Recommendations and tips
... for optimum reception
• Transmission range depends to a large extent on location and can vary from about 10 m
to about 150 m. There should be a “free line of sight” between transmitting and receiving
antennas.
• If, with the EM 2000 receiver, reception conditions are unfavourable, you should use two
remote antennas which are connected via antenna cable.
• To avoid overloading the receiver, observe a minimum distance of 5 m between transmit-
ting and receiving antennas.
• Observe a minimum distance of 50 cm between receiving antennas and metal objects
(such as cross members or reinforced-concrete walls). Align the antennas upwards in a
V-shape.
... for multi-channel operation
• Each of the frequency banks “1” to “20” accommodates factory-preset receiving
frequencies which are intermodulation-free. For possible frequency combinations, please
refer to the supplied frequency information sheet.
• The channels in the frequency banks “U1” to “U6” can be assigned freely selectable
frequencies (see page 26).
• When using several transmitters simultaneously, interference can be avoided by main-
taining a minimum distance of 20 cm between two transmitters.
• Use accessories recommended by Sennheiser for multi-channel applications (see
page 37).
