Overview
The PD764 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 PD764 may be used in clusters with other PD family modules or singly as part of a distributed system. PD100 series low-frequency elements may be added to the array to extend bandwidth and pattern control to the lowest octaves.
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 8 in horn loaded cone mid frequency 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.
