CLIP
The CLIP LED display lights up when the relevant amp channel is operated in the upper threshold range. Brief illumination of the LED is uncritical here. In order to protect the system, an excessive signal level is gently down- regulated by the integrated limiters. If the CLIP LED lights up for a prolonged period or permanently, reduce the volume level. -
PMS (POWER MANAGEMENT SYSTEM)
The PMS is an electronic protection system that permanently monitors the main amp parameters so as to only draw from the power supply the amount of current required to maintain safe operation (monitoring of
signal input, capacity, temperature, current). The PMS LED lights up in the following situations:
During the power-up process until the amp is fully functional. The outputs are muted at the same time.
Due to unfavorable operating conditions, the internal temperature rises to near the point when the system would automatically shutdown to prevent overheating. Here the system takes control, restricting current so as to maintain operational continuity at the power level which the amp is capable of withstanding at that particular moment.
Excessive mains current consumption. This only occurs either under laboratory conditions during protracted sinusoidal signal testing using dummy loads or in conditions of prolonged acoustic feedback. Here the PMS takes control to avoid any damage to the speakers and to prevent the mains breaker from tripping or the fuses blowing. -
