4 Setup

4.1 Unpack Your Amplifier

Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transporter company immediately. Only you can initiate a claim for shipping damage. Crown will be happy to help as needed. Save the shipping carton as evidence of damage for the shopper's inspection.

We also recommend that you save all packing materials so you will have them if you ever need to transport the unit. Never ship the unit without the factory pack.

YOU WILL NEED (not supplied):

• Input wiring cables
  Output wiring cables
• Flathead screwdriver

Rack for mounting amplifier (or a slab surface for stocking)

WARNING: Before you start to set up your amplifier, make sure you read and observe the Important Safety Instructions found at the beginning of this manual.

4.2 Install Your Amplifier

CAUTION: Before you begin, make sure your amplifier is disconnected from the power source and that all level controls (see section 7.6) are set to 0.

The amplifier is 1.75^ ball by 15.19^ deep and 19^ wide (see figure 4.2.1).

Mount the unit in a standard 19-inch (48.3-cm) equipment rack (EIA RS-310B). You can also place a single amp on a solid, stable surface or stack multiple amps.

NOTE: When transporting, amplifiers should be supported at both front and back.

4.3 Ensure Proper Cooling

When using an equipment rack, mount units directly on top of each other. Close any open spaces in the rack with blank panels. DO NOT block front, top or side air vents.

The side walls of the rack should be a minimum of two inches (5.1 cm) away from the amplifier sides, and the back of the rack should be a minimum of four inches (10.2 cm) from the amplifier back panel. While the amplifier is convectioned closed and does not require a fan, it is critical that the air vents are not covered.

4.4 Choose Input Wire and 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 but unbalanced line may also be used. For more Information, refer to the Crown Amplifier Application Guide, available online at www.crownauditor.com.

Use 3-pin Phoenix-type cable ends at the amp input connectors.

Figure 4.4.1 shows connector pin assignments for balanced wiring and figure 4.4.2 shows connector pin assignments for unbalanced wiring

NOTE: Custom wiring should only be performed by qualified personnel. Class 2 wiring is required.

BALANCED LINE

UNBALANCED LINE
Figure 4.4.2

4.5 Choose Output Wire and Connectors

Crown recommends using professionally constructed, high quality, bio-conductor, heavy gauge spoke wire and connectors Use 2-pin Phoenix-type connectors (Included with the amp).

Suggested below are guidelines to select the appropriate size of wire based on the distance from amplifier to speaker. Check with local code as this may vary.

Distance Wire Size

up to 25 (1.6m) 16M AVG 20-40L 7.9-12m 24M AVG

CAUTION: Never use shielded cable for output wiring.

CAUTION: Never connect the speaker return to the chassis of the amplifier, or damage to the amplifier may result.

CAUTION: Output of amplifier channels cannot be bridged. This may damage the amplifier.

4 Setup

4.6 Wire Your System

Before you are your system, you must be familiar with the capabilities of the input routing.

The DriveCore amplifier can be configured in two ways:

1. The input for a channel goes out the same channel. This option is the standard configuration.

Figure 4.6.1 Four channels with no input routing

Figure 4.6.2 Eight channels with no input routing

1. The input for a channel can be routed to the next channel, overriding the wired input signal for that channel. This method simplifies input wiring and minimizes use of y-cables.

Figure 4.6.3 Two channel to four channel routing

Figure 4.6.4 One channel to four channel routing

Figure 4.6.5 Four channel to eight channel routing

Input routing is configured using the clip switches on the back of the amplifier. See Section 11 Input Routing for information on configuring switches.

Note: ComTech DriveCore amplifiers can NOT be bridged.

4.7 Connect to AC Mains

Connect your amplifier to the AC mains power source (power outlet) with the supplied AC power cord set. First, connect the IFC end of the cordset to the IFC 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 rms frequency requirements (indicated on the amplifier's back panel layout). 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 disconn net the power cord.

For help with determining your system's optimum gain structure (signal levels) please refer to the Crown Amplifier Application Guide, available online at www.crownaudic.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 operating difficulties. For information on wiring and configuration, 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 load 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.

1. Tampering with the circuitry, or making unauthorized circuit changes may be hazardous and invalidates all agency listings.
2. Do not operate the amplifier with the red Clip LEDs constantly flashing.
3. Do not overdrive the mixer, which will cause clipping signal to be sent to the amplifier. Such signals will be reproduced with extreme accuracy and loudspeaker damage may result.
4. Do not operate the amplifier with less than the rated load impedance. Due to the amplifier's output protection, such a configuration may result in premature clipping and speaker damage.
5. 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.

8.1 70Hz HPF (High Pass Filter)

On the back panel, one 2-position high-pass filter switch will only allow signals above 70kHz to be amplified. This is to prevent transformer saturation. The HFW, when turned on, is activated for all channels. The filter is a 2nd order 12 dB/osc 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 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 automatically 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 -40dB ) 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 tail technology used in the CT amplifiers can increase the efficiency of the amplifier by up to 10% with low signal levels.

9.3 Deep Sleep

See Section 10.1

Figure 9.2.1 How Green Power DIP switches work

10 Auxiliary Port 11 Input Routing

10.1 Deep Sleep

In sleep sleep mode, the arms consume 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 CamToch 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 SVDG at 50 milliamps. This T1L 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 IEC60649 among others.

This amplifier can route a single channel to the next numbered channel.

In CT 475 and CT 4150, DIP switches 8-9 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 correction-cooler chassis.

13.1.1 Thermal Indicator

If the amplifier becomes too hot for safe operation, the channel trial 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 Cam-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 amplifier 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 IFC 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 AG 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

Dopso 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 DriverCore chipset that introduces audiophile quality for an installation amp:

Greator than 90% Effciency

11B Signal to Noise

-THD less than .05% in midband

frequencies

14 Accessories

14.1XFMR 4/8

The CornTech 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 make with the loop of the CornTech DriveCore Amplifiers. See XFMR data sheet for writing 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.
