Introducing five incredible new amplifiers, all made in the United States of America. Orbiting Planet Audio are
three high-power 2-Channel amplifiers, one high-power 4-Channel and a monoblock amplifier.
I
This series of Planet Audio amplifiers has been built and tested to the highest standards. These amplifiers follow a
"Zero Compromise'' design philosophy. The built-in features permit them to accommodate almost all installation
situations. The heat sinks are truly massive, weighing almost twice as much as would be required for their power
categories. When you review the features and specifications for these amplifiers, you will agree that these new
amplifiers from Planet Audio set a new standard of excellence for car audio performance.

Fully-complementary Class A voltage amplifiers are locally degenerated, and drive the

important note about these
amplifiers:
Because the power supplies are so highly regulated, it is important not to condect speakers whose impedance
is less than
2
Ohms/Channel(4 Ohm in bridged mode for Nebula, Vortex, Zetar
and
Quadra).
These amplifiers draw large amounts of went. Under normal conditions, the rated fuse is sufficient. However,
if
the amfilifiers
are
con
nel, and the fuse blows with continuous loud
material, then upgrade
