Turn down the level of your audio source.

2.

Turn down the level controls of the amplifier.

3.

Turn on the “Enable” switch. The Enable 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.

6.

Turn down the level of your audio source to its normal range.

If you ever need to make any wiring or installation changes, don’t forget to 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.

4 Operation

4.1 Precautions

Your Macro-Tech Series 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 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 Signal/

IOC LEDs constantly flashing.

7.

Do not overdrive the mixer, which will cause a clipped signal to be sent to the amplifier.

Such signals will be reproduced with extreme accuracy, and loudspeaker damage may result.

8.

Never 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

5 Advanced Features and Options

NOTE: For detailed information about these

Crown amplifier features, please consult the

Crown Amplifier Application Guide, available on the Crown website at www.crownaudio.com

5.1 Protection Systems

Your Crown amplifier provides extensive protection and diagnostic capabilities, including ODEP and IOC.

5.1.1 Output Device Emulation Protection

(ODEP)

Crown invented ODEP to solve two long standing problems in amplifier design: To prevent amplifier shutdown during demanding operation and to increase the efficiency of output circuitry.

To do this, Crown established a rigorous program to measure the safe operating area (SOA) of each output transistor before installing it in an amplifier. Crown also designed intelligent circuitry to simulate the instantaneous operating conditions of those output transistors. Its name describes what it does: Output Device Emulation Protection or ODEP. It not only simulates the operation of the output transistors but it also compares their operation to their known SOA. If ODEP sees that more power is about to be asked of the output devices than they are capable of delivering under the present conditions, ODEP immediately limits the drive level until it falls within the SOA.

Limiting is proportional and kept to an absolute minimum—only what is required to prevent the possibility of output transistor damage.

This level of protection enables Crown to increase output transistor utilization while greatly increasing amplifier reliability.

Finally, this onboard intelligence is monitored in two ways.

First, the front panel ODEP indicators show whether the amplifier is functioning correctly or if ODEP is limiting the drive level. Second, ODEP data is fed to the PIP connector at the back of the amplifier so advanced PIP modules like the IQ-PIP-USP2 can use it to make decisions and control the amplifier.

With ODEP you get the maximum power with the maximum protection—the show goes on!


5.1.2 IOC (Input Output Comparator)

The IOC circuit compares the output signal of the amplifier with the input signal. If there is any difference other than gain, then it is considered distortion and the indicator comes on. The LED indicator will come on whenever there is distortion of 0.05% or more. An IOC condition may also be sensed by an IQ PIP module installed in PIP-compatible amplifiers.

IOC is designed to report any form of distortion. IOC not only checks the waveform for distortion, but also reports input overload and even a protective action that mutes or shuts down an amplifier. With all of these features, IOC monitors the entire amplifier. When the IOC indicator is off the amplifier is definitely operational and undistorted. IOC provides an on-line proof of performance.

5.2 Circuit Designs

5.2.1 Grounded Bridge

Grounded Bridge is the name of Crown's unique fourquadrant amplifier topology. The Grounded Bridge topology takes full advantage of the power supplies delivering peak-to-peak voltages to the load that are twice the voltage seen by the output devices and twice the voltage generated by the power supplies.

The power supply bridge rectifier is not ground referenced, and the transformer secondary is not center-tapped. This allows the power supply to deliver +VCC and -VCC from the same bridge rectifier and filter as a total difference in potential regardless of their voltages with respect to ground.

Composite output devices are arranged to function as gigantic NPN and PNP devices. Each output stage has two composite NPN and two composite PNP devices. The devices connected to the load are referred to as “high-side

NPN and PNP” and the devices connected to ground are referred to as “low-side NPN and PNP.” Positive current is delivered to the load by increasing conductance simultaneously in the high-side NPN and low-side PNP stage, while decreasing conductance of the high-side PNP and low-side NPN in synchrony.

Crown's Grounded Bridge design delivers large voltage swings without stressing output transistors. The results are higher efficiency, lower distortion and superior reliablility.

5.2.2 Variable Impedance (VZ)

VZ is the name of Crown's patented articulated power supply technology. This innovative technology permits us to pack large amounts of power into a compact package while achieving ultra-low distortion and without generating excessive heat.

An amplifier power supply must be large enough to handle both the maximum voltage and maximum current necesary for the amplifier to drive its rated power into a specified load. In order to meet this requirement, most conventional supplies are heavy, large, and produce lots of heat. In contrast, the VZ supply gets more current AND voltage out of a smaller, lighter, and more efficient package by dynamically adapting to both signal and load requirements in real-time. This provides the best power match to the widest range of loads.

The VZ supply is divided into two segments. When the output stage requires high-voltage, the segments are arranged in series to deliver twice the voltage of a single segment. When the output stage requires high-current, the segments are arranged in parallel to deliver twice the current of a single segment. Sensing circuitry "watches" the voltage of the signal to determine when to switch VZ modes. The switching circuitry is designed to prevent audible switching distortion to yield the highest possible dynamic transfer function—you hear only the music and not the amplifier.

With VZ, you get not only maximum power and safety, but you also get the best power matching to your load.

The VZ (Variable Impedance) mode causes the power supplies to automatically shift between high-current and low-current modes of operation as operating conditions change. Normally, the power supplies operate in the highcurrent (low-impedance) mode for maximum thermal efficiency. When voltage demand reaches highs levels, the supplies quickly shift into high-voltage (high-impedance) mode. Because voltage and current requirements vary with the output level and frequency content of the source signals, the power supplies are designed to be able to continually switch between the two modes as needed with no degradation to the audio signal.

The VZ Mode switches allow you to control the operation of the VZ power supply for each channel.

The VZ mode switches are located inside the amplifier behind the top dust filter on the front panel. To access these switches, remove the top filter element. Always

turn the power off before changing one of these

switches. Each switch has four settings (from left to right): VZ-ODEP, Lock Low, VZ and VZ. Note: The third and fourth positions are identical. The amplifier is shipped from the factory with the switches set to "VZ-ODEP”.

The VZ (Variable Impedance) mode causes the power supplies to automatically shift between high-current and low-current modes of operation as operating conditions change. Normally, the power supplies operate in the highcurrent (low-impedance) mode for maximum thermal efficiency. When voltage demand reaches highs levels, the supplies quickly shift into high-voltage (high-impedance) mode. Because voltage and current requirements vary with the output level and frequency content of the source signals, the power supplies are designed to be able to continually switch between the two modes as needed with no degradation to the audio signal.

The VZ-ODEP mode is very similar to VZ mode. The only difference is that the power supplies are forced into high-current mode when ODEP is close to activating its limiting circuitry. This reduces excessive stress on the output transistors, and effectively increases the thermal performance of the amplifier.

Note: When ODEP limiting begins, the IOC circuitry will see that the input waveform does not match the output waveform, and an error signal is generated. If the compressors are on, they will see the error signal and compress the input signal to correct the problem. When this happens, there is no audible signal degradation.

Compression is subtle, and not noticeable unless the system is driven to extremely high levels.

The Lock Low mode locks the power supplies into the high-current mode for low-impedance loads. This may be desirable when driving high-frequency transducers that must be protected from too much voltage, or when driving loads with very low impedances.

5.2.3 ILoad/ILimit

The ILoad/ILimit feature is designed to help you get the maximum power out of your amplifier. In the real world, loudspeaker impedance varies with frequency, and loudspeaker impedance ratings are only approximations. Without ILoad/ILimit, you have to do some lengthy calculations to approximate the maximum number of loudspeakers you can drive with the amplifier—and this does not allow for a

4 ohm loudspeaker whose impedance drops below 2 ohms at 80 Hz.

This is why your amplifier has ILoad/ILimit. The ILoad function turns a channel’s ILoad/ILimit indicator green when it senses current is flowing to the load. The ILimit function turns the indicator red when it reaches maximum current output. This makes it possible to connect real loudspeakers and conduct realistic tests to find the maximum number of loudspeakers that should be connected.

To do a test like this, you can operate under worst-case conditions and continue to connect additional loudspeakers in parallel with each output until the ILoad/ILimit indicator turns red. The optimum load is achieved before the

ILoad/ILimit indicator turns red, so disconnecting the last added loudspeaker gives you an optimized load.

Figure 5.1 Channel 1 VZ Mode Switch (Behind Filter)

5.2.4 Loudspeaker Offset Integration

Loudspeaker Offset Integration (LOI) circuits use double integrating filters in the amplifier’s feedback circuitry to protect loudspeakers in several different ways. First, they center asymmetrical audio waveforms that cause off-center woofer cone movement. Off-center cone movement increases loudspeaker heating and distortion while reducing the loudspeaker’s power handling ability. Second, LOI filters unwanted DC and subsonic frequencies using a third-order Butterworth filter with a 35 Hz corner frequency. Third, LOI filters unwanted ultrasonic frequencies (RF) that can cause tweeter burnout using a secondorder Bessel filter with a 50 kHz corner frequency.

IMPORTANT: The Loudspeaker Offset Integration circuitry does NOT protect loudspeakers from large transient voltages or excessive power

levels for prolonged periods of time. Crown is not liable for damage or personal injury that results from overdriving loudspeakers or other system components. For information on techniques to protect loudspeakers, refer to the Crown Amplifier Application Guide, available online at www.crownaudio.com.

5.3 Options

5.3.1 PIP™ Modules

Versatile PIP (Programmable Input Processor) modules provide flexible expansion features that can be added to customize the amplifier. PIP modules plug into the connector inside the back panel of the amplifier. PIP modules are available with features ranging from errordriven compressor/limiters to IQ control. Your amplifier is a PIP2 amplifier, which means it can take advantage of the many advanced features found in PIP2 modules, as well as all standard PIP modules. Visit the Crown website at www.crownaudio.com, or contact Crown Customer

Service, for descriptions of available PIP and PIP2 modules.

6 Troubleshooting

CONDITION: Normal operation.

POSSIBLE REASON:

• This is normal operation for your amp.

• The amp is set for Parallel Mono mode.

CONDITION: Distorted sound.

POSSIBLE REASON:

• Input signal level is too high. Turn down your amplifier level controls. NOTE: Your amplifier should never be operated at a level which causes the Signal/IOC LEDs to constantly indicate an IOC condition.

• ODEP limiting has been activated. Take appropriate measures to keep the ampifier out of ODEP limiting (see Section 5.1.1 for more information about ODEP).

• Output current is being limited because the load impedance of the channel is too low, or the output is shorted.

Key


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 low-voltage power supply fuse has blown. Return amp to Crown or an authorized Crown Service Center for servicing.

CONDITION: No sound.

POSSIBLE REASON:

• The amplifier has just been turned on and is still in the 4-second turn-on delay.

• The amplifier is being held in Standby Mode by an installed IQ PIP module.

• The amplifier is in drive protection mode.

This can occur with improper source signals like infrasonic square waves or input overloads that excessively clip the input signal.

• No input signal

• Input signal level is very low.

• Level controls are turned down.

8 Service

Crown amplifiers are quality units that rarely require servicing. Before returning your unit for servicing, 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.

8.1 Worldwide Service

Service may be obtained from an authorized service center. (Contact your local Crown/

Amcron representative or our office for a list of authorized service centers.) To obtain service, simply present the bill of sale as proof of purchase along with the defective unit to an authorized service center. They will handle the necessary paperwork and repair.

Remember to transport your unit in the original factory pack.

8.2 US and Canada Service

Service may be obtained in one of two ways: from an authorized service center or from the factory. You may choose either. It is important that you have your copy of the bill of sale as your proof of purchase.

8.2.1 Service at a US or Canada

Service Center

This method usually saves the most time and effort. Simply present your bill of sale along with the defective unit to an authorized service center to obtain service. They will handle the necessary paperwork and repair. Remember to transport the unit in the original factory pack. A list of authorized service centers in your area can be obtained from our Technical Support

Group.

page 22

8.2.2 Factory Service

To obtain factory service, fill out the service information page found in the back of this manual and send it along with your proof of purchase and the defective unit to the Crown factory.

For warranty service, we will pay for ground shipping both ways in the United States. Contact Crown Factory Service or Technical Support to obtain prepaid shipping labels prior to sending the unit. Or, if you prefer, you may prepay the cost of shipping, and Crown will reimburse you. Send copies of the shipping receipts to Crown to receive reimbursement.

Your repaired unit will be returned via UPS ground. Please contact us if other arrangements are required.

8.2.3 Factory Service Shipping

Instructions:

1.

Before sending a Crown product to the factory for service, first call the Crown Service Department for a return authorization

(RA) number.

2.

Be sure to fill out the service information form that follows and enclose it with your shipment, either inside the box or in a packing slip envelope securely attached to the outside of the shipping carton. Do not send the service information form separately.

3.

To ensure the safe transportation of your unit to the factory, ship it in an original factory packing container. If you don’t have the original carton, you may obtain a product service foam-in-place shipping pack from the Crown Factory Service Department at the number listed below. For nonwarranty service, you may also provide your own shipping pack. Minimum recommended requirements for materials are as follows: 275 P.S.I. burst test Double-Wall carton that allows for 2-inch solid Styrofoam on all six sides of unit or 3 inches of plastic bubble wrap on all six sides of unit;


securely seal the package with an adequate carton sealing tape. Do not use light boxes or “peanuts.” Damage caused by poor packing cannot be covered under warranty.

4.

Do not ship the unit in any kind of cabinet

(wood or metal). Ignoring this warning may result in extensive damage to the unit and the cabinet. Accessories are not needed—do not send the product documentation, cables and other hardware.

If you have any questions, please call or write

Crown Factory Service.
