Description
 
AH1916AM AGILE
16 IN 1HEADEND USER MANUAL


INTRODUCTION

The AH1916AM is a 4RU rack mounted chassis that allows for installation of up to 16 pieces high quality SAW filtered frequency agile modulators covering 860MHz. Built-in active combiner eliminates unnecessary cabling and potential connection problem and ensures high output level. Low out-of-band noise makes it ideal in adjacent channel headend.

FEATURES
  1. Full frequency agility allows the rapid creation of channel lineups
  2. Each channel is completely independent. Channel configuration is flexible
  3. Two cooling fans for heat-sinking prolong the service life
  4. None-volatile memory ensures channel programming remains after power loss
  5. Two-digit LED display provides quick channel identification
  6. Available in NTSC or PAL configurations

WARNING:

For the protection of your equipment and its proper working is necessary to connect the

AH1916AM to a ground connection. 
UNPACKING AND HANDLING
A full set AH1916AM is shipped with all equipment assembled, wired, factory tested, and then packed in
an appropriate shipping container. Ensure that all accessories are removed from the container and packing
material before they are discarded.
INSPECTION
Inspect the front and rear of the equipment for shipping damage. Make sure the equipment is clean, and no
wire, cables, or connectors are broken, damaged or loose.
DAMAGE IN SHIPMENT
Should any damage be discovered after unpacking the unit, immediately file a claim with the carrier.
A full report of the damage shall be made and a copy forwarded to vendor.
PRECAUTIONS
PRECAUTIONSREQUIREMENTS
Avoid heat buildupAllow rack space (1'')between powered headend product in the equipment
Ensure easy access to rack wiringAllow a minimum of 18inches behind the equipment rack
Facilitate servicing and maintenanceAllow a minimum of 36'' of clearance in front of the equipment rack
Avoid direct heating or air conditioningIf unavoidable, use deflector plates
AC power source outletsLocate equipment near sufficient outlets to provide power for test equipment and power tools
Rack supportMake certain rack supports are sufficiently rigid to support racks
Building leakageBeware of dripping water onto equipment from leaky roofs, waveguide roof entries, and cold water pipe condensations

QUICK INSTALLAION
The AH1916AM is designed for indoor 19'' rack. Make sure a space is left between modulators for air circulation. To prevent electric shock, never remove the ground pin. Insure that electrical input cables entering the building be connected to the building ground as close to the entry point as possible.
  1. Feed in the Audio and Video connectors before turn on the power
  2. Warm up the modulator and check the picture and audio
  3. Set up the channels you want if the factory settings are not what you want
ADJUSTMENT

All SOUKA modulators are heat cycled at the factory and final adjustment are made with the units hot. Thus, allow a 20 minutes warmup before attempting any adjustments. You will need a signal level meter and a TV set.
  1. Connect the video and audio cable from your source to the respective connector on the modulator. If you have several AH1916AM, please connect the RF OUTPUT to the proper combiner. Levels can be read at the test point output of combiner output in the rear panel.
  2. The AV ADJ. should always be between -15dB to -17dB below the VIDEO ADJ.. Once this ratio is set it will track with the VIDEO ADJ. (All are proper set at the factory.)
  3. AUDIO and VIDEO modulation levels are set at the factory for plus or minus 25KHz deviation and 87.5% depth of modulation respectively. Although proper test equipment should be used, minor adjustment can be made utilizing a TV set.
    3.1  Connect the TV set to the final output test point so that its signal level input from the modulator is   about +69dBµV. If the colors look bright and there is sufficient sound without audio buzz, leave the modulation adjustment alone. If there is occasional audio buzz, turn modulation control down slowly counter-clockwise until the audio is clean.
    3.2  If the modulator picture is dark, raise the V ADJ. control slowly until the picture just becomes over bright and begins to distort. Lower the control about 1/8 turn from this point.
    3.3  If the modulator audio is low, try and set TV audio level utilizing an off air signal. Subjectively match this level utilizing the A ADJ. control. Check that all audio levels are about the same when switching channels.

COMMON TROUBLESHOOTING

1. Herringbone in TV

Disconnect modulator from local channels and check modulated channel. If there is programming move the modulated channel. If the picture is snowy, use a low pass filter to block noise or data coming in from cable.
2. Horizontal Bars Rolling Through TV Picture

Check for a component of the system that is introducing DC power into the system. Disconnect that component and check TV. If the hum bars stop, use a DC blocker down stream from that component to block the power from getting to the TVs.
 If the rolling is only on the modulated channels, check for impedance mismatch by adjusting the video level adjustment pot.
3. Vertical Bars Rolling Through TV Picture

Check for AC power getting on the line. Use a ground breaker in line.
4. Ghost on the Picture

Check for low quality combiner/ splitter in system. Replace with high isolation combiner/splitter.
Check the type of coax used in system. Inadequate shielding in coax will cause ghosting.
5. Snowy Picture

Verify the modulator is set up for the proper TV channel band.
Verify the TV is set up on the proper TV channel band.
6. Black and White Lines on one Local Channel 

Move modulated channel up to a new channel. If problem persists and all of the inputs of a multiple input modulator are not being used, check default channels on modulator to see if default channel is set to the same channel that the problem channel is.

7. Modulated Picture is Too Bright or Washed out
   Adjust video level adjustment potentiometer on the modulator front panel or rear panel of chassis.
   If using a camera, check positioning of the lens to be sure it's not aimed at the sun or a reflection.
   Adjust camera lens.
8. Modulated Picture is Too Dark
  If the baseband video is being split, you might require a amplifier
   Try to adjust video level potentiometer on the front panel of modulator or rear panel of chassis
   If the video source is not being split, check input source directly into a TV
   Adjust the video level adjustment pot on the chassis of the set top units to the proper brightness.
9. Noise on the Audio
   Insert grounding block in line and ground coax cable before it enters the TV
   Use professional grade audio/video interconnect between the components and the modulator
10. Audio is Too Low 
  Use a Y connector to combiner the left and right audio before entering the modulator
