1.) INTRODUCTION
The Olson Technology LCM-550X12 can consist of twelve frequency agile F.C.C. compatible television
modulators in a single 3 ½” rack – mount chassis. The LCM-550X12 has a separate RF output for
each channel, and each channel may be operated at +45dBmV typical, +40dBmV guaranteed mini-
mum. The LCM-550X12 modulator is compatible with baseband scrambling techniques. No I.F.
loops are provided on these modulators.
Each of the twelve modulators will operate on any standard or cable channel from 55.25MHz to
547.25MHz (VHF channels 2 through 13 and cable channels 14 through 78). All channels are select-
able by front panel DIP switches and a front panel adjustment allows setting to F.C.C. offset
frequencies. HRC frequencies are available.
Each of the modulators in the LCM-550X12 offers the unique Olson Technology feature of >80dB
out-of-band carrier to noise ratio. These units use SAW filtering for adjacent channel operation, and
provide 60dB of spurious free dynamic range. These features allow virtually unlimited numbers of
LCM-550X12’s to be combined without the need for external bandpass filters.
The LCM-550X12 has low power consumption (approximately 5 watts per channel @ 115 VAC) for
economical and reliable long term operation.
