■ MENU DESCRIPTION

1. IN-VHF, IN-UHF1, IN-UHF2
This menu is repeated for each of the VHF / UHF inputs of the evo PRO 300.
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.
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).
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 from which channel is done the search. The
module will remove the whole channel list of that VHF / UHF 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 Add a new channel
On display figure:
 IN-UHF1 refers to the signal input port.
 Ch21 refers to the input channel.
 21 refers to the output channel.
 73 dBµV is the signal level automatically measured by the evo PRO 300.
After adding and saving a channel configuration, this is accessible through the channel list of that
input.
When adding a new output channel, it won't be allowed to choose a channel already used.
Maximum output channel count is 32, including all the processed channels of all the inputs.
:
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.
