The AtlasIED LMA101 is a 100-watt, single-channel Class D commercial power amplifier engineered for reliable, flexible audio performance in small to mid-size installations. Designed to operate as either a standalone zone amplifier or as an expansion amplifier for AtlasIED DMA Series mixer amplifiers, the LMA101 delivers clean, consistent power across a wide range of commercial audio applications.
Supporting low-impedance loads down to 2Ω and distributed audio systems including 25V, 70.7V, and 100V, the LMA101 provides installation versatility for restaurants, retail stores, presentation rooms, and educational facilities.
Its high-efficiency switch-mode global auto-sensing power supply ensures dependable operation even in unstable power environments. The Class D output stage is optimized to deliver both voltage and current simultaneously, maintaining stable loudspeaker performance under demanding conditions.
For integrators, the LMA101 simplifies installation and commissioning with:
-
Balanced line input and summed RCA inputs
-
Rear-panel detented gain control
-
Remote level controller compatibility (DMA-V, DMA-VS)
-
GPI ports for standby and priority mute
-
Push Here Diagnostic (PHD) speaker verification system
The compact 1RU half-rack chassis includes a rack kit and features convection cooling for silent operation — making it ideal for noise-sensitive environments.
