Choose from three power configurations, available in analog and analog-plus-digital “D” versions featuring Dante\/AES67 connectivity.\u003cbr\u003e\u003cbr\u003eDeploy 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.\u003cbr\u003e\u003cbr\u003eModels 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.\u003cbr\u003e\u003cbr\u003eCinema 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.\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"product-features\" class=\"row product-subheader\"\u003e\n\u003cdiv class=\"small-10 columns\"\u003e\n\u003cp class=\"content-nav\" data-magellan-destination=\"features\"\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv id=\"panel_features\" class=\"product_main_tab_content content \"\u003e\n\u003cdiv class=\"features text-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eEach amp offers 4 channels with bridgeable outputs to easily power JBL’s entire line of cinema speakers.\u003c\/li\u003e\n\u003cli\u003eAmplifiers are engineered to meet exact power requirements of JBL cinema speakers, for a single JBL cinema solution.\u003c\/li\u003e\n\u003cli\u003eA new amplifier design allows for high power output at 2Ω (SA and MA models), enabling up to 4 surround speakers to be powered by a single channel.\u003c\/li\u003e\n\u003cli\u003eD-models interface with Dolby Atmos directly, without the need for additional processing hardware.\u003c\/li\u003e\n\u003cli\u003eAll models feature SNMP and ethernet connectivity for networking and third-party control;
