JBL Professional MTC-CBT-70T-WH Bolt-On Transformer Module for CBT 70 Models, White

Convert JBL Professional CBT 70J/JE arrays into true distributed-line speakers quickly and reliably with the MTC-CBT-70T bolt-on transformer module. Designed for integrators and systems engineers, this transformer module provides flexible power taps (120W, 60W, 30W for 70V/100V and 15W for 70V) so you can optimize coverage and SPL across large zones without additional amplifiers. The IP55-rated enclosure and watertight gland nuts ensure long-term performance in outdoor, perimeter, and parking-area applications—ideal for security, surveillance, and public-address deployments. Mounting is simple: the module bolts directly to the back of CBT 70J-1 or CBT 70JE-1 cabinets and extends only 86 mm, keeping installations compact. Internal screw-terminal connections and UL1876 registration simplify code-compliant installations while reducing onsite labor. Whether you’re upgrading a campus paging system, expanding CCTV audio monitoring, or specifying speakers for a retail or transit environment, the MTC-CBT-70T gives you the power flexibility and environmental protection you need. Add this JBL Professional transformer module to your next distributed audio design for dependable amplification and easier system commissioning.
