en 4 11 Tripod and floor monitor operation Tripod or pole mount EKX-12 and EKX-15 loudspeakers mount on a tripod stand or on a pole above a subwoofer. Mounting a loudspeaker on a tripod stand Figure 4.1: Full-Range model on a tripod stand Caution! ! Tripod is not evaluated for safety with this loudspeaker. Check the specifications of the tripod stand to be certain it is capable of supporting the weight of the loudspeaker.
EKX Passive Loudspeakers Mounting a loudspeaker on a pole Figure 4.2: Full-Range/subwoofer stack with pole mount Caution! ! Two (2) person lift and placement is recommended for the heavier loudspeakers. Single person lift and placement of heavier loudspeakers could cause injury. To mount a loudspeaker on a pole, do the following: 1. Place the subwoofer on a level stable surface. 2. Insert the M20 threaded pole into the combo pole cup on the top of the subwoofer. 3.
en 13 Floor monitor EKX-12 and EKX-15 loudspeakers may be used as a floor monitor by placing the loudspeaker on the integral monitor angle. To set up a loudspeaker as a floor monitor, do the following: 1. Place the loudspeaker on a level stable surface. 2. Safely route cables to prevent injury to performers, production crew, and audience members. Notice! Secure cables with wire ties or tape whenever possible.

EKX Passive Loudspeakers 5 Suspension The EKX-12 and EKX-15 enclosures have eight (8) M10 threaded points; six (6) points on top of the enclosure and two (2) points on the bottom. Forged shoulder eyebolts rated for overhead suspension may be used to suspend an individual loudspeaker, such as the EBK-M10 accessory.
en 15 Installing the eyebolts To install the eyebolts, do the following: 1. Remove the M10 screws from the suspension points. 2. Replace the M10 screw with the fender washer and eyebolts. Notice! If the eyebolts are removed reinstall the screws. If the screws are not reinstalled air leaks occur in the enclosure, resulting in undesirable performance. Electro-Voice User Manual 2015.01 | 01 | F.01U.308.
EKX Passive Loudspeakers Warning! ! Eyebolts must be fully seated and oriented in the plane of pull. Always use fender washers at least 1.5 inch in diameter and 1/16 inch thick under the eyebolt to distribute the load on the enclosure. Figure 5.2: Eyebolt shown with and without washer Figure 5.3: Eyebolts shown oriented in the plane of pull 2015.01 | 01 | F.01U.308.

en 21 Troubleshooting 7 Problem Possible Cause(s) Action 1. Amplifier Connect a known working test loudspeaker to the No sound amplifier outputs. If there is no sound, verify all the electronics are on, the signal routing is correct, the source is active; the volume is turned up, etc. Correct/repair/replace as necessary. If there is sound, the problem is in the wiring. Wiring Verify you have connected the correct cables to the amplifier. Play something at a low level through the amplifier.
