JBL Cinema MA4-D DSi 2.0 Series MA4-D 700W 4-Channel Amplifier

Professional Power Amplifier For Cinema Applications
The Crown DSi-Series MA4-D is a 4-channel professional cinema power amplifier engineered to deliver powerful, accurate, and reliable performance in theater environments. Designed specifically for JBL cinema loudspeakers, it combines high output with advanced onboard processing to ensure every seat in the auditorium experiences clear, detailed sound. With Dante/AES67 audio networking and built-in presets, the MA4-D offers seamless integration into modern immersive cinema systems.

Advanced DSP Processing For Optimal Performance
At the core of the MA4-D is a 96 kHz/32-bit floating-point DSP engine that eliminates the need for external processors. This powerful internal processing includes FIR filtering, 8-band parametric EQ, crossover management, delay adjustments, and LevelMAX limiting. By providing these functions within the amplifier, the MA4-D ensures precise system tuning and enhanced loudspeaker protection, reducing complexity and installation costs.

High Output Power With Flexible Operation
The MA4-D delivers 700 watts per channel with bridgeable outputs, allowing it to meet the demanding requirements of large-scale surround systems. Its high-power 2-ohm mode supports up to four surround speakers per channel, making it ideal for immersive audio formats like Dolby Atmos. This versatility enables integrators to maximize efficiency and reduce the number of amplifiers required for complex cinema installations.

Seamless Integration With Cinema Systems
Designed for modern theaters, the MA4-D includes JBL cinema speaker tuning presets that optimize system performance while protecting components. The amplifier communicates directly with third-party Theater Management Systems (TMS) and Cinema Control (NOC) setups via SNMP, providing remote monitoring and fault management. A HiQnet port connects to HARMAN’s Audio Architect software for full configuration, control, and monitoring capabilities across the network.

Simplified Setup And Easy Control
The intuitive front-panel LCD and encoder make configuration straightforward, allowing operators to adjust settings, mute channels, and recall presets with ease. Rear-panel connectivity includes Euroblock analog inputs, terminal strip speaker outputs, and RJ45 network ports. An additional GPIO/AUX port provides external access for monitoring amplifier health and controlling power or presets, ensuring a flexible workflow for technicians and theater staff.

Reliable Performance With DriveCore Technology
Crown’s patented DriveCore technology condenses hundreds of components into a single high-efficiency chip, reducing heat, power consumption, and failure points. This design delivers superior reliability, lower operating costs, and higher performance density compared to traditional amplifier architectures. Combined with quiet 51 dBA fan operation and a 2RU chassis design, the MA4-D is a powerhouse built for professional cinema environments.
