DCi Series Power Amplifiers Welcome Thank you for purchasing a new Crown DriveCore install ™ Series installation amplifier, one in a complete line of high-performance amplifiers based on exclusive DriveCore™ technology. DCi Series amplifiers are designed, engineered and manufactured to the industry’s highest quality standards, and provide system integrators with the advanced features and flexibility required for challenging 21st century installed sound applications.
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. We also recommend that you save all packing materials for use if you ever need to transport the unit.
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. Use 6-pin plug-in cable ends at the amp input connectors.
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.
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. NOTE: Only the Hi-Z selector switches assigned to odd-numbered channels (1,3,5,7) are active in Bridge mode; switches assigned to even-numbered channels (2,4,6,8) are disabled.
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. A 35Hz high pass filter is selected automatically when the amplifier channel is in Hi-Z or Bridged Hi-Z mode.
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. A 35Hz high pass filter is selected automatically when the amplifier channel is in Hi-Z or Bridged Hi-Z mode.
DCi Series Power Amplifiers Set-up and System Configuration Connect to AC Mains Connect your amplifier to the AC mains power source (power outlet) using the supplied AC power cord set. First, connect the IEC end of the cord set to the IEC connector on the amplifier; then, plug the other end of the cord set to the AC mains. WARNING: The third prong of this connector (ground) is an important safety feature. Do not attempt to disable this ground connection by using an adapter or other methods.
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. Illuminates when the amplifier is ON and acceptable AC line voltage is present.
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. NOTE: When bridged Hi-Z mode is implemented, selected voltages are doubled to 140V or 200V.
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.
DCi Series Power Amplifiers Troubleshooting CONDITION: Power indicator is off. Mains indicator is on. POSSIBLE REASON • The amplifier’s Power switch is off. “Off/Flashing/On” above means that the LED can be off, or flashing, or on. CONDITION: Power indicator is off. Mains indicator is off. POSSIBLE REASON • The power supply fuse has tripped. • The amplifier has lost AC Power. • The amplifier is not plugged in to the power receptacle. CONDITION: Power indicator is flashing.
DCi Series Power Amplifiers Troubleshooting CONDITION: Distorted sound. POSSIBLE REASON: • Load is wired incorrectly or Stereo/Bridge mode switch is set incorrectly. Check both. • Input is overloaded by a signal level that is too high. Turn down your amplifier level controls, or turn down the input signal, until the clip light goes out. Note: If the signal sounds distorted even though the Clip LED is off, the input signal may be distorted before it reaches the amplifier input.
DCi Series Power Amplifiers Troubleshooting CONDITION: No input signal. Signal indicator is not flashing even though audio is applied, and the channel is ready.. POSSIBLE REASON: • Input signal level is very low. “Off/Flashing/On” above means that the LED can be off, or flashing, or on. CONDITION: Bridge LED is lit. POSSIBLE REASON: • page 18 Amplifier is in bridge-mono mode.
