The EM 3532-U receiver together with the suitable hand-held and pockettransmitters permits wireless transmission with studio-quality sound. Due to further optimised PLL and microprocessortechnology and the Sennheiser patented HiDyn plus? noise reduction system, these transmission systems surpass thesignal-to-noise ratio and dynamic range of modern CD productions. The true diversity technology of the EM 3532-U receiverensures interference-free transmission and minimises dropouts in the RF ally for small television studios and theatres, the simultaneous use of several Sennheiser 3000 series receivers –such as the EM 3532-U – is an economical alternative to technically more sophisticated and therefore more expensive multi-channel systems of the 5000 l featuresPLL microprocessor control, programmableSennheiser HiDyn plus noise reduction systemHigh transmission reliability due to true diversity receptionEase of use due to menu-assisted operationIndication of transmitter battery status and “LOW BATT” warning(only with Sennheiser transmitters transmitting battery status information)Rugged 19” 1 U metal housingDisconnectable supply voltage for external antenna boostersRemote-controllable via PC with S-MCD softwareExternal DC supply 11–18 V oltAdvanced scan function / transmitter search tuning40

3Noise reduction with HiDyn plus?Progress you can hear:This receiver is equipped with HiDyn plus?, the Sennheiser noise reduction system that reduces RF interference. Itincreases the signal-to-noise ratio in wireless audio transmission to up to 110 dB. The 96 dB dynamic range of a CD is thusconsiderably plus? is a wideband compander system which compresses the AF level on the transmitter side in a ratio of 2:1 (relatedto dB), and expands it in exactly the same way on the receiver side. The optimisation of the dynamic range and thesupporting effect of the control amplifier in the transmitter effectively reduce modulation plus? has been specially developed for use in high quality radiomicrophone ly transmitters which are also equipped with HiDyn plus? can work correctly incombination with the EM 3532-U receiver. If this is not the case, the dynamicrange is drastically reduced and the transmission sounds blunt and flat. HiDyn plus?cannot be switched off on the EM 3532 receiver.424Diversity receptionThe EM 3532 receiver 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 ofthese 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”. Repositioning the receiving antenna can bringa solution, provided the transmitter remains in its original position. With mobile transmitters, however (which allradiomicrophones are ), the “field strength gap“ will then occur with a different transmitter position. These “field strength gaps“can only be eliminated with true diversity receivers.

In true diversity, instead of one antenna and one receiver there are now two antenn? and two receiver sections. The antenn?are spatially separated. By means of a comparison circuit, the receiver section with the strongest RF signal is alwaysswitched to the common AF output. The risk of the occurrence of “field strength gaps” in both antenn? at the same time isvirtually display panel of the receiver always shows whether the diversity channel switched is channel A or channel B.43445Assembly and mountingUse as a stand-alone receiverWhen using the EM 3532 as a stand-alone receiver, it is easiest to use the supplied telescopic antenn?. They can bemounted quickly and easily to the rear of the receiver and are suitable for all applications where – good reception conditionsprovided – a wireless transmission system is to be used without a large amount of installation work. The best receptionquality, however, is obtained by using remote antenn? (see chapter 6).T o ensure that the receiver is securely mountedon a surface on which it cannot slip, four self-adhesive soft rubber feet are supplied. These feetare stuck into the recesses on the lower side ofthe that the recesses are clean and free from

grease before mounting the not use these feet if rack-mountingthe ng the receiver into a rackWith the two supplied rack mount “ears”, the receiver can be mounted into a 19” rack (1 U). The rack mount “ears” arescrewed to the receiver on the left and right ?.NoteIf you wish to connect the antenn? to the front side, you must pull the cables of theGA 3030-AM antenna mount through the holes on the rack mount “ears” beforemouting the “ears” ?.The GA 3030-AM antenna mount (accessory, see chapter 28) allows the antenn? to be connected to the front of the receiver,for example if the rear of the rack is the antenna holders to the right and left to the handles of the receiver ?. The connection cables, which are firmly fixedto the antenna holders, are connected to the antenna sockets on the rear of the ly instructionsDo not place the receiver in direct proximity to digitally controlled devices!Site the receiver as high as possible so that the receiving antenn have a“free line of sight” to the transmitter antenn?!45

466Connection and mounting of remote antenn?If the receiver position is not the best antenna position for optimum reception, you can use remote antenn? and antennaboosters. These are available as best reception quality is obtained with the Sennheiser A12 AD-UHF active antenna. Antenna and receiver can beconnected with RG 58 co-axial cable. Ready made up antenna cables from Sennheiser are available as accessories withlengths of 1 m, 5 m and 10 m (see chapter 28).?T o supply the antenna booster integrated in the A12 AD-UHF active antenna, a supply voltage needs to be added via theantenna sockets (see chapter 18).?External AB 1036-TV antenna boosters can be used for compensating for cablelosses if the remote antenn? are at a long distance from the receiver. The antenna boosters are connected in the antennacable line and can be supplied with the DC supply voltage by the EM 3532 via the antenna ial notes on mounting the antenn?Position antenn? in the same room in which the transmission takes place!?Maintain a minimum distance of 1 metre from metal objects (including reinforced concrete walls)!?Maintain a minimumdistance of 1 metre between receiving antenn?!7Selecting the mains voltageBefore you plug the mains connector into the mains, please check first of allthat the receiver is set to the correct mains voltage!Y ou can change the mains voltage by removing the fuse holder ? with the inserted fuse ?, turning it through 180°? andinserting it again ?. The set voltage can be seen at the top of the fuse connectionInsert the supplied mains cable into socket ? on the receiver and pass the cable through the cable grip ?.Because of the cable grip, the cable cannot slip out of socket ? and interrupt cable grip is particularly important when the receiver is permanently rackmounted. Inside the rack there are often a large number of cables - a cable gripprevents the cables from pulling each other out.47

8Putting the EM 3532 into operationThe receivers are switched on separately with the ON / OFF switches 2. The respective display panel ? is now lit up to showthat the receiver is switched on, and the standard display is shown (see chapter 11). The display “MUTE” ? (see chapter 15)lights up, and the RF field strength is indicated. If a suitable transmitter is already operating on this frequency, the display“MUTE” is initially lit up for about two seconds. Then the deviation is indicated ? (modulation, see chapter 21), and thediversity branch in use is now displayed for the first time (see chapter 4).After approx. ten more seconds, the battery status display indicates the (remaining) capacity of the transmitter’s battery orrechargeable accupack, provided the transmitter in use transmits a battery status signal (see chapter 24).NoteThe ON / OFF switch 2 works in the secondary circuit of the integrated mainstransformer, and thus only switches the low voltage side. By using a modern magneticcore transformer, the power consumption of a receiver of approx. 1/2 Watt whenswitched off is extremely low. For larger installations with several receivers, acomplete mains disconnection can best be achieved by an additional commonON / OFF AF connection is via sockets ? on the rear. The controls 1 control the AF signal output level.489Basic functions of the Sennheiser operating menu

A special feature of the Sennheiser 3000 series is the similar operation of transmitters and receivers. In stressfull situations,for example on stage or during a live show or presentation, it is important that the receiver is easy to operate and thatadjustments to the receiver settings can be made quickly and “without looking”. Therefore, the necessary operating steps foreach device must be the/buttons to select a menu:By briefly pressing the ?/? buttons, you can jump either forwards or backwards to the next menu. Y our selection is indicatedby the corresponding LC dot on the right of the display panel ?.Press the SET button to get into the setting mode:If you now press the SET button, the corresponding display on the display panel begins to flash, indicating that you are in thesetting mode of the selected the/buttons to adjust the settings of the selected the SET button to store the setting:T o store a setting, press the SET button until “Sto” briefly appears on the display, indicating that your setting has beenstored. The display then switches back to the standard ant: Only now is your setting stored!If you do not press the / buttons or the SET button for more than 30 seconds, the setting mode is automatically left and thedisplay switches back to the standard display.Y ou can discontinue your preselection by briefly (!) pressing the SET button.

5212Setting a receiving frequency, allocating a frequency memory andassigning a channel numberThe EM 3532 receiver has a switchable frequency memory to store a maximum of 32 receiving frequencies with theirrespective channel numbers. The storing procedure is similar for each entry or modification:Press the / buttons to select the “FREQUENCY ” menu. Then press the SET button. The“FREQUENCY MHZ ” display on the display panel ? begins to flash:With the / buttons you can now select a different display jumps to the next frequency in 5-kHz steps:When you get to the desired frequency, press the SET button until “Sto ” briefly appears onthe display.Y ou now have to check whether the frequency memory (nos. 1 to 32) is allocated display indicates the receiving channel with the allocated frequency memory, and the “CHANNEL ” display lights display for the frequency memory begins to flash.53With the / buttons you can now select a frequency memory (nos. 1 to 32). If the

frequency memory has been assigned a channel number, this is also indicated. If no channel number has been assigned,three “hyphens” appear on the display, indicating that the frequency memory is empty (see chapter 13).Have you set the frequency memory correctly Press the SET button until “Sto ” brieflyappears on the display.Y ou now have to assign the frequency memory a channel number (from 001 to 255). Withlarger systems, it is recommended to use the same channel numbers for both transmitters and receivers in order to providefor simpler monitoring of the system. With the ?/?buttons you can now select the desired channel number:Have you set the channel number correctly Press the SET button until “Sto ” briefly appearson the display. The display then switches back to the standard now does the receiver change to the new frequency / some countries, this menu is locked via a special configuration program, since not all tunable receiving frequencies areapproved in these countries. If the “FREQUENCY ” menu is selected, “Loc ”appears on the display.5413Deleting a receiving frequency, emptying a frequency memory ?Y ou can empty a frequency memory if you enter three“hyphens” when assigning a last frequency stored cannot be deleted. If you try to delete the last frequency stored,the display briefly indicates “LASt ” and then switches back to the standard display.Y ou can discontinue the programming ofthis menu by briefly (!) pressing the SET button. The display briefly indicates “ESC ” and then switches back to the standarddisplay. The previous settings are you do not press any of the three programming buttons for more than 30 seconds, the setting mode is automatically left. Thedisplay briefly indicates “ESC ” and then switches back to the standard display. The previous settings are some countries, this menu is locked via a special configuration program, since not all tunable receiving frequencies areapproved in these countries. If the “FREQUENCY ” menu is selected, “Loc ”appears on the display.

5514Setting the receiving frequency via the channel numberIn the “CHANNEL ” menu, you can directly change from one stored receiving frequency to the next.?Press the ?/? buttons toselect the “CHANNEL ” menu. Then press the SET button. The“CHANNEL ” display on the display panel ? begins to flash:The display indicates the receiving frequency in alternation with the channel number.?With the ?/? buttons you can nowselect a different channel. The display jumps eitherforwards or backwards to the next channel.
