Crown International announces the expansion of its CDi Series of professional power amplifiers for installed sound applications with the addition of the CDi 4000.
“With the launch of the CDi 4000, systems integrators now have an even broader range of available power, which extends to 1200 watts per channel into four ohms and 1000 watts per channel for 70-volt distributed systems,” says Stephen Morris, Crown International director of marketing for installed sound, touring, and cinema. “With its advanced technologies and highly competitive price point, the CDi family truly represents an unmatched value in its class.”
Like its siblings, the CDi 1000 and CDi 2000, the high-performance CDi 4000 is equipped with a host of sophisticated features, not the least of which is its versatile ability to run both low-impedance two-, four-, and eight-ohm loads as well as 70- and 140-volt outputs.
An intuitive front panel LCD enables installers to quickly step through the process of tailoring system parameters for onboard loudspeaker processing (including crossovers, EQ, limiting, compression, and delay), while 20 user-defined DSP presets ensure that those settings can be easily recalled at the touch of a button. A rear-panel USB connector further permits the amplifier to be configured and controlled via a PC running Harman Pro’s HiQnet™ System Architect™ software.
Equipped with Crown’s extremely light and efficient universal switch-mode power supply, each of the three CDi models weighs only 19 pounds despite being housed in a rugged steel 2U chassis and can be run off of a standard 15-amp outlet.
Advanced protection circuitry guards against shorted outputs, open circuits, DC, mismatched loads, general overheating, high-frequency overloads, and internal faults. Quiet proportional-speed fans help keep the amplifiers cool under rigorous operating conditions, and a number of front-panel LEDs (signal, -10, -20, ready, clip, temp/fault, and power) help provide the system operator with an immediate visual of current amplifier status and performance.
Rear-panel connectivity includes detachable Phoenix-style input connectors, barrier strip output connectors, and a NEMA 5-15P inlet for AC mains.
Power output ratings on the CDi 4000 are as follows:
· 1600W per channel at two ohms
· 1200W per channel at four ohms
· 650W per channel at eight ohms
· 1000W per channel at 70V
· 3200W in bridge-mono mode at four ohms
· 2000W in bridge-mono mode at 140V
The CDi 4000 carries a suggested US list price of $1,800.
