The SK 500 G2 bodypack
transmitter
The SK 500 G2 bodypack transmitter 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 studio-quality 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 and the pilot tone squelch control.
The channel bank system
The transmitter is available in five UHF frequency ranges
with 1440 transmission 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:
Range B:
Range C:
Range D:
Range E:
518 to 554 MHz
626 to 662 MHz
740 to 776 MHz
786 to 822 MHz
830 to 866 MHz
The transmitter 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 transmission frequency (see
enclosed frequency table). These transmission 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
frequencies that are freely selectable.

Areas of application
The transmitter can be combined with receivers of the
ew 500 G2 series (EM 500 G2 rack-mount receiver or
EK 500 G2 bodypack receiver). The receivers 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 receiver and a microphone or an
instrument cable, the transmitter is suitable for the
following areas of applications:

displays, the transmission of transmitter battery
status information to the rack-mount receivers and
the switch-off thresholds at the end of the operating
time are corrected correspondingly. Due to the
missing sensor, individual rechargeable battery cells
will not be identified as accupacks.
y The monitoring of the accupack temperature during
charging in the L 2015 charger.
y The prevention of improper charging of inserted
primary cells (batteries). Due to the missing sensor,
individual rechargeable battery cells will also not be
charged in the L 2015 charger.
Connecting the microphone/line cable
The microphone/line input is designed for the connection of
both condenser microphones and instruments (e.g.
guitars). DC powering of the condenser microphones is via
the microphone/line input.

Positioning the microphones
The ME
3
and ME
4
microphones are directional
microphones, i.e. their sound inlet should always be
directed towards the sound source (e.g. mouth).
The ME 2 with omni-directional pick-up pattern picks up
sound equally from all directions. It is the best choice if
movements of the speaker’s head have to be compensated
for. However, it should be attached as close as possible to
the sound source.
Adjust the sensitivity correctly for all microphones/usages
(see “Adjusting the sensitivity” on page 53).
Attaching the transmitter to clothing
The transmitter is attached to clothing (e.g. belt,
waistband) with the supplied belt clip.
The clip is detachable so that you can also attach the
transmitter with the antenna pointing downwards. To do
so, withdraw the clip from its fixing points and attach it the
other way round.
The supplied BPP 1 bodypack pouch helps to protect the
transmitter against moisture.

Adjustment tips for the
operating menu
Switching between channel banks – BANK
Via the “BANK” menu, you can switch between the
transmitter’s nine channel banks. Each of the channel
banks “1” to “8” has up to 20 switchable channels that are
factory-preset to a transmission frequency (see “The
channel bank system” on page 36). The channel bank “U”
(user bank) has up to 20 switchable channels to store your
selection out of 1440 transmission frequencies that are
freely selectable within the preset frequency range.
When switching from one channel bank to another, the
channel with the lowest channel number is automatically
displayed.
Switching between the channels – CHAN
Via the “CHAN” menu, you can switch between the different
channels in a channel bank. When switching between the
channels, please observe the following:
Always set the transmitter and the receiver of a
transmission link to the same channel.
Multi-channel operation
Combined with ew 500 G2 receivers, the transmitter can
form transmission links that can be used in multi-channel
systems. For multi-channel operation, only use the free
channels in a channel bank.
Before putting the transmission links into operation, we
recommend performing an auto scan (see operating
manual of the receiver).
Selecting the frequencies to be stored
in the channel bank “U” – TUNE
Via the “TUNE” menu, you can select the frequencies to be
stored in the channel bank “U” (user bank).
When you have selected one of the channel banks “1” to “8”
and then select the “TUNE” menu, the transmitter auto-
matically switches to channel 01 of the channel bank “U”.
In this case, “U.01” briefly appears on the display.

ew500_SK.book Seite 53 Dienstag, 4. November 2003 4:02 16
̈ Use the ̆/̄ rocker button to select the desired
transmission frequency. Transmission frequencies are
tunable in 25-kHz steps within a switching bandwidth
of 36 MHz max. For intermodulation-free frequencies,
please refer to the enclosed frequency table.
Adjusting the sensitivity – SENSIT
Via the “SENSIT” menu, you can adjust the transmitter’s
input sensitivity.
The input sensitivity is adjusted too high when close talking
distances, speakers with loud voices or loud music passages
cause overmodulation in the transmission link. In this case,
the transmitter’s yellow LED (AF PEAK) ꢁ will light up and
the level display for the audio signal “AF” ቩ shows full
deflection for the duration of the overmodulation.
¿
ቩ
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 is correctly adjusted when the level display
for audio signal “AF” ቩ shows full deflection only during
the loudest passages.
Note:
For monitoring the adjusted sensitivity, the
transmitter’s level display for audio signal “AF” always
indicates the audio level – even if the transmitter is
muted.
The following figures are a guide to the best settings:
y Loud music/vocals:
y Presentations:
–30 to –20 dB
–20 to –10 dB
–10 to 0 dB
y Interviews:
y Musical instruments:
y electric guitars with
single coil pickups:
–10 bis 0 dB
y electric guitars with
humbucker pickups:
–20 to –10 dB
y guitars with active
electronics (active pickups,
active EQs, piezo pickups):
–30 to –20 dB

remains unchanged. After the reset, the transmitter is
restarted and the standard display is shown on the display
panel.
Activating/deactivating the pilot tone
transmission – PILOT
Via the “PILOT” menu, you can activate or deactivate the
pilot tone transmisssion.
The pilot tone supports the receiver’s squelch function
(Squelch) and protects against interference due to RF
signals from other units. The transmitter adds an inaudible
signal, known as the pilot tone, to the transmitted signal.
The receiver detects and evaluates the pilot tone.
Transmitters of the ew 500 series (first generation) do not
transmit a pilot tone and the receivers of the ew 500 series
(first generation) cannot evaluate the pilot tone.
Nevertheless, you can combine the transmitter with a
receiver of the first generation by observing the following:
y With the ew 500 G2 transmitter and an ew 500 G2
receiver:
Activate the pilot tone function with both transmitter
and receiver.
y With the ew 500 G2 transmitter and an ew 500 receiver
or vice versa:
Deactivate the pilot tone function with the ew 500 G2
transmitter or receiver.
Activating/deactivating the lock mode – LOCK
Via the “LOCK” menu, you can activate or deactivate the
lock mode.
The lock mode prevents that the transmitter is accidentally
programmed or switched off during operation. The lock
mode icon ቨ on the display indicates that the lock mode is
activated.
ቨ
To deactivate the lock mode, first press the SET button and
then press the ̆/̄ rocker button to select “LOC.OFF”. If
you confirm your selection by pressing the SET button, the
buttons can be operated as usual.
Exiting the operating menu – EXIT
Via the “EXIT” menu, you can exit the operating menu and
return to the standard display.

Recommendations and tips
... for the ME 2 and ME 4 clip-on microphones
y 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.
y To protect the microphone against excessive sweat/
moisture, avoid direct skin contact.
y Attach the microphone carefully and conduct the cable so
that noise due to friction is avoided.
y 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
y Always use the microphone with a popshield and position
the microphone at the corner of the mouth.
y You can vary the bass reproduction by increasing/
decreasing the talking distance.
y Make sure that the sound inlet is directed towards the
mouth. The sound inlet is marked with a little dot.
... for the bodypack transmitter
y Make sure that the antenna and the microphone cable do
not cross.
y 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.
y For best results, make sure that the transmitter
sensitivity is correctly adjusted.
... for optimum reception
y 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.
y To avoid overmodulating the receiver, observe
a
minimum distance of 5 m between transmitting and
receiving antennas.
... for multi-channel operation
y For multi-channel operation, you can only use the
channels in a channel bank. Each of the channel banks “1”
to “8” accommodates up to 20 factory-preset
frequencies which are intermodulation-free. For
alternative frequency combinations, please refer to the
enclosed frequency table. The freely selectable
frequencies can be selected via the “TUNE” menu and can
be stored in the channel bank “U”.
y When using several transmitters simultaneously,
interference can be avoided by maintaining a minimum
distance of 20 cm between two transmitters.
