5.2. Presets

In linear systems, adding more cabinets to the array causes a low-frequency summation effect, which changes the frequency response by increasing mid and low frequencies in larger arrays. The PR-208AP offers three preset modes to compensate for this and optimize sound for different array sizes.

Figure 5.2: Preset selector on the rear panel.

5.2.1. Preset 1: Front Field (Up to 3 Boxes)

This preset is designed for use with up to 3 speaker boxes. It is ideal for stacking on the floor or on a subwoofer, or for using one box per side. This preset provides the flattest frequency response.

Figure 5.2.1: Front Field preset setup (up to 3 boxes).

5.2.2. Preset 2: 4 to 8 Boxes

This preset is designed for use with 4 to 8 speaker boxes, whether flown or stacked on a subwoofer. It compensates for low-mid summation, ensuring a flat frequency response suitable for any musical genre.

Figure 5.2.2: 4 to 8 Boxes preset setup.

5.2.3. Preset 3: 9 to 12 Boxes

This preset is for use with 9 to 12 hung boxes, which is the maximum number of boxes the system supports. This preset further attenuates the low-mid frequencies to ensure better distribution and frequency response throughout the entire volume.

5.3. Connections

5.3.1. Current Link (Power)

PRORECK provides a power center solution capable of distributing the necessary power for optimal performance of linear systems. Consult your nearest distributor for more information on power distribution options.

Figure 5.3.1: Power linking diagram.

5.3.2. Signal Link

For signal linking, PRORECK offers signal links in its catalog that allow you to cascade the signal between boxes. You only need a long signal cable from a source, such as a mixer or processor, to the first speaker, and then link subsequent speakers.

Figure 5.3.2: Signal linking diagram.

6. System Configuration

6.1. Rigging

PRORECK provides a hanging adapter for suspending the equipment. Insert the shackles into the boomer holes along with the load sling to connect it to your lifting system.

Figure 6.1: Rigging frame and shackles.

6.2. Stacking

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

8. Maintenance

To ensure the longevity and optimal performance of your PRORECK PR-208AP speakers, follow these maintenance guidelines:

• Cleaning: Regularly wipe down the exterior with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the finish.
• Ventilation: Ensure that all ventilation openings are clear of dust and debris to prevent overheating.
• Cable Inspection: Periodically check all power and signal cables for any signs of wear, cuts, or damage. Replace damaged cables immediately.
• Storage: When not in use, store the speakers in a dry, cool environment, away from direct sunlight and extreme temperatures. Use protective covers if available.
• Professional Servicing: Do not attempt to service the unit yourself. Refer all servicing to qualified PRORECK service personnel.

9. Troubleshooting

If you encounter issues with your PRORECK PR-208AP speakers, consider the following common troubleshooting steps:

• No Power:
  • Check if the power cable is securely connected to both the speaker and a working power outlet.
  • Verify that the power switch on the rear panel is in the 'ON' position.
  • Ensure the power outlet is supplying power (test with another device).
• No Sound:
  • Confirm that the signal cable is correctly connected to both the input source and the speaker's input jack.
  • Check the volume/gain knob on the speaker and the output level of your audio source (mixer, processor).
  • Ensure the 'Signal' LED on the rear panel is illuminated, indicating an incoming audio signal.
  • If using multiple speakers, check the signal link connections between them.
• Distorted Sound / Clipping:
  • If the 'Clip' LED is frequently illuminated, reduce the input gain on the speaker or the output level from your audio source.
  • Ensure the correct preset is selected for your array size (Front Field, 4-8, or 9-12 boxes).
  • Check for damaged cables or faulty connections.
• Intermittent Sound:
  • Inspect all cables for loose connections or damage.
  • Ensure power connections are stable and not intermittent.

If these steps do not resolve the issue, please contact PRORECK customer support for further assistance.

10. User Tips

• Optimal Placement: Experiment with speaker placement and angle to achieve the best sound coverage for your specific venue.
• Preset Selection: Always select the appropriate preset (Front Field, 4-8, or 9-12 boxes) based on the number of speakers in your array for balanced sound.
• Gain Staging: Set the gain levels carefully to avoid clipping and ensure a clean audio signal. Start with the gain low and gradually increase it.
• Cable Management: Use high-quality cables and manage them neatly to prevent tripping hazards and signal interference.
