AtlasIED MA40G 3-Input Mixer Amplifier With Global Power Supply

The AtlasIED MA40G is built for commercial integrators deploying distributed paging, background music, or small-to-medium sound masking systems where reliability and clean installation are non-negotiable. Its three-input architecture — one balanced mic/line with phantom power and two unbalanced summing line-level inputs — covers the input combinations most often encountered in retail, hospitality, and corporate environments without requiring an external mixer.

Where the MA40G earns its place over generic rack amplifiers is in the details that matter during commissioning and long-term ownership. Removable level controls with a security cover allow integrators to set and lock levels after tuning, eliminating post-install tampering. Contact closure mute terminals support third-party paging triggers and life-safety integration without additional hardware. The variable VOX mute sensitivity on Input 1 provides hands-free mic activation tuned to the room.

The global 100VAC–240VAC power supply makes the MA40G a practical choice for international installations or multi-region projects without sourcing alternate power transformers. Its 1RU half-rack footprint keeps rack space and wiring overhead minimal, a meaningful advantage when building compact equipment closets in small commercial venues or multi-tenant spaces.
