Features
Your new Atlantic Technology Multi-Channel Amplier is a state of the art, high
performance audio device. It is built utilizing totally complementary circuitry
from input to output. The high current power supplies are driven by custom-
designed toroid transformers which reduce hum and noise signicantly.
Each of the seven amplier modules incorporates 2 very high quality dis-
crete output devices capable of passing in excess of 20 amps of current. The
amplier’s circuitry is both very sophisticated in concept yet simple in layout
and construction. A minimum number of components are used in the signal
path to ensure excellent sound quality and reliability. These components have
been chosen for their ability to amplify the signal while adding or subtracting
nothing to/from the sound.
The advanced protection circuits (over-current, over-temperature, DC
offset)are external to the signal path and therefore don’t degrade the ampli-
ed signal in any way. No current or voltage limiting are employed to further
ensure signal purity and guarantee substantial dynamic range. Heat manage-
ment is provided by custom-designed cast aluminum heat sinks that also
form the sides of the amplier itself. The heat sinks have been “overspeced”
to ensure cool running and long life for the internal components, as heat is
the prime enemy of electronic parts.
Unpacking
The carton and packing materials used in shipping your new amplier were
specially designed to cushion it from the shocks and vibration of shipping. We
strongly suggest that you save the carton and packing materials to use if you
move, or if the unit ever needs to be shipped for any reason. To minimize the
size of the carton in storage, you may wish to atten it by carefully opening
the top and bottom aps and folding the carton at. Other cardboard inserts
may be stored in the same manner. Packing materials that cannot be collapsed
should be saved along with the carton in a plastic bag.
Your new amplier has been engineered using heavy duty materials for high
reliability and weighs a considerable amount (67 pounds). This substantial
weight requires that you pay special attention to unpacking and installation
of the unit. You may wish to have someone help you remove the unit from
its carton and place it in your chosen location.
