Set-up and System Conguration

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. A male connector is supplied for each input of your model of ampliﬁer. Additional connectors are available from Crown (P/N 5024623).

Figure 3 shows connector pin assignments for balanced wiring and Figure 4 shows connector pin assignments for unbalanced wiring. Note that for bridged operation, only the connectors for oddnumbered channels (1,3,5,7) for each bridged pair need be wired. See Page 9 and 11.

Wire Output Connectors

Crown has designed an output cover that does not need to be removed to connect the output wiring.

Figure 3

Figure 4

Crown recommends using the included spade connectors and two- or four-conductor, heavy gauge speaker wire. You may use terminal forks up to 10 AWG or bare wire for your output connectors (see Figure 5). For best results, Crown recommends Panduit part #PV10-6LF-L or equivalent terminal fork. For bare wire, it is highly recommended that output wiring is tinned. To reduce strain on input and output wiring, Crown recommends the use of horizontal lacer bars. For best results, Crown recommends Middle Atlantic part# LBP-4R90 or equivalent horizontal lacer bar.

To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.

For low-impedance loads, select the appropriate size of wire based on the distance from ampliﬁer to speaker.

Distance Wire Size Up to 25 ft. (7.6m) 16 AWG 26-40 ft. (7.9-12.2m) 14 AWG 41-60 ft. (12.5-18.3m) 12 AWG > 60 ft (18.3m) 10 AWG

CAUTION: Never use shielded cable for output wiring.

Figure 5

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

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

Set-up and System Conguration

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. When multiple loudspeakers are connected to one output for Hi-Z operation, be certain total tapped power is below the rated power output for the channel. For additional information, please consult Crown’s Ampliﬁer Application Guide (available online at www. crownaudio.com).

Note: Illustrations and some text references are for channel pair 1 - 2 only. Connections and settings are identical for channels 3 – 4 on four-channel models and for channels 5 – 6 and 7 – 8 on eight-channel models. Each channel pair may be conﬁgured independently on multichannel models.

Dual Mode Low-Z (8, 4 or 2 Ohm)

Typical input and output wiring, along with Attenuator and Mode DIP Switch settings are shown in Figure 6. Make sure DIP Switches are in the default OFF (down) position.

INPUTS: Connect the input with wiring in place for each channel. If the same signal is to drive both outputs of a channel pair (“mono”), the signal must be split externally and applied to both inputs.

OUTPUTS: Maintain proper polarity (+/–) on output connectors. Connect the Channel 1 speaker’s positive (+) lead to ampliﬁer Channel 1 positive terminal; repeat for negative (–). Repeat Channel 2 wiring as for Channel 1, and for any subsequent channel pairs on multichannel models. Refer to Page 7 for output connector terminal assignments.

DCi Series Power Ampliﬁers

Set-up and System Conguration

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.

Make certain the AC mains voltage and current ratings are sufﬁcient to deliver full power to all ampliﬁers. 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.

DriveCore Install Ampliﬁers utilize a universal power supply. The AC voltage requirements are 100VAC - 240VAC, 50/60Hz (+/-10%). If the voltage exceeds these requirements, then the Power LED will ﬂash and the ampliﬁer will stop passing audio until the voltage is within the requirements.

Startup 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 to INF Page 14.

3. Turn on the “Power” switch. The Power indicator should light.

4. Turn up the level of your audio source to an optimum level. Ensure that at no point in the signal chain is the signal being clipped in any way.

5. Turn up the level controls on the ampliﬁer to the desired loudness or power level.

IMPORTANT: Before making any wiring or installation changes, turn off the ampliﬁer and disconnect 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.crownaudio.com.

Precautions

Your ampliﬁer is protected from internal and external faults, but you should still take the following precautions for optimum performance and safety:

1. Conﬁgure the ampliﬁer 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 Page 7 of this manual. 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 invalidate 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 protection, such a conﬁguration may result in premature clipping and

speaker damage. Remember: Crown is not liable for damage that results from overdriving other system components.

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.

Ampliﬁer Status (switch B)

The Ampliﬁer Status works with life safety or supervisory monitoring and control systems where notiﬁcation of an ampliﬁer fault is necessary. The Ampliﬁer Status produces a signal (“heartbeat”) 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 is always on and available when the ampliﬁer is ready to deliver audio in selected mode through the AMP STATUS line on the AUX port.

The Ampliﬁer Status signal is selectable:

• ON – the microcontroller will send a 2 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 Aux Port is 5VDC at 0.9 milliamps. This TTL or similar signal can then be connected to an interface to indicate the ampliﬁer status to a supervisory control system.

Amp status can be used in a variety of life safety applications

Power Save (switch C)

The Power Save switch enables the Auto-Standby function. In OFF position, the Auto Standby feature is disabled; ampliﬁer power on/off is controlled by the front panel switch or the AUX port ground closure.

In the ON position, Auto Standby is enabled. If the ampliﬁer input does not see signal for 30 minutes, the ampliﬁer will power down to consume less than 1W of power. When -40dBu of input signal is applied, then the ampliﬁer will power up for activation. The power up sequence will take approximately 4 - 5 seconds.

Per Channel Settings

Note: The following text and illustrations refer to one channel pair, channels 1 and 2. Settings and functions are identical for other channels pairs (3/4, 5/6, 7/8) in multichannel models.

Hi-Z

Each channel of the channel pair is individually selectable for Lo-Z or Hi-Z operation. When Hi-Z operation is selected (ON, up) a 35Hz high pass ﬁlter is selected automatically. The ﬁlter can be changed to 70Hz. Contact your local Crown service center for detailed instruction for this change. When a channel pair is conﬁgured for bridged Hi-Z mode, only switches assigned to the odd-numbered channels (1,3,5,7) are active; switches for the even-numbered channels (2,4,6,8) are disabled.

Channel Attenuators

Each channel is supplied with a logrithmic 21-position detented input attenuator. Use a ﬂat-blade screwdriver to set input level. Attenuation is from -95 dB (full counterclockwise) to 0 dB (full clockwise).

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. The ampliﬁer will continue to run in this state until either the temperature is reduced to a safe operating range, or if the temperature continues to rise, the channel will shut off to protect itself above 98 degrees Celsius.

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. If wiring is veriﬁed as correct and the fault condition persists, see Page 29 for servicing information.

Auto Insertion High-Pass Filters

A 35 Hz high-pass ﬁlter is inserted automatically when a channel is selected for Hi-Z operation. The ﬁlter can be changed to a 70Hz high pass ﬁlter. Please contact Crown Service Department for further information.

AC Under/Over Voltage Protection

If the AC line voltage drops below 10% or rises above 10% 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.

Fuse

A fuse (F1) located near the IEC power inlet protects the ampliﬁer from excessive AC current draw. The fuse is ﬁeld replaceable. Replace with same type fuse; LittelFuse 314 Series F20AH 250V. The 8|600 and 4|1250 utilize a resettable breaker instead of a fuse. Please contact Crown Service department for more information.

Fan-cooled Chassis

DCi Series ampliﬁers are cooled by quiet, variable speed fans. The fans will pull air from the front of the ampliﬁer to the rear of the ampliﬁer.

Universal Switching Power Supply

The DCi Series incorporates a new switching power supply designed for extremely high efﬁciency and high output power. The supply includes Power Factor Correction (PFC), a Series Resonant Converter (SRC) and accepts AC supply voltages from 100 V~ to 240 V~. Microprocessor controlled diagnostic and control capabilities both optimize performance, and enhance long-term reliability.

Troubleshooting

DCi Series Power Ampliﬁers

CONDITION: Power indicator is off. Mains indicator is on.

POSSIBLE REASON

• The amplier’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 amplier has lost AC Power.

• The amplier is not plugged in to the power receptacle.

CONDITION: Power indicator is ashing.

POSSIBLE REASON:

• The AC line voltage has dropped below 10% or has risen above 10% of the nomi nal line voltage of the power supply.

• When the Amp is in Sleep Mode as set by

the AUX Port, the amplier will not power

up until the ground closure on the AUX Port is released. When the power button is pushed in this condition, the Power

Indicator will ash for 2 – 3 seconds.

CONDITION: Thermal indicator is on.

POSSIBLE REASON:

• The amplier is becoming too hot for safe operation. Allow amplier to cool. Check for loads less than 2 ohms,

and for excessive input levels. Check for proper ventilation and proper mode-switch set ting.

CONDITION: Fault indicator is ashing.

POSSIBLE REASON:

• There are a number of conditions that

result in the Fault indicator ashing:

temperature above 98C, DC/LF protection is engaged, HF detect, output short circuit detected. These conditions should all be checked and attempted to be resolved before the amp is shipped back for service.

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 amplier 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 dis torted before it reaches the ampliﬁer input. Check gain staging and output levels of the mixer or preamp.

CONDITION: No sound, even though the amp has power. Power

LED is on with out ﬂashing and the amp is receiving an input sig nal. Signal indicator is ﬂashing.

POSSIBLE REASON:

• Speakers not connected.

• Open circuit due to speaker failure.

“Off/Flashing/On” above means that the LED can be off, or ﬂashing, or on.

• Based on the front panel LEDs, determine which channel has a short. Remove the associated input connector to ensure that no voltage will be present on the output. Remove the shorted load (and possibly attached

cables) and have it checked by a qualied

technician. If the shorted condition remains after the load is removed, the unit should be

sent into a qualied service center.

• Ready LED is off. Channel has been set to

Sleep mode via the Aux port or Power Save mode.

Minimum Guaranteed Power (20 Hz - 20 kHz)

DCi Series Power Ampliﬁers

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:

• Amplier is in bridge-mono mode.

SUMMARY OF WARRANTY

Crown International, 1718 West Mishawaka Road, Elkhart, Indiana 46517-4095 U.S.A. warrants to you, the ORIGINAL PURCHASER and ANY SUBSEQUENT OWNER of each NEW Crown product, for a period of three (3) years from the date of purchase by the original purchaser (the “warranty period”) that the new Crown product is free of defects in materials and workmanship. We further warrant the new Crown product regardless of the reason for failure, except as excluded in this Warranty.

*Warranty is only valid within the United States of America. For information on Warranty outside of the U.S.A., please contact your local distributor.

ITEMS EXCLUDED FROM THIS CROWN WARRANTY

This Crown Warranty is in effect only for failure of a new Crown product which occurred within the Warranty Period. It does not cover any product which has been damaged because of any intentional misuse, accident, negligence, or loss which is covered under any of your insurance contracts. This Crown Warranty also does not extend to the new Crown product if the serial number has been defaced, altered, or removed.

WHAT THE WARRANTOR WILL DO

We will remedy any defect, regardless of the reason for failure (except as excluded), by repair, replacement, or refund. We may not elect refund unless you agree, or unless we are unable to provide replacement, and repair is not practical or cannot be timely made. If a refund is elected, then you must make the defective or malfunctioning product available to us free and clear of all liens or other encumbrances. The refund will be equal to the actual purchase price, not including interest, insurance, closing costs, and other ﬁnance charges less a reasonable depreciation on the product from the date of original purchase. Warranty work can only be performed at our authorized service centers or at the factory. Warranty work for some products can only be performed at our factory. We will remedy the defect and ship the product from the service center or our factory within a reasonable time after receipt of the defective product at our authorized service center or our factory. All expenses in remedying the defect, including surface shipping costs in the United States, will be borne by us. (You must bear the expense of shipping the product between any foreign country and the port of entry in the United States including the return shipment, and all taxes, duties, and other customs fees for such foreign shipments.)

HOW TO OBTAIN WARRANTY SERVICE

You must notify us of your need for warranty service within the warranty period. All components must be shipped in a factory pack, which, if needed, may be obtained from us free of charge. Corrective action will be taken within a reasonable time of the date of receipt of the defective product by us or our authorized service center. If the repairs made by us or our authorized service center are not satisfactory, notify us or our authorized service center immediately.
