Protection System
Each Kryo amplifier features a complete protection system that monitors the
main amplifier parameters (load status, signal input, temperature, current etc)
The system controls the amount of power that the amplifier delivers under three
basic circumstances.
1. The power on sequence, where the output is inhibited until the amplifiers
circuits are ready to operate. This routine is repeated at every restart, not
just when the power switch is activated.
2. When internal temperatures rise to the near thermal shutdown point due to
unfavourable operating conditions. Here the system takes control, restricting
current to maintain operational continuity at the precise power level at which
the amplifier is capable of withstanding at the particular moment.
3. Excessive mains current consumption. This event only occurs either under
laboratory conditions (long term sinusoidal signal testing with dummy loads)
or, for example, in conditions of prolonged acoustic feedback. Here the
protection system takes control to avoid any damage to the speakers and to
prevent the mains breaker from tripping or the fuses blowing.
ICL Intelligent Clip Limiter
The Kryo series of amplifiers use an intelligent anti clip system that differs from
conventional clip reduction systems. The system dynamically tracks the power
rail values to provide instant current/voltage limiting, this eliminates any limiting
of the signal dynamics. More like a valve amplifier, the ICL system maintains
sonic transparency even when the amplifier has exceeded the threshold of
clipping, providing very high dynamics at negligible distortion levels.
The default setting for the limiters is on, and it is recommended that the anti clip
limiters be left in the on position.
