Crown Audio CDi 1000 Two-Channel Power Amplifier - 500W per Channel, 70V/140V Support, Integrated DSP

Product Description The Crown Audio CDi 1000 is a robust and highly versatile power amplifier engineered for the demanding requirements of commercial and residential audio systems. Part of the renowned CDi series, this 2U rackmount amplifier provides consistent and clean power for both low-impedance and 70V/140V distributed audio systems. With 500 watts per channel at 4 ohms, it is powerful enough to drive complex speaker arrays in restaurants, retail environments, and large-scale residential outdoor systems. At the core of the CDi 1000 is its integrated Digital Signal Processing (DSP), which offers comprehensive control over your audio environment. The DSP suite includes crossover filters, delay, and output limiting, allowing you to fine-tune the performance of your speakers and protect them from damage. These settings are easily manageable via the intuitive backlit LCD screen on the front panel or through a computer connection using the HiQnet Audio Architect software. This level of control ensures that your audio system sounds balanced and professional, regardless of the room's acoustics. Reliability is a hallmark of Crown engineering, and the CDi 1000 is built to last. It features advanced protection circuitry against shorted outputs, open circuits, and DC levels. The cooling system includes a proportional speed fan to maintain optimal operating temperatures during extended use. With versatile input and output options, including balanced block inputs and barrier strip outputs, the CDi 1000 is a dependable, high-performance centerpiece for any permanent audio installation.

Yes, the CDi 1000 is an excellent choice for landscape systems like the Sonance Garden Series, as it can handle the low-impedance or 70V requirements of multiple outdoor satellites and subwoofers. Is the software required to use the DSP? While the front-panel LCD allows for many basic adjustments and preset selection, the free software via USB provides a much more detailed interface for precise EQ and system tuning. Does it come with rack ears? Yes, the amplifier is built into a standard 19-inch rackmount chassis, making it ready to be secured into any standard audio equipment rack.
