PROTECTION
SYSTEMS:
PMS™ - POWER MANAGEMENT SySTEM
This is a complete set of protections that monitors the main amp parameters (load status, signal input, tempera-
ture, 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.
ICL2™ - INTELLIGENT CLIP LIMITER
The LD PREMIUM 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.
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.
