After pressing the
the FM, VHF and programmable single-channel amplifiers to the programming unit.
At the start of the adjustment of each amplifier, a letter or a number appears consecutively on the displaywith
two dashes, that indicates the amplifier under adjustment:
If the adjustment is satisfactory (within the specified margins for the equipment), the programming unit will
automatically run through all of the active amplifiers and will end the adjustment indicating the menu option displayed
when the button was pressed.
If an adjustment error occurs, the amplifier affected will show up on the display as well as the type of error that
has been detected: whether due to a too high or too low level.
REMARK: When a level error occurs, the system does not go on with the adjustment, and instead remains on
stand-by, so that the user can decide between two possible options:
a).- Try to correct the input level of the amplifier with the error and then measure it again using the
If the level is now correct, the adjustment process is allowed to go on. If the opposite is the case, the
programming unit will again display an error and will allow us to repeat the process until the input level is
within the operating range of the equipment.
b).- Continue with the adjustment without correcting the level error. To do this, press the
How to use the "Reset" button
The "Avant" unit can be programmed before the installation process and without the need for an input signal,
thereby allowing the subsequent adjustment of the levels in the installation without the need to use the programmer, via
the "Reset" button, located to the left of the programmer's connector.
This is done with the following process:
We must select the adequate parameters for the installation using the programmer (the channels, the output
level, the equalisation slope...) and then press the adjustment button
without the input signal, the adjustment will stop if it does not detect an FM signal. It is now possible to take the remote
control away because though the adjustment process has been interrupted, the selected data has been memorised by
the unit.
Later, in the installation, and after connecting the inputs that are being used and loading the output with 75 , we
will only have to activate the "Reset" button for the unit to carry out the adjustment process. The adjustment of the
"Avant" unit, using the "Reset" button, is carried out in the same way as with the programmer, though in this case the
process will not stop even if the unit detects an error in the input levels and the red error LED will come on, only when
there is a level error in any of the single-channels.
If the unit has already been programmed with the desired parameters for the installation (channels, output levels,
sloped gain,...), when the "Reset" button is pressed, the "Avant" unit performs an automatic adjustment of the levels in
the same way as when the adjustment button
