Setup and Installation

Proper installation is crucial for optimal performance and safety. It is recommended that installation be performed by a qualified professional.

Mounting

Ensure the mounting surface is sturdy enough to support the weight of the compression driver (7 pounds).
Refer to the product dimensions (6"D x 6"W x 7.75"H) and throat diameter (2") to prepare the mounting hole.
Secure the compression driver using appropriate fasteners through the mounting holes on the horn.

Wiring

Connect the positive (+) terminal of the compression driver to the positive output of your amplifier.
Connect the negative (-) terminal of the compression driver to the negative output of your amplifier.
Ensure all connections are secure and properly insulated to prevent short circuits.
It is recommended to use a high-pass filter (HPF) to protect the driver from low frequencies. A crossover that cuts frequencies below 800Hz is ideal for this unit.

Operating Instructions

The DS18 PRO-DKH1 is designed to reproduce high frequencies with clarity and power. Follow these guidelines for optimal operation:

Ensure your amplifier is properly matched to the 8 Ohm impedance of the driver.
Avoid exceeding the recommended RMS power of 600W to prevent damage.
Use a high-pass filter (HPF) to prevent low-frequency signals from reaching the driver, which can cause distortion and damage.
Gradually increase volume levels to prevent sudden peaks that could harm the driver or your hearing.

Maintenance

Regular maintenance helps ensure the longevity and performance of your compression driver.

Cleaning: Use a soft, dry cloth to wipe down the horn and driver body. Avoid using harsh chemicals or abrasive materials.
Inspection: Periodically check all wiring connections for tightness and signs of wear or corrosion.
Environment: Keep the driver in a dry environment, away from direct sunlight and extreme temperatures.

Troubleshooting

If you experience issues with your DS18 PRO-DKH1, refer to the following common problems and solutions:

Problem	Possible Cause	Solution
No Sound	Loose wiring, incorrect connections, amplifier off, damaged voice coil.	Check all wiring, ensure correct polarity, verify amplifier power, inspect voice coil for damage.
Distorted Sound	Overpowering, improper crossover settings, damaged diaphragm.	Reduce amplifier gain, verify HPF settings, inspect diaphragm for tears or creases.
Low Output	Incorrect impedance matching, low amplifier power, phase issues.	Ensure amplifier matches 8 Ohm impedance, check amplifier output, verify speaker phase.

If problems persist, contact DS18 customer support or a qualified audio technician.
