What to do if Electro-Voice EKX-18SP sound distorted?
To prevent distortion, reduce the input level or loudspeaker level knobs if the front LED is OFF and the LCD screen LIMIT is ON, indicating excessive input level.
How to stop acoustic feedback from Electro-Voice EKX-18SP Speakers?
If your Electro-Voice Speakers produce acoustic feedback, try the following: * Reduce the microphone levels at the mixing console or input source. * If the microphone is connected directly to the speaker, reduce the input level on the speaker. * Position the microphone closer to the sound source. * Change the MODE to LIVE or SPEECH. * Position the loudspeakers so the microphone is behind them or, if using the loudspeaker in a monitor position, aim the loudspeaker to the back of the microphone.
Why are my Electro-Voice EKX-18SP Speakers making a constant noise?
If you experience constant noise (buzzing, hissing, or humming) from your Electro-Voice Speakers, and no program material is playing, evaluate each component to isolate the problem. There is most likely a break in the signal path. Also, check and correct the system grounding, as required. Ensure the input gain knob is in the MIC position and slowly increase the input gain knob level to engage the microphone pre-amp.
Why do my Electro-Voice Speakers have no sound?
If your Electro-Voice Speakers produce no sound, verify all the electronics are on, the signal routing is correct, the source is active, and the volume is turned up. Correct/repair/replace components as necessary. If there is sound, the problem is wiring. Verify you have connected the correct cables to the amplifier. Play something at a low level through the amplifier. Connect the test loudspeaker in parallel with the malfunctioning line. If the sound level is gone or is very weak, the line has a short in it. Using the test loudspeaker, move down the line and test each connection/junction until you find the problem and correct it. Observe proper polarity.
How to unlock the DSP menu on Electro-Voice EKX-18SP?
If the DSP menu on your Electro-Voice Speakers is locked (a lock symbol displays on the LCD screen), press and hold the MASTER VOL knob for 5 seconds to unlock it.
What to do if Electro-Voice EKX-18SP Speakers have intermittent output?
If your Electro-Voice Speakers have intermittent output (such as cracking or distortion), check all connections at the amplifier and loudspeakers to ensure they are clean and tight. If the problem persists, check the wiring. Verify you have connected the correct cables to the amplifier. Play something at a low level through the amplifier. Connect the test loudspeaker in parallel with the malfunctioning line. If the sound level is gone or is very weak, the line has a short in it. Using the test loudspeaker, move down the line and test each connection/junction until you find the problem and correct it. Observe proper polarity.
Why is there no sound from the microphone on Electro-Voice Speakers?
If no sound is produced when a microphone is connected to INPUT 1 or INPUT 2 on your Electro-Voice Speakers, use a dynamic microphone that does not require phantom power. If using a microphone requiring phantom power, an external phantom power source is needed. Also, slowly increase the input gain knob level to engage the microphone pre-amp.
How to improve low-frequency response on Electro-Voice EKX-18SP Speakers?
If your Electro-Voice Speakers have poor low-frequency response, and the SUB menu cross-over frequency is activated, but no subwoofers are used with the system, select the OFF position.
Why is there no sound coming from my Electro-Voice EKX-18SP?
If your Electro-Voice speakers produce no sound, there are several possible causes: * **Amplifier Issues:** To check this, connect a working test loudspeaker to the amplifier outputs. If there's still no sound, ensure all electronics are on, the signal routing is correct, the source is active, and the volume is turned up. Correct, repair, or replace components as needed. * **Wiring Problems:** Verify you've connected the correct cables to the amplifier. Play audio at a low level through the amplifier, and connect the test loudspeaker in parallel with the malfunctioning line. If the sound disappears or is very weak, the line likely has a short. Use the test loudspeaker to check each connection/junction until you find the issue and correct it, ensuring proper polarity.
What to do if my Electro-Voice EKX-18SP have constant buzzing, hissing, or humming?
If your Electro-Voice speakers are emitting constant noise such as buzzing, hissing, or humming, consider these potential causes and solutions: * **Defective Source or Electronic Device:** If the noise persists when no program material is playing, evaluate each component to isolate the problem. A break in the signal path is likely. * **Poor System Grounding or Ground Loop:** Check and correct the system grounding as required. * **Input Gain Knob Position:** Ensure the input gain knob is in the MIC position. Slowly increase the input gain knob level to engage the microphone pre-amp.
