NOTE: Custom wiring should only be performed by qualified personnel. 3.5 Choose Output Wire and Connectors A protective cover is installed over the barrierstrip output. Some models have a cover with two holes. To remove this type of cover: 1.
CTs Power Amplifiers 3 Setup CTs Power Amplifiers 3 Setup 3.6.3 Dual 70V/100V Mode Typical input and output wiring, along with Attenuator and Mode Switch settings are shown in Figures 3.10 and 3.11. Make sure the Mode switch is set to the “Dual” position when operating in Dual mode. 3.6.5 Dual Mode with “Y” Input See Figure 3.14. This configuration feeds a mono signal to both Channel 1 and Channel 2. In the example in Figure 3.
CTs Power Amplifiers 3 Setup CTs Power Amplifiers 4 Operation 3.7 Connect to AC Mains On the back panel, check whether your amplifier is labeled for 120V or 220-240V AC mains. Connect your amplifier to the corresponding AC mains power source (power outlet) with the supplied AC power cordset. First, connect the IEC end of the cordset to the IEC connector on the amplifier. Then, with the amplifier in the OFF position, plug the other end of the cordset into the AC mains.

CTs 600/1200 look slightly different near the Reset button. M. Power Cord Connector Standard 15 amp IEC inlet. A circuit breaker located near the IEC power inlet protects the amplifier from excessive AC current draw. N. Reset Switch Resets the circuit breaker that protects the power supply. O. Ventilation Grille Air flow is front to back.
CTs Power Amplifiers 5 Advanced Features and Options 5.2.4 Input Sensitivity Switches See Figures 5.1 and 5.2. To access the Input Sensitivity Switches, turn off the amplifier and remove the PIP2-BBY Input Panel. The switches are in the top surface of the cavity behind the Input Panel. One 3-position switch per channel selects among these settings: CTs 600/1200: 1.4V (8/4 ohms), 26 dB gain, and 1.4V (70V operation). CTs 2000/3000: 1.4V (8/4 ohms), 26 dB gain, and 1.4V (70V) / 2V (100V).
CTs Power Amplifiers 6 Troubleshooting CTs Power Amplifiers 6 Troubleshooting CONDITION: Power indicator is off. POSSIBLE REASON CONDITION: Fault indicator is flashing. • The amplifier has lost AC power. POSSIBLE REASON: • The amplifier’s Power switch is off. • • The amplifier is not plugged into the power receptacle. • The amplifier output level is so high that the power supply circuit breaker has tripped. Allow the unit to cool. Turn down the Level controls.

CTs Power Amplifiers 9 Service Crown amplifiers are quality units that rarely require servicing. Before returning your unit for service, please contact Crown Technical Support to verify the need for servicing. This unit has very sophisticated circuitry which should only be serviced by a fully trained technician. This is one reason why each unit bears the following label: CAUTION: To prevent electric shock, do not remove covers. No user serviceable parts inside. Refer servicing to a qualified technician.
