About the Meyer Sound UM-1P / Meyer Sound UM-100P
The Meyer Sound UM-1P and UM-100P are ultra monitors built for high-powered, critical stage monitoring. The UM-1P uses a symmetrical, constant-Q horn for precise coverage with minimal interaction between adjacent units, while the UM-100P features a wide-coverage constant-Q horn that provides maximum freedom of movement for performers. Both models deliver flat frequency and phase response for high gain before feedback, high peak power for excellent transient response, and a low-profile cabinet that preserves sight lines. Built-in precision electronics remove the need for external crossovers or amplifiers. Typical applications include vocal monitoring, keyboard and instrument monitoring, sidefill, and drum fill use in combination with a compatible subwoofer.
Meyer Sound UM-1P / Meyer Sound UM-100P — buyer FAQs
What is the difference between the Meyer Sound UM-1P and the UM-100P?
The UM-1P uses a symmetrical, constant-Q horn designed for precise coverage with minimal interaction between adjacent units, making it suited to situations where controlled dispersion matters. The UM-100P uses a wide-coverage constant-Q horn that gives performers maximum freedom of movement on stage. Both models share the same built-in precision electronics, flat frequency and phase response, and low-profile cabinet design.
What applications are the UM-1P and UM-100P typically used for?
Both monitors are used for vocal stage monitoring, keyboard and instrument monitoring, and sidefill duties. They can also serve as drum fills when combined with a compatible subwoofer. The UM-1P suits positions where precise, narrow coverage is needed, while the UM-100P is preferred where performers move across a wider area.
Who makes the UM-1P and UM-100P, and where do these monitors sit in their range?
Meyer Sound Laboratories is an American professional audio company founded in 1979 by John and Helen Meyer, based in Berkeley, California. The company is known for self-powered loudspeakers, line arrays and subwoofers used across sound reinforcement and fixed installation. The UM-1P and UM-100P sit within its stage monitor line as high-powered, self-powered ultra monitors intended for critical monitoring environments.
Do the UM-1P and UM-100P require external amplifiers or crossovers?
Neither model requires external amplifiers or crossovers. Both units house built-in precision electronics that handle amplification and signal processing internally. This self-contained design simplifies system setup and reduces the amount of additional equipment needed at the stage position.
What should I check when buying a used Meyer Sound UM-1P or UM-100P?
Confirm which variant you are buying, as the UM-1P and UM-100P have different horn coverage patterns suited to different monitoring positions. Check that the built-in electronics are fully functional, since these replace external amplifiers and crossovers. Every listing on this page carries a 21-day warranty covering major functional faults; full details are in the buying guide at 10kused.com/used-av-equipment-guide/.
