Protection Systems
Comprehensive protection features preserve the longevity of the loudspeaker and amplifier by continuously monitoring several
critical parameters, and reducing the gain, or muting the amplifier either temporarily or permanently depending on the nature
and seriousness of the fault or misuse. The amplifier will recover and restart if at all possible but may remain in shut down if a
serious fault persists.
Limiters deal with routine over‐driving of the amplifier, making sure that the driver(s) are not pushed too hard. The limiter
indicator(s) will warn you when the driver is being driven into limit.
Minor faults are dealt with by 'dimming' the amplifier, reducing the level to a sufficient degree and for a sufficient time that the
amplifier is able to recover gracefully without any user interaction. When the fault condition has passed, the amplifier will recover
automatically.
More serious faults may cause the amplifier to mute while it recovers, after which it will automatically re‐energise, again without
user interaction. If such a fault is found to be persistent however, the amplifier is shut down permanently. A power cycle by the
user is then required.
