About the JBL MTC-SBT300 300W 70V/100V Transformer for Control SB2210

The JBL MTC-SBT300 is a dedicated external multi-tap transformer designed to provide compatibility with 70.7V and 100V constant-voltage amplifier systems for the JBL Control SB2210 compact subwoofer. This accessory transforms the subwoofer from a standard low-impedance (8-ohm) device into a component that can be seamlessly integrated into commercial distributed audio systems, which commonly use constant-voltage topology to drive multiple speakers over long cable runs with minimal power loss. The transformer allows installers to select the appropriate power tap to match the subwoofer's required input power within the system, ensuring optimal performance and protecting the subwoofer from under-powering or overdriving.

The transformer is engineered to handle the specific power requirements and frequency response of the Control SB2210 subwoofer, ensuring that low-frequency performance is maintained with high fidelity. It typically features multiple power tap settings (e.g., 300W, 150W, 75W, etc.), allowing for precise matching to the amplifier's output and the acoustic demands of the installation zone. By using this external transformer, the subwoofer can draw the correct amount of power from a high-voltage line, enabling it to deliver its full bass output in systems where the main amplifier is located far from the speaker location. This is essential for maintaining system headroom and achieving balanced, full-range sound in background music or paging systems that include low-frequency reinforcement.

Installation involves connecting the transformer between the amplifier's constant-voltage output and the subwoofer's input terminals. The unit is built into a compact, durable housing suitable for installation in equipment racks, enclosures, or near the subwoofer itself. As a genuine JBL accessory, the MTC-SBT300 is designed and tested to work flawlessly with the Control SB2210, providing system designers with a reliable and code-compliant method to incorporate powerful, extended bass into commercial audio installations without compromising the efficiency or scalability of the constant-voltage architecture.
