5) Disconnect right and left channels on the encoder and verify that
the reading is now of about 7.5 KHz.
Monophonic Transmission
Before to execute this operation see as reference SETUP4.
1) Connect the signal source (audio mixer, receiver, compressor etc.)
to the MONO input (4 Fig.1A or 9 Fig.2B). This input is balanced
for USA version and unbalanced for EUROPA version.
2) Adjust INPUT LEVEL trimmer (3 Fig.1A or 8 Fig.2B) on the desired
level.
3) Adjust the signal level of the equipment connected to the
TEX20-N.V. (with the audio signal present) for a peak reading of
MAX DEV=75KHz.
Note that international standards permit a maximum deviation (DEV
MAX) of 75 KHz for frequency modulated, radiophones transmissions.
Exceeding this limit will only result in the degradation of signal
