The programmable multiband channel amplifier PA321TP from TERRA has been designed for receiving digital terrestrial television (DVB-T/T2) in multi-family buildings, residences, hotels, boardinghouses, schools, hospitals, etc. The amplifier can be used as a signal amplifying element in MATV systems, multiswitch systems (SMATV), or systems based on distribution of signals from headends, modulators etc. High modulation error ratio MER of min. 36 dB allows to complete even the most complicated projects.
The amplifier is dedicated to difficult conditions of reception of RF signals, with signals of different levels, coming from one or several directions.
The amplifier has 2 programmable inputs for VHF band (174-240 MHz)/UHF band (470-694 MHz) and 1 input for FM band (87-108 MHz). The device has twenty independent amplification paths. Each path is used for amplifying one DVB-T/T2 digital terrestrial TV multiplex. This means that one device can amplify up to twenty digital multiplexes.
Each of the 20 amplifiers is equipped with automatic gain control (AGC) and ultra selective SAW (Surface Acoustic Wave) filter.
The automatic gain control ensures:
  • automatic signal level equalization for all channels regardless of the level at the input of the device (while maintaining the minimum required for proper signal quality) amounting to respectively 113 dBμV (for 6 MUXes). With this functionality, the installer does not have to worry about equalizing the level of all signals at the input of the system,
  • adaptation of gain level to periodical signal changes at the input of the system.
  • The device is programmed digitally using any Android mobile device or Windows PC (TERRnet app). The Control connector (microUSB jack) is used to connect the device to program the amplifier. When the amplifier is connected to the power supply, the green and red LEDs flash simultaneously to indicate that the amplifier is configured.
    The TERRA PA321TP amplifier can supply terrestrial TV antenna preamplifiers with DC 12V. The amplifier itself is powered with DC 12V from the included power adapter with current consumption of 0.45A (without external load), or remotely from the power supply (e.g. via coaxial cable).
