ANALOGUE MODULATOR EQUIPMENT 912-MS Stereo modulators Description Analogue stereo modulator (ITU BS-707-4) in VSB vestigial side band, designed to work with adjacent channels. The audio input can be mono, stereo or dual by selecting the audio mode of the modulator by means of the programmer. Available in B/G standard.
Applications MATV installations where it is necessary to generate an analogue TV channel with stereo or dual sound from the audio and video signal from an equipment that has mono, stereo or dual sound.
Characteristics Essential features of this equipment are the high carrier to noise ratio together with a very reduced spurious level in the band. Modulation in VSB vestigial side band filtered by means of a SAW surface acoustic wave filter in any TV channel, including the interbands. F type connector and mini-DIN connector for audio/video. Supplied with the multiplexing bridge.
