TDH digital/analogue TV converters TV channel converter modules in the TDH range is converting any TV channel in the VHF and UHF band to another frequency. For optimized function and performance in handling analogue or digital signals, two different versions are available. • Wide-range automatic gain control (AGC) secures right level into the distribution net • High modulation error rate (MER) valued by means of SAW filter technology, secures best possible signal quality • Full-range conversion • DC supply for preamplifier
