JBL MTC-TB6-8 Tile Bridge for Control 200 and Control 300 Series

JBL Professional MTC-TB6-8 - Tile Bridge for Control 200 and Control 300 Series

The JBL Professional MTC-TB6-8 (official designation MTC-TB6/8) is a modular drop ceiling tile bridge designed to distribute the load of Control Series in-ceiling speakers and ensure a solid and quiet installation. Its 18-gauge steel construction with an epoxy powder-coat finish offers high rigidity and corrosion resistance. The over-the-grid design reduces vibration transmission to the ceiling framing , minimizing unwanted hum and buzz in commercial audio installations.

The backplane features a 310mm circular cutout that fits snugly into the Control 328C/CT and Control 227C/CT models when used with their matching backboxes ( MTC-300BB8 and MTC-200BB6 ). It fits into 600mm and 610mm ceiling grids , covering the 60x60cm and 24x24in standards common in offices, retail, hospitality and education spaces. Its overall dimensions are 646mm (length) × 413mm (width) and the net weight is 2.1kg , facilitating comfortable handling on site without sacrificing robustness.
