The EK 3241 true diversity receiver The EK 3241 is a miniature true diversity receiver designed for use with digital ENG camcorders. It can be inserted into the slot-in facility of e.g. Ikegami, Panasonic, Sony or Thomson camcorders without any additional connecting cables being required. The GA 3041-C slot-in housing is used for externally attaching the receiver to camcorders without a slot-in facility.

Putting the receiver into operation Connecting the antennas The receiver is supplied with two antennas which are necessary for true diversity operation (see “Diversity reception” on page 22). Connect the antennas to the antenna sockets and . Screw the antennas tight. Mounting the receiver into a camcorder The receiver can be inserted into the slot-in facility of most professional camcorders. Suitable mounting kits are available as accessories from your Sennheiser partner.
Secure the mounting frame to the camcorder housing using four screws . Insert the receiver into the slot-in facility until the 25-pin connector securely connects. Screw the receiver (from above) to the mounting frame.

The operating menu has three modes: y Display mode In display mode, you can display the current menu settings one after the other – even when the lock mode is activated. y Selection mode In selection mode, you can select the menu whose setting you want to change. To change to the selection mode, the lock mode must be deactivated.
Displaying the menu settings in display mode In display mode, and with the lock mode activated, you can display the current menu settings one after the other (see “Overview of the operating menu” on page 14). ON SET Press the button or the button to display the menu settings. If you press the button repeatedly, all menu settings are displayed one after the other. After approx. 15 seconds, the display returns to the standard display.
The following menus are available: Menu Function of the menu PHonE Adjusting the headphone volume* CHAn Selecting a channel tunE Setting receiving frequencies for the channel bank “U” (variable bank) SquELH Adjusting the squelch threshold Auto Activating/deactivating the automatic receiver switch-on/off via the camcorder dISP Selecting the standard display rESEt Loading the factory-preset default settings Loc Activating/deactivating the lock mode ESc Exiting the selection mode and returni
Storing a setting ON SET Press the SET button to permanently store a setting. “StorEd” appears on the display panel, indicating that the setting has been stored. The display then returns to selection mode. Cancelling an entry ON SET Select the “ESc” menu to exit the selection mode and to return to the standard display.
Overview of the operating menu Deactivate the lock mode before adjusting the settings (see “Activating/deactivating the lock mode – Loc” on page 18).

Adjustment tips for the operating menu Adjusting the headphone volume – PHonE If you operate the receiver with a modified version of the GA 3041-C slot-in housing (see page 23), you can adjust the headphone volume via the “PHonE” menu. The volume can be adjusted between 0 and 126. Caution! High volume! Even short exposure to high volume levels can damage your hearing! Adjust the volume for the connected headphones to a medium level before putting the headphones on.
Selecting the frequencies to be stored in the channel bank “U” (variable bank) – tunE Via the “tunE” menu, you can freely select the frequencies to be stored in the channel bank “U” (variable bank). Via the “CHAn” menu, select the channel whose frequency you want to change. Note: The frequencies stored in the channel bank “F” (fixed bank) cannot be changed.
Selecting the standard display – dISP Via the “dISP” menu, you can select one of the following standard displays: Channel “CHAn” Frequency “FrEq” Battery status “BAt.tr” The selected standard display is shown y after switch-on, y after the parameters have been displayed for 15 seconds in display mode. Note: In order that the transmitter battery status can be displayed on the “BAt.tr” standard display, this functionality must be supported by the transmitter used (see “Suitable transmitters” on page 4).
Care and maintenance CAUTION! Water can damage the electronics of the receiver! Water entering the housing of the receiver can cause a short-circuit and damage the electronics. Only use a slightly damp cloth to clean the receiver. Do not use any solvents or cleansing agents.

Recommendations and tips ...for optimum reception To avoid overmodulating the receiver, maintain the recommended minimum distance of 5 m between transmitter and receiver. ...for multi-channel operation When operating a multi-channel system, make sure to only use intermodulation-free frequencies. For rapid calculation of intermodulation-free frequencies, you can use the SIFM (Sennheiser Intermodulation and Frequency Management) software, which can be downloaded from the Internet at www.sennheiser.
Additional information Diversity reception The EK 3241 operates on the “true diversity” principle: A receiving antenna receives not only the electromagnetic waves which reach it by a direct path, but also the reflections of these waves which are created in the room by walls, windows, ceilings and fittings. When these waves are superimposed, destructive interference occurs, which can also be called “field strength gaps”.
