Alcad MS-551 Bedienungsanleitung
Technote 2: Setting up MS-551 Stereo Modulators
Vestigial Side Band TV Stereo Modulators generate an analogue TV channel from the audio
and video signals .MS-551 Stereo modulators comprise SAW filtering for maximum harmonic
reduction and true VSB response for adjacent channel operation.
IMPORTANT: Layout of the modules must be as shown above. Power Supply (FA-310/312)
must be located on the far left hand side and launch amplifier (PA-720) must be the next
module in the chain. Please look at the above picture.

WHEN PROGRAMMING
Programming of Modules
Ensure the following prior to programming:
•It is necessary to connect all the modules to the support frame SP-226 (code 9120130)
for the system to function.
•It is also recommended that you make the earth connection to the building using a cable
with a section of at least 4 mm.
•Ensure that you have the Alcad programmer PS-003 with firmware version 4.7 or later.
•Power supply/Control cable must be plugged into each module. DO NOT ADD OR
REMOVE modules without disconnecting mains supply power from wall outlet. Always
disconnect the equipment, and then reconnect it to the mains supply so that the
amplifier recognises the new module. Failure to do so can cause equipment to fail.
Launch Amplifier
Power Supply
The MS-551 modulators use an 8 pin Mini-Din cable that is available from your local ALCAD
dealer. The mini DIN connection is located on the front of the modulator. Please look at picture
below for example.
In connecting the audio and video sources, two types of cables are available:
•CD-003 (cod. 9120098) Stereo, with a miniDIN to SCART (EuroConnector) connection.
•CD-113 (cod. 9120094) Stereo, with a miniDIN to RCA connection.
1.0 Programming of the Modulator
To program the modulator, place the programming switch in the ON (upward) position which
can be seen from picture below. When you turn the switch in the “ON” position the
programming indicator will light up. While the programming indicator remains lit, the channel
processor is ready to receive data from the PS programmer. When the modulator has been
programmed, programming mode should be deactivated by placing the switch in the OFF
position. The programming indicator light will go out.
To start programming the equipment, Press any button on the PS-003 programmer to turn on
the programmer. The following screenshot below will appear.
You must then select the model you are trying to program. Scroll left or right using
the arrows until you get screenshot below
You will then need to press arrow down and you will then see the screen “Table
channels B/G CCIR“on the programmer screen. This can be seen below
Press the left arrow once so that you can see the screen shot as below “Table
channels frequency”.
Press the arrow down once which will take you to “Output Frequency” screen.
Increase/decrease the values using the arrows or use the numeric keypad to enter
the frequency output that is desired. Ensure if you enter the value using the numeric keypad
you use the decimal point. The Australian Analogue/Digital frequency table can be seen on the
next page
Once you have the desired output frequency press transmit and you will see the PRG
LED on the processor you are programming flash twice. This indicates it is receiving the
settings from the programmer. Now press down arrow to get to the next screen below.

The next screen enables the type of Audio output that is to be selected stereo or mono
Once you have the desired audio output press transmit to ensure setting is sent to
module, then press the down arrow to go to the next screen below.
The “Audio level” screen enables manipulation of the Audio Sub-carrier from the modulator.
Once you have the desired audio level set press transmit to ensure setting is sent to
module, then press the down arrow to go to the next screen below.
The “Video level” screen enables manipulation of the Video-carrier from the modulator. Once
you have the desired video level set press transmit to ensure setting is sent to module,
then press the down arrow to go to the next screen below.
The “V/A ratio” enables 12dB or 16dB ratio settings, which is the difference between the
Video to Audio carriers. Once you have the desired V/A ratio set press transmit to ensure
setting is sent to module.
The modulator has now been programmed; programming mode should be deactivated by
placing the switch in the OFF position. The programming indicator light will go out.
Ensure to set power level of each module using the Phillips head variable gain controller.
