Short description
With the evolution wireless series ew 100, 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. Due to
further optimised PLL and microprocessor technology, the HDX noise
reduction system and true diversity technology (not pocket receivers), 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.
Range A:
Range B:
Range C:
Range D:
Range E:
518 – 550 MHz,
630 – 662 MHz,
740 – 772 MHz,
790 – 822 MHz,
838 – 870 MHz.
ew 100 transmitters and receivers are 4-channel switchable. Each transmitter
and receiver has 4 frequency memories to store up to 4 transmission/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 4 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 receiver (mains or pocket),
– a hand-held/pocket/plug-on transmitter and
– comes complete with all necessary accessories.

Important notes
Never open electronic devices! This must only be done by authorised
personnel and is all the more important for units connected to AC outlets. If
devices are opened by customers in breach of this instruction, the warranty
is voided.
Always disconnect the devices from the mains by removing the plug when
you wish to change connections or move the devices to a different place.
Keep the devices away from central heating radiators and electric heaters.
Never expose them to direct sunlight.
Use the devices in dry rooms only.
Use a damp cloth for cleaning the devices. Do not use any cleansing agents
or solvents.
Varnish or furniture polish may degrade the rubber feet of the transmitter.
Place the transmitter on a nonslip pad to avoid potential staining of furniture.

Mounting the rubber feet
To ensure that the receiver cannot slip on the surface on which it is placed,
four self-adhesive soft rubber feet are supplied. These feet are stuck into the
recesses on the bottom side of the receiver. (N.B.: Do not use these feet if
rackmounting the receiver).
!
Ensure that the recesses are clean and free from grease before fixing
the feet.
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 discolouration, since we don’t
know your furniture. You should therefore always place the receiver
on a non-slip pad.
Connecting the antennas
The EM 100 receiver can be used with either telescopic antennas (supplied)
or remote antennas (available as accessories).
*
The supplied telescopic antennas can be mounted quickly and easily to the
rear of the receiver 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 BNC sockets * and + at the
rear of the receiver. Pull the antennas out and align them upwards in
a V-shape.
If the receiver position is not the best antenna position for optimum reception,
you can use remote antennas. These are available as accessories.

Basic functions of the Sennheiser operating menu
A special feature of the Sennheiser evolution wireless series ew 100 is the
similar operation of transmitters and receivers. In stressfull situations, for
example on stage or during a live show or presentation, it is important that
the devices are easy to operate and that adjustments to the settings can be
made quickly and “without looking”. Therefore, the necessary operating steps
for each device are similar.
Important:
With the !/" buttons you can directly switch between the factorypreset frequencies (channels presets). The display starts flashing.
Your selection becomes effective immediately.
!
Press the SET button to enter the top menu level:
By briefly pressing SET again, you can change to the next menu.
After approx. one second, the selected menu appears on the display
and then the current setting of the menu is indicated.
"
Press the "/! buttons to adjust the settings of the selected menu:
The new setting starts flashing on the display. If you return to the
previous setting, the flashing stops.
Important:
New settings become effective immediately and will be
retained in memory on switch-off!
N.B.: When changing transmitter frequencies, care should be
taken to avoid causing interference to other channels/users.
In the “TUNE” menu, the "/! buttons feature a “fast search” function.
By briefly pressing the "/! buttons, the display jumps either forwards
or backwards to the next setting. If you hold down a button, the cycling
of the display is continously accelerted. If you release the button and

frequency setting as standard.
SenSit
Adjusting the sensitvity (transmitters only)
Close talking distances, speakers with loud voices or loud music sequences
may cause overmodulation in the transmission link, resulting in distortion.
In this case, the “PEAK” warning of the EM 100’s AF level display (as well as
the SK 100 transmitter’s yellow audio peak indication LED) will light up. If,
on the other hand, the sensitivity is adjusted too low, the transmission link
will be undermodulated, which would result in a signal with high background
noise.
The sensitivity has to be adjusted such that the “PEAK” warning of the
receiver’s AF level display only lights up during the loudest passages.
The following figures are a guide to the best settings:
Loud music/vocals:
Presentations:
Interviews:
70
-30 / -20 dB
-20 / -10 dB
-10 / 0 dB
!
Select the “SEnSit” menu by pressing the SET button until “SEnSit”
appears on the display; after a short pause the current sensitivity setting
is displayed.
!
With the !/" buttons you can now select a different setting. The
sensitivity can be adjusted in 10-dB steps from 0 to -30 dB. The new
setting starts flashing on the display and becomes effective immediately.
!
Press the SET button to return to the top menu level. The display
then switches back to the standard display.
SQELCH
SqELCH
Adjusting the squelch threshold (receivers only)
The Sennheiser evolution wireless series ew 100 receivers are equipped with
an adjustable squelch which eliminates annoying noise when the transmitters
are switched off. It also suppresses sudden noise when a transmitter leaves
the reception area and there is no longer sufficient transmitter power received
by the receiver.
!
Select the “SQELCH” menu by pressing the SET button until “SQELCH”
appears on the display; after a short pause the current squelch setting
is displayed.
!
With the !/" buttons you can now select a different setting. The
squelch can be switched off (0 dB) or adjusted in 5-dB steps from
5 dB to 40 dB. Selecting a smaller value reduces the squelch threshold,
selecting a higher value increases the squelch threshold. The new
setting starts flashing on the display. Set the squelch threshold – with
the transmitter switched off – to the lowest possible value that
suppresses hissing noise. If the squelch threshold is set too high, the
transmission range will be reduced.
Note:
With the transmitter switched off and the squelch threshold set to
“0 dB”, hissing noise will occur. With the EM 100 receiver, the “PEAK”
warning of AF level bargraph will light up.
!
Att
Press the SET button to return to the top menu level. The display
then switches back to the standard display.
Selecting the sensitivity range (SKP 100 only)
Condenser microphones require a different sensitivity range than dynamic
microphones. With the SKP 100 plug-on transmitter, you can switch the
sensitivity range by 20 dB.
!
Select the “Att” menu by pressing the SET button until “Att” appears
on the display; after a short pause the current setting – i.e. “Att off” or
“Att on” – is displayed.

Recommendations and tips
... for the ME 2 and ME 4 clip-on microphones
$ To reduce level variations to a minimum when the user turns his or her
head away from the microphone, attach the microphone as centrally as
possible.
$ To protect the microphone against excessive sweat/moisture, avoid direct
skin contact.
$ Attach the microphone carefully and conduct the cable such that noise
due to friction is avoided.
$ Always use the ME 4 directional microphone with a windshield and direct
the microphone towards the sound source (e.g. mouth).
... for the ME 3 headmic
$ Always use the microphone with a popshield and position the microphone
at the corner of the mouth.
$ You can vary the bass reproduction by increasing/decreasing the talking
distance.
$ Make sure that the sound inlet is directed towards the mouth. The sound
inlet is marked with a little dot.
... for the SK 100 pocket transmitter
$ Make sure that the antenna and the microphone cable do not cross.
$ The antenna should hang freely and be at least 1 cm away from the
body. The antenna must not be in direct contact with the skin.
$ For best results, make sure that the transmitter sensitivity is correctly
adjusted.
... for the SKM 100 hand-held transmitter
$ Hold the SKM 100 hand-held transmitter in the middle of the microphone
body. Holding it close to the sound inlet basket will influence the
microphone’s pick-up pattern, holding it at the lower part of the body
will reduce the transmitter’s range.
$ You can vary the bass reproduction by increasing/decreasing the talking
distance.
$ For best results, make sure that the transmitter sensitivity is correctly
adjusted.
... for the EK 100 receiver
$ The antenna should hang freely and be at least 1 cm away from the
body. The antenna must not be in direct contact with the skin. If the
receiver is mounted onto a camera, we recommend using the A 17 helical
antenna.
76
... for optimum reception
$ Transmission range depends to a large extent on location and can vary
from about 10 m to about 150 m. There should be a “free line of sight”
between transmitting and receiving antennas.
$ If, with the EM 100 receiver, reception conditions are unfavourable, you
should use two remote antennas which are connected via antenna cable
(# “Accessories”).
$ To avoid overmodulating the receiver, observe a minimum distance of
5 m between transmitting and receiving antennas.
$ Observe a minimum distance of 50 cm between receiving antennas and
metal objects (such as cross members or reinforced-concrete walls).
... for multi-channel operation
$ You cannot use all adjustable frequency combinations simultaneously. The
factory-preset frequencies (presets), however, are intermodulation-free. If you
wish to program new frequency combinations, please contact your local
Sennheiser agent who will provide you with information on the correct
frequency choice.
$ When using several transmitters simultaneously, interference can be avoided
by maintaining a minimum distance of 20 cm between two transmitters.
$ Use special accessories for multi-channel applications (# “Accessories”).

Care and maintenance
SKM 100 hand-held transmitter
The SKM 100’s sound inlet basket should be cleaned from time to time.
!
Unscrew the inlet basket (turn counter-clockwise) and remove it.
!
Use a damp cloth to clean the inlet basket from the inside and outside.
Note:
Do not use any cleasing agents or solvents. Do not touch the
microphone’s contacts.
!
Replace the inlet basket on the SKM 100 and screw it tight (taking
care not to loose the coloured identification ring).

Overview
Wireless transmission systems
With the evolution wireless series, Sennheiser puts an end to cable tangles
and enables complete freedom of movement at an affordable price.
The systems operate exclusively in the UHF band. UHF transmission is
extremely reliable and is far less prone to interference than the overcrowded
VHF band – harmonics from mains units, fluorescent tubes, refrigerators,
computers, etc. are virtually eliminated. Also indoor propagation of UHF
radio waves is better than VHF so that the RF power can be kept low – this
is also an advantage when using multi-channel systems. Finally, UHF
frequency ranges are being approved all over the world for radiomicrophone
usage – in some countries licence-free.
There are three transmitter versions: The hand-held transmitter is a
complete radiomicrophone in a single unit, the plug-on transmitter converts
your favourite dynamic wired microphone into a radiomicrophone, the
pocket transmitter can accept a wide range of inputs including: omnidirectional or cardioid “tie” microphones, head-worn microphone, guitar/
instrument direct input and auxiliary devices via the optional CL 2 line
input cable.
Fresh batteries ensure good transmission power during operation. Always
use alkaline batteries for best operation – a 9V PP3 battery has a much
longer operating time than a NiCd rechargeable battery (approx.
8 hours with a 9V PP3 or 1 hour with a rechargeable).
Correct adjustment of transmitter sensitivity is vital. Too high and you get
overmodulation and distortion, too low and you get undermodulation and a
noisy signal. Please set the sensitivity correctly for the microphone/usage
and check it before every performance to ensure best operation.
Sennheiser miniature clip-on microphones can be attached in various ways:
they can, for example, be attached to the hairline or to clothing (e.g. tie or
lapel). However it is fixed, please make sure that the microphone is protected
against sweat/moisture and make-up.
Interference such as distortion, hissing or “birdying” may occur if several
transmitters are used together and the frequencies have not been correctly
chosen. Sennheiser standard frequencies (as supplied) are all intermodulationfree. For other frequency sets please contact your local Sennheiser agent,
who will be able to provide you with information on correct frequency choice
and/or be able to calculate special frequency sets for you.

HDX noise reduction
Funkstrecke
Störsignale
Sender
Empfänger
Progress you can hear:
The evolution wireless Series is equipped with HDX, the new Sennheiser
noise reduction system that reduces RF interference. It increases the signalto-noise radio in wireless audio transmission to up to 110 dB.
HDX is a wideband compander system which compresses the audio signal in
the transmitter in a 2:1 ratio (related to dB) to lift it above the inherent noise
floor of the RF link. A 110 dB dynamic range signal is thus transmitted with
an effective dynamic range of only 55 dB, which is above the 60 dB noise
floor of the RF link. In the receiver the signal is expanded in an identical and
opposite way in a 1:2 ratio to restore the original signal, at the same time
reducing the RF noise to below the noise floor of the receiver. Giving a radio
link with a better signal-to-noise ratio than a CD.
HDX has been specially developed for high quality radiomicrophone systems.
Note:
Only transmitters and receivers that are equipped with HDX can work correctly
with each other. If non HDX equipment was mixed with HDX, the dynamic
range would be drastically reduced and the transmission would sound blunt
and flat. HDX is permanently active and cannot be switched off.

Diversity reception
The EM 100 receiver operates on the “true diversity” principle:
A receiving antenna receives not only the electromagnetic waves which reach
it by a direct path, but also the reflections of these waves which are created in
the room by walls, windows, ceilings and fittings. When these waves are
superimposed, destructive interference occurs, which can also be called “field
strength gaps”. Repositioning the receiving antenna can bring a solution,
provided the transmitter remains in its original position. With mobile
transmitters, however (which all radiomicrophones are ), the “field strength
gap” will then occur with a different transmitter position. These “field strength
gaps” can only be eliminated with true diversity receivers.
In true diversity, instead of one antenna and one receiver there are now two
antennas and two receiver sections. The antennas are spatially separated. By
means of a comparison circuit, the receiver section with the strongest RF
signal is always switched to the common AF output. The risk of the occurrence
of “field strength gaps” in both antennas at the same time is virtually
nonexistant.
The receiver display panel shows the active diversity section (I or II).
