Description
The AtlasIED LMA401 is a high-output, single-channel amplifier designed for demanding commercial audio installations that require increased power, scalability, and system reliability. It can be deployed as a standalone amplifier or integrated as a secondary zone, subwoofer amplifier, or expansion channel when linked with an AtlasIED DMA Series mixer amplifier.
Delivering 400 watts of output power, the LMA401 supports 2 Ω, 4 Ω, 8 Ω, and constant-voltage loudspeaker systems, allowing it to drive large distributed systems or high-SPL reinforcement applications with confidence. The global auto-sensing switch-mode power supply and robust output stage ensure stable performance while delivering high voltage and current simultaneously to complex loudspeaker loads.
Designed for efficient installation and commissioning, the LMA401 includes balanced line inputs, summed RCA connections, GPI control ports, and remote level control capability. When connected to a DMA amplifier via the proprietary Link Bus, the LMA401 operates as a gain-matched extension of the system, enabling flexible placement up to 100 meters away. Push Here Diagnostic (PHD) provides fast verification of speaker wiring and load conditions, reducing installation time and ensuring system readiness.
