3.3 Protection Systems
ICL2 ™ . - Intelligent Clip Limiter
The ICL2 is an anticlip system to avoid speaker failure and provide more acceptable sound quality even when
clipping occurs. With the ICL2 system you don’t lose the music .punch. but the speakers are kept under
control.
PMS ™ . - Power Management System
This is a complete set of protections that monitors the main amp parameters (load status, signal input,
temperature, current, etc.) in order to draw from the power supply only the precise amount of current required
to maintain safe operation during hazardous or extreme working conditions.
This system controls the amount of power that the amp delivers under three basic circumstances:
1.- The power-on sequence, where output is inhibited until the amp 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 near thermal shutdown point due to unfavourable operating conditions.
Here the system takes control, restricting current so as to maintain operational continuity at the precise power
level which the amp is capable of withstanding at that 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 field applications in conditions of prolonged
acoustic howl-round. Here PMS takes control to avoid any damage to the speakers and to prevent the mains
breaker from tripping or the fuses blowing.
SSP ™ . - SOA Sentry Protection
SOA Sentry protection effectively limiting the power that the amp could deliver into an incorrect load or to a
direct short-circuit. This avoids power transistor failure.
WARNING:
The exclamation point inside an equilateral triangle indicates the existence of internal components whose
substitution may affect safety.
The lightning and arrowhead symbol warns about the presence of uninsulated dangerous voltage.
