CAUTION:
Electronic limiters cannot provide absolute protection against driver failure. Thus,
if limiting is occurring, it is a warning that excessive signal levels are being approached. It is
NOT an indication that the loudspeaker is successfully protecting itself.

AMPLIFIER STATUS
The AMPLIFIER STATUS indicator monitors the status of each of the two amplifiers in the full-
range and subwoofer models. If illuminated green, the amplifier is in NORMAL status. If
illuminated red, a protection circuit has activated and the amplifier is in FAULT status.
The causes for a FAULT indication can be:
•
Amplifier overheating
•
Power supply overheating
•
Excessive amplifier output current
•
Excessive power supply current
•
Low AC mains voltage
•
Low amplifier output voltage
•
Electronic failure
To minimize audio downtime or operation at reduced levels, the protection circuits will
automatically reset after the fault condition is lowered to an acceptable level or is removed. In the
event of protective shut-down due to electronic failure, there is no automatic reset. In this case the
amplifier must be serviced or replaced.

SIGNAL PRESENT
The SIGNAL PRESENT indicator illuminates when an audio signal greater than -30 dBu (25 mV)
is present at the input connector.

GRILLE MOUNTED LED

NT
/KFnt loudspeakers include a white LED in their front grilles. This LED has a number of
functions.
1. Blinks three times in response to the Identify function in EAWPilot. This behavior is
enabled by default.
2. Illuminates at power-up for a period of 60 seconds, then turns off. This behavior is
enabled by default.
3. Blinks once per second to indicate a fault in the amplifier assembly due to a problem
with one or both amplifier channels or with U-Net. This behavior is disabled by default.
4. Flashes in response to the limiter engaging to protect the loudspeaker. This behavior is
disabled by default.
5. Flashes in response to a clip condition in the amplifier assembly. This behavior is
enabled by default.
All of the above behaviors can be independently enabled or disabled using EAWPilot.

EQUALIZATION
The EAWPilot software application provides access to standard, user-adjustable DSP functions to
modify the overall performance of the array to accommodate a particular program content, venue
characteristics, or personal taste in voicing. These include low-pass filter, high-pass filter, shelving
and parametric EQ, gain, delay, and polarity. It also provides access to signal routing (Input Select
