Input routing is configured using the dip switches on the back of the amplifier. See Section 11 Input Routing
for information on configuring switches.
4.7 Connect to AC Mains
Connect your amplifier to the 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, 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.
Amplifiers don’t create energy. The AC mains voltage and current must be sufficient to deliver the power you expect. If the AC line voltage varies out of an acceptable range, the amplifier’s power supply turns off and the blue Power LED flashes. The amplifier will turn back on when the AC line voltage returns to safe operating levels.
Figure 4.7.1 provides voltage limits for all amplifier AC voltage configurations. Also, the amplifier must be run within the specified mains frequency requirements (indicated on the amplifier’s back panel label). If you are unsure of the output voltage of your AC mains, please consult your electrician.

4.8 Startup Procedure
Use the following procedure when first turning on your amplifier:
1. Turn down the level of your audio source.
2. Turn down the level controls of the amplifier (see Section 7.6).
3. Turn on the “Power” switch. The Power indicator should glow.
4. Turn up the level of your audio source to an optimum level.
5. Turn up the Level controls on the amplifier until the desired loudness or power level is achieved.
If you ever need to make any wiring or installation
changes, don’t forget to turn off the amplifier and discon nect the power cord.
For help with determining your system’s optimum gain structure (signal levels) please refer to the Crown Ampli fier Application Guide, available online at www.crownaudio.com.
5 Precautions
Your amplifier is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:
1. Before use, your amplifier first must be configured for proper operation, including input and output wiring hookup. Improper wiring can result in serious operat ing difficulties. For information on wiring and config uration, please consult the Setup section of this manual or, for advanced setup techniques, consult Crown’s Amplifier Application Guide available online at www.crownaudio.com.
2. Use care when making connections, selecting signal sources and controlling the output level. The load you save may be your own!
3. Do not short the ground lead of an output cable to the input signal ground. This may form a ground loop and cause oscillations.
4. Never connect the output to a power supply, battery or power main. Electrical shock may result.
5. Tampering with the circuitry, or making unauthorized circuit changes may be hazardous and invalidates all agency listings.
6. Do not operate the amplifier with the red Clip LEDs constantly flashing.
7. Do not overdrive the mixer, which will cause clipped signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.
8. Do not operate the amplifier with less than the rated load impedance. Due to the amplifier’s output protec tion, such a configuration may result in premature clipping and speaker damage.
9. Output of amplifier cannot be bridged or multiple channels cannot be connected together.
Remember: Crown is not liable for damage that results from overdriving other system components.
Note: ComTech DriveCore amplifiers can NOT be bridged.

8 Amp Configuration 9 Operating Modes
8.1 70Hz HPF (High Pass Filter)
On the back panel, one 2-position high-pass filter switch will only allow signals above 70Hz to be amplified. This is to prevent transformer saturation. The HPF, when turned on, is activated for all channels. The filter is a 2nd order 12 dB/occ t filter.
8.2 Limiter
The limiter reduces amplifier gain to allow over drive without harsh clipping at output.
When Amp Configuration Switch #5 is set to on (pushed up), the amplifier will utilize the limiter feature.
DriveCore Amplifiers can work in a variety of power modes.
9.1 Normal
The amplifier automaticaly operates full output power.
9.2 Green Power
Green mode utilizes Crown’s adaptive rail technology for higher efficiency or power on demand. When Amp Configuration DIP switch #4 is set to on, the amplifier will operate in green mode.
For low input signal levels (less than –40dBu) the amplifier will operate with minimum power.
The amplifier will increase to full power if either of the following occurs:
1 - The input signal goes above -40dBu 2 - There is a single clip event from any of the channels Likewise, if the amplifier is operating with full power,
the amplifier will decrease the operating rails to minimum power if the input signal drops below -40dBu.
Through the use of Green Power, the efficiency of the amplifier dramatically increases for lower audio signal reproduction. The adaptive rail technology used in the CT amplifiers can increase the efficiency of the amplifier by up to 10% with low signal levels.

In deep sleep mode, the amp consumes less than 1 watt of power. It is activated via the AUX port with a ground closure.
To bring the amplifier out of deep sleep, remove the ground closure via the AUX port.
10.2 Amp Status
The Amplifier Status is designed to work with life safety or supervisory monitoring and control systems, where notification of an amplifier fault is necessary. The Amplifier Status is producing a signal (Heartbeat or tone) when the amplifier is operating within standard working parameters. If the amplifier enters a fault or thermal condition, the Amplifier Status signal will terminate. This feature in the ComTech amplifier is always on. The Amplifier
Status is located on the Auxiliary Port, opposite the DEEP SLEEP function. The configuration of the Amp
Status signal is possible through DIP Switch #3:
ON – the microcontroller will send a 1 Hz
pulse to the “AMP STATUS” AUX port line
OFF – the microcontroller will send a logic high level to the “AMP STATUS” AUX port line
The voltage output of the AuxPort is 5VDC at 50 milliamps. This TTL or similar signal can then be connected to an interface to indicate the status to a supervisory control system.
Amp status can be used in a variety of life safety applications, such as EN54, IEC60849 among others.
This amplifier can route a single channel to the next numbered channel.
In CT 475 and CT 4150, DIP switches 6-9 are non-functional.
When a DIP switch is set to “on” for a specific channel, it sends the signal to its own output AND becomes the input for the next numbered channel, overriding the wired input for that channel.

13 Advanced Features
13.1 Protection Systems
Your Crown amplifier provides extensive protection and diagnostic capabilities, including thermal level control, fault indicators, high-pass filtering, DC protect, AC under/over voltage protection, inrush limiting, and a convection-cooled chassis.
13.1.1 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 is reduced.
13.1.2 Fault
The amplifier will enter a Fault state if the amplifier senses an unsafe condition. This protection is for both internal and external faults. It is critical to check all wiring to and from the amplifier to ensure the fault is not caused by external conditions. Once wiring has been verified to be correct, and the fault condition persists, see Section 17 Service for Servicing information.
13.1.3 High-Pass Filters
HPF’s are traditionally used in Hi-Z applications. The Com-Tech DriveCore is a low Z amplifier but can be used in conjunction with the XFMR 4/8 transformer box for Hi-Z applications. If the amplifier is to be used in a Hi-Z application, then it is very important to use the HPF to prevent transformer saturation.
13.1.4 AC Under/Over Voltage Protection
If the AC line voltage drops below 25% or rises above 15% of the nominal operating voltage of the amplifier, the amplifier’s power supply turns off and the blue Power LED flashes. The ampli fier will turn back on when the AC line voltage returns to safe operating levels (within ±10%).
13.1.5 Circuit Breaker
A circuit breaker located near the IEC power inlet protects the amplifier from excessive AC current draw.
13.1.6 Convection-cooled Chassis
The DriveCore amplifiers require no fans for cooling, providing quiet operation and optimum efficiency.
13.1.7 Auto-Standby
If amplifier does not see input signals for a period of 30 minutes, the amplifier will go into standby mode. The amplifier will come out of standby mode once an input signal is present. This feature is activated via DIP switch #2 on the back of the amplifier. The amplifier will be configured with Auto-Standby turn-on from the factory. When the amplifier is in Standby, the Ready Indicator on the front panel Display will flash.
13.2 Features
13.2.1 Switching Power Supply
Crown’s Switching Power Supply minimizes the amplifier’s weight. Typical non-switching power supplies require large, heavy transformers in order to produce the required power at the output stage. These transformers must be large to operate at 50 to 60 Hz (standard AC supplied by the power company).
By contrast, switching power supplies can operate with a much smaller (and lighter) transformer because they first convert the AC up to a much higher frequency, thereby reducing waste. The power supply is voltage-specific, allowing use in regions using 100V or 240V.
13.2.2 Power Mode
Deep sleep and green mode allow the amplifier to operate at all times with the lowest possible power level.
13.2.3 Adaptive Rail Technology (ART)
Crown has developed a voltage rail technology that delivers power on demand. ART is at the center of CT DriveCore’s Green mode that provides up to an additional 10% of efficiency. Through ART, the CT DriveCore is always operating at maximum efficiency.
13.2.4 DriveCore Power Stage
Crown has worked with Texas Instruments to develop an audio amplifier on a micro-chip. The result is DriveCore chipset that introduces audiophile quality for an installation amp:
-Greater than 90% Efficiency
-118dB Signal to Noise
-THD less than .05% in midband frequencies
14 Accessories
14.1 XFMR 4/8
The ComTech DriveCore amplifier is only capable of low Z applications. It is necessary to use an outboard transformer for Hi-Z applications. Crown highly recommends the use of the XFMR 4/8 transformer box. This transformer box is designed to mate with the top of the ComTech DriveCore Amplifiers. See XFMR data sheet for wiring diagram.
14.2 Rack Support Ears
The ComTech DriveCore amplifier requires front and back rack support for proper mounting. These have been provided with the amplifier.
