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 500 G3 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 transmitting 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 39).
• When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
• Use accessories recommended by Sennheiser for multi-channel appli-
cations (see page 53).
