use any cleansing agents or
solvents.
Attention! High Volume!
This is a professional transmission system. Commercial use is subject to the
rules and regulations of the trade association responsible. Sennheiser, as the
manufacturer, is therefore obliged to expressly point out possible health risks
arising from use.
The sound pressure at the headphone outputs of the twin receiver may
exceed 85 dB(A). 85 dB(A) is the sound pressure corresponding to the
maximum permissible volume which is by law (in some countries) allowed to
affect your hearing for the duration of a working day. It is used as a basis
according to the specifications of industrial medicine. Higher volumes or
longer durations can damage your hearing. At higher volumes, the duration
must be shortened in order to prevent damage. The following are sure signs
that you have been subjected to excessive noise for too long a time:
You can hear ringing or whistling sounds in your ears.
You have the impression (even for a short time only) that you can no longer
hear high notes.
Delivery includes
The packaging contains the following items:
1 EM 550 G2 twin receiver
