This MTCM-45 is a professional quality channelized heterodyne audio/video modulator with adjacent channel capability. The channel can be easily re-adjusted into the other channel in its group. Lo band, Mid band, Hi-band, Super band, Hyper band and Ultra band by changing the setting of oscillator dip switch and the returning of output filter. The PLL oscillator with microprocessor can control the output frequency to meet F.C.C required accuracy and off-setting. This modulator accepts standard polarity (sync negative) video in the range of 0.7V to 2.6V p-p.

  • Saw filter for superior vestigial side band response.
  • Microprocessor controlled frequency setting meets all F.C.C. accuracy and offsetting requirements.
  • Channel can be re-set within its band by re-setting dip switch and output filter only.
  • Pre-emphasis defeat switch accessible from side panel for the insertion of composite BTSC stereo signal.
