■ MENU DESCRIPTION
1. RF-IN
This menu is repeated for each of the four VHF / UHF inputs of the evo PRO 100 .
1.1 Pre-Amplifier
Enable or disable the pre-amplifier action in each VHF / UHF input of the module.
The pre-amplifier option increases the signal power of that input before the filtering and conversion
blocks. An excessive level of the channels to process in this part reaching saturation, or an increase
of noise level, can degrade signal quality. Therefore, it is recommended to know about signal quality
on the input side (gain, tilt, bandwidth and noise figure) when applying pre-amplifier to measure its
impact on the output side.
1.2 Antenna Power
Each input connector is capable of supplying 12V, 100mA (max) to an active antenna or an external
pre-amplifier. This menu allows the user to turn on / off the power on each input port.
1.3 Auto Scan
Automatic channel search. First, it must be configured between which channels is done the search.
The module will remove the whole channel list of that RF input and will test each channel presence.
Channels with a minimal signal level (> 50 dBµV) will be added to that RF input channel list, with the
same channel at the output. In case the output channel would be used by another RF input, the
channel won’t be added to the list. Then, the user will be able to edit the detected channels, changing,
removing or adding new ones.
1.4 Channel list
Each VHF / UHF input will have its own list of managed channels.
Maximum output channel count is 32, including all the managed channels of all the inputs.
The channel list is made up of all the channels detected after doing the automatic scan for that
input and the channels added through that specific menu.
Up and down arrows on the keyboard can be used to move through the channel list.
For each channel of the list, the following information will be displayed on the LCD:

IN-UHF 1 refers to the port of the signal input.

Ch21 refers to the input channel.

21 refers to the output channel.

73 dBµV is the signal level automatically measured by the evo PRO 100 .
Recommendation
:
Turn on the Pre-Amplifier only when the input signal level of one of
the channels to process of that input, is too low (lower than 60 dBµV).
NOTE : In the same RF input there could be low level channels
along with other high level channels, wanting both to be
processed. The pre-amplifier action could disturbed the high
level channels degrading its signal quality.
All the channels of the RF input to be processed must be
considered to decide to turn on / off its pre-amplifier.
