MA4-D
The DSi 2.0 amplifier family, JBL’s first line of dedicated cinema amplifiers, builds on Crown DSI Digital Screen Array amplifier technology, integrating best-in-class DSP from Crown’s flagship CDi DriveCore series to deliver potent, cost-effective amplification for JBL’s entire range of cinema loudspeakers. Choose from three power configurations, available in analog and analog-plus-digital “D” versions featuring Dante/AES67 connectivity.
Deploy systems faster and easier while streamlining hardware needs: DSi 2.0 amplifiers are designed to meet power requirements of JBL cinema speakers, for a single JBL cinema solution. D-models interface with Dolby Atmos directly, without the need for additional processing hardware. JBL Cinema Speaker presets simplify configuration, optimize playback audio and protect against equipment damage. All DSi 2.0 amps feature SNMP connectivity for networked audio distribution, immersive installations and direct interfacing with third-party theater-management and cinema-control systems.
Models supply 4 channels of amplification with bridgeable outputs in a single 2RU footprint, and can power up to four JBL surround speakers with a single amp channel in high-power-density 2Ω mode. All DSi 2.0 series amps incorporate best-in-class, 32-bit/96kHz floating-point DSP and Crown DriveCore technology, which replaces hundreds of internal components with a single processing chip for superior power density, stability and audio fidelity.
Cinema managers and integrators looking to maximize their power investment and future-proof their systems can count on the JBL DSi 2.0 series to deliver robust, reliable amplification in an efficient, cost-effective package.
