    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). To 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).
  • Page 11: Selecting The Mains Voltage / Mains Connection

    Selecting the mains voltage Before you plug the mains connector into the mains, please check first of all that the receiver is set to the correct mains voltage! You can change the mains voltage by removing the fuse holder turning it through 180° fuse holder.

  • Page 16: Setting A Receiving Frequency, Allocating A Frequency Memory And Assigning A Channel Number

    Setting a receiving frequency, allocating a frequency memory and assigning a channel number The EM 3532 receiver has a switchable frequency memory to store a maximum of 32 receiving frequencies with their respective channel numbers. The storing procedure is similar for each entry or modification: Press the buttons to select the “FREQUENCY”...
  • Page 17 With 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).

    Setting the receiving frequency via the channel number In the “CHANNEL” menu, you can directly change from one stored receiving frequency to the next. Press the buttons to select the “CHANNEL” menu. Then press the “CHANNEL” display on the display panel The display indicates the receiving frequency in alternation with the channel number.
  • Page 20: Squelch (Muting)

    Squelch (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”...
  • Page 21: Advanced Muting Function

    Advanced muting function This receiver also features AMF (Advanced Muting Function). 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.
  • Page 22: Automatic Transmitter Search Tuning - Scan Function

    Automatic transmitter search tuning – Scan function The 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.
  • Page 23 If no transmitter is found, the search tuning stops at the upper or lower limit of the 24 MHz frequency window. The display then indicates: If a transmitter with a strong enough RF signal (higher than the squelch level, but at least 5 μV) is found, this frequency is indicated on the display.
  • Page 24: Adding A Supply Voltage For Antenna Boosters

    Adding a supply voltage for antenna boosters Antenna 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.
