Amplification And Protection Circuitry; Dsp - K-array KN6 User Manual

8.7 AMPLIFICATION AND PROTECTION CIRCUITRY

The KN6 and KN10S are powered by the a multi channel high power digital amplifier.
KN6: 2 x 250W class D amplifier channel + 2 x 20W class A/B amplifier channel
KN10S: 2 x 250W class D amplifier channel
All the specific functions for the KN6 or KN10S such as crossovers, frequency, phase
response, and driver protection are determined by a DSP processor installed inside
the amplifier.
The devices have three different type of audio signal limiter. The Clip limiter, the
average Power limiter and the High Frequency limiter reduce the risk of damaging
the components of the speakers.
A Peak Current Shut Down acts as output stage switching process inhibition that
resets itself after 2 seconds. The tripping point is at 35A.
A temperature protection acts reducing the output stage gain above temperature
level of 85° (temperature on output power devices proximity).

8.8 DSP

The internal DSP allows to choice between four different default presets.
