The EM 500 G2 rack-mount receiver
The EM 500 G2 rack-mount receiver is part of the evolution wireless series
ew 500 G2. With this series, Sennheiser offers 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 studioquality sound. The excellent transmission reliability of the ew 500 G2 series
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 EM 500 G2 receiver is available in five UHF frequency ranges with 1440
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
The receiver has nine channel banks with up to 20 switchable channels each.
channel 1
channel 2
channel bank 1...8
channel 20

channel 2
channel bank U
channel 20

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. countryspecific regulations on frequency usage are taken into account.
The channel bank “U” (user bank) allows you to store your selection out of
1440 receiving frequencies that are freely selectable within the preset
frequency range.

Safety instructions
Never open an electronic unit! If units are opened by customers in breach of
this instruction, the warranty becomes null and void.
Keep the unit away from central heating radiators and electric heaters. Never
expose it to direct sunlight.
Use the unit in dry rooms only.
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.
This system is capable of producing sound pressure exceeding 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:
y You can hear ringing or whistling sounds in your ears.
y You have the impression (even for a short time only) that you can no longer
hear high notes.

Areas of application
The EM 500 G2 receiver can be combined with transmitters of the ew 500 G2
series (SK 500 G2 bodypack transmitter, SKM 500 G2 radiomicrophone or
SKP 500 G2 plug-on transmitter). The transmitters are available in the same
five UHF frequency ranges and are equipped with the same channel bank
system with factory-preset frequencies. An advantage of the factory-preset
frequencies is that
y a transmission system is ready for immediate use after switch-on,
y several transmission systems can be operated simultaneously on the
preset frequencies without causing intermodulation interference.
Together with a matching transmitter and a microphone, the receiver is
suitable for the following areas of applications:

separately)
SK 500 G2 y Theater

Indications and displays
When used together with an ew 500 G2 transmitter, the receiver provides
information on its operating states and those of the received transmitter
(remote displays).
Indications and displays of the receiver
“PILOT” display
The “PILOT” display appears on the display panel when the pilot tone
evaluation is activated (see “Activating/deactivating the pilot tone
evaluation” on page 23).
Diversity display
The EM 500 G2 receiver operates on the true diversity principle (see
“Diversity reception” on page 28).
The diversity display indicates whether diversity section I (i.e. antenna 1)
or diversity section II (i.e. antenna 2) is active.
Button backlighting
During standby operation, the ON button is backlit in red. When the
receiver is switched on, the SET button and the / button are
additionally backlit in green.
Remote displays of an ew 500 G2 transmitter
Transmitter battery status indication
The 4-step transmitter battery status display on the receiver display panel
provides information on the transmitter’s remaining battery/accupack
capacity:
3 segments: capacity approx. 100 %
2 segments: capacity approx. 70 %
1 segment: capacity approx. 30 %
Battery icon flashing LOW BAT
In addition, the text “LOW BAT” (backlit in red)
flashes in alternation with the standard display.
8
“MUTE” display
The “MUTE” display appears on the display panel and the backlighting of
the standard display switches from green to red. In addition, the text “MUTE”
flashes in alternation with the standard display when
y the RF signal of the received transmitter is too weak,
y the received transmitter has been muted (with the pilot tone transmission
or evaluation activated).
Modulation display
The level display for audio signal “AF” shows the modulation of the received
transmitter.
When the transmitter’s audio input level is excessively high, the receiver’s
level display for audio signal “AF” shows full deflection.
When the transmitter is overmodulated frequently or for an extended period
of time, the text “PEAK” (backlit in red) flashes in alternation with the
standard display.

Preparing the receiver for use
Mounting the receiver feet
To ensure that the receiver cannot slip on the surface on which it is placed,
four self-adhesive soft rubber feet are supplied.
Ensure that the base of the receiver is clean and free from grease before
mounting the rubber feet.
Fix the rubber feet to the base of the receiver by peeling of the safety
paper and fitting them as shown in the digram on the left.
Attention!
Some furniture surfaces have been treated with varnish, polish or synthetics which might cause stains when they come into contact with other
synthetics. Despite a thorough testing of the synthetics used by us, we
cannot rule out the possibility of staining.
Connecting the antennas
The supplied telescopic antennas can be mounted quickly and easily and are
suitable for all applications where – good reception conditions provided – a
wireless transmission system is to be used without a large amount of
installation work.
Connect the telescopic antennas to the BNC sockets and at the
rear of the receiver.
Pull the telescopic antennas out and align the upwards in a V-shape.
Use remote antennas (available as accessories) when the receiver position is
not the best antenna position for optimum reception.
Connecting the mains unit
The receiver is powered via a mains unit.
Pass the cable through the cable grip .
Insert the DC connector on the mains cable into the DC socket .
