4.1 Connecting to an Amplifier

1. Ensure your amplifier is turned off before making any connections.
2. Connect a speaker cable from the amplifier's output to one of the NL4 input connectors on the EKX15.
3. If connecting multiple passive speakers, you can use the parallel output connector on the EKX15 to link to another speaker. Ensure the total impedance matches your amplifier's capabilities.

4.2 Cable Requirements

Use professional-grade speaker cables with appropriate gauge for the length of the run and power requirements. Avoid using instrument cables for speaker connections.

2. Turn on your audio source (mixer, etc.).
3. Turn on your external amplifier.
4. Gradually increase the amplifier's volume to the desired listening level.

5.2 Powering Off

1. Decrease the amplifier's volume to minimum.
2. Turn off the amplifier.
3. Turn off your audio source.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your EKX15 loudspeaker.

6.1 Cleaning

Clean the cabinet with a soft, dry cloth. Do not use abrasive cleaners or solvents. The grille can be gently vacuumed to remove dust.

6.2 Storage

When not in use, store the loudspeaker in a dry, temperature-controlled environment. If transporting, use appropriate protective covers or cases.

7. Troubleshooting

If you encounter issues with your EKX15, refer to the following common troubleshooting steps:

• No Sound: Check all cable connections (speaker to amplifier, source to amplifier). Ensure the amplifier is powered on and its volume is up. Verify the audio source is active.
• Distorted Sound: Reduce the volume on your amplifier and audio source. Ensure the amplifier is not clipping (indicated by a clip LED). Check for damaged speaker cables.
• Intermittent Sound: Inspect all cables for loose connections or damage. Try swapping cables to isolate the issue.

If the problem persists after performing these checks, contact Electro-Voice customer support or a qualified service technician.
