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-SEC2)
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-SEC2)
Channels 2-92, listed on the front and rear
41 dBmV output
3 year limited warranty

1. Power On Indicator: The LED indicates unit is powered on and operating.
2. Video Modulation: Used to set the video input level attenuation prior to modulation
3. Audio Modulation: Used to set the audio input level attenuation prior to modulation.
4. A/V Ratio: Adjusts the level of the audio RF carrier in proportion to the.
5. RF Output Level: Adjusts the RF output level to balance the modulated output at 41
dBmV.
WARNING: Adjusting the mini modulator RF output to operate higher than the rated 41 dBmV will
reduce the lifetime of the product and may damage the modulator. For a higher power output to
the system consider using active combiners or distribution amplifiers.
REAR PANEL
6. Video In: This “F” connector accepts composite video input from a satellite receiver, DVD
player or other equipment.
7. Audio In: The audio from the satellite receiver or DVD player is connected to these RCA
connectors. The audio inputs are combined into a mono-aural signal unless a stereo
encoder card is installed in the modu-lator.
8. RF Out: The modulated output signal comes out of this “F” connector to the combiner.
9. Power Plug: The three-pin power plug connects to a modulator power supply with 5 and
12VDC.

IMPORTANT
WARNING: This product is not WATERPROOFED. To reduce risk of electrical shock, fire hazard, or
damage to the unit, do not expose to rain or moisture.
CAUTION: To prevent electric shock, do not connect power supply until the power connections to
the modulation have been made.
NOTE TO INSTALLER: This reminder calls the system installer’s attention to Article 820-22 of the
NEC that pro-vides guidelines for proper grounding and, in particular, specifies that the cable
ground shall be connected to the grounding system of the building, as close to the point of cable
entry as practical.
HEADEND BALANCING
1. Let the headend warm up or “Burn-in” for at least 2 hours prior to calibrating.
2. Connect a calibrated RF signal meter or spectrum analyzer to the output of the highest
channel modulator.
3. Verify that the modulator is at 41 dBmV after the warm up time.
4. Connect modulator to the combiner.
5. Connect the RF signal meter or spectrum analyzer to the output of the headend. This
may be the combiner output or a distribution amplifier output.
6. Measure the highest channel to obtain the headend output level.
7. Keep the highest channel unchanged and attenuate the lower channels to match the
highest channel by reducing their RF Modulation output adjustment.
8. Fill headend balancing certificate with the headend output level, date, and signature.
9. Place the balancing certificate visible at the headend location.

Certificate of Calibration
I certify that this headend system at
has been burned, balanced, and tested in full working order in compliance with
the manufacturer balance specifications. This calibration is valid for a period of
twelve months.
