 AARNRNG!:

 

Do not connect more than five KLA Series loudspeakers together using the loop-thru power cables (four loop-

thru cables, one AC power cord). If you are using loop-thru power cables, make all loop-thru connections prior to connecting to 
the AC mains.

3.  Insert the grey powerCON® connector, on the loop-thru cable, fully into the grey AC OUT connector 

(3)

 on the amplifier.

4.  Twist the powerCON® connector clockwise until it locks in place.

5.  Insert the blue powerCON® connector fully into the blue AC IN connector 

(4)

 on the next amplifier to be powered.

6.  Twist the powerCON® connector clockwise until it locks in place.

7.  Repeat until all of the loudspeakers (up to five loudspeakers, using four loop-thru cables) in the array are properly connected.

Connect AC Mains

Refer to 

Figure 30.

8.  Insert the blue powerCON® connector, on the AC power cord, fully into the blue AC IN connector 

(4)

 on the first amplifier in the chain.

9.  Twist the powerCON® cable connector clockwise until it locks in place.

10. Plug the other end of the power cable into the appropriate AC mains power source.

11. You may now turn on the AC power switch(es) using the Power-On procedure in this document.

Power-on Sequence

1.  Bring the output level control of the mixer (or other audio source) feeding your loudspeakers to its minimum position.

2.  Turn on all source devices (CD players, mixers, instruments).

3.  Push in on the top of the POWER rocker switch 

(Figure 30, 1)

 to apply AC mains power to the first powered loudspeaker in the signal chain. No 

other loudspeaker is feeding audio signal to this one.

4.  When the amplifier is turned on, the green STANDBY indicator LED and the red LIMIT indicator LED, on the amplifier panel, illuminate. After a few 

seconds the red LIMIT indicator and the green STANDBY go out, and the blue POWER indicator LED illuminates. Refer to 

Figure 31.

5.  Turn on the remainder of the KLA loudspeakers in the order in which they receive audio signal first to last.

6.  The level controls on your mixer may now be brought up.

Power-off Sequence

1.  Bring the output level control of the mixer (or other audio source) feeding your loudspeakers to its minimum position.

2.  Turn the KLA loudspeakers off, starting with the last loudspeaker in the signal chain, by pushing in on the bottom of the POWER switch (

Figure 

30, 1

).

3.  Turn off the remainder of the KLA loudspeakers in reverse of the order in which they receive audio signal — last to first.

4.  Turn off all source devices.

Disconnect AC Mains

1.  Use the 

"Power-off Sequence" on page 18

 procedure and turn the AC power switches to the off position.

2.  Unplug the power cable from the AC mains.

3.  Disconnect all AC loop-thru cables by grasping the powerCON® cable connector, sliding the latch button away from the amplifier, twisting the 

powerCON® connector counterclockwise, and pulling straight out from the amplifier.

4.  Remove the AC power cord by grasping the powerCON® cable connector, pressing down on the latch button, twisting the cable connector 

counterclockwise, and pulling straight out from the powerCON® chassis connector.
