The programmable, WWK ALPHA TELMOR multiband channel amplifier is dedicated for SMATV systems for the reception of DVB-T/T2 digital terrestrial television in multi-family buildings, residences, hotels, guesthouses, schools, hospitals, etc.
The amplifier is dedicated to difficult reception conditions with signals of various levels, transmitted from several directions. It has 4 programmable signal inputs for the VHF (174-240 MHz)/UHF (470-862 MHz) band, 1 for the FM band (88-108 MHz) and 1 AUX input (broadband), supporting 32 channels paths. The amplifier enables the reception, equalization and amplification of those signals. The automatic gain control system equalizes the signal level for all channels regardless of their level at the device input (while maintaining the minimum required for proper signal quality). The installer can freely configure the VHF/UHF inputs and optimize the individual channel levels at the installation site to ensure high-quality picture on the TV screen. The WWK ALPHA TELMOR channel amplifier can be used independently, as a part of a multiswitch system or part of a headend.
The WWK ALPHA TELMOR has a converter function that transforms any channel in the VHF/UHF band to another in the VHF/UHF band.
The device supplies 12 VDC voltage with a maximum of 50 mA to the antenna preamplifier.
LTE filter options ensure resistance to interference from LTE networks operating in 4G (>790 MHz) and 5G (>694 MHz) technology.
The amplifier can only be installed indoors.
