The EM 3532-U receiver together with the suitable hand-held and pocket transmitters permits wireless transmission with studio-quality sound. Due to further optimised PLL and microprocessor technology and the Sennheiser patented HiDyn plus™ noise reduction system, these transmission systems surpass the signal-to-noise ratio and dynamic range of modern CD productions. The true diversity technology of the EM 3532-U receiver ensures interference-free transmission and minimises dropouts in the RF link.Especially 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 series.Special featuresțPLL microprocessor control, programmablețSennheiser HiDyn plus™ noise reduction systemțHigh transmission reliability due to true diversity receptionțEase of use due to menu-assisted operationțIndication of transmitter battery status and “LOW BATT” warning(only with Sennheiser transmitters transmitting battery status information)țRugged 19” 1 U metal housingțDisconnectable supply voltage for external antenna boostersțRemote-controllable via PC with S-MCD softwarețExternal DC supply 11–18 V oltțAdvanced scan function / transmitter search tuning40412Connections and operating elements ᕡHeadphone socket 1/4 ” (6.3 mm) øᕢHeadphone volume control ᕣMulti-function LC display panel ᕤButtons for selecting and programming the menus ᕥSET/storage button ᕦON / OFF switch ᕧFuse holder and mains voltage selection ᕨ2-pin IEC mains connector ᕩCable grip for mains cable µData interface for connecting a remote computer ¸AF output XLR-3M, balanced ¹Control for the AF output level at the XLR socket ¸ƸAntenna input B ƹDC socket (e.g. for use in an OB van)ƺAntenna input A3Noise reduction with HiDyn plus™Progress you can hear:This receiver is equipped with HiDyn plus™, the Sennheiser noise reduction system that reduces RF interference. It increases the signal-to-noise ratio in wireless audio transmission to up to 110 dB. The 96 dB dynamic range of a CD is thus considerably surpassed.HiDyn plus™ is a wideband compander system which compresses the AF level on the transmitter side in a ratio of 2:1 (related to dB), and expands it in exactly the same way on the receiver side. The optimisation of the dynamic range and the supporting effect of the control amplifier in the transmitter effectively reduce modulation problems.HiDyn plus™ has been specially developed for use in high quality radiomicrophone systems.NoteOnly 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 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”. Repositioning the receiving antenna can bring a solution, provided the transmitter remains in its original position. With mobile transmitters, however (which all radiomicrophones 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 antennæ and two receiver sections. The antennæ are spatially separated. By means of a comparison circuit, the receiver section with the strongest RF signal is always switched to the common AF output. The risk of the occurrence of “field strength gaps” in both antennæ at the same time is virtually nonexistant.The 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 antennæ. They can be mounted quickly and easily to the rear of the receiver and are suitable for all applications where – good reception conditions provided – a wireless transmission system is to be used without a large amount of installation work. The best reception quality, however, is obtained by using remote antennæ (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 receiver.Ensure that the recesses are clean and free fromgrease before mounting the feet.NoteDo not use these feet if rack-mountingthe receiver.Mounting 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” are screwed to the receiver on the left and right ቢ.NoteIf you wish to connect the antennæ 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” ቤ.The GA 3030-AM antenna mount (accessory, see chapter 28) allows the antennæ to be connected to the front of the receiver, for example if the rear of the rack is closed.Mount the antenna holders to the right and left to the handles of the receiver ባ. The connection cables, which are firmly fixed to the antenna holders, are connected to the antenna sockets on the rear of the receiver.Assembly instructionsțDo not place the receiver in direct proximity to digitally controlled devices!țSite the receiver as high as possible so that the receiving antennæ have a“free line of sight” to the transmitter antennæ!45466Connection and mounting of remote antennæIf the receiver position is not the best antenna position for optimum reception, you can use remote antennæ and antenna boosters. These are available as accessories.The best reception quality is obtained with the Sennheiser A12 AD-UHF active antenna. Antenna and receiver can be connected with RG 58 co-axial cable. Ready made up antenna cables from Sennheiser are available as accessories with lengths of 1 m, 5 m and 10 m (see chapter 28).ǠT o supply the antenna booster integrated in the A12 AD-UHF active antenna, a supply voltage needs to be added via the antenna sockets (see chapter 18).ǠExternal AB 1036-TV antenna boosters can be used for compensating for cablelosses if the remote antennæ are at a long distance from the receiver. The antenna boosters are connected in the antenna cable line and can be supplied with the DC supply voltage by the EM 3532 via the antenna cables.Essential notes on mounting the antennæțPosition antennæ in the same room in which the transmission takes place!țMaintain a minimum distance of 1 metre from metal objects (including reinforced concrete walls)!țMaintain a minimum distance of 1 metre between receiving antennæ!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 ᕧ with the inserted fuse ቢ, turning it through 180°ባ and inserting it again ቤ. The set voltage can be seen at the top of the fuse holder.Mains connectionInsert the supplied mains cable into socket ᕨ on the receiver and pass the cable through the cable grip ᕩ.Because of the cable grip, the cable cannot slip out of socket ᕨ and interrupt operation.NoteA 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.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 show that the receiver is switched on, and the standard display is shown (see chapter 11). The display “MUTE” ቢ (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 ባ (modulation, see chapter 21), and the diversity 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 or rechargeable 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 switch.The AF connection is via sockets ¸ on the rear. The controls ¹ control the AF signal output level.9Basic functions of the Sennheiser operating menuA 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 that adjustments to the receiver settings can be made quickly and “without looking”. Therefore, the necessary operating steps for each device must be similar.ᕡPress thẽ/̅buttons to select a menu:By briefly pressing the ̃/̅ buttons, you can jump either forwards or backwards to the next menu.

The storing procedure is similar for each entry or modification:ǠPress the ̃/̅ buttons to select the “FREQUENCY” menu. Then press the SET button. The “FREQUENCY MHZ” display on the display panel ᕣ begins to flash:ǠWith the ̃/̅ buttons you can now select a different frequency.The display jumps to the next frequency in 5-kHz steps:ǠWhen you get to the desired frequency, press the SET button until “Sto” briefly appears on the display.ǠY ou now have to check whether the frequency memory(nos. 1 to 32) is allocated correctly.The display indicates the receiving channel with the allocated frequency memory, and the “CHANNEL” display lights up. The display for the frequency memory begins to flash.ǠWith 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).ǠHave you set the frequency memory correctly? Press the SET button until “Sto” briefly appears on the display.ǠY ou now have to assign the frequency memory a channel number (from 001 to 255). With larger systems, it is recommended to use the same channel numbers for both transmitters and receivers in order to provide for simpler monitoring of the system. With the ̃/̅buttons you can now select the desired channel number:ǠHave you set the channel number correctly? Press the SET button until “Sto” briefly appears on the display. The display then switches back to the standard display.Only now does the receiver change to the new frequency / channel.For some countries, this menu is locked via a special configuration program, since not all tunable receiving frequencies are approved in these countries. If the “FREQUENCY” menu is selected, “Loc”appears on the display.13Deleting a receiving frequency, emptying a frequency memoryǠY ou can empty a frequency memory if you enter three “hyphens” when assigning a channel number.ǠThe 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 of this menu by briefly (!) pressing the SET button. The display briefly indicates “ESC” and then switches back to the standard display. The previous settings are kept.If you do not press any of the three programming buttons for more than 30 seconds, the setting mode is automatically left. The display briefly indicates “ESC” and then switches back to the standard display. The previous settings are kept.For some countries, this menu is locked via a special configuration program, since not all tunable receiving frequencies are approved in these countries. If the “FREQUENCY” menu is selected, “Loc”appears on the display.14Setting the receiving frequency via the channel numberIn the “CHANNEL” menu, you can directly change from one stored receiving frequency to the next.ǠPress the ̃/̅ buttons to select the “CHANNEL” menu. Then press the SET button. The “CHANNEL” display on the display panel ᕣ begins to flash:The display indicates the receiving frequency in alternation with the channel number.ǠWith the ̃/̅ buttons you can now select a different channel. The display jumps either forwards or backwards to the next channel. The next channel is not necessarily identical with the next channel number assigned!The display indicates the new channel in alternation with the receiving frequency assigned.NoteIf you have reached the first or the last frequency memory, the display briefly indicates “EndtAb”. Continue with your selection in the opposite direction.ǠHave you selected the desired channel? Press the SET button until “Sto” briefly appears on the display. The display then switches back to the standard display.Only now does the receiver change to the new frequency / channel.15Squelch (Muting)The EM 3532 receiver is equipped with an adjustable squelch which eliminates annoying noise when the transmitters are switched on and off. It also suppresses sudden noise when a transmitter leaves the reception area and there is no longer sufficient transmitter power received by the receiver. The adjustment of the squelch is via the “SQUELCH” menu. The adjustment range is between 0 and 134 (on the display), which corresponds to 0 to up to 100 μV. When the squelch is active, the display “MUTE” is lit up on the display panel. If set to position “0”, the squelch is switched off.ǠPress the ̃/̅ buttons to select the “SQUELCH” menu. Then press the SET button. The LC dot on the left of the text SQUELCH begins to flash and the current value of the squelch is shown on the alphanumeric main display and in the deviation bargraph. For the exact value in μV please refer to the RF level bargraph on the left of the deviation bargraph:ǠWith the ̃/̅ buttons you can now select a squelch threshold between 0 and 134.ǠOnly after having been stored does the new squelch treshold become effective. T o store a setting, press the SET button until “Sto” briefly appears on the display, indicating that your setting has been stored. The display then switches back to the standard display.Y ou can discontinue the programming of this menu by briefly (!) pressing the SET button. The display briefly indicates “ESC” and then switches back to the standard display. The previous settings are kept.If you do not press any of the three programming buttons for more than 30 seconds, the setting mode is automatically left. The display briefly indicates “ESC” and then switches back to the standard display. The previous settings are kept.16Advanced muting functionThis receiver also features AMF (A dvanced M uting F unction). This special electronic feature comes into effect when an RF signal drops by about 40 dB in a short time. The reception is then muted for at least three seconds. AMF thus suppresses the annoying switch-off click when a transmitter is switched off. Because of the delay in switching on again, the PLL circuit of the transmitter has enough time to adjust itself back to the corresponding transmission frequency.ExampleOne possible area of use for AMF is the inaudible change of a hand-held transmitter.If the battery of the first transmitter has run down (display “LOW BATT” on thereceiver), a second transmitter is prepared on the same frequency: insert battery,select transmission channel. Then the first transmitter is switched off, AMF switchesto mute and the second transmitter is switched on. The PLL of transmitter 2 stabilisesitself, AMF switches on again. The whole procedure takes place inaudibly in thebackground while AMF is switched to mute. Without AMF, the switching off,switching on and stabilising of the transmission frequency would have been audiblein the form of possible crackles and whistling noises.AMF can be switched off. As it is coupled with the setting of the normal squelch, its function is cancelled if the squelch is set to position “0” (see chapter 15).17Automatic transmitter search tuning – Scan functionThe EM 3532 receiver features a scan function to scan the frequency range of the tuner for a transmitter.For some countries, this menu is locked via a special configuration program, since not all tunable receiving frequencies are approved in these countries. If the “SCAN” menu is selected, “Loc” appears on the display.ǠPress the ̃/̅ buttons to select the “SCAN” menu. “SCAn” appears on the display:Then press the SET button. The current receiving frequency set appears on the display, and the “FREQUENCY MHZ” display as well as the LC dot on the left of the text SCAN begin to flash.ǠWith the ̃/̅ buttons you can now start the transmitter search tuning either upwards or downwards. During transmitter search tuning, the display indicates:or:ǠIf no transmitter is found, the search tuning stops at the upper or lower limit of the24 MHz frequency window. The display then indicates:ǠIf a transmitter with a strong enough RF signal (higher than the squelch level, but at least5 μV) is found, this frequency is indicated on the display. In addition, the deviation and theRF level of the received signal are indicated via the bargraphs. Y ou can now monitor the sound signal with headphones.Information on how to store the new receiving frequency is given in chapter 12.NoteIf you wish to acquire data from your transmitters in use via this menu, themodulation of the transmitters must not be too high, otherwise frequency deviationsmay occur. The solution to this problem is simple: do not talk into the transmitterwhen the search tuning is activated. In general, it is best to put the transmitterdown!Y ou can discontinue the programming of this menu by briefly (!) pressing the SET button. The display briefly indicates “ESC” and then switches back to the standard display. The previous settings are kept.NoteIn this menu, the display does not switch back to the standard display after 30seconds. The search tuning between the two limits of the frequency window takesabout 12 – 15 seconds, and you should have time enough to write the new frequencydown or to compare it with a frequency table.ǠPress the SET button to leave this menu!18Adding a supply voltage for antenna boostersAntenna boosters can be connected to the antenna inputs of the EM 3532 receiver and can be supplied by the receiver via the antenna cables. The supply voltage can be switched on or off.Both receivers in the EM 3532 should be set to the same setting, i.e. both receiver should be set to either “On” or “OFF”!ǠPress the ̃/̅ buttons to select the “BOOSTER FEED” menu. The current setting – i.e. “On”or “OFF” – is indicated on the display.Then press the SET button. The “BOOSTER FEED” display on the display panel begins to flash.Y ou can now select your desired setting:ǠPress the ̅ button to switch on the booster supply voltage, “On” appears on the display:ǠPress the ̃ button to switch off the booster supply voltage, “OFF” appears on the display:ǠY our setting has to be stored before it becomes effective. T o store a setting, press the SET button until “Sto” briefly appears on the display, indicating that your setting has been stored. The display then switches back to the standard display.If the booster supply voltage is switched on, the “BOOSTER FEED” display on the display panel is lit up.Y ou can discontinue the programming of this menu at any time by briefly (!) pressing the SET button. The previous setting is then kept. If you do not press any of the three programming buttons for more than 30 seconds, the setting mode is automatically left and19Stand-by operationThe EM 3532 receiver can be set to stand-by operation. During stand-by operation, information from the RF section is no longer processed and the AF section is muted (MUTE). All other menus – except for “REMOTE” and “STANDBY” – are locked. If you try to select any other menu, “Loc”appears on the display.ǠPress the ̃/̅ buttons to select the “STANDBY” menu. The current setting – i.e. “On” or “OFF” – is indicated on the display.Then press the SET button. The “STANDBY” display on the display panel begins to flash.Y ou can now select your desired setting:ǠPress the ̅ button to switch on the stand-by operation, “On” appears on the display:ǠPress the ̃ button to switch off the stand-by operation, “OFF” appears on the display:ǠY our setting has to be stored before it becomes effective. T o store a setting, press the SET button until “Sto” briefly appears on the display, indicating that your setting has been stored. The display then switches back to the standard display.If the receiver is set to stand-by operation, the “STANDBY” display on the display panel is lit up.Y ou can discontinue the programming of this menu at any time by briefly (!) pressing the SET button. The previous setting is then kept. If you do not press any of the three programming buttons for more than 30 seconds, the setting mode is automatically left and20Remote controlThe EM 3532 receiver can be set for “computer remote control only”. When set for remote control, all other menus – except for “REMOTE” – are locked. If you try to select any other menu, “Loc”appears on the display.ǠPress the ̃/̅ buttons to select the “REMOTE” menu. The current setting – i.e. “On” or “OFF” – is indicated on the display.Then press the SET button. The “REMOTE” display on the display panel begins to flash.Y ou can now select your desired setting:ǠPress the ̅ button to switch on the remote control, “On” appears on the display:ǠPress the ̃ button to switch off the remote control, “OFF” appears on the display:ǠY our setting has to be stored before it becomes effective. T o store a setting, press the SET button until “Sto” briefly appears on the display, indicating that your setting has been stored. The display then switches back to the standard display.If the receiver is set to remote control, the “REMOTE” display on the display panel is lit up.Y ou can discontinue the programming of this menu at any time by briefly (!) pressing the SET button. The previous setting is then kept. If you do not press any of the three programming buttons for more than 30 seconds, the setting mode is automatically left and the previous setting is also kept.。
