UPA-1C UltraSeries Loudspeaker
Designed for a wide variety of sound reinforcement applications, the compact, arrayable UPA-1C allows controlled coverage of wide areas in theater, club and concert sound reinforcement. The powerful loudspeaker delivers high sound pressure levels with extremely low distortion, for maximum intelligibility and fidelity.
The UPA-1C loudspeaker operates as a system with the M-1A Control Electronics Unit (one per channel). Optimized for the UPA-1C and UM-1C UltraMonitor and pre-aligned at the factory, the M-1A contains frequency response and phase response alignment circuitry, and Meyer Sound's exclusive SpeakerSense driver protection circuitry, incorporating both peak and RMS signal limiting.
UM-1C UltraMonitor Loudspeaker
UltraMonitor delivers the final word on high-powered, critical monitoring.
Specifically designed for touring reinforcement, the highly accurate, rugged
UM-1C biamplified system consists of a proprietary 12-inch low-frequency driver
in a vented enclosure, and a symmetrical pattern 45- degree high-frequency horn
The UM-1C proprietary drivers provide exceptional efficiency and power handling, with ultra-low distortion for high clarity. Very flat frequency response allows control of feedback at high sound levels. The sturdy, multi-ply hardwood enclosure with textured finish withstands road abuse. The unit comes with handles and, optionally, aircraft-style rigging pan fittings.
