7. AC LINK: Powercon connector for output connection to another speaker.
8. AC IN: Powercon connector for connection to AC 120V power source.

4. Setup Instructions

4.1. Getting Started Guide

1. Connect Power: Connect the power cable to the loudspeaker. Ensure the socket is properly grounded to minimize the risk of potential failures due to voltage returns.
2. Insert Signal Cable: Insert the signal cable into the input using an XLR or TRS Jack.
3. Turn Down Gain: Turn the Volume knob all the way down (counter-clockwise).
4. Turn On: Flip the power switch to the 'ON' position.
5. Increase Gain: Gradually increase the Volume knob clockwise to the desired level.

4.2. Connections

Current Link: PRORECK provides power center solutions for distributing necessary power to linear systems. Consult your distributor for options.

Signal Link: For signal linking, PRORECK offers signal cables to cascade the signal between multiple speakers. Connect a long signal cable from your source (e.g., mixer or processor) to the first speaker's input, then use the 'Output' XLR to link to the next speaker's input, and so on.

4.3. Rigging (Suspending)

PRORECK provides a hanging adapter for suspending the equipment. Insert appropriate shackles into the designated rigging points (boomer holes) along with the load sling to connect it to your lifting system. Ensure all rigging is performed by qualified personnel following safety guidelines.

4.4. Stacking

If placing the equipment on a surface or subwoofer, the bumper can be used in this position by simply inverting the equipment to provide a stable base.

4.5. DSP Presets

In linear systems, adding more cabinets to the array causes a low-frequency summation effect, changing the frequency response. The DSP presets compensate for this to optimize sound.

• Preset 1: Front Field (Indicator LED: Front Field)
  • Use for arrangements of up to 3 boxes.
  • Ideal for stacking on the floor or on a subwoofer.
  • Provides the flattest frequency response, suitable for using one box per side.
• Preset 2: 4 to 8 Boxes (Indicator LED: 4-8)
  • Use for arrangements of 4 to 8 boxes, whether flown or stacked on a subwoofer.
  • Compensates for low-mid summation, maintaining a flat frequency response suitable for any musical genre.
• Preset 3: 9 to 12 Boxes (Indicator LED: 9-12)
  • Use for arrangements of 9 to 12 hung boxes (the maximum supported by the system).
  • Further attenuates low-mid frequencies to ensure better distribution and frequency response throughout the entire volume.

5. Operation

Once the speaker system is set up and connected as described in Section 4, follow these steps for operation:

• Power On: Ensure all connections are secure, then turn on the speaker using the power switch on the back panel. The 'Power' LED should illuminate.
• Select DSP Preset: Based on your array configuration (number of speakers and setup), select the appropriate DSP preset using the selector button on the back panel. Refer to Section 4.5 for details on each preset.
• Adjust Volume: Start with the 'Volume' knob turned down. Play your audio source and gradually increase the 'Volume' knob on the speaker until the desired sound level is achieved. Monitor the 'Clip' LED; if it flashes frequently, reduce the volume from your source or the speaker to prevent distortion and potential damage.
• Monitor Signal: The 'Signal' LED indicates that an audio signal is present at the input.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your PRORECK speaker system.

• Cleaning: Keep the unit clean and free from dust. Use a soft, dry cloth to wipe down the exterior. Do not use abrasive cleaners, solvents, or harsh chemicals.
• Environmental Conditions: Avoid exposing the speaker to extreme temperatures, high humidity, or direct sunlight for extended periods.
• Cable Inspection: Regularly inspect all power and signal cables for any signs of wear, cuts, or damage. Replace damaged cables immediately.
• Ventilation: Ensure that the speaker's vents (if any) are not obstructed to allow for proper airflow and prevent overheating.
• Storage: When not in use for extended periods, store the speaker in a dry, cool place, ideally in its original packaging or a protective case.

7. Troubleshooting

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

8. User Tips

• Always ensure proper grounding for all electrical connections to prevent hum and potential electrical hazards.
• Experiment with the different DSP presets (Front Field, 4-8, 9-12) to find the optimal sound profile for your specific venue, audience size, and number of speakers in your array.
• When linking multiple speakers, use high-quality XLR cables for signal integrity and Powercon cables for secure power distribution.
