TV-amplifier A 3240
A 3240 broadband TV amplifier covers all
international TV-frequencies. It is intended
for use in smaller CAS-systems. The automatic Level Control (ALC) circuit sets the
output signal to an appropriate level
protecting receivers from overloading in
areas close to transmitters. The amplifier
is constructed with a hybrid circuit in the
front-end followed by three epitaxial
transistors assuring high intermodulation
suppression and low noise. The gain can
be set by a 20 dB attenuator.
The automatic level control (ALC) function is indicated by the front panel LEDs.
The green LED is lit when the ALC is off
and max. gain is available. The two red
LEDs indicate ALC in action in the lower
or higher attenuation level.

Since 1971, the objective of Naval Electronics has been to
offer the best possible products for TV and Radio reception
at sea. Naval began with omnidirectional antennas and is the
world leader in this field of technology today. Now, with an
expanded product range, the name Naval means much more
than antennas. Naval operates in more than 40 countries and
has installations on thousands of vessels all over the world.
