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

UHF frequency ranges with up to

3,000 receiving frequencies per frequency range:

Range Aw:

Range Gw:

Range Bw:

626 – 698

Range Cw:

718 – 790

Range Dw:

790 – 865

516 – 558 558 – 626

500

600

700

800

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 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 2000 IEM product page on our

website at www.sennheiser.com.

receiver.

CAUTION!

Danger of hearing damage!

If you switch the squelch off or adjust the squelch

threshold to a very low value, loud hissing noise can occur

in the receiver. The hissing noise can be loud enough to

cause hearing damage!

̈ Always make sure that the squelch is switched on.

Upon delivery, the SR 2000 IEM or SR 2050 IEM transmitter and the diver-

sity 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 intermodulation-

free 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).

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 transmit-

ters, 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 trans-

ferred 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 trans-

mitter 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 trans-

mission 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 inter-

modulation-free

If you are using frequencies from the frequency banks “U1” to

“U6”, it might be that the receiving frequencies are not intermod-

ulation-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

... 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 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 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.
