System integrators working on challenging 21st century installed sound applications require equipment that is versatile, compact, and highly efficient. Look no further than the 4-channel Crown Audio DCI 4|2400N, a 2400W DriveCore Install BLU Link network amplifier with advanced features and flexibility. The amplifier provides analog and digital inputs, network monitoring and control, programmable General Purpose Input/Output (GPIO) ports, and on-board Digital Signal Processing (DSP). The amplifier also meets EN 54-16 compliance for life safety systems to serve the needs of hospitality, large venues, and other markets.

The 2 RU 4/2400N can produce up to 2400W of output per channel at 2, 4, 8 or 16 ohms or 70 or 100 Vrms. It is compatible with Harman’s BLU Link digital audio transport and accepts digital inputs via its rear-panel RJ-45 connectors. This digital control allows for networked monitoring, recallable presets, and the setup of secondary inputs that engage if the primary inputs fail. The built-in DSP capabilities include limiting, input/output EQs, delay, and a matrix mixer.

Each channel pair can be bridged for powering higher power applications such as a subwoofer. The 4|2400N also has channel-independent, high- or low-impedance output that is selectable from the rear-panel DIP switches. This allows you to integrate the amplifier into a variety of different setups. Each of its 4 channels additionally features independent attenuators with a range from 0 to -80 dB.

The front panel of the 4|2400N provides a series of system indicators, including level and signal, ready, clip, thermal, and fault alerts for quick visual monitoring of the system. The unit can be integrated into a control system for powering on and off as well as engaging its sleep mode for saving energy when not in use.

Network Monitoring & Control
Monitoring, control and audio manipulation are provided with the HiQnet protocol that’s over standard TCP/IP. Remotely see how all networked DCi amplifiers are performing and control them as needed. In addition, this allows Audio Architect software and the Powered by Crown app to work with DCi amplifiers.
Programmable General Purpose Input/Output Ports
GPIO ports can be configured in many different ways, such as volume controls, recall presets, or to report errors to a master computer
DSP includes LevelMAX limiters, input/output EQ, delay, matrix mixer, and speaker line monitoring
Direct Drive Constant Voltage
You can use smaller-gauge wiring to drive the speakers using either 70/100 Vrms. With no need for a step-up transformer at the output, the DCi produces audio more efficiently
Channel-Independent Hi-Z/Low-Z Selection
Drive either one to four speakers in low-Z mode, or literally hundreds of speakers in hi-Z mode (70 Vrms or 100 Vrms). This means design flexibility since DCi powers all loads on a channel-by-channel basis
Bridgeable Channel Pairs
The DriveCore Install Series channels are bridgeable, even in 100 Vrms mode, allowing them to be used to for higher-power applications like subwoofers
Remote On/Off Interface
The amplifier can be integrated into a control system for remote on/off control
Efficient Cooling Design
Efficient internal cooling fans provide airflow to the most heat-generating parts. Incorporating the fans into the amplifier brick design maximizes cooling while minimizing wasted energy and noise
Auto Standby
The amplifier automatically goes into sleep mode after 30 minutes of no input signal
TLC Protection
The amp has built-in protection from excessive heat by applying gain reduction when necessary
Advanced Protection Circuits
Amplifier and loads are protected against shorted outputs, DC, mismatched loads, overheating, over- or under-voltage, and high-frequency overload
