7.3 Integrus Radiators
7.3.1 Setting the output power selection switch
The radiators can be switched to half power. This can be used when full power is not
required, e.g. when a mobile system is used in a small conference venue.
Also switch a radiator to half power when an adequate air flow can not be guaranteed, e.g.
when the radiator is mounted on top of an interpreters booth.
Reducing the power when possible saves energy and increases the lifetime.
7.3.2 Setting the delay switches
7.4 Determining the radiator delay switch positions
As described in section 4.2.6 , differences in the delays of the signals picked up by the
receiver from two or more radiators can cause black spots as a result of the multi path effect.
The signals picked up by the receiver are delayed by:
– the transmission from transmitter to radiator through the cable (cable signal delay)
– the transmission from radiator to receiver through the air (radiation signal delay)
– for systems with two or more transmitters: the transmission through the slave
transmitter(s)
To compensate the signal delay differences, the delay of each radiator can be increased.
These signal delays can be set with the delay switches at the back of the radiator.
The cable signal delays can be determined in the following two ways:
– by measuring the cable lengths
– by measuring the impulse response time with a delay measurement tool
In both cases the cable signal delays can be calculated manually and with the delay switch
calculation tool (available on the documentation CD-ROM).
It is not necessary to calculate the cable signal delay in case:
– the radiators are directly connected to the transmitter with equal cable length;
– radiators are loop-through connected, but with less than 5 m distance between the first
and last radiator in a trunk, and with equal cable length between the first radiator in each
trunk and the transmitter.
In these cases set the delay switches on all radiators to zero and determine whether to
compensate for radiation signal delay (see section 7.4.3 ).
The next sections describe how to calculate the delay switch positions manually for systems
with one transmitter, or two or more transmitters. See the delay switch calculation tool for
the procedures how to calculate the delay switch positions automatically.
Menu Item Options Description
4P Defaults ... Push the button to go to the sub-menu.
4P Defaults ... Reset to defaults?
* - No Cancel Reset.
- Yes Reset all options to the factory default value.
The user defined transmitters name, the user
defined language names and the transmission
mode are not reset.
CAUTION!
Turn the delay switches carefully to a new position until you feel that it clicks into position, to
prevent that a switch is positioned between two numbers, which would result in a wrong
delay setting.
