JBL PD764i

Very High Output Mid-High Loudspeaker System

The PD764i Precision Directivity™ loudspeaker provides high-impact sound reinforcement at throw distances that are beyond the reach of single-driver designs. A single module produces greater than 104 dB SPL (continuous) at distances of 50 m (165 ft). The PD764i may be used in clusters with other PD family modules or singly as part of a distributed system.

FEATURES

• 60° by 40° Coverage Pattern–symmetrical frontal dimensions allow horizontal or vertical orientation within an array.
• IFS™ Interference Free Summation dual HF driver module eliminates destructive interference and increases output by 6 dB.
• Dual 2432H compression drivers with 3” diaphragms
• Dual CMCD-82H 8” horn loaded cone mid-range drivers provide 6 dB greater output than traditional designs.
• Pattern control maintained to below 400 Hz.
• Co-axial mid / high-frequency module layout improves mid frequency arrayability and minimizes size.
• Integrated rigging system simplifies array design and construction.
