Meyer Sound UM-1P Powered Wedged Stage Monitor

Meyer Sound UM-1P Powered Wedged Stage Monitor

The UM-1P and the UM-100P self-powered stage monitors are designed for high-level, full-bandwidth monitoring, cleanly reproducing stage mixes that include vocals and musical instruments. These units provide efficient response down to 60 Hz. The compact enclosure houses a 12-inch cone driver and a 3-inch-diaphragm compression driver. The combination of high-performance drivers and perfectly matched drive electronics yields flat amplitude and phase response plus near-perfect impulse response over the full audio bandwidth — with benefits including lower susceptibility to feedback. Maximum SPL is 133 dB at one meter, with exceptionally low distortion.

Features:

• Flat frequency and phase response afford high levels of gain before feedback
• The UM-1P offers a symmetrical, constant-Q horn for precise coverage with minimal interaction between adjacent units
• The UM-100P offers a wide-coverage constant-Q horn, providing maximum freedom of movement for performers
• High peak power ensures excellent transient response
• Low-profile cabinet preserves sight lines
• Built-in precision electronics eliminate the need for external crossovers and amplifiers
