This 2U rackmount amplifier is designed to drive the largest and most complex speaker configurations, delivering a staggering 1200 watts per channel at 4 ohms. Its ability to support both low-impedance loads and high-impedance 70V\/140V distributed systems makes it a versatile powerhouse for stadiums, large retail complexes, and expansive luxury estate audio networks.\u003cbr\u003e\u003cbr\u003eEquipped with a sophisticated onboard Digital Signal Processing (DSP) suite, the CDi 4000 provides absolute control over every aspect of your sound. The system features high-precision crossover filters, EQ, and peak voltage limiting to ensure your speakers perform at their best while remaining protected from over-excursion. These settings can be managed directly via the front-panel backlit LCD or through a computer via the USB-B port, allowing for detailed system tuning and the creation of custom presets for different zones or speaker types.\u003cbr\u003e\u003cbr\u003eDurability and protection are standard with Crown’s professional engineering. The CDi 4000 includes robust safeguards against short circuits, open circuits, and thermal overloads, ensuring uptime in mission-critical environments. A proportional speed fan provides efficient, quiet cooling even when the amplifier is pushed to its maximum limits. With balanced block inputs and high-current barrier strip outputs, the CDi 4000 is a dependable, top-tier solution for any large-scale permanent audio installation.\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top:25px; margin-bottom:10px;\"\u003eKey Features\u003c\/h2\u003e\n\u003ch3\u003eMaximum Power Performance\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSupports 2, 4, and 8-ohm loads plus 70V and 140V distributed systems\u003c\/li\u003e\n\u003cli\u003eDelivers 1200W per channel at 4 ohms and 1000W at 70V\u003c\/li\u003e\n\u003cli\u003eBridgeable output provides up to 3200W at 4 ohms for extreme power requirements\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eIntegrated Professional DSP\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eOnboard processing includes EQ, crossovers, delay, and output limiting\u003c\/li\u003e\n\u003cli\u003eFront-panel LCD screen for instant monitoring and preset navigation\u003c\/li\u003e\n\u003cli\u003eUSB connectivity for comprehensive system management and software tuning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eCommercial Build Quality\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStandard 2U rackmount chassis with professional barrier strip terminals\u003c\/li\u003e\n\u003cli\u003eAdvanced thermal protection and proportional speed cooling fan\u003c\/li\u003e\n\u003cli\u003eCircuitry protection against shorts, DC faults, and open circuits\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003ePower Output\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eChannels: 2\u003cbr\u003e\u003cbr\u003ePower @ 2 Ohms: 1600 Watts x 2\u003cbr\u003e\u003cbr\u003ePower @ 4 Ohms: 1200 Watts x 2\u003cbr\u003e\u003cbr\u003ePower @ 8 Ohms: 650 Watts x 2\u003cbr\u003e\u003cbr\u003e70V Output: 1000 Watts x 2\u003cbr\u003e\u003cbr\u003eBridged Power: 3200 Watts @ 4 Ohms \/ 2000 Watts @ 140V\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eAudio Performance\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eFrequency Response: 20 Hz – 20 kHz (+0\/-1 dB)\u003cbr\u003e\u003cbr\u003eSignal-to-Noise Ratio: 100 dBA\u003cbr\u003e\u003cbr\u003eTotal Harmonic Distortion (THD): ≤ 0.5%\u003cbr\u003e\u003cbr\u003eDamping Factor: \u0026gt; 500\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003ePhysical \u0026amp; Power\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eRack Size: 2U\u003cbr\u003e\u003cbr\u003eDimensions: 19 x 12.3 x 3.5 in\u003cbr\u003e\u003cbr\u003eWeight: 19 lb \/ 8.6 kg\u003cbr\u003e\u003cbr\u003eCurrent Consumption: 10.5 A\u003cbr\u003e\u003cbr\u003eInput Connectors: 2x 3-Pin Balanced Block\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\n\u003ch5\u003eFAQ\u003c\/h5\u003e\n\u003ch3\u003eIs this amplifier too powerful for a standard backyard system?\u003c\/h3\u003e\n\u003cp\u003eThe CDi 4000 is intended for very large properties or systems with a high volume of speakers.
