1 Description
The X-A/V quad is used to modulate four audio and/or
video sources and convert them into standard TV signals
in the frequency range from 47 – 862 MHz. The card has
two output converters which belong together, which
means that up to four A/V signals can be processed in
pairs and converted to two pairs of adjacent channels. All
four output channels can be switched on and off inde-
pendently of each other. The levels of the individual
boards are equalized via the HE programming software
or the KC 3 handheld programming device. The X-A/V
quad can only be used in combination with the V16 and
X-8 twin base units, as these have the necessary moun-
ting hardware for the input jacks (a full complement of X-
A/V quads can only be installed in combination with the
V16.13/X-8 twin base unit, otherwise a maximum of only
two X-A/V units is possible).
The video signals which are to be fed in must comply
with the FBAS standard (PAL/CCIR 405-1) and have a
level of 1 Vpp. It is extremely important to ensure that
this level is met exactly, as no level control is provided.
In addition, when setting up the plug-in card and starting
to use it for the first time, make sure that all channels
have the same output level and that they are matched
to any existing systems.
Please note:
These modules must only be replaced or exchanged
by an authorized specialist who has been certified
by the Chamber of Commerce and Industry (master
workshop). The hazard warnings and safety precau-
tions contained in the operating instructions of the
base unit and the relevant safety regulations accor-
ding to DIN VDE regulation 0701, part 1 and 200,
must be followed.

2 Installation and connection
2.1 Installation in the base unit
Install the plug-in card in accordance with the descrip-
tion.
Important:
The X-A/V quad must not be used in conjunction
with any other base units than those listed above.
Remove the covers from the
base device (plug-in card slot)
and insert the supplied female
connectors. Check that the
post connectors are correctly
positioned on the plug-in card
and on the adapter PCB..

3 Programming with the HE programming
software
Once it has been installed in the base device, the X-A/V
quad card can be programmed with the HE program-
ming software. After the base unit has been read out,
the overview window of the base unit will show the X-
A/V quad card on the slot on which it is installed.
2.2 Connection of source devices
A VCP 15-2 connecting cable (order no.: 350151; 1.4
m) is required in order to connect an A/V audio source
device, such as a DVD player, camera etc. The cable
has a 15-pole Sub-D connector at one end and 2x 3-
way Cinch/RCA connectors at the other end.

As there are four different output channels, the RF-
output parameters are defined in the card details rat-
her than in the overview window of the base unit.
To access this screen, click on the “Details” button.
All settings relevant for operation of the module are
made here.
In the “Input parameters” field you can enter the pro-
gram name. Under the output parameters you can
activate or deactivate the output channel and define the
audio mode (Stereo, Mono or 2-channel).
The output channel is also defined at this point. Please
note that by defining the A channel for a pair of chan-
nels you are also defining the B channel as its adjacent
channel.
The allocation of output channels is shown in the
“Channel Overview” window:
Double-click in this window to switch between the
channel allocation and the frequency overview.
The X-A/V card is provided with electronic level equa-
lization. This means that the output level is set via the
HE programming software and not via a level adjuster.
The “Level control” button activates this function.

Here you can attenuate the output level in steps of
0.5 dB.
After an attenuation value has been selected, it must
be transferred to the card by clicking on the “Write
parameters” button. If the values are not known then
they can be read out and displayed via the “Read
parameters” button.
4 Programming sequence
4.1 Structure
The software is divided into two main groups.
1) Start menu
The software version number is displayed.
Please quote this version number whenever contac-
ting our customer service department.
The Start menu can only be accessed again later on
by unplugging and replugging the KC 3.
2) Programming the channel-specific parameters
The channel-specific parameters are programmed in
two menus.
Line 1: Menu Select plug-in card slot/channel
group
Lines 3+4: Menu RF output data
(modulator parameters)
In general, the programming sequence should follow
the hierarchy of the lines, i.e. start by
•selecting the plug-in card/channel group (line 1),
then
•enter the RF parameters (lines 3+4) for the plug-in
card.

4 Programming with the KC 3 4 Programming with the KC 3

The RF output parameters are defined either by ente-
ring the video carrier frequency directly using the key-
pad (row 3), or by changing the output channel value
(line 4) step-by-step with the ←or →cursor keys.
Please note:
As both channel pairs are converted jointly by one
modulator, the output frequencies of one channel pair
must not be adjusted independently of each other. The
frequency specified in channel A of a group is always
decisive; channel B is automatically assigned an offset
corresponding to the channel configuration.
Accordingly, the output frequency should always be
adjusted via the channel selection in row 4. This ensu-
res that the video carrier automatically receives a fre-
quency which corresponds to the channel
configuration.
With the cursor in the third row, click on the “Menu /
Read” button to open the
Audio mode selection menu.
Use the ←or →cursor keys to change the audio mode.
You can choose from Mono, Stereo or 2-channel
sound. Press the “Menu / Read” button again to go to
Activation and deactivation of the output signal:
Use the ←or →cursor keys to activate or deactivate
the output signal.
4.2 Moving between menus
•Use the ↑and ↓arrow keys to change between
rows.
•Press the MENU button to change between sub-
menus in a row.
4.3 Entering parameters
•Enter values directly via the keypad, or
•Adjust the pre-defined parameters (e.g. Sat level)
in steps using the ←or →cursor keys.
Important:
•The numerical values must be entered in full.
4.4 Saving
•Once all entries are complete the parameters need
to be saved so that they are adopted (i.e. set) by the
card and are protected against data loss in the event
of a power failure.
•Save the parameters separately for each channel
group.
Press the STORE button to save the set parameters.
4.5 Programming the card-specific parameters
Once you have reached the required slot / channel
group by pressing the ←or →cursor key in line 1 and
then selected line 3 or 4 with the ↑or ↓cursor key you
will come to the menu for
Defining the RF output parameters.

Setting the output level:
On the X-A/V quad, the level is equalized electronically.
The RF level can be attenuated in steps of 0.5 dB
using the ←or →cursor keys.
As was already mentioned in point 4.4, it is essential
that any changes are saved.
