Product description
Programmable multiband ampliers with digital ltering are designed to amplify DTT signals in the VHF and UHF bands and
FM radio signals. These ampliers have up to 20 programmable high selectivity digital lters for DTT with a wide individual
AGC range and can be programmed to lter any VHF (170 ... 230 MHz), UHF (470 ... 694 MHz) channel.
The ampliers are also characterized by easy installation, a wide input level range, high selectivity, low power consumption,
high output level, output test point and LED indication (see Installation section). Each of the 20 lters allows to balance
adjacent channels due to high selectivity. Channels are automatically aligned according to the programmed UHF output
level and equalizer value. VHF channels will be adjusted according to the programmed UHF output level, the FM input has
a programmable gain control. DC power is provided through certain DTT inputs (switchable), see Specication.
The series consist of:
PA420T has 3 DTT inputs (2xVHF/UHF and 1xUHF) with 5G LTE ltering and 1 FM input. It has its own power supply.
PA321T has 2 DTT inputs (VHF/UHF) with 5G LTE ltering and 1 FM input. It has two powering modes:
- via DC IN (DC jack) from external 12 V DC power supply;
- via RF output from suitable receiver or 12 V DC power supply using power inserter.
The housing of ampliers meets more stringent screening requirements according to EN50083-2, class A.
The ampliers are intended for indoor use only.
Safety instructions
Installation of the ampliers must be done according to IEC60728-11 and national safety standards.
The amplier PA420T is powered from mains 230 V~. This voltage is dangerous to life.
The amplier PA420T is double isolated from the mains 230 V~.
The amplier PA321TP is powered from the external stabilized power supply +12 V DC. This voltage is not dangerous to life.
Any repairs must be done by skilled personnel.
Do not remove the cover of the power supply section, without disconnecting the unit from the mains supply.
Do not plug the amplier into the mains supply if the power cord or plug is damaged.
Do not plug the amplier into the mains supply until all cables have been connected correctly.
The mains socket must be easily accessible.
The amplier shall not be exposed to dripping or splashing water.
Avoid placing amplier next to central heating components, near highly combustible materials and in areas of high humidity.
If the amplier has been kept in cold conditions for a long time, keep it in a warm room no less than 2 hours before plugging
it into the mains.
Do not insert any objects into ventilation openings.
The ventilation should not be impeded by covering the amplier with items, such as newspapers, table-cloths, curtains.
Mount the amplier on not ammable wall or in not ammable installation box in vertical position with power supply unit on
the right side. Mount in locations where children not likely to be present.
From top, front and bottom of installed amplier must be at least 10 cm free space.
MONTAGE VIEW
Mount the amplier on the vertical position with power supply unit on the right side. The amplier must be xed with steel
screws Ø 4-5 mm. The screws are not included in a package.
IMPORTANT WARNINGS!
Before connecting any products to a system, it is essential to make sure the system power supply is switched o󰀨. Avoid
short-circuit or overload of any power supply. Never “HOT-SWAP” any system components as this may result in damage to
the newly introduced or existing components.

Installation and conguration instructions
Read the safety instruction rst.
Fit amplier on mounting place and connect all necessary RF cables, connect 75 Ω loads to the unused F sockets,
power on amplier. Adjust (green) and Error (red) LED’s blinking simultaneously briey. Adjust LED light up after that.
All congurations will be made with TERRnet App (see TERRnet App).
Connect Windows PC or Android smartphone to the amplier.
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 di󰀨erent 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.
