Installation and configuration instructions
Read the safety instruction first.
Fit amplifier on mounting place and connect all necessary RF cables, connect 75 Ω loads to the unused F sockets,
power on amplifier. Adjust (
green
) and Error (
red
) LED’s blinking simultaneously briefly. Adjust LED light up after that.
All configurations will be made with TERRnet App (see TERRnet App).
Connect Windows PC or Android smartphone to the amplifier
.
Select the necessary country (channels chart).
Select the necessary channels, output level, equalizer, FM gain and send it to the device.
Input channels numbers can’t be the same in different inputs.
Don’t select empty channels.
Reduce output level if use more than 6 MUX (see Technical characteristics).
Keep FM max output level 10 dB less than DTT signals.
During the parameters sending Adjust LED blinking (
green
). Error LED blinking (
red
) if the input level is too low or too
high for at least one selected channel.
