Crown DCI8X300N-U-USFX 8x300W Power Amplifier

Description

The 300W, high-performance Crown Audio DCI8300N 8-Channel DriveCore Install Series Network Amplifier is designed for system integrators looking for 21st century advanced features for installed sound applications. The amplifier utilizes Harman DriveCore technology, featuring a patented integrated circuit that combines hundreds of discrete circuits into a single chip for lower power, better performance, and improved reliability.

The Class-D amplifier works with impedance loads from 2 to 16 ohms plus 70/100V speakers. The rear panel sports two BLU link connectors capable of delivering 256 channels of digital audio over a standard Cat 5e cable. Additionally, a standard Ethernet connector provides HiQnet Audio Architect control via a Cat 5e port, while the programmable GPIO control port allows for control from analog components such as volume dials.

The onboard digital signal processor provides input/output EQ filters, crossovers, time-alignment delay, and LevelMAX limiters for outstanding protection. Additional protection circuits include shorted outputs, DC, mismatched loads, overheating, over- or under-voltage, and high-frequency overload. The DCI8300N ships with a power cord.
