PMM* – Mini Modulator Instruction and Operation Manual
PMM* – Mini Modulator Technical Data
DESCRIPTION:
Professional quality channelized heterodyne audio/video modulator with SAW filter for adjacent
channel capability. The PLL oscillator with micro-processor can control the output frequency to
meet FCC required accuracy and off setting.
FEATURES:
Die cast housing
SAW Filtered for superior vestigial side band shaping and harmonic
reduction
Microprocessor controlled frequency setting meet all FCC accuracy and
off setting requirement
Upgrade to stereo with an optional stereo encoder card (PMM-SEC)
Channel can be reset within its band resetting dip switch and output
filter only
Factory upgradable for composite stereo with additional Stereo
Encoder Card (PMM-SEC)
Channels -9, listed on the front and rear
41 dBmV output
3 year limited warranty
