1 Welcome

Congratulations on purchasing a Crown
K Series amplifier. It is designed to provide very
high power in a lightweight package, without
using a cooling fan. This means your amp runs
quieter (no fan noise) and cleaner (no need for
filters). The K Series amplifiers are very energy-
efficient as well.
Modern power amplifiers are sophisticated
pieces of engineering capable of producing
extremely high power levels. They must be
treated with respect and correctly installed if
they are to provide the many years of reliable
service for which they were designed.
In addition, the K Series amplifiers include a
number of features which require some expla-
nation before they can be used to their maxi-
mum advantage.
Please take the time to study this manual so
that you can obtain the best possible service
from your amplifier.

1.1 Features

• Accurate, uncolored sound with very low
distortion.
