Cinema managers and integrators looking to maximize their power investment and future-proof their systems will be thrilled with the Crown Audio DSi-Series MA4, a 700W 4-channel power amplifier that's designed for JBL cinema loudspeakers offering outstanding quality and performance in a rack-mountable enclosure.

The amplifier features a remarkable 96 kHz/32-bit digital signal processing with delay, 8-band parametric EQ, crossovers, FIR processing, LevelMAX limiting, and more. The integrated DriveCore technology incorporates hundreds of amplifier components into a single chip for superior efficiency and reliability. With its updated design, the MA4 allows for high power output at 2 ohms, enabling up to four surround speakers to be powered by a single channel. There are built-in cinema speaker tuning presets that match all JBL cinema loudspeakers for optimal performance, protection, and easy deployment.

The font panel features an LCD and encoder to configure amplifier settings and mute channels at the touch of a button. The rear panel provides four analog inputs via two Euroblock connectors and two terminal strip speaker outputs to connect up to four speakers. A HiQnet (RJ45) port allows the amplifier to connect with HARMON Audio Architect control software over a standard TCP/IP network. A GPIO/AUX port allows you to externally recall presets, mute channels, monitor amplifier health and power the amplifier on or off.

Crown's patented DriveCore technology seamlessly integrates the amplifier drive stage into the power output stage, fusing everything into one powerful chip to deliver greater efficiency, reliability, and performance. Using DriveCore, DSi 2.0 amps deliver greater power density than traditional designs, offering 4 channels of amplification with bridgeable outputs in a single 2 RU footprint. Using high-output 2-ohm mode allows powering of up to 4 surround speakers from a single channel.

Built-in JBL cinema speaker tuning presets manage voltage and frequencies delivered to transducers, maximizing system efficiency, and optimizing audio signal quality while preventing equipment damage and accelerating deployment.

SNMP connectivity for interfacing with third-party theater management systems and Cinema Control (NOC) systems for remote status and fault monitoring. A HiQnet port provides access to HARMAN's Audio Architect software, for controlling, configuring, and monitoring amplifier operation through a standard TCP/IP network. A combined GPIO/AUX port can be used to externally recall presets, mute channels, monitor amplifier health, and power the amplifier on and off.
