The EK 100 G3 diversity receiver  
The EK 100 G3 diversity receiver  
This diversity receiver is part of the evolution wireless series generation 3  
(ew G3). 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.  
Features of the evolution wireless 100 G3 series:  
• Optimized PLL synthesizer and microprocessor technology  
HDX noise reduction system  
• Adaptive diversity technology  
• Switching bandwidth of 42 MHz  
• Scan function (Easy Setup) for scanning the frequency banks for unused  
channels  
Adaptive diversity  
This diversity receiver uses the ground connection of the line cable as its  
second antenna to provide improved reception.  
The frequency bank system  
The diversity receiver is available in 6 UHF frequency ranges with  
1,680 receiving frequencies per frequency range:  
Range A:  
516 – 558  
Range G:  
566 – 608  
Range B:  
626 – 668  
Range C:  
734 – 776  
Range D:  
780 – 822  
Range E:  
823 – 865  
Each frequency range (A–E, G) offers 21 frequency banks with up to  
12 channels each:  
Channel 1 – frequency preset  
Channel 2 – frequency preset  
Frequency bank 1 ... 20  
Channel 12 – frequency preset  
Channel 1 – freely selectable frequency  
Channel 2 – freely selectable frequency  
Frequency bank U  
Channel 12 – freely selectable frequency  
Each of the channels in the frequency banks “1” to “20” has been factory-  
preset to a fixed receiving frequency (frequency preset). The factory-  
preset frequencies within one frequency bank are intermodulation-free.  
These frequencies cannot be changed.  
For an overview of the frequency presets, please refer to the supplied  
frequency information sheet. Updated versions of the frequency informa-  
tion sheet can be downloaded from the EK 100 G3 product page on our  
The frequency bank “U” allows you to freely select and store receiving  
frequencies. It might be that these receiving frequencies are not intermod-  
ulation-free (see page 19).

The transmitter adds an inaudible signal, known as the pilot tone, to the  
transmitted signal. The diversity receiver detects and evaluates the pilot  
tone. The pilot tone supports the diversity receiver’s squelch function, thus  
protecting against interference due to RF signals from other devices.

Synchronizing a transmitter with the diversity receiver  
Synchronizing a transmitter with the  
diversity receiver  
When synchronizing a transmitter with a diversity receiver, please  
observe the following:  
̈ Only use a transmitter and a diversity receiver from the same  
frequency range (see the type plates on the transmitter and  
the diversity receiver).  
̈ Make sure that the desired frequencies are listed in the  
enclosed frequency information sheet.  
You can also contact your Sennheiser partner who will be  
pleased to calculate intermodulation-free frequencies for you.  
̈ Make sure that the desired frequencies are approved and legal  
in your country and, if necessary, apply for an operating  
license.  
Upon delivery, transmitter and diversity receiver are synchronized with  
each other. If, however, you cannot establish a transmission link between  
transmitter and diversity receiver, you have to synchronize the channels of  
the devices:  
̈ Deactivate the RF signal on all transmitters (see the instruction manual  
of the transmitter).  
This prevents that, during the frequency scan, the channels used by  
switched-on transmitters are displayed as “used”.  
̈ With a diversity receiver, perform a frequency preset scan to scan the  
frequency banks for unused channels (“Scan New List”, see page 15).  
̈ Select a frequency bank and a channel on this diversity receiver  
(“Current List”, see page 15).  
If you want to set up a multi-channel system, select a frequency bank  
with a sufficient number of unused channels for all planned transmis-  
sion links.  
̈ Synchronize a transmitter with the diversity receiver (see page 14).  
The receiver’s frequency, name and pilot tone setting are transferred to  
the transmitter.  
OR:  
̈ Manually set the transmitter to the same frequency bank and channel  
that you set on the receiver.  
̈ Activate the RF signal on this transmitter.  
The transmission link is established.  
If you want to set up a multi-channel system:  
̈ Repeat the following 4 steps for each additional transmission link:  
– Perform a frequency preset scan with the next diversity receiver.  
– Select a channel from the same frequency bank as with the first  
diversity receiver.  
– Synchronize a transmitter with the diversity receiver.  
– Activate the RF signal on the transmitter.  
Using freely selectable receiving frequencies  
You can also freely select the receiving frequencies and store these  
frequencies in the frequency bank “U”.  
It might be that the freely selected frequencies are not inter-  
modulation-free  
If you use frequencies from the frequency bank “U”, it might be  
that the frequencies are not intermodulation-free.  
̈ Contact your Sennheiser partner who will be pleased to  
calculate intermodulation-free frequencies for you (see  
̈ Set each diversity receiver to the frequency bank “U”.

Synchronizing a transmitter with the diversity receiver  
̈ On one of the receivers, select a channel within this frequency bank and  
assign this channel one of the calculated receiving frequencies (see  
page 17).  
̈ Synchronize a transmitter with this receiver (see page 14).  
OR:  
̈ Manually set the transmitter to the same frequency bank and channel  
that you set on the receiver.  
̈ Repeat for the remaining transmitters and receivers as described  
above.

Cleaning the diversity receiver  
Cleaning the diversity receiver  
CAUTION!  
Liquids can damage the electronics of the receiver!  
Liquids entering the housing of the device can cause a  
short-circuit and damage the electronics.  
̈ Keep all liquids away from the receiver.  
̈ Do not use any solvents or cleansing agents.  
̈ Use a cloth to clean the diversity receiver from time to time.  
Recommendations and tips  
... for the diversity receiver  
• Make sure that the antenna and the line cable do not cross.  
• For best results, make sure that the transmitter sensitivity is correctly  
adjusted.  
... 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.  
• To avoid overloading the receiver, observe a minimum distance of 5 m  
between transmitting and receiving antennas.  
... for multi-channel operation  
• When operating a multi-channel system, you should only use the chan-  
nels within one frequency bank. Each of the frequency banks “1” to  
20” accommodates factory-preset frequencies which are intermodu-  
lation-free.  
• The frequency bank “U” allows you to freely select and store receiving  
frequencies (see page 16).  
• When using several transmitters simultaneously, interference can be  
avoided by maintaining a minimum distance of 20 cm between two  
transmitters.
