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:

Inserting and charging the accupack  
The transmitter can also be powered via the rechargeable  
Sennheiser BA 2015 accupack. Insert the accupack into the  
battery compartment as described above.  
The transmitter has two charging contacts and a sensing  
contact on its short sides. The accupack can be recharged  
while remaining in the transmitter. Insert the transmitter  
into the L 2015 charger (see operating manual of the  
L 2015 charger).  
Note:  
For accupack operation of the transmitter, only use the  
BA 2015 accupack in order to ensure optimum  
operational reliability. For charging the accupack, only  
use the L 2015 charger. Both the accupack and the  
charger are available as accessories.  
The accupack is fitted with an integrated sensor which is  
– via a third contact – monitored by the electronics of  
the transmitter and the charger. The sensor is necessary  
for the following control purposes:

y The taking into account of the different voltage  
characteristics of primary cells (batteries) and  
accupacks. The battery status indications on the  
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

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  
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  
automatically switches to channel 01 of the channel bank  
“U”.  
In this case, “U.01” briefly appears on the display.

̈ 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.  
¿
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” 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:

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 on the display indicates that the lock mode is  
activated.  
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.
