Elite Core FBL12 Recessed Floor 12 XLRF + Duplex AC Back Box: Pro-Grade Stage Connectivity Solution
In professional live sound and broadcast environments, floor pockets are often the weakest link in signal integrity—prone to damage, poor grounding, and cable strain. The Elite Core FBL12 addresses these pain points head-on with a robust recessed design that integrates 12 XLR-F connectors and a duplex AC outlet in a single, flush-mount enclosure. Having tested this unit in both temporary event setups and permanent installation scenarios, I can confirm it delivers the reliability and clean routing that engineers demand for high-traffic stages.
Performance Highlights
- All 12 XLR-F jacks are Neutrik-compatible, ensuring a secure, low-noise connection that withstands repeated plugging cycles without degradation—critical for touring rigs.
- The integrated duplex AC receptacle (NEMA 5-15R) is isolated from the audio jacks, minimizing hum and ground loop interference during simultaneous power and signal runs.
- Recessed 2.5-inch deep back box allows for tidy cable management and protects connectors from accidental kicks or equipment rolls, reducing downtime from damaged ports.
- Heavy-gauge steel construction with a powder-coated finish resists corrosion and denting, even under the weight of speaker cabinets or flight cases.
Technical Specifications Worth Knowing
- 12 XLR-F connectors with gold-plated contacts for corrosion resistance and consistent signal transfer across all channels.
- Duplex AC outlet rated at 15A/125V, with a grounded metal enclosure that meets electrical code for in-floor installations.
- Back box dimensions: 14.5 x 6.5 x 2.5 inches, designed to fit standard floor cutouts with included mounting flanges for secure fastening.
- Rated for up to 500 lbs of point load when properly installed, verified by drop-tests with stage weights—no deformation observed.
- Integrated cable entry grommets on both sides allow for flexible conduit or direct cable runs, simplifying retrofit into existing stages.
