The Anchor LibertyMP-4601 MPA-4600 is a highly versatile dual-function professional speaker system engineered for mobile public address applications and entertainment. This integrated system is defined by its unique operational flexibility, allowing it to function as a passive speaker when paired with an external amplifier and as a powered monitor when its built-in amplifier module is engaged. This dual capability makes it an invaluable asset for mobile entertainers, rental companies, and venues that require a single audio solution adaptable to a wide variety of event formats, from live music reinforcement to spoken-word announcements at outdoor gatherings.

The system's core is a robust, large-format speaker cabinet housing high-performance transducers. It typically features a heavy-duty woofer and a high-frequency driver coupled with a wide-dispersion horn, designed to deliver clear, articulate sound with substantial output and projection. The integrated MPA-4600 power amplifier module is a key component, providing substantial wattage to drive the speakers when used in active mode. For passive operation, the system includes high-quality internal wiring and heavy-duty speakon connectors, allowing it to be seamlessly integrated into larger, amplifier-driven sound systems. This design ensures consistent audio performance regardless of the chosen operational mode.

Constructed for durability in mobile use, the cabinet is built from rugged, multi-layered plywood with a textured, weather-resistant exterior coating to withstand the physical demands of transport and outdoor environments. The design incorporates ergonomic handles and optional casters for mobility, and it is engineered to be stackable for space-efficient storage and transport. This combination of sonic power, functional duality, and road-ready construction positions the Anchor LibertyMP-4601 MPA-4600 as a comprehensive audio solution for professionals who require a reliable, high-output speaker capable of meeting the unpredictable needs of the mobile sound market, effectively serving as both a main PA cabinet and a self-powered monitor from a single, robust enclosure.
