5. Installation

The PRO-HP52 horn waveguide is designed for easy bolt-on installation with compatible 2-inch compression drivers. Ensure you have a suitable compression driver with a 4-bolt mounting pattern.

5.1 Required Tools (Not Included)

Appropriate wrench or socket set for mounting bolts.
Screwdriver (if applicable for driver terminals).

5.2 Installation Steps

Carefully unpack the horn waveguide and inspect for any damage.
Align the mounting holes of the PRO-HP52 horn with the bolt pattern on your compatible 2-inch compression driver.
Insert the provided bolts (or bolts supplied with your compression driver) through the horn's mounting holes and into the compression driver.
Securely fasten the bolts, ensuring a snug fit without overtightening to prevent damage to the plastic.
Once the horn is attached to the driver, proceed with mounting the assembled unit into your desired enclosure or panel.

6. Operating Instructions

The PRO-HP52 horn waveguide functions as an acoustic amplifier and disperser for a connected compression driver. Its operation is dependent on the specifications and proper connection of the compression driver it is paired with.

Ensure the compression driver is correctly wired to your audio system's amplifier according to the driver's specific instructions.
Verify all connections are secure to prevent signal loss or damage.
Start with low volume levels and gradually increase to your desired listening level to avoid overdriving the compression driver.

7. Maintenance and Care

Cleaning: Use a soft, damp cloth to wipe the surface of the horn waveguide. Avoid abrasive cleaners or solvents that could damage the chrome finish.
Inspection: Periodically check the mounting bolts for tightness. Vibrations can sometimes loosen fasteners over time.
Storage: If storing the unit for an extended period, keep it in a cool, dry place away from direct sunlight and extreme temperatures.

8. Troubleshooting

This section addresses common issues that may arise during the use of the PRO-HP52 horn waveguide. Note that most audio performance issues are related to the connected compression driver or the audio system itself.

No Sound:
- Check the wiring connections between the compression driver and the amplifier.
- Verify the compression driver is functioning correctly (refer to its specific manual).
- Ensure the amplifier is powered on and receiving a signal.
Distorted Sound:
- Reduce the volume level to check if the compression driver is being overdriven.
- Inspect the compression driver for any physical damage or diaphragm issues.
- Ensure the horn is securely attached to the driver.
Loose Horn:
- Tighten the mounting bolts connecting the horn to the compression driver. Do not overtighten.
