Crown DCi 8|300 - 300W 8-Channel at 4-Ohm 70V/100V Analog Power Amplifier

The Crown DCi 8|300 is a highly versatile 8-channel analog power amplifier that delivers 300W per channel at 4 ohms, making it ideal for professional installed sound applications such as multi-zone distributed audio systems in venues like cinemas, houses of worship, hotels, and retail spaces. Designed to meet the high demands of modern installations, this amplifier offers advanced features and superior performance while maintaining a compact, energy-efficient form factor. The DCi 8|300 is part of Crown's renowned DriveCore Install Series, which integrates cutting-edge Class D amplification technology with industry-leading efficiency and reliability.

At the heart of the DCi 8|300 is Crown's proprietary DriveCore technology, which consolidates hundreds of discrete components into a single chip. This innovation results in enhanced performance, lower power consumption, and increased long-term reliability. The amplifier's signal-to-noise ratio exceeds 108dB, ensuring pristine audio clarity even at higher volumes, while its Total Harmonic Distortion (THD) remains low at 0.35%, ensuring accurate reproduction of both music and voice.

The DCi 8|300 features Direct Drive capabilities, allowing each channel to individually support low-Z (2, 4, 8 ohm) or high-Z (70V, 100V) operation without the need for step-up transformers. This makes the amplifier ideal for installations that require constant voltage systems, where it can drive large numbers of speakers while maintaining sound quality. The flexibility to switch between low and high impedance on a per-channel basis makes this amplifier exceptionally versatile for a wide range of installation scenarios.

With advanced protection circuits, the DCi 8|300 ensures that both the amplifier and connected speakers are safeguarded against common issues such as short circuits, overheating, DC offset, mismatched loads, and high-frequency overload. Crown's TLC (Total Linear Control) protection further enhances reliability by applying intelligent gain reduction when needed to prevent overheating, allowing continuous operation under challenging conditions. This level of protection makes the DCi 8|300 an incredibly dependable solution for demanding installations that require round-the-clock operation.

Energy efficiency is a key focus of the DCi 8|300, featuring several power-saving modes. The amplifier consumes less than 1W of power in sleep mode, and an auto-standby feature automatically activates after 30 minutes of no input signal, significantly reducing energy consumption during idle periods. Additionally, the amplifier can be remotely powered on or off via its AUX port, offering convenient integration into control systems. These energy-saving features, along with Crown's Green Edge compliance, make the DCi 8|300 an environmentally friendly and cost-effective option for long-term installations.

The DCi 8|300's cooling system utilizes continuously variable-speed forced air that directs airflow from front to back, focusing on areas that generate the most heat. This maximizes cooling efficiency while minimizing noise, with a maximum fan noise level of 47 dB, making it suitable for environments where quiet operation is important, such as conference rooms and theaters.

Installation of the DCi 8|300 is made easy with its 2U rackmount design, measuring 19 x 14.24 x 3.5 inches and weighing just 23.5 lbs. This compact size allows the amplifier to fit seamlessly into standard equipment racks, saving space while delivering exceptional power and performance. For connectivity, the amplifier offers barrier strip outputs for low-Z or high-Z speaker systems and removable Phnix-style inputs, ensuring straightforward installation and flexibility.

The Crown DCi 8|300 is equipped with advanced PFC (Power Factor Correction) technology in its power supply, ensuring efficient power delivery regardless of fluctuating mains voltages. This universal AC input accepts 100V-240V, 50/60Hz, making the amplifier suitable for global installations. With its robust feature set, reliable performance, and energy efficiency, the DCi 8|300 is a top choice for professional sound integrators looking for a high-quality, multi-channel amplifier for complex audio installations.
