Protection systems
Note: Under all circumstances the control and protection systems will endeavour to deliver the maximum power possible for a given
set of conditions, applying limiters only in extreme circumstances. Muting will only occur when a dangerous situation is detected,
normal operation automatically resuming when the condition clears.
System protection Speaker protection
Excessive output current Audio soft-clip limiter
Excessive power supply current VxLim, Multiband peak limiter
Excessive amplifier section temperature VxMax, Multiband overshoot limiter
Excessive power supply section temperature Vx-Xmax, Driver excursion limiter
Excessive DSP section temperature Vx-Tmax, Driver thermal limiter (long term power limiter)
Mains voltage out of range DC offset protection
Fan speeds out of range Excessive HF energy (VHF) limiter
Internal power rails out of range
Power distribution protection systems
Mains inrush current limiting (soft start and anti-surge)
Mains average current limiting (mains breaker / fuse trip protection)
Randomised initialisation when powered up to reduce the peak power demand in large systems
