{"product_id":"q-sys-nl-c4-wh","title":"Q-SYS NL-C4 Network PoE Ceiling Loudspeaker | White","description":"\u003cp\u003eThe Q-SYS NL-C4 is built for AV integrators and system designers who need a clean, low-infrastructure audio solution in commercial and institutional spaces. By running power, data, and control over a single RJ45 connection via PoE or PoE+, it eliminates dedicated amplifier racks and reduces overall hardware cost. The four-inch full-range driver covers 100 Hz to 20 kHz with a 120-degree dispersion pattern, making it appropriate for corporate meeting rooms, classrooms, hospitality environments, and house-of-worship installations where consistent speech intelligibility and music reproduction are both required.\u003c\/p\u003e\u003cp\u003eAs a native Q-SYS product, the NL-C4 integrates directly into Q-SYS Designer Software without third-party drivers or workarounds. Intrinsic Correction loudspeaker voicings are embedded in the platform, simplifying EQ and tuning workflows that would otherwise require external processing. Remote monitoring and management through Q-SYS Reflect gives facility teams and integrators visibility into device status without on-site access. The NL Series tonal consistency across form factors means mixed deployments of ceiling, surface, and pendant speakers maintain a coherent sound profile throughout a facility.\u003c\/p\u003e\u003cp\u003eThe ABS baffle and powder-coated steel construction carries an IP34 ingress protection rating, suitable for spaces with moderate dust and water exposure. UL 2043 plenum rating satisfies above-ceiling installation code requirements in commercial buildings. Included mounting hardware, tile rails, C-rings, and a cut-out template reduce installation time, while optional accessories such as the NL-C179 bezel-less collar and AD-MR4 mud ring address finish and pre-install requirements for specific ceiling types.\u003c\/p\u003e","brand":"QSC, LLC","offers":[{"title":"Default Title","offer_id":52181714829496,"sku":"132960","price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0871\/7382\/4696\/files\/0003_132960_Q-SYS-NL-C4-network-loudspeaker-network-ceiling-mount-loudspeaker.jpg?v=1772650999","url":"https:\/\/soundpro.com\/products\/q-sys-nl-c4-wh","provider":"SoundPro","version":"1.0","type":"link"}
