input individually.
The + symbol means that power has been activated for a given input, while the - symbol that the input is disabled.

DVB-T VHF/UHF channel configuration.
To select the channels to amplify:
1.
Enter by pressing the right or left arrow until the display reads V-UHF 1..4. Values 1 – 4 correspond to the RF inputs
marked VHF/UHF 1 – 4. Select the appropriate menu for the input from which the channels are to be programmed and
click ENTER.
2.
The “ADDING CHANNEL” message will appear. Press ENTER.
3.
Now use the right/left arrow keys to select the channel number on which the DVB-T signal is to be received. Once
selected, press ENTER
4.
Next, select the channel number on which the signal is to be distributed in our network. The amplifier can freely convert
channel frequencies from VHF and UHF bands. A channel from UHF can be distributed in the UHF band only, similarly
a VHF channel in the VHF band only. After selecting the output channel, press ENTER.
5.
Now you observe the value of the input level measured in dBµV and select the output level needed for signal
distribution. Output level range — 96..116 dBµV. Confirm by pressing ENTER.
6.
The unit has an automatic limiter that will lower the maximum output level as the number of programmed channels
increases. For example, for 6 mux the maximum value is 112 dBµV.
7.
To add another channel from the same antenna, press the right arrow and program using the same method.
8.
After completing the adjustment process, press BACK.
9.
To delete a programmed channel, select it by entering the menu of the corresponding VHF/UHF input. Then hold down
the ENTER button until the “Channel deleted” message appears on the screen. Then press the BACK button to return
to the previous menu.
5.
FM and AUX adjustment.
The FM and AUX signal paths are not digitally processed. These are band amplified. To avoid overdriving the amplified signal:
1. Enable or disable the preamplifier option in the FM or AUX menu.
2. Take advantage of the built-in attenuator, which will properly attenuate excessively high signal levels.
The value of gain and maximum output level is available in the technical parameters table.
6.
Adjusts the output level and equalization.
In addition to individual output level settings for each amplified channel, a global output level can be set. With this option, all
signals will be transmitted with equal strength. In addition, the device has been equipped with a signal equalization function,
allowing to determine the appropriate difference between the signals from the beginning and the end of the band. Such sloped
signals can be distributed over sections with higher attenuation.
Output signal adjustment:
1. Press the right/left arrow to select EXIT. Press ENTER.
2. The option “Level: xxx dBµV" will be displayed. Press ENTER and use the right/left arrows to select the desired
value. Press ENTER to confirm.
3. Press the right/left arrow to enter “Slope: xdB”.
4. Press ENTER and use the arrows to select a value in the range -9 – 0dB.
a. 0 dB means equal gain for all channels
