    Three Year, No-Fault Transferable Warranty – Your investment is fully protected. • Complies with Green Edge by Harman – Environmentally friendly practices in design, manufacturing, and packaging complement energy-efficient operation. • PFC Power Supply – the next generation power supply design guarantees minimum rated power delivered for drastically lower current draw.
  • Page 6: Installation

    DCi Series Power Amplifiers Installation Unpacking Unpack your amplifier and inspect for any damage that may have occurred during transit. If damage is found, notify the shipping company immediately. Only you can initiate a claim for shipping damage, though Crown will be happy to help as needed. If the product arrived showing signs of damage, save the shipping carton for the shipper’s inspection.
  • Page 7: Set-Up And System Configuration

    DCi Series Power Amplifiers Set-up and System Configuration Figure 3 Wire Input Connectors Crown recommends using pre-built or professionally wired balanced line (two-conductor plus shield). Balanced wiring provides better rejection of unwanted noise and hum; however, unbalanced line may also be used. For more information, refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.
  • Page 8 DCi Series Power Amplifiers Set-up and System Configuration Connect Loudspeakers and Configure for Loudspeaker Load Determine load impedances and power requirements Before making any connections, carefully check and review the total impedance for loudspeaker systems to be connected to each amplifier output. If multiple loudspeakers are connected to one output (in series, parallel or series-parallel) for Lo-Z operation, be certain the total system impedance is within allowed specification for the output.
  • Page 9 DCi Series Power Amplifiers Set-up and System Configuration Bridge Mode (16, 8, or 4 Ohm) Typical input and output wiring, along with Attenuator and Mode DIP Switch settings are shown in Figure 7. Make sure the “Hi-Z” selector switches are in the OFF (down) position and the Bridge (BRG) switch is in the ON (up) position.
  • Page 10 DCi Series Power Amplifiers Set-up and System Configuration Dual Mode Hi-Z (70V/100V) Typical input and output wiring, along with Attenuator and Mode DIP Switch settings are shown in Figure 8. Make sure the “Hi-Z” selector switches are in the ON (up) position and the Bridge (BRG) switch is in the OFF (down) position.
  • Page 11 DCi Series Power Amplifiers Set-up and System Configuration Bridge Mode Hi-Z (140V/200V) Typical input and output wiring, along with Attenuator and Mode DIP Switch settings are shown in Figure 9. Make sure the “Hi-Z” selector switch for the connected input channel is in the ON (up) position and the Bridge (BRG) switch for the channel pair also is in the ON (up) position.

    DCi Series Power Amplifiers Front Panel Features Indicators: Fault Indicator (red): Flashes when the amplifier output channel has stopped operating. (See Page 16 Troubleshooting.) Power Indicator (blue) Thermal Indicator (red): Illuminates when the channel reaches 80 degrees Celsius, indicating the onset of protection compression.
  • Page 14: Global & Per Channel Settings

    DCi Series Power Amplifiers Global Settings 70/100 VRMS (switch A) This switch selects either 70 or 100 VRMS operation for all outputs currently selected for Hi-Z mode. (See the section below, Hi-Z.) Default position is 70 V (OFF). In 70 V and 100 V mode, a voltage limiter circuit is enabled.
  • Page 15: Protection System

    DCi Series Power Amplifiers Protection System Thermal Indicator If the amplifier becomes too hot for safe operation, the channel that is generating too much heat will be shut down until the temperature drops below the thermal limit. The front-panel thermal indicator will illuminate at 80 degrees Celsius, indicating the onset of compression affecting the audio signal. The amplifier will continue to run in this state until either the temperature is reduced to a safe operating range, or if the temperature continues to rise, the channel will shut off to protect itself above 98 degrees Celsius.
