PROTECTIONS
DC protection
Yes (protects loudspeaker and installation against DC and
infrasonic signals at the outputs)
HF protection
Yes (protects the loudspeakers against non-audible, strong,
non-musical high frequency signals)
Short-circuit protection
Yes (protects the amplifier from overcurrent, short circuit or
other stressful events for the output stages with output
reduction or MUTE (automatic protection reset)
Clip limiter
Yes (prevents severely clipped waveforms from reaching
loudspeakers, while still maintaining full peak power output).
Long term limiter
Yes (protects the loudspeaker and amplifier against steady
long term rms signals (sine wave, non-music) reducing
maximum output)
Thermal protection
Yes (output power reduction when output stages operating
temperature up to 90 °C (194 °F). Mute when output stages
operating temperature up to 100 °C (212 °F)
