Crown Audio DCI 4|1250ND DriveCore Install 4-Channel 1250W Network Display Amplifier with AVB
EAN: 691991008214
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|1250ND, a 1250W DriveCore Install AVB network display 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 2 RU 4/1250ND can produce up to 1250W of output per channel at 2, 4, 8, or 16 ohms or 70 or 100 Vrms. It is equipped with AVB technology, which provides consistent audio and information delivery and is certified by the AVnu Alliance. This digital control allows for networked monitoring, recallable presets. 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|1250ND also has channel-independent high- or low-impedance output that is selectable from onboard LCD screen. This allows you to integrate the amplifier into a variety of different setups.
The front panel of the 4|1250ND provides a series of system indicators, including signal and fault alerts for quick visual monitoring of the system. The LCD screen with the font-panel control knob allows you to enable and select presets and DSP functions in addition to level clip and thermal information. 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.
AVB Digital Audio Transport
Audio Video Bridging (AVB) Ethernet transport ports for easy integration into large AVB systems
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
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 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, overvoltage or undervoltage, and high-frequency overload.
