Meyer Sound UPQ-D3 Loudspeaker – Remote Monitoring System – Weather Protection – 3-Pin XLR
Meyer Sound UPQ-D3 Large Point-Source Loudspeaker with, Remote Monitoring System, Weather Protection, and 3-Pin XLR
The UPQ-D3 offers an extremely consistent polar response and a gentle coverage rolloff that extends uniformly out to its ‑10 dB points of 100° by 100°. The horn’s smooth and consistent performance is the result of meticulous research in Meyer Sound’s anechoic chamber, and it exhibits a remarkably consistent beamwidth in both the horizontal and vertical planes. The UPQ‑D3 horn also delivers uniform attenuation for all frequencies outside the specified beamwidth.
Features:
- Wide horizontal pattern covers broad listening areas and focused vertical pattern allows precise coverage
- Highly energy efficient amplifier with sophisticated digital signal processing that provides extraordinarily flat amplitude and phase response for tonal accuracy and precise imaging
- Integral stand mount and QuickFly mounting options facilitate rigging
- Constant-Q horn affords uniform response throughout coverage area
- Exceptional size to power ratio provides application flexibility
- Consistent and predictable performance ensures accurate system design
