The DSi 2.0 amplifier family, JBL’s first line of dedicated cinema amplifiers, builds on Crown DSi Digital Screen Array amplifier technology and best-in-class DSP from Crown’s flagship CDi DriveCore Series to deliver potent, efficient amplification and top-notch processing for JBL’s entire range of cinema loudspeakers. Cinema managers and integrators looking to maximize their power investment and future-proof their systems can count on JBL DSi 2.0 Series to deliver robust, reliable performance in an ultra-efficient package.

BEST-IN-CLASS DSP

DSi 2.0 amplifiers feature best-in-class, 96kHz/32-bit floating point internal processing with delay (up to 1,000 ms), 8-band parametric EQ, crossover, FIR processing, LevelMAX™ limiting and more, eliminating the need for an external processor.

SUPERIOR POWER DENSITY MEANS BETTER VALUE

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 2U footprint. Using high-output 2Ω mode allows powering of up to 4 surround speakers from a single channel.

DEDICATED JBL SPEAKER TUNINGS

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. 

REMOTE MONITORING AND MANAGEMENT

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.

AUDIO NETWORKING (SA4-D, MA4-D AND LA4-D MODELS)

AES67 connectivity allows networked audio distribution from any Dante/AES67-compatible device and direct interfacing with Dolby Atmos Connect interfaces.* Dual network audio ports support primary and secondary networks configured as switched (daisy chain) or redundant (star) systems.
