The LMA101 100W linkable single-channel zone amplifier is a versatile commercial power amplifier designed for distributed audio systems requiring reliable performance, flexible speaker compatibility, and simple system expansion. Delivering 100 watts of clean output power, the LMA101 functions as either a standalone zone amplifier or an expansion amplifier when paired with AtlasIED DMA Series mixer amplifiers, making it ideal for retail stores, restaurants, hospitality venues, offices, educational facilities, and other commercial audio installations.
Designed for maximum installation flexibility, the LMA101 supports 2Ω, 4Ω, 8Ω, 25V, 70.7V, and 100V loudspeaker systems, allowing seamless integration into both low-impedance and constant-voltage distributed audio applications. Its high-efficiency switch-mode, auto-sensing universal power supply delivers consistent performance across varying AC power conditions, while the advanced output stage provides stable voltage and current for dependable audio reproduction and long-term reliability.
The LMA101 includes a comprehensive set of installer-friendly features that simplify system configuration and maintenance. Balanced line-level inputs, summed RCA inputs, rear-panel detented gain controls, remote level controller compatibility, and GPI connections for priority mute and standby provide flexible integration into commercial sound systems. AtlasIED's exclusive Push Here Diagnostic (PHD) speaker diagnostic system quickly verifies loudspeaker wiring and load integrity with the press of a button, reducing installation time and troubleshooting. Housed in a compact 1RU half-rack chassis with an included rack-mount kit, the LMA101 provides a scalable, space-saving amplification solution for professional commercial audio environments.
