3. Setup and Installation
3.1 Unpacking
Carefully remove the amplifier from its packaging. Inspect the unit for any signs of damage that may have occurred during transit. Retain the original packaging for future transport or storage.
3.2 Physical Installation
The DCI2x600N amplifier is designed for rack mounting. It occupies 2U of rack space. Ensure adequate ventilation around the unit. Do not install the amplifier directly above heat-generating equipment without proper spacing.
- Mount the amplifier securely in a standard 19-inch equipment rack using appropriate rack screws.
- Allow at least 1U of empty space above and below the amplifier for optimal airflow, especially in enclosed racks.
- Ensure the front and rear ventilation grilles are unobstructed.
Dimensions: 14.3 x 19 x 3.5 inches (L x W x H)
Weight: 22 Pounds
3.3 Connections
Before making any connections, ensure the amplifier is powered off and disconnected from the mains supply.
3.3.1 Audio Input Connections
Connect your audio source (e.g., mixer, preamplifier) to the amplifier's input connectors. The DCI2x600N typically uses balanced XLR or Phoenix-style connectors for inputs. Refer to the rear panel for specific input types.
3.3.2 Audio Output Connections
Connect your loudspeakers to the amplifier's output terminals. Ensure correct polarity (+ to + and - to -) and that the speaker impedance matches the amplifier's specifications. The DCI2x600N supports various output configurations, including low impedance and 70V/100V constant voltage systems.
3.3.3 Network Connection (N-model)
For network control and monitoring, connect an Ethernet cable from your network switch or router to the amplifier's network port. This allows integration with Harman's HiQnet Audio Architect software.
3.3.4 Power Connection
Connect the supplied AC power cord to the amplifier's IEC inlet and then to a suitable mains power outlet. Ensure the power outlet provides the correct voltage and current rating for the amplifier.

This image displays the amplifier's front face, featuring the Crown logo on the left, a central display panel with LED indicators for Fault, Thermal, Clip, Signal, and Ready states for two channels, and the model number "2 600N DRIVECore INSTALL" on the right. A green illuminated power button is also visible on the far right.
4. Operating Instructions
4.1 Powering On/Off
- Power On: Press the power button located on the front panel. The power indicator will illuminate.
- Power Off: Press and hold the power button for a few seconds until the unit powers down.
4.2 Front Panel Indicators
The central display panel provides visual feedback on the amplifier's status:
- FAULT: Illuminates if a fault condition is detected (e.g., short circuit, DC offset).
- THERMAL: Indicates the amplifier is overheating. The unit may reduce output or shut down to protect itself.
- CLIP: Illuminates when the input signal is too high, causing distortion. Reduce input level to prevent clipping.
- -20dB, -10dB, SIGNAL: These LEDs indicate the input signal level for each channel. The SIGNAL LED illuminates when an audio signal is present.
- READY: Illuminates when the amplifier is powered on and ready to pass audio.
- DATA: (Next to Power button) Indicates network activity for the N-model.
4.3 Network Control and Monitoring
The DCI2x600N amplifier can be controlled and monitored remotely via a network connection using Harman's HiQnet Audio Architect software. This allows for configuration of input/output routing, DSP settings, monitoring of amplifier status, and more.
- Install HiQnet Audio Architect software on a connected computer.
- Discover the amplifier on the network.
- Access and configure amplifier parameters as needed.
5. Maintenance
5.1 Cleaning
Periodically clean the amplifier's exterior with a soft, dry cloth. Do not use liquid cleaners or solvents. Ensure ventilation grilles are free from dust and debris to maintain proper airflow.
5.2 Ventilation
Regularly check that the amplifier's ventilation openings are not obstructed. Proper airflow is crucial for preventing overheating and ensuring long-term reliability.
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power | Power cord disconnected; no mains power; amplifier fuse blown. | Check power cord connection; verify mains power; contact qualified service personnel for fuse replacement. |
| No sound output | Input signal missing; speaker cables disconnected; amplifier in fault mode. | Verify audio source and input connections; check speaker cable connections and polarity; check front panel FAULT indicator. |
| Distorted sound | Input signal too high (clipping); incorrect speaker impedance; faulty speaker. | Reduce input level (check CLIP indicator); verify speaker impedance matches amplifier; test with different speakers. |
| THERMAL LED illuminated | Insufficient ventilation; excessive ambient temperature; prolonged high output. | Ensure proper airflow around the amplifier; reduce ambient temperature; lower output level. |
