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.

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. -
