SMATV Catalogue
Multistandard double sideband indoor audio/video modulators. Output channel
programmable via dip-switch. Stable frequency output due to PLL Synthesis and
controlled via microprocessor. The modulator can be powered from the receiver
or using an external power supply (9-24V/80mA max). Packaging 1 pc.
This unit can be used to distribute signals from a receiver without a modulator
Audio/video input connection via SCART socket and high output level (90dBµV)
Adjustable audio/video inputs
