Jbl Professional MTC-CBT-70T-WH 70V 100V Transformer

Product Description

The JBL PROFESSIONAL MTC-CBT-70T-WH is a 70V/100V transformer accessory designed for use with JBL CBT series column array speakers. This add-on transformer integrates with compatible CBT speaker enclosures to enable connection to 70-volt and 100-volt distributed audio systems, which are the standard signal distribution architecture in commercial and installed sound applications. The transformer handles the voltage-matching function that allows the speaker to operate on a constant-voltage line without requiring a separate external transformer box. Installation is typically performed by a licensed audio systems integrator or commercial electrician familiar with distributed audio infrastructure.

This transformer accessory is intended for commercial installed sound environments including houses of worship, schools, retail spaces, transportation facilities, and other venues where 70V or 100V distributed speaker lines are used. It mounts directly to the associated CBT column speaker, keeping the installation clean and self-contained. The MTC-CBT-70T-WH is finished in white to match white-finish CBT speaker enclosures.

Installation Notes

Follow NEC Article 640 guidelines for audio system wiring in commercial installations. Do not exceed the transformer tap wattage ratings when setting system levels.
