4.2 Initial Placement

Position the Electro-Voice EKX loudspeakers on their stands, ensuring they are stable and at an appropriate height for your audience. Place the EKX subwoofers on the floor, ideally centered or symmetrically placed relative to the main loudspeakers for optimal bass distribution. The Yamaha MG16XU mixing console should be placed on a stable surface within easy reach of the operator, away from excessive heat or moisture.

4.3 Power Connections

1. Ensure all equipment is switched OFF before making any power connections.
2. Connect the provided power cables to the power inlets of the EKX loudspeakers, EKX subwoofers, and the Yamaha MG16XU mixing console.
3. Plug the other end of the power cables into grounded electrical outlets.
4. Do not power on any equipment until all audio connections are complete.

4.4 Audio Connections

1. Mixer to Subwoofers: Connect the MAIN STEREO OUT (XLR) of the Yamaha MG16XU mixing console to the INPUT (XLR) of the EKX subwoofers using XLR cables. If using two subwoofers, connect the Left output to one subwoofer and the Right output to the other.
2. Subwoofers to Loudspeakers: Connect the THRU/OUTPUT (XLR) of the EKX subwoofers to the INPUT (XLR) of the EKX loudspeakers. This allows the subwoofers to pass the signal to the full-range loudspeakers.
3. Microphones to Mixer: Connect the microphones to the XLR INPUTs of the Yamaha MG16XU mixing console using XLR cables. Use channels 1-3 for the microphones.
4. Bluetooth Receiver to Mixer: Connect the Alto Professional Bluetooth Receiver to an available stereo input channel on the Yamaha MG16XU mixing console (e.g., channels 15/16 or a dedicated stereo input) using appropriate cables (e.g., XLR to 1/4" TRS or RCA to 1/4" TRS, depending on the receiver's output and mixer's input).

5. Operating Instructions

5.1 Powering On/Off Sequence

To prevent damage to your equipment and unpleasant pops/clicks, follow this power sequence:

1. Ensure all volume controls on the mixing console and loudspeakers are turned down to their minimum.
2. Power on the Yamaha MG16XU mixing console first.
3. After the mixer has fully initialized, power on the EKX subwoofers.
4. Finally, power on the EKX loudspeakers.
5. To power off, reverse the sequence: turn off loudspeakers, then subwoofers, then the mixing console.

5.2 Yamaha MG16XU Mixing Console Basics

• Gain Control: Adjust the GAIN knob for each input channel to achieve an optimal input level. The PEAK LED should flash only occasionally.
• EQ Section: Use the HIGH, MID, and LOW knobs to shape the tone of each input.
• Aux Sends: Use AUX 1 and AUX 2 to send signals to external effects processors or monitor mixes.
• Channel Faders: Adjust the volume of individual channels using the faders.
• Master Fader: Control the overall output volume of the mix using the STEREO master fader.
• Effects: The MG16XU features built-in SPX effects. Use the FX RTN fader to control the level of the effects return.

5.3 Electro-Voice EKX Series Loudspeaker Operation

• Input Level: Adjust the INPUT LEVEL knob on the rear panel of each EKX loudspeaker and subwoofer to match the output level from the mixing console. Start with the knob at the 12 o'clock position.
• DSP Presets: The EKX series features integrated DSP with various presets (e.g., Music, Live, Speech). Select the appropriate preset for your application using the rear panel controls.
• Subwoofer Crossover: Ensure the subwoofer's crossover frequency is set appropriately to blend seamlessly with the full-range loudspeakers. Refer to the individual EKX subwoofer manual for detailed DSP settings.

5.4 Microphone Usage

• Placement: Position microphones appropriately for the sound source. For vocals, maintain a consistent distance from the microphone.
• Gain Staging: Adjust the GAIN on the mixer channel for each microphone to prevent clipping (distortion) while ensuring a strong signal.
• Feedback Prevention: Avoid pointing microphones directly at loudspeakers. Use the mixer's EQ to reduce frequencies that cause feedback.

5.5 Bluetooth Connectivity (Alto Professional Receiver)

1. Power on the Alto Professional Bluetooth Receiver.
2. Activate Bluetooth on your audio device (smartphone, tablet, laptop).
3. Search for and select the Alto Professional receiver in your device's Bluetooth settings.
4. Once paired, audio from your device will stream wirelessly to the mixing console. Adjust the channel fader on the mixer for the Bluetooth input.

6. Maintenance

• Cleaning: Use a soft, dry cloth to clean the exterior surfaces of all components. For stubborn dirt, a slightly damp cloth can be used, but ensure no moisture enters the units. Do not use abrasive cleaners or solvents.
• Storage: When not in use, store the equipment in a cool, dry place, away from direct sunlight and extreme temperatures. Use protective covers or cases if transporting or storing for extended periods.
• Cable Care: Regularly inspect all cables for signs of wear, cuts, or damage. Replace damaged cables immediately. Coil cables neatly after use to prevent tangles and damage.
• Ventilation: Periodically check that ventilation grilles on loudspeakers, subwoofers, and the mixer are free from dust and debris. Use a soft brush or compressed air to clear blockages.

7. Troubleshooting

7.1 No Sound Output

• Check Power: Ensure all components (mixer, loudspeakers, subwoofers) are powered on and their power indicators are lit.
• Check Connections: Verify all audio cables are securely connected between the mixer, subwoofers, and loudspeakers.
• Volume Levels: Confirm that the master fader on the mixer is up, individual channel faders are up, and the input level knobs on the loudspeakers/subwoofers are not at minimum.
• Input Source: Ensure the correct input source is selected on the mixer and that the source device (e.g., Bluetooth device) is playing audio.

7.2 Distorted Sound

• Gain Staging: Reduce the GAIN knob on the mixer channel if the PEAK LED is constantly lit. Also, check the input level on the loudspeakers/subwoofers.
• Master Volume: Lower the master fader on the mixer if the overall output is too high.
• Cable Integrity: Inspect audio cables for damage or loose connections.

7.3 Feedback (High-pitched Squeal)

• Microphone Placement: Move microphones further away from loudspeakers. Avoid pointing microphones directly at speakers.
• EQ Adjustment: Use the EQ on the mixer to cut frequencies that are causing feedback. Common feedback frequencies are often in the mid-range.
• Gain Reduction: Lower the gain of the microphone channel or the master volume.

7.4 Bluetooth Connection Issues

• Receiver Power: Ensure the Alto Professional Bluetooth Receiver is powered on.
• Pairing Mode: Put the receiver into pairing mode if it's not automatically discoverable.
• Device Bluetooth: Confirm Bluetooth is enabled on your audio device and it's not connected to another device.
• Distance: Ensure the audio device is within the effective range of the Bluetooth receiver.
