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.

• ANALOG & DIGITAL INPUTS With digital audio transport via HARMANs proprietary BLU-Link, plus balanced analog inputs, DCi gives you a tremendous audio advantage at a much lower cost. The priority input router allows you to specify a primary input, and if audio is lost the amp automatically switches to the other input.
• NETWORK MONITORING & CONTROL Better monitoring, control and audio manipulation with the HiQnet™ protocol thats 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.
