Fulcrum Acoustic Driveflex

Fulcrum Acoustic Driveflex amplifiers are compact yet powerful, with the performance required to support Fulcrum’s advanced DSP while remaining efficient and easy to deploy. With amplifier control built into Fulcrum One software, Driveflex simplifies design, setup, and monitoring to ensure that every Fulcrum system performs at its highest level.

Core Features

• Compact, lightweight, 1RU rack-mount design

• Flexible channel routing and power sharing across outputs

• Integrated DSP with EQ, crossovers, limiters, and delay

• Embedded TQ Processing for accurate time-domain response and consistent performance across all Fulcrum Acoustic loudspeakers

• Network-ready with Dante/AES67 and remote monitoring

• Comprehensive protection circuitry and energy-efficient operation

Unified Workflow with Fulcrum One

• Amplifiers are uniquely recognised in Fulcrum One software for seamless setup and tuning

• Automatically loads TQ presets and loudspeaker limiters for every Fulcrum product

• Centralised monitoring and control of all amplifiers from anywhere on the network
