The EK 2000 IEM diversity receiver The EK 2000 IEM diversity receiver This diversity receiver is part of the 2000 series. 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 are designed for monitoring applications and permit wireless transmission with studio-quality sound.
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.
Delivery includes The frequency banks “U1” to “U6” allow you to freely select and store receiving frequencies. It might be that these receiving frequencies are not intermodulation-free (see page 28).

Putting the diversity receiver into operation Putting the diversity receiver into operation 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 (see “Accessories” on page 33). 왘 Open the battery compartment by pushing the two catches 쐈 in the direction of the arrows and open the cover 쐅. 왘 Insert the two batteries or the accupack as shown above.
Putting the diversity receiver into operation Connecting the earphones 왘 Connect the earphones to the socket 쐇. The ground connection of the earphones cable serves as the antenna for the second diversity section. For details on the connector assignment, refer to the diagram on page 35. Attaching the diversity receiver to clothing You can use the belt clip 씊 to attach the diversity receiver to clothing (e.g. belt, waistband).
Putting the diversity receiver into operation To detach the belt clip: 왘 Lift one side of the belt clip as shown. 왘 Press down the belt clip at one fixing point and pull it out of the receiver housing. 왘 Repeat for the other side.
Using the diversity receiver Using the diversity receiver To establish a transmission link, proceed as follows: 1. Switch the diversity receiver on (see next section). 2. Switch a transmitter on (see the instruction manual of the transmitter). The transmission link is established and the receiver’s RF level display “RF” 햲 reacts. It is vital to observe the notes on frequency selection on page 28.
Using the diversity receiver To adjust the volume: CAUTION! Hearing damage due to high volumes! Listening at high volume levels for long periods can lead to permanent hearing defects. 왘 Set the volume to a low level before putting the earphones on. 왘 Do not continuously expose yourself to high volumes. 왘 Turn the volume control 쐃. Deactivating the lock mode temporarily You can activate or deactivate the automatic lock mode via the “Auto Lock” menu item (see page 24).
Using the diversity receiver Selecting a standard display ESC 왘 Press the ESC button to select a standard display. In stereo mode (see page 23), you can alternatively press the rocker button.

Using the operating menu Using the operating menu A special feature of the Sennheiser 2000 series is the consistent, intuitive menu structure of transmitters and receivers. As a result, adjustments to the settings can be made quickly – even in stressful situations, for example on stage or during a live show or presentation.

Using the operating menu Working with the operating menu If the lock mode is activated, you have to deactivate it In order to be able to work with the operating menu (see page 14). By way of example of the “Frequency Preset” menu, this section describes how to use the operating menu. Changing from a standard display to the operating menu SET 왘 Press the SET button. The current standard display is replaced by the main menu. The last selected menu item is displayed.
Using the operating menu Canceling an entry ESC 왘 Press the ESC button to cancel the entry. The current standard display appears on the display panel. To subsequently return to the last edited menu item: SET 왘 Press the SET button repeatedly until the last edited menu item appears.

Adjusting settings via the operating menu You can adjust the balance in 31 steps. In Focus mode (see next section) and when one of the standard displays is shown, you can also use the rocker button to adjust the balance. The mode of operation of the balance setting depends on the selected audio mode (see next section).
Adjusting settings via the operating menu Activating/deactivating the automatic lock mode – “Auto Lock” SET Menu Auto Lock Active Call up “Auto Lock” Auto Lock Active Select the desired setting Auto Lock Inactive Store the setting SET “Stored” The lock mode prevents that the balance is accidentally adjusted when the receiver is in Focus mode. In addition, the lock mode prevents that the diversity receiver is accidentally switched off or programed during operation.

SET 왘 Press the SET button to confirm the MHz section of the frequency.
Adjusting settings via the operating menu 왘 Press the rocker button to set the channel. 왘 Press the SET button to confirm the channel. SET The frequency (MHz section) is highlighted. 왘 Set the desired frequency (MHz and kHz section) as described in the previous chapter.
Adjusting settings via the operating menu 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. 왘 Set the limiter to a low level before putting the earphones on. 왘 Do not continuously expose yourself to high volumes.
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: 왘 Only use a transmitter and a diversity receiver from the same frequency range (see the type plates on the transmitter and the diversity receiver). 왘 Make sure that the desired frequencies are listed in the enclosed frequency information sheet.
Synchronizing a transmitter with the diversity receiver 왘 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.
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.
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.
