SMATV Catalogue
Fully agile audio video output modulators with double conversion, double saw filter
and tracking filter built in. A very high C/N ratio in the band enables the distribution
of more than 80 channels. Available in PAL B/G mono (SIG7282), PAL B/G stereo
(SIG7282S) and multistandard (SIG7281).
• Using only one modulator, the whole 47-862MHz band can be covered,
simplifying the installation and maintenance of the system
• High output level, 95dBµV, to mix all the channels together
• RCA (cinch) connectors for audio and video input and F connectors for RF output
• 70cm RCA cable and KPR41 solid bridge are included
• Programmable via FHM software
