Jbl Professional MTC-CBT-70T 70V Transformer Pair

Product Description

The JBL PROFESSIONAL MTC-CBT-70T is a 70-volt transformer option designed for use with compatible CBT series column array speakers. It enables connection of CBT series loudspeakers to 70V distributed audio systems, which are the standard wiring topology in commercial and institutional sound installations. The transformer integrates into the speaker assembly to allow compliant operation on 70V lines without requiring a separate external device. Installation is handled by licensed audio systems contractors or professional AV integrators working on distributed sound projects.

This accessory is applicable in commercial environments where 70V distributed audio is required, including houses of worship, schools, retail spaces, transportation facilities, and similar venues. It is sold as a pair, making it suited for stereo or dual-coverage installations. The MTC-CBT-70T is intended for use with JBL CBT series column array speakers and is not a standalone loudspeaker component.
