Automatic Channel Programming
To speed up the programming process, you can use the AUTO-TUNING function. When this
function is activated, the DSP40pro+ amplifier will automatically scan the inputs (1; 2; 3; 4) and
store only DVB-T/T2 signals with a level equal to or higher than the THRES threshold (factory
setting 55dBµV).

To start the AUTO-TUNING procedure select AUTO and
press ⏎. For best results, you will be asked to confirm some
parameters before starting the scan.
>LTE:5G
THRES:055dB
Select START to start automatic channels scanning. The
duration of the AUTO-TUNING procedure depends on the
number of channels received from the connected antennas.

Once the AUTO-TUNING procedure is complete, the display
will show the total output level calculated according to the
number of channels found in the scan. To confirm and complete
the procedure press the ⏎ key. If you wish to change the value
of the output level, use the ∇ ∆ keys and confirm by pressing
the ⏎ key.
Note:
An output level higher than that obtained
automatically can lead to a degradation
of signal quality.
