2.4 Configuració del crossover

A passive or active crossover is essential to protect the compression driver from low frequencies that can cause damage. Refer to your system's amplifier or crossover manual for specific settings.

• Set the high-pass filter (HPF) for the driver channel to at least 1.5 kHz (1500 Hz) with a slope of 12dB/octave or higher.
• Adjust the crossover point based on your specific system and listening preferences, ensuring the driver is not subjected to frequencies below its recommended range.

3. Instruccions de funcionament

3.1 Engegada inicial

After installation, perform a low-volume test to confirm proper functionality.

1. Turn on your audio system with the volume set to minimum.
2. Gradually increase the volume to a low listening level.
3. Listen for clear, undistorted sound from the PRO-DR2 driver.

3.2 Gain and Level Adjustment

Guany adequat staging is crucial to prevent distortion and maximize sound quality.

• Estableix el amplifier gain for the driver channel according to the amplifier's instructions, typically by playing a test tone and adjusting until the clipping indicator just begins to flash, then backing off slightly.
• Avoid setting the gain too high, as this can lead to clipping and damage to the driver.

3.3 Avoiding Distortion

Distortion is a primary cause of driver failure. Always operate your system within its clean power limits.

• If you hear any harsh, crackling, or fuzzy sounds, immediately reduce the volume.
• Assegureu-vos el vostre ampEl salvador no s'està retallant.
• Verify that your crossover settings are correct and protecting the driver from low frequencies.

4. Manteniment
