Jbl Professional Control 24CT Micro Ceiling Speaker

Product Description

The JBL PROFESSIONAL CONTROL 24CT MICRO is a compact in-ceiling loudspeaker with a built-in transformer, designed for commercial and residential distributed audio installations. The integrated transformer makes it compatible with 70-volt and 100-volt constant-voltage speaker systems, which are standard in multi-zone commercial audio environments. This unit is sold individually and is intended for permanent ceiling installation in light commercial, retail, hospitality, or similar settings. Installation is typically performed by a licensed low-voltage or audio-visual contractor familiar with distributed audio system design.

The CONTROL 24CT MICRO fits applications where a small-footprint ceiling speaker is needed without sacrificing transformer-driven system compatibility. Typical install scenarios include background music systems, paging systems, and general voice or music distribution in spaces with suspended or hard-lid ceilings. Its compact form factor makes it well-suited for areas with limited plenum depth or where a low-profile aesthetic is required. Note that this part has been discontinued by the manufacturer and may have limited availability.

Installation Notes

Installation should be performed by a qualified low-voltage technician or licensed audio-visual contractor. Power down and de-energize the amplifier or distribution system before wiring or mounting. Follow applicable local electrical codes and NEC guidelines for low-voltage wiring in plenum or non-plenum ceiling spaces. Verify transformer tap settings match the intended wattage allocation for the zone before finalizing connections.
