• Inputs: The PS18S features combo XLR/1/4-inch inputs. Connect your audio source (e.g., mixer, PA system) to these inputs using appropriate cables.
• Outputs: XLR outputs are provided for linking to additional subwoofers or full-range loudspeakers. These outputs can be configured as "through" connections or with a built-in crossover.
• Power: Connect the supplied power cord to the AC inlet on the rear panel and then to a suitable power outlet.

Operating Your PS18S Subwoofer

Powering On/Off:

Locate the power switch on the rear panel. Flip the switch to the 'ON' position to power on the subwoofer. Ensure all connections are secure before powering on.

Adjusting Volume:

Use the 'Level' control knob on the rear panel to adjust the output volume of the subwoofer. Start with a low volume and gradually increase it to your desired level.

Crossover and DSP Settings:

The PS18S features a built-in digital signal processor (DSP) with a crossover. This allows for precise tuning of the subwoofer's frequency response and seamless integration with other loudspeakers, particularly other Yorkville ELX series speakers. Refer to the on-screen menu (if applicable) or the detailed DSP section of the full manual for advanced settings. You can also manually adjust settings as needed.

Indicator Lights:

• Power: Indicates the unit is receiving power.
• Signal: Illuminates when an audio signal is detected.
• Clip: Illuminates when the input signal is too high, indicating potential distortion. Reduce the input level to prevent clipping.

Care and Maintenance

• Ventilation: Ensure that the ventilation grilles on the rear panel remain clear of dust and debris to prevent overheating.
• Storage: When not in use for extended periods, store the subwoofer in a cool, dry place, away from direct sunlight and extreme temperatures.
• Handling: Always use the integrated metal handles when moving the subwoofer to ensure safe transport and prevent damage.

Troubleshooting Guide

If you encounter issues with your PS18S subwoofer, refer to the following common troubleshooting steps:

1. No Power:
   • Check if the power cord is securely connected to both the subwoofer and a working power outlet.
   • Verify that the power switch on the rear panel is in the 'ON' position.
   • Test the power outlet with another device to ensure it is functional.
2. No Sound:
   • Ensure the audio input cables are securely connected to both the source and the subwoofer's input jacks.
   • Check the 'Level' control knob on the subwoofer; ensure it is not set to minimum.
   • Verify that the audio source (e.g., mixer) is sending a signal and its output level is appropriate.
   • If using the crossover, ensure it is configured correctly and not filtering out all frequencies.
3. Distorted Sound / Clipping:
   • If the 'Clip' indicator light is illuminated, the input signal is too strong. Reduce the output level from your audio source or the 'Level' control on the subwoofer.
   • Ensure all cables are in good condition and properly connected. Faulty cables can cause distortion.
4. Overheating:
   • Check that the subwoofer's ventilation openings are not obstructed.
   • Ensure the subwoofer is operating within its specified temperature range and not in direct sunlight or an enclosed space.

If these steps do not resolve the issue, please contact Yorkville customer support or a qualified service technician.
