Front LED 

(not shown)

The front LED may be set to any of three modes by the FRONT LED switch on the rear panel.

• From the factory, the FRONT LED switch is set to the PWR position. The front LED illuminates brightly when the POWER switch is in the ON position.
• When the FRONT LED switch is in the OFF position, the front LED is not illuminated. This setting is recommended in applications where the front LED may be visually objectionable.
• When the FRONT LED switch is in the LIMIT position, the front LED tracks the LIMIT LED on the rear panel. When the KW Series is in limiting (meaning that one or more of the limiters is engaging to protect some part of the system) the front LED glows brightly in response to the limiting function. This allows the system operator to have awareness of the status of the limiters without needing to see the rear of the unit. For more information see the section below on the rear LIMIT LED. When not in limiting and when the unit is not in standby, the front LED is dimly illuminated.

The red LIMIT LED can indicate that limiting has taken place to protect and avoid damage to the amplifier or loudspeaker. If the signal level at any frequency is too high, the DSP limits the signal to prevent damage and the red LIMIT LED illuminates. If the amplifier is too hot due to prolonged use at extreme SPL levels or the environment is too hot, the red LIMIT LED is illuminated. If the red LIMIT LED is on when both GAIN controls are at minimum for 10 minutes, your KW Series loudspeaker requires service by qualified personnel or should be moved to a cooler environment.

All KW Series models are equipped with an automatic standby feature to conserve energy when the systems are not in use. If no signal is present on any input, or the gain knob is turned to off for five minutes, the power amplifier goes into standby and the green STBY LED illuminates. In this mode, the amplifier is powered down. A small amount of current will continue to flow from the AC power source into the power supply of the KW Series. This current keeps the power supply and DSP “awake” to reduce turn on time when the system is brought out of standby. The power-up time of the amplifier is negligible and is shorter than the latency of the DSP, so no signal is cut off when the KW Series system is brought out of standby. A KW Series loudspeaker can also be manually brought out of standby by turning the POWER switch off and then back ON.

The blue POWER LED on the rear panel illuminates when: the AC mains are functioning properly, the AC mains power cord is connected properly, the POWER switch is in the ON position, and the unit is not in standby. The rear POWER LED extinguishes when the AC mains power cord has been removed from the loudspeaker or source, the POWER switch is in the off (not ON) position, or the amplifier enters standby

When illuminated (yellow) it indicates the input is configured to accept a microphone input. When not illuminated, it indicates the input is configured for a line-level input. You can change the setting through the Menu. When MIC is selected, the MIC Pre-amp is activated, and the yellow MIC level LED illuminates. The MIC setting should only be used if a microphone is connected directly to the MIC/LINE input. 

The green SIGNAL LED illuminates when a signal is present at either input, regardless of the amount of gain as set by the GAIN knob. If the LED does not illuminate, the input is not receiving any signal, or the level of the signal is too low. Check all connections and the status of the device delivering the signal.
