Cooling
Fan (Forced air, front to back airflow. Temperature
controlled continuously variable speed)
Maximum fan nois
e
46 dB (Maximum acoustical noise @1m)
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))
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))
