Crown CDi 1000 - 500W 2-Channel at 4-Ohm 70V/140V Power Amplifier

The Crown CDi 1000 is a highly versatile 2-channel power amplifier designed for professional installed sound applications, offering 500W per channel at 4 ohms and 70V/140V configurations. Part of the Crown CDi Series, this amplifier delivers robust performance for a wide range of venues, including houses of worship, theaters, restaurants, and retail spaces. Built with Crown's signature durability and reliability, the CDi 1000 is rugged, lightweight, and optimized for permanent installations, making it an unmatched value in its class.

One of the standout features of the CDi 1000 is its intuitive front-panel LCD screen, which simplifies configuration and setup, guiding installers through all key adjustments. This interface allows easy access to the amplifier's onboard Digital Signal Processing (DSP) capabilities, which include advanced features such as crossovers, EQ filters, delay, and output limiting. These processing tools enable installers to tailor the amplifier's performance to suit the specific acoustic needs of the venue, ensuring optimal sound quality.

Another key feature of the CDi 1000 is its switch-mode universal power supply, which ensures reliable performance in any global power setting, whether it's 100V or 240V. This makes the amplifier suitable for international installations, providing flexibility and peace of mind for integrators and users alike. The amplifier also features proportional-speed fan-assisted cooling, keeping the unit cool during operation while minimizing noise-an important factor for quiet environments like houses of worship or theaters.

The CDi 1000 offers an impressive range of output configurations, supporting both low-impedance (2, 4, and 8 ohms) and high-impedance (70V and 140V) speaker systems, making it incredibly versatile for distributed audio installations. The amplifier provides 700W at 2 ohms, 500W at 4 ohms, and 275W at 8 ohms in dual-mode operation. In bridge-mono mode, it delivers 1400W at 4 ohms and 1000W at 8 ohms or 140Vrms, making it suitable for a variety of speaker setups.

The Crown CDi 1000 also comes equipped with barrier strip outputs for low-impedance or 70V/140V loads, ensuring secure connections in permanent installations. The amplifier's removable Phnix-style inputs provide easy integration with various audio sources, further enhancing its adaptability in different installation environments. Additionally, advanced protection circuitry is built into the unit to safeguard against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads, and internal faults, ensuring long-term reliability.

With a focus on delivering accurate, uncolored sound, the CDi 1000 boasts a low total harmonic distortion of less than 0.05%, providing clear and distortion-free audio, whether used for music or voice reproduction. It has a signal-to-noise ratio of 100dB and a damping factor greater than 500, which ensures tight control of speakers, particularly in low-frequency ranges, for superior audio clarity and fidelity.

The CDi 1000 fills 2U of rack space and weighs a manageable 22 lbs, making it a space-efficient and easy-to-handle addition to any professional audio rack setup. Its compact dimensions of 19 x 12.5 x 3.5 inches allow it to fit seamlessly into standard 19-inch equipment racks, ensuring a clean and organized installation.
