Introduction 5
The KA KA KA KA KA -Series amplifiers are 2 unit (3.5") tall, 19"
wide rack mountable units.
Each channel of the amplifier comprises a balanced
active input with a buffered attenuator driving a
differential class A drive stage which in turn drives a
fan-cooled, class AB, MOSFET output stage
configured as a source follower. The unit operates
from a high current-capable linear power supply.
These units have been specifically designed to deliver
their high power output with minimal distortion, and
provide the critical degree of control required by your
speakers, at high duty cycles for extended periods.
