100W Linkable Single Channel Zone Amplifier

LMA101

  • 25/70/100V Capable
  • 2/4/8 Ohm Capable
    DESCRIPTION

    The AtlasIED LMA101 is a 100W single-channel, multi-impedance power amplifier designed to serve either as a standalone zone amplifier or as an expansion amplifier when paired with an AtlasIED DMA Series mixer amplifier. Its straightforward architecture and integrator-friendly controls make it well suited for small commercial spaces, auxiliary zones, or applications requiring dedicated amplification without added system complexity.

    Supporting low-impedance loads down to 2 Ω as well as 25 V, 70.7 V, and 100 V distributed audio systems, the LMA101 offers flexibility across a wide range of installation scenarios. A high-efficiency, switch-mode global auto-sensing power supply ensures consistent output and reliability even in unstable power environments, while the output stage is engineered to deliver clean voltage and current simultaneously for dependable loudspeaker performance.

    For streamlined installation and commissioning, the LMA101 includes balanced line inputs, summed RCA connections, rear-panel detented gain control, remote level control capability, and GPI ports for standby or priority override. The built-in Push Here Diagnostic (PHD) function verifies speaker wiring and load conditions with a single button press, helping integrators confirm system integrity before project handoff.
