If more than 2 TV channels (included those fedinto the extension input) are used, see Reduction Table in technical annex.HPA. 47-862 Mz RF Power amplifier• Amplification of the combined multichannel signal in a ClassAassembly.• Variable attenuation is shared on two interstage sections, featuringdelayed behaviour on the first one. Maintenance of a low noisefigure.• Extension input allows coupling of the wideband signal provided byanother existing headend.• Each module is packed with a DC plug bridge, 53 mm length, forconnection of +12 VD voltage.74CATALOGUE 2013 · IKUSI
