Product Description
The Crown Audio CDi 4000 represents the pinnacle of the CDi series, offering unrivaled power and flexibility for professional audio installations. 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.
Equipped 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.
Durability 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.

Is this amplifier too powerful for a standard backyard system?
The CDi 4000 is intended for very large properties or systems with a high volume of speakers. For standard residential patios or smaller gardens, the CDi 1000 or 2000 models often provide sufficient power.
Can I run a subwoofer on one channel and satellites on the other?
Yes. Because the DSP can be configured independently for each channel, you can apply a low-pass filter to one channel for a subwoofer and a high-pass filter to the other for satellites.
What software is used to tune this amplifier?
The CDi series is compatible with HiQnet Audio Architect software, which allows for advanced control over the EQ, limiting, and crossover settings via the USB connection.
