The EK 2000 IEM diversity receiver
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.

The frequency bank system

The receiver is available in 5 UHF frequency ranges with up to 3,000 receiving frequencies per frequency range:
Aw

:
Range 718 – 790
Range
:
Cw
Dw
790 – 865
:
Each frequency range (Aw–Dw, Gw) offers 26 frequency banks with up to 32 channels each:
Channel 1 – frequency preset
Channel 2 – frequency preset
Frequency bank 1... 20
Channel 32 – frequency preset
Channel 1 – freely selectable frequency
Channel 2 – freely selectable frequency
Frequency bank U1 ... U6
Channel 32 – 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 factory­preset 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 informa­tion sheet can be downloaded from the EK 2000 IEM product page on our website at www.sennheiser.com.

CAUTION! Danger of hearing damage due to a switched-off limiter!
The limiter limits the volume at the headphone output
PHONES and thus protects your hearing. With the limiter
switched off, the receiver is capable of producing high sound pressure levels. Prolonged exposure to high sound pressure levels can cause permanent hearing defects.
Set the limiter to a low level before putting the
earphones on.
Do not continuously expose yourself to high volumes.
You can adjust the limiter in 6-dB steps from –18 dB to –6 dB or switch it off (OFF).

Synchronizing a transmitter with the diversity receiver

Synchronizing a transmitter with the diversity receiver
When synchronizing the SR 2000 IEM or SR 2050 IEM 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.

Setting the transmitters to intermodulation-free channels (Easy Setup Sync)

Upon delivery, the SR 2000 IEM or SR 2050 IEM transmitter and the diver­sity receiver are synchronized with each other. If, however, you cannot establish a transmission link between transmitter and diversity receiver, you first have to use the diversity receiver to determine intermodulation­free channels and then transfer these channels to the transmitters. In doing so, no transmission links are established.
On all transmitters, call up the “Easy Setup” menu item.
Easy Setup Sync” appears on the display panels of the transmitters. The RF signals of the transmitters are deactivated. The transmitters await the transfer of a channel and a frequency bank via their infra-red interfaces.
With a diversity receiver, perform a frequency preset scan to scan the
frequency banks for unused channels (“Scan New List”, see page 21).
Select a frequency bank with a sufficient number of unused channels
and a channel on this receiver (“Current List”, see page 21).
28
Page 30
Synchronizing a transmitter with the diversity receiver
Start the Easy Setup Sync function by placing the infra-red interface of
this diversity receiver in front of the infra-red interfaces of all transmit­ters, one after the other. The diversity receiver transfers an unused channel from the selected frequency bank to the first transmitter and the next unused channel to the second transmitter and so on. As soon as a transfer is completed, the display panel of the transmitter displays the numbers of the trans­ferred frequency bank and channel.

Synchronizing transmitters with diversity receivers (Sync)

In a second step, you transfer the frequency bank and channel settings from the transmitters to other diversity receivers (synchronization) and thus establish the transmission links.
If you want to carry out synchronization at a later time:
Press the jog dial on the transmitter.
The frequency bank and the channel are stored. The transmitter’s RF signal is activated again. You can synchronize this transmitter with a diversity receiver at any time (see the instruction manual of the transmitter).
To carry out synchronization immediately:
Start the Sync function by placing the infra-red interface of the first
diversity receiver in front of the infra-red interface of the first trans­mitter while simultaneously pressing the SYNC button on the trans- mitter. The diversity receiver is set to the same frequency bank and channel as the transmitter. The transmitter’s RF signal is activated again. A trans­mission link is established between the first transmitter and the first diversity receiver.
Synchronize each of the remaining transmitters with one of the
remaining diversity receivers. Your multi-channel monitoring system is now ready for operation.
Instead of synchronizing, you can manually set the transmitters to the same frequency bank and channel that you set on the corresponding diversity receivers.

Cleaning the diversity receiver

Using freely selectable receiving frequencies

You can also freely select the receiving frequencies and store these frequencies in the frequency banks “U1” to “U6”.
It might be that the freely selected frequencies are not inter­modulation-free
If you are using frequencies from the frequency banks “U1” to “U6”, it might be that the receiving frequencies are not intermod­ulation-free.
Contact your Sennheiser partner who will be pleased to
calculate intermodulation-free frequencies for you (see www.sennheiser.com).
Set each diversity receiver to the same frequency bank (“U1” to “U6”).On one of the receivers, select a channel within this frequency bank and
assign this channel a receiving frequency (see page 25).
Synchronize a transmitter with this receiver (see the instruction
manual of the transmitter). 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
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

Recommendations and tips
... for the diversity receiver
• Make sure that the antenna and the earphones 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 chan­nels within one frequency bank. Each of the frequency banks “1” to “20” accommodates factory-preset frequencies which are intermodu­lation-free.
• The frequency banks “U1” to “U6” allow you to freely select and store receiving frequencies (see page 24).
• When using several transmitters simultaneously, interference can be avoided by maintaining a minimum distance of 20 cm between two transmitters.
