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
website at www.sennheiser.com.
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).

Areas of application
The receiver can be combined with the following transmitters:
Bodypack
Plug-on
transmitter
Radio microphone
transmitter
SK 100
SKM 100
SKP 100
These transmitters are available in the same UHF frequency ranges and
are equipped with the same frequency bank system with factory-preset
frequencies. An advantage of the factory-preset frequencies is that
• a transmission system is ready for immediate use after switch-on,
• several transmission systems can be operated simultaneously on the
preset frequencies without causing intermodulation interference.
Delivery includes
The packaging contains the following items:
1 EK 100 G3 diversity receiver
2 AA size batteries, 1.5 V
1 CA 2 camera adapter
1 CL 100 line cable
1 CL 1 line cable

Inserting the batteries/accupack
For powering the diversity receiver, you can either use two 1.5 V AA size
batteries or the rechargeable Sennheiser BA 2015 accupack or the DC 2
power adapter (see “Accessories” on page 23).
̈ Open the battery compartment by pushing the two catches µ in the

Synchronizing a transmitter with the diversity receiver – “Sync”
You can synchronize a suitable transmitter of the ew 100 G3 series with
the diversity receiver. During synchronization, the following parameters
are transferred to the transmitter:
• Current receiving frequency (“Frequency Preset”, see page 15)
• Current name set for the receiver (“Name”, see page 16)
• Current pilot tone setting of the receiver (“Pilot Tone”, see page 18)
To transfer these parameters:
̈ Switch the transmitter and the diversity receiver on.
̈ On the receiver, call up the “Sync” menu item.
“Sync” appears on the display panel of the receiver.
̈ Place the infra-red interface of the transmitter (see the instruction
manual of the transmitter) in front of the infra-red interface of the
receiver ¸.

The parameters are transferred to the transmitter. When the transfer
is completed, “ ” appears on the display panel of the diversity
receiver. The receiver then switches back to the current standard
display.
To cancel the transfer:

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.
