Note that the latencies within a Drive Module are equalized among outputs of that Drive Module.
That is, padding delay will be automatically added to some outputs such that the total latency is the
same in each output of a Drive Module.
This latency equalization does not extend outside a Drive Module, so Drive Modules are not
guaranteed to have the same latency as one-­‐another.
Secure Mode
When activated, this will disable all the front panel controls so they cannot affect the signal path,
making the unit secure against tampering. The only option that is left for user control is snapshot
recall. If this is not required then storing the same device state in every snapshot will effectively
disable this feature. When in secure mode, the indicators still operate normally. To activate secure
mode, press and hold the utility button for 5 seconds. To deactivate, press and hold the utility
button for 5 seconds. When in secure mode, this will be shown on the display. Note that the
Ethernet communications port is still active in secure mode.
Overlay Flush
If the device has been used in Module Groups, and still has an active Overlay (as indicated by the
Overlay indicator), these can be removed by simultaneously pressing and holding for 5 seconds the
Utility and Enter buttons. See
Overlays .
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 indicators 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.
