Ya Gotta Know When to Kool It!
Your K-Series amplifier has been designed from the ground
up to be a high-output amplifier that is totally convec-
tion cooled—meaning no fan is required. This goal
was achieved through a variety of means:
First, we forgot to include the fan in the bill of materials.
Second, our balanced-current circuitry produces
power much more efficiently than conventional ampli-
fier circuits. Third, the amplifier case and front panel
were designed for increased airflow and superior heat
dissipation.
The smoothly molded front panel was also designed to allow
the center of gravity to be moved forward, placing it closer to
its mounting axis. While providing strength and rigidity, the die-
cast panel also protects the front panel controls and indicators
from inadvertent abuse.
Until now, all professional audio systems had either internal or
external auxiliary air systems facilitating the cooling of the elec-
tronics. With the K-Series, we have made fans unnecessary
for normal operation!
If you are operating the K-Series amp in very high ambient
temperatures, or if you notice theTLC indicators starting to illu-
minate, do not despair! Modest amounts of air movement will
enable your amp to dissipate any excessive heat and regain
its normal composure.
Under worst-case operating conditions, the K-Series amplifier
only dissipates the same heat as two100-watt lightbulbs. This will
be hot to touch, but even in such extreme conditions, your K-Se-
ries amplifier will not suffer any ill effects. That's because the K-
Series amplifiers contain TLC (thermal level control) systems that
will begin to decrease the gain of the amplifier if the TLC indica-
