8.1 Integrus Transmitter
The Monitoring sub-menu (2) on the transmitter is used to set which signal is sent to the
monitoring headphone output. It can be one of the inputs, one of the channels or no signal,
see also section 7.2.2 .
Use the monitoring headphone of the transmitter to check the input audio signal in the
transmitter, before it is sent to the receivers.
When the sensitivity of one of the inputs is being changed in the Setup menu (4I, 4J or 4K), or
when assigning inputs to channels (menu 4D, Per Channel), the monitoring output
automatically switches temporarily to that source, even when the option 'None' has been
chosen. When the headphone output is disabled (see section 7.2.12 ), the output level can
not be changed and the level indicator is not visible.
The 'Source/volume' screen also displays level meters (two for a stereo source, one for a
mono source) for a visual indication of the actual signal strength: = low level, = high level,
= overflow.
8.2 Integrus Receiver
The receivers can be switched to a test-mode to get an indication of the reception quality for
each carrier separately. To activate the test-mode: Push the channel selector to the Up-
position, press the on/off button and hold both for ca. 2 seconds. When in test-mode, switch
between carriers by using the channel selector.
For each carrier the display shows a relative value of the signal strength, Figure of
Merit(FOM), and a graphical quality indication symbol.
The reception quality can be assessed as follows:
