I tuned into several analogue CATV channels and DVB C transponders Too little or too much amplification will both result in a not so good signal Also equalization with the TILT knob makes much difference Having the separate TEST connector is a blessing it provides the signal with 20dB attenuation This makes it possible to setup the signal while you are actually working at the Catline TVB 02 Hook up the meter and tune the amplification and TILT for perfect results A clever idea by Macab as otherwise you would have to constantly run back and forth between the Catline TVB 02 and the network socket 9 Satisfied with my quick test wanted to put the Catline TVB 02 to use in a bigger networking environment so set it up in one of the network racks in the office Again as long as you can provide the original TV signal in a coaxial cable setting up the Catline TVB 02 is a quick job Just plug in the network cables and off you go This time I just unplugged the cables from the switch and into the Catline TVB 02 The network socket provides now a TV signal instead of the network signal ANALOG TV CH 108 VID FREQ 154 25 MHz AUD FREQ 159 75 MHz INFORMATION PAL_DK 50Hz a ec CHARGER e POWER DRAIN 18 53 01 4 ae S ns J h Ta lt a a we am en ad i 0l 0 4 W c sudiov
