Terra PA420T Quick Start Manual

Programmable multiband amplifiers PA420T, PA321TP
Product description
Programmable multiband amplifiers with digital filtering are designed to amplify DTT signals in the VHF and UHF bands and
FM radio signals. These amplifiers have up to 20 programmable high selectivity digital filters for DTT with a wide individual
AGC range and can be programmed to filter any VHF (170 ... 230 MHz), UHF (470 ... 694 MHz) channel.
The amplifiers 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 filters 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 Specification.
The series consist of:
PA420T has 3 DTT inputs (2xVHF/UHF and 1xUHF) with 5G LTE filtering and 1 FM input. It has its own power supply.
PA321T has 2 DTT inputs (VHF/UHF) with 5G LTE filtering 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 amplifiers meets more stringent screening requirements according to EN50083-2, class A.
The amplifiers are intended for indoor use only.
Safety instructions
Installation of the amplifiers must be done according to IEC60728-11 and national safety standards.
The amplifier PA420T is powered from mains 230 V~. This voltage is dangerous to life.
The amplifier PA420T is double isolated from the mains 230 V~.
The amplifier 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 amplifier into the mains supply if the power cord or plug is damaged.
Do not plug the amplifier into the mains supply until all cables have been connected correctly.
The mains socket must be easily accessible.
The amplifier shall not be exposed to dripping or splashing water.
Avoid placing amplifier next to central heating components, near highly combustible materials and in areas of high humidity.
If the amplifier 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 amplifier with items, such as newspapers, table-cloths, curtains.
Mount the amplifier on not flammable wall or in not flammable 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 amplifier must be at least 10 cm free space.
MONTAGE VIEW
Mount the amplifier on the vertical position with power supply unit on the right side. The amplifier must be fixed 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 off. 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.
