POWER
LED
The MDA20 Series amplifier is based on a new
concept of convergent technology. The characteristics
of the IC selected provide a noise figure that is lower
than any other product currently on the market and
an output figure that surpasses most distribution
amplifiers hence the name Masthead Distribution
Amplifier (MDA).
The MDA20 Series are multipurpose amplifiers
that are ideal for our digital environment. Whether
the units are used as a Masthead or Distribution
Amplifier the low noise figure, capacity for multiple
channels with low distortion and a high output
provides a solution to all installations and is proven
especially effective in digital problem reception areas.

TECHNICAL ADVICE
1. Check if the power is reaching the amplifier.
Unscrew two screws holding the alloy cover
and check if the LED is on.
2. Check the orientation of the injector is
correct on the power supply.
3. Is there more than one outlet?
Check the splitter box, the power supply must
be connected to the coaxial outlet that feeds
the AC/DC leg of the splitter box to pass
power to the head unit. (Check if LED is on).
