Meyer Sound UPA-2P Self-Powered Loudspeaker
Meyer Sound UPA-2P Self-Powered Loudspeaker
The Meyer UPA-P Series self-powered loudspeakers (UPA-1P,UPA-2P) are more than powered versions of the Meyer UPA-C Series (UPA-1C, UPA-2C). The UPA-P Series features phase-corrected electronics that produce flat acoustical phase and amplitude responses, resulting in exceptional system impulse response and precise imaging. Despite the inclusion of amplification and control electronics, the UPA-P is the same size as, and only 10 lb.heavier than the UPA-C. Additionally, the UPA-P’s advanced horn designs achieve a consistent polar response and smooth arraying behavior.
Features:
- Exceptional fidelity and extended high- frequency performance
- Surprising power capability in a compact package
- Extraordinarily flat amplitude and phase response for tonal accuracy and precise imaging
- Constant-Q horn affords uniform response throughout the coverage area
- Narrow pattern enables precisely controlled coverage and arrayability and increases efficiency at high frequencies
- Predictable array performance ensures system design flexibility
- Symmetrical horn allows loudspeakers to be oriented horizontally or vertically
