About Crown Audio MA4
The JBL MA4 DSi 2.0 Series Next-Generation Amplifier is a groundbreaking innovation in the realm of cinema audio technology. As the first dedicated cinema amplifier line from JBL, it leverages the superior Crown DSI Digital Screen Array amplifier technology, seamlessly integrating top-tier DSP from Crown's renowned CDi DriveCore series. This powerful combination ensures robust, cost-effective amplification for the entire spectrum of JBL cinema loudspeakers.
Available in three power configurations, the MA4 DSi 2.0 Series offers both analog and enhanced analog-plus-digital "D" versions. The latter boasts Dante/AES67 connectivity, facilitating the deployment of systems swiftly and efficiently, while minimizing hardware requirements. These amplifiers are meticulously designed to meet the power demands of JBL cinema speakers, providing a unified JBL cinema solution.
The D-models in the series offer direct interfacing with Dolby Atmos, eliminating the need for additional processing hardware. Furthermore, the inclusion of JBL Cinema Speaker presets simplifies configuration, optimizes audio playback, and safeguards against potential equipment damage.
All MA4 DSi 2.0 amplifiers feature SNMP connectivity, enabling networked audio distribution, immersive installations, and seamless interfacing with third-party theater-management and cinema-control systems. Each model provides four channels of amplification with bridgeable outputs in a compact 2RU footprint. They are capable of powering up to four JBL surround speakers with a single amp channel in a high-power-density 2 Ohm mode.
The MA4 DSi 2.0 series amplifiers are equipped with best-in-class, 32-bit/96kHz floating-point DSP and Crown DriveCore technology. This replaces hundreds of internal components with a single processing chip, enhancing power density, stability, and audio fidelity. For cinema managers and integrators aiming to optimize their power investment and future-proof their systems, the JBL MA4 DSi 2.0 Series Next-Generation Amplifier offers a robust, reliable solution in an efficient, cost-effective package.
