Avoiding sources of interference Featuring automatic interference management, the devices are capable of
avoiding interfering signals at any time by automatically moving together to
unused frequencies in the 2.4 GHz frequency band, without any audio inter-
ruption. However, the number of usable radio links is reduced if there are
active sources of interference in the vicinity of the devices.
Switch off possible sources of interference operating in the 2.4 GHz fre-
quency band.
Possible sources of interference use e.g. WiFi or Bluetooth.
Infrared remote controls and headphones, DECT headphones and UHF radio
links (e.g. Sennheiser evolution wireless G3) do not represent a source of
interference and can remain switched on.
If you want to use WiFi while operating devices of the
series, use a dual-band WiFi router and deactivate its 2.4 GHz frequency
band in order to minimize interference to the radio links.
If conditions are optimal, you can operate up to 15 radio links simultaneously
(for details, see “Using the devices in multi-channel operation” on page 29).
Direct line of sight recommended Walls and other obstacles will reduce the range. Therefore, there should
always be a direct line of sight between the transmitting antenna and the
receiving antennas of a radio link. To ensure this, you can mount the antennas
of the receiver in different ways.
When using the EM D1 as a stand-alone receiver, you can mount the sup-
plied 2G4 rod antennas to the rear of the receiver (see page 16).
When rack-mounting the receiver, you should use the GA 4 rack-mount kit
to mount the receiver antennas to the front of the rack (see page 19).
You can identify and locate sources of interference using a WiFi scan-
ning tool.
