{"product_id":"atlasied-eqm131","title":"AtlasIED EQM131 1\/3 Octave Graphic Equalizer for PA and Masking","description":"\u003cp\u003eThe AtlasIED EQM131 is purpose-built for AV integrators and system designers who need reliable, cost-effective equalization in sound masking and public address installations. Its ISO-centered, bandwidth-constant Q filter design keeps adjacent filter interaction to a minimum while remaining broad enough to shape correction curves for intelligibility and masking spectrum control — making it a practical tool for tuned installs rather than a compromise product.\u003c\/p\u003e\u003cp\u003eWith rear-panel XLR, balanced TRS, and unbalanced RCA connections, the EQM131 drops into virtually any signal chain without adapters or format converters. Front-panel HPF\/LPF switches, output level control, and a +\/-6 or +\/-12dB operating range give the operator direct control over the EQ's headroom and correction depth without entering a menu. For integrators deploying AtlasIED AA120M mixer amplifier systems with the AA-SMG sound masking module, the EQM131 slots directly into that workflow, shaping the masking spectrum independently of paging and music inputs so summed sources don't corrupt the masking curve.\u003c\/p\u003e\u003cp\u003eAll-metal construction and a low noise floor make this unit suitable for permanent rack installations where reliability and signal integrity matter long-term. The three-year warranty backs it for commercial deployment in education, corporate, and hospitality environments where serviceability expectations are high.\u003c\/p\u003e","brand":"Atlas Sound, L.P. - Mitek","offers":[{"title":"Default Title","offer_id":51438566473912,"sku":"15452","price":429.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/15452_AtlasIED-EQM131-1-3-Octave-Graphic-Equalizer.jpg?v=1767902639","url":"https:\/\/soundpro.com\/products\/atlasied-eqm131","provider":"SoundPro","version":"1.0","type":"link"}
