MDL 100 LINE MULTIPLIER AND SWITCHER
The MDL100 unit converts the standard TV signal into a high resolution
RGBHsVs graphic signal. It can be used to enhance image quality in the
case of video projection or display on monitor. The possibility of selecting
between 4 video inputs with related associated audio make the MDL100
very useful in multi-media presentations.

software is furnished with the unit.
4.0 INSTALLATION
a) Make sure that all the units to be installed are off.
b) Connect the
Pal sources to the two BNC identified as IN1 and IN2
c) Connect the
Y/C source to the mini-DIN connector identified as IN3
d) Connect the graphic source (PC) to the HDD15p.m. connector identified as IN4
WARNING
If more than 1 computer is to be connected to the system,
use a TZW403 type switcher connecting the
output of this to the IN4 input of the MDL100
e) Connect the destination (video projector or multiscan monitor) to the HDD15p.f.
connector identified as OUT using an ADC105 type high quality multi-coax cable.
WARNING
If the cable is more than 10 meters long,
it is advisable to insert an INBOX/4 type amplifier
f) Connect the stereo audio leading out of the 4 sources to the four 3.5mm jack outlets
identified as AUDIO L+R 1÷4
g) Take the stereo audio leading out of the OUT jack outlet and connect it to the sound
amplification and diffusion system.
h) If required, connect the control PC or the external control dry contacts as described
in chapters 7.0 and 8.0.
i) Connect the Vac power supply as specified in chapter 2,0 and check that the led of
the key referring to input 1 on the front of the unit lights up.
j) Power the sources and destination. The source connected to input IN1 must be
displayed in high resolution.
5.0 SOURCE SELECTION The sources are selected pressing one of the 4 keys
identified as INPUTS 1-4 on the built-in console of
