Commercial Audio Series Amplifiers 2 Setup 2.1 Installation 2.2 How to Attach Rack Ears CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with the power switch in the “off” position and all level controls turned completely down (counterclockwise). 1. Locate the two rack ears and two rack-ear screws supplied. 2. See Figure 2.2. Remove the two screws from each side of the chassis near the front. 3. Place a rack ear flush with the right front of the chassis. 4.
Commercial Audio Series Amplifiers 2 Setup 2.3 Choose Input Wire and Connectors Crown recommends using pre-built or professionally wired balanced line (two-conductor plus shield), 22-24 gauge cables and connectors. You should use 3-pin Phoenix-type cable ends at the amplifier inputs. Unbalanced line may also be used but may result in noise over long cable runs. Figure 2.3 shows connector pin assignments for balanced wiring, and Figure 2.4 shows connector pin assignments for unbalanced wiring.
Commercial Audio Series Amplifiers 2 Setup 2.5 Wire Your System Typical input and output wiring for the 180A, 280A and 1160A is shown in Figure 2.7. See Figure 2.8 for 660A wiring. INPUTS: Connect balanced line-level sources to amplifier balanced inputs. OUTPUTS: Maintain proper polarity (+/–) on output connectors. Ceiling Speakers For each amplifier channel, connect the Amplifier Output screw terminals to the loudspeaker loads.

Commercial Audio Series Amplifiers 2 Setup 2.6 Remote Volume Control 2.7 Powering Up You can control the volume of each amplifier channel remotely. To do so, locate the OUTPUT VCA connector on the back panel. Insert a 4-pin Phoenix-type cable connector into the OUTPUT VCA connector. Wire a Crown 1-VCAP or 4-VCAP level control to the Phoenix-type cable connector terminals as shown in Figure 2.11. 1. Turn off any equipment connected to the Line Out connectors. 2.
Commercial Audio Series Amplifiers 3 Troubleshooting CONDITION: No power to the amplifier. POSSIBLE REASON: • The amplifier’s Power switch is off. • The amplifier is not plugged into the power receptacle. • The amplifier’s high-voltage power supply circuit breaker has tripped, or the fuse has opened on 220/230/240V models. Verify that the AC mains voltage is correct, then press the Reset button on the back panel. • If the unit is operated from a 24V DC supply, the internal fuse may have opened.
