The UPM-1P is a compact, self-powered loudspeaker designed for professional sound reinforcement where a small, unobtrusive cabinet must still deliver high sound pressure, low distortion, and consistent coverage. Its integrated amplification and signal processing simplify setup and reduce the need for external electronics.

Key Features

• Integrated two-channel amplification and active crossover, providing on-board driver protection and frequency and phase alignment for reliable, coherent output.
• Uniform 100° high-frequency coverage from a 1-inch metal dome tweeter mounted on a constant-directivity horn, for even dispersion across listening areas.
• Dual 5-inch low-frequency drivers with phase-correction, delivering solid mid-bass output while avoiding mid-band comb filtering by rolling off one driver above 320 Hz.
• Superior input stage with a laser-trimmed differential design for improved common-mode rejection, enabling long cable runs with reduced noise when using balanced cable.
• Built-in safety and power handling, including driver voltage limiters and an integral power supply that suppresses high-voltage transients.
• Flexible AC options, the standard unit is switchable between 115 V and 230 V AC. Two PowerCON AC connectors support AC looping. A 100 V AC version is available upon request.

Use Cases

• Small PA and vocal reinforcement, ideal for speech, acoustic performance, or foreground vocals where clarity and low distortion are priorities.
• Fill and delay speaker in larger indoor or outdoor systems, providing consistent coverage without drawing attention to the cabinet.
• Compact full-range setups when paired with an optional subwoofer for extended low-frequency response.

Included with your rental

• One Meyer Sound UPM-1P powered loudspeaker, including the internal amplifiers, active crossover, and protection circuitry.
• Power connectivity, two PowerCON AC connectors on the unit. A standard IEC or country-appropriate power cable is supplied unless otherwise requested.
• Documentation, basic user guide and safety instructions.
• Optional accessories available separately, such as a compatible subwoofer, rigging hardware, or speaker stands. Please request these when booking.

Practical notes

This loudspeaker is supplied in a neutral, rental-ready configuration. For longer cable runs use balanced cable to take advantage of the differential input stage. If you require a 100 V AC model, a subwoofer, or additional mounting hardware, indicate these needs at the time of reservation so we can include compatible items and cabling.
