Troubleshooting
Channels are not adjusted to the programmed output level: Check that the
programmed fi lter for the highest output channel has both presence of signal
and the right level, since this value is taken as a reference for the adjustment of
the selected output level.
The channels entering through the input of BI/BIII (* BIII-VHF) are regulated
incorrectly: If we are entering only one channel through this input, its level
would be set 5dB below the UHF level channels. But if, with the same level, we
introduce several channels, the Avant will treat them like a higher-level single
channel, thus reducing the level adjusted of all of them regarding to the one it
would be obtained for just one channel.
If we need to amplify several channels coming from other processing units, we
recommend entering them on the input "Broadband (47-862 MHz)".
Channels in the broadband input are not equalised as regards fi lters:
The "broadband" input amplifi es signals coming from satellite receivers, the
recommended level for this input is between 70 and 74 dBμV (for UHF channels)
to get these channels equalised with the rest of the adjusted channels. If the
level applied is below the indicated range, these channels will have a lower level
than the rest; on the other hand, if the level is higher there will be disturbances
due to the intermodulation of channels.

The output level depends on the nº of channels.

begins with the verifi cation of the signal levels introduced in the FM (BI+FM)

input and fi nally with the verifi cation of the programmed fi lters. The
indication that the FM (BI+FM)
the signal in these inputs will not aff ect the rest of the selected channels.
We must remember that level indications in FM (BI+FM)
fi lters shown on the programmer's display, are a reference for the adjustment
process, being the unit able to balance channels, where a level error has been
found, whenever input levels do not present large variations as regards the
maximum specifi ed range.
