EM 3532-U
The EM 3532-U consists of two complete true diversity receivers in a 19 housing.
The EM 3532-U has been specially designed for demanding theatre and broadcast
applications; it is fully suitable for multi-channel applications and can be used
with any UHF transmitter of the 3000, and 5000 series.
Each receiver of the EM 3532-U has 32 frequency memories to store up to 32 fre -
quencies with their respective channel numbers. The frequencies are tunable in 5 kHz
steps within a switching bandwidth of 24 MHz max. (i.e., each receiver has 4,800
freely selectable frequencies), so that, if a frequency has interference or is over-
loaded, you can simply switch to a different frequency.
The EM 3532-U is very flexible and reliable due to its menu-assisted operation. It is
also extremely easy to use: via the operating menu you can select and store receiv-
ing frequencies, select channel numbers and assign them to the receiving frequen-
cies, adjust the RF squelch, activate and deactivate the scan function (transmitter
search tuning), and switch on and off the booster supply voltage.
The multi-functional LC display shows either the selected receiving frequency or the
allocated channel number. On the display, two bargraphs represent the received RF
signal (“RF ) and the deviation of the AF signal (“DEV ). Furthermore – and pro-
vided that a Sennheiser transmitter transmitting a battery status signal is used – the
transmitter battery/accupack status is indicated in %. A flashing “LOW BATT dis-
play indicates that there are about 20 to 30 minutes of operation left. In addition,
the display shows the currently selected menu and all possible settings.
The EM 3532-U features a scan function (transmitter search tuning) for scanning
the frequency range for field strength levels. If a transmitter with a sufficient
field strength (at least 5 µV) is found, this frequency is automatically shown on
the display and can then be stored. For complex multi-channel applications, we
recommend controlling the receivers via a PC using the matching S-MCD software.

You can use the S-MCD to manage and control up to 126 EM 3532- and EM 1046
receivers. The EM 3532 receivers are coupled in series by means of data cables and
are subsequently connected to the PC via an RS 485 interface — additional inter-
face modules are not required. The EM 1046 receivers are connected to the parallel
interface of the PC via the EM 1046 DI display interface. For detailed information
of the installation of the EM 1046 receivers, please refer to the chapter ”5000
Series Receiver Systems“.
sing S-MCD you can program entire sequences of scenes with several actors
without having to change the transmitter/receiver unit. Each actor keeps his or
her transmitter and can be switched in when necessary. During operation you can
monitor battery status, volume level, and transmission frequency. If necessary,
you can switch to another frequency.
The “Receiver Configuration” window (see fig. 3) offers about the same displays
and menus that are also directly available on the receiver. The “RF” and “Dev”
bargraphs provide information on RF and AF levels. The “Batt” bargraph indicates
the battery status. With the “Squelch” control, you can determine the operating
thresh old for the RF squelch. The frequency list shows the frequencies and their
allocated channel numbers.
By clicking the “Scan up” and “Scan down” buttons, the EM 3532‘s scan function is
activated. If a frequency is found, it is displayed in the frequency list.
The RF recorder menu offers two operating modes. In the “RF Level Recorder”
mode you can record measuring values over a certain period of time. In the
“RF Spectrum Analyzer” mode (EM 3532 only) (see fig. 4) you can record measu-
ring data of a defined frequency range.
