AtlasIED MA40G 3-Input, 40W Mixer Amplifier with Global Power Supply

Optimize small-to-medium commercial paging, background music (BGM) and speech-privacy systems with the AtlasIED MA40G mixer amplifier. This pro amplifier combines a balanced mic/line input (with phantom power and adjustable mute sensitivity) plus two summing line inputs, so integrators can mix live paging, music and local announcements without additional processing. Delivering 40W RMS into 70.7V/100V distributed speaker lines and a frequency response suited for clear voice intelligibility (50 Hz–20 kHz), the MA40G produces reliable audio for retail, education, healthcare and corporate environments. Its global 100–240V power supply reduces logistics complexity for multi-site deployments, while removable level controls and contact-closure mute provide tamper-resistant, professional installations that integrate easily with security, surveillance and monitoring systems. Built for dependable pro audio performance, the AtlasIED MA40G is an efficient choice for installers specifying paging and AV for mixed-use facilities. Add the MA40G to your next security or AV project to streamline paging and BGM — order today or contact us for system design assistance.
