DCI4X300
4CH POWER AMPLIFIER 300W @ 4 OHM ANALOG, 70V 100V, INTEGRATED DSP

The Crown DCi 4|300 is a four-channel installation-grade power amplifier delivering 300 watts per channel at 4O, with selectable 70V and 100V operation for distributed audio systems. Designed for commercial and professional AV environments, the DCi 4|300 combines high output power, flexible channel routing, and efficient Class D amplification in a compact 2RU rackmount chassis.

Part of Crown’s DriveCore™ Install (DCi) Series, this amplifier is optimized for fixed installations such as corporate facilities, hospitality venues, houses of worship, education campuses, and large retail environments. Each channel can be independently configured for low-impedance or high-impedance operation, allowing integrators to mix 4/8O speakers and 70V/100V distributed lines within the same amplifier.

Advanced DSP control is available through Harman’s HiQnet Audio Architect™ software platform, enabling remote configuration, monitoring, load supervision, and fault reporting. With high channel density, reliable thermal performance, and energy-efficient design, the DCi 4|300 is engineered for scalable, network-controlled audio systems where performance and uptime are critical.

DCi Amplifier Series Features

·         TRUE RACK DENSITY – Power points of 300W or 600W in 2-/4-/8-channel configurations – all in a 2 Rack Unit form factor. More channels in one box allow smaller infrastructure rooms that can reduce operational costs while giving you the utmost in installation flexibility.

·         DIRECT DRIVE CONSTANT VOLTAGE – Save money by using smaller gauge wiring to drive the speakers using either 70V rms or 100Vrms. With no need for a step-up transformer at the output, the DCi produces higher audio quality much more efficiently.

·         CHANNEL INDEPENDENT HI-Z/LOW-Z SELECTION – Drive either one or two speakers in low-Z mode, or literally hundreds of speakers in high-Z mode (70Vrms or 100Vrms). This means better design flexibility since DCi powers all loads on a channel-by-channel basis.

·         BRIDGEABLE CHANNEL PAIRS – Unlike amps from other manufacturers, the DCi Series channels are bridgeable – even in 100Vrms mode – which means even more adaptability for higher power applications such as subwoofers.

·         REMOTE ON/OFF INTERFACE – Save power by integrating the amplifier into a control system so you can easily turn it on and off.

·         EFFICIENT COOLING DESIGN – Highly efficient internal cooling fans provide airflow to the most heat-generating parts. Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise.

·         ADVANCED POWER FACTOR CORRECTION (PFC) UNIVERSAL POWER SUPPLY – The most advanced power supply in an installation amplifier delivers power more efficiently in almost any condition than anyone else, resulting in less power dissipated and less heat in your racks.
