1 Welcome

Building on the foundation of the Com-Tech® Series, the Crown

CTs Series offers new flexibility and value for installed sound. The ComTech Series was the first to offer independent selection of high- and low-impedance operation for a specific channel, and CTs Series amplifiers continue that tradition, with power levels and features carefully chosen to perfectly integrate into fixed install design requirements.

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.

In addition, CTs Series amplifiers include a number of features which require some explanation before they can be used to their maximum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

• Switching Power Supply for reduced

weight.

• High power-density, with all two-channel

models in a 2U chassis.

• Direct constant-voltage (70V/140V) or low-impedance (2/4/8 ohm) operation. No switch required.

• Input sensitivity is independently selectable for each channel. Choose low-impedance (4/8 ohm), constant-voltage (70V/ 100V/140V/200V), or 26 dB.

• TLC protection circuitry protects the amplifier from long-term excessive heat by subtly and dynamically reducing the gain only when necessary.

• JTS circuitry (CTs 600/1200 only) quickly protects BJT output transistors from unsafe operating conditions without shutting the channel down. (Not applicable to BCA amplifiers as they are inherently protected.)

• PIP2™ (Programmable Input Processor) connector accepts accessory modules that tailor the amplifier to suit specific applications.

• Removable terminal block input connectors, with “Y” Input Switch in the standard PIP2-BBY module.

(Continued on next page)

CTs Power Amplifiers

Operation Manual

• Legendary Crown class I (BCA®) and class AB+B (Multi-Mode

) output topologies offer the best in amplifier reliability. CTs 600/1200 use Class AB+B; CTs 2000/ 3000 use Class I.

• Class I is the lowest distortion, lowest noise, and highest performing topology available among switch-mode amplifiers.

• Continuously-variable fans optimize cooling efficiency.

• Three Year, No-Fault, Fully-Transferable Warranty completely protects your investment and guarantees its specifications.

2 How to Use This Manual

This manual provides you with the necessary information to safely and correctly setup and operate your amplifier. It does not cover every aspect of installation, setup or operation that might occur under every condition. For additional information, please consult Crown’s Amplifier Application Guide (available online at www.crownaudio.com), Crown Tech Support, your system installer or retailer.

We strongly recommend you read all instructions, warnings and cautions contained in this manual. Also, for your protection, please send in your warranty registration card today. And save your bill of sale—it’s your official proof of purchase.

Features (continued from page 8)

• Switchable high-pass filter for each channel provides low-frequency roll off to eliminate step down transformer saturation when used in distributed systems.

• Comprehensive array of indicators including Power, Data, and Bridge; along with Ready, Signal, Clip, Thermal and Fault for each channel, provide accurate diagnostics.

• Blue Power Indicator flashes if the amplifier shuts off due to an under/over-voltage condition on the AC mains.

• Advanced protection circuitry guards against: shorted outputs, DC, mismatched loads, general overheating, under-/overvoltage, high-frequency overloads and internal faults.

3.1 Unpack Your Amplifier

Please unpack and inspect your amplifier for any damage that may have occurred during transit. If damage is found, notify the transportation 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 shipper’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 Rack for mounting amplifier (or a stable surface

for stacking)

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.

3.2 Install Your Amplifier

CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with power switch in the “off” position and all level controls turned completely down (counterclockwise).

Use a standard 19-inch (48.3 cm) equipment rack. See Figure 3.1 for amplifier dimensions.

You may also stack amps without using a cabinet.

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

3.3 Ensure Proper Cooling

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

Figure 3.2 illustrates standard amplifier airflow.

3.4 Choose Input Wire and Connectors

Figure 3.3 shows connector pin assignments for balanced wiring, and Figure 3.4 shows connector pin assignments for unbalanced wiring.

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. Loosen screws inside top and bottom holes of cover (see Figure 3.6).

2. Slide cover to left or right, then pull it off away from the amplifier.

3. Tighten screws. Crown recommends using professionally con-

structed, high-quality, two- or four-conductor, heavy gauge speaker wire and connectors. You may use terminal forks up to 10 AWG or bare wire for your output connectors (see Figure 3.5). To prevent the possibility of short-circuits, wrap or otherwise insulate exposed loudspeaker cable connectors. For best results, Crown recommends Panduit part #PV10-10LF-L or equivalent terminal fork. Screw spacing is shown in Figure

3.5. Using the guidelines below, select the appropri-

ate size of wire based on the distance from amplifier to speaker (low-impedance loads only).

CAUTION: Never use shielded cable for output wiring.

Replace output cover after output wiring is complete.

Operation Manual

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.

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. Check the amplifier’s back-panel label which specifies the required AC mains voltage and frequency. The AC mains voltage must be no more than 15% above the required voltage, and no less than 25% below the required voltage. The AC mains frequency must be within the required frequency range. If you are unsure of the output voltage of your AC mains, please consult your electrician.

3.8 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.

3. Turn on the “Power” switch. The Power indicator should glow. Wait for the “Ready” LED to illuminate.

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. Verify that the Signal LED is flashing.

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 Ampli- fier Application Guide, available online at www.crownaudio.com.

4 Operation

4.1 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 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 circuitr y, 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 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.

Red LED, one per channel, flashes when the amplifier output channel has stopped operating. Usually this means that the amplifier must be serviced.

B. Thermal Indicator

Red LED, one per channel, illuminates when the channel has shut down, or is very near shutting down, due to thermal stress or overload.

C. Ready Indicator

Green LED, one per channel, illuminates when the channel is initialized and ready to produce audio output. Indicator is off when the channel is set to standby mode via the System Architect or IQ Control Software packages.

Signal Indicators

Three green LEDS per channel indicate the amplifier’s input and output signal levels. From bottom to top the LEDs are:

D. Signal: input signal is above –40 dBu. E. –20 dB: amplifier output is within 20 dB of

clipping.

F. –10 dB: amplifier output is within 10 dB of

clipping.

G. Clip Indicator

Red LED, one per channel, illuminates when the channel’s output signal reaches the onset of audible clipping. The Clip Indicator also will illuminate during Thermal Level Control (TLC) limiting or when the input compressor/limiter is protecting the amplifier from input overload.

H. Cooling Vents

Front-to-rear forced airflow.

I. Power Indicator

Blue LED indicates AC power has been applied and is within the safe operating range of the power supply. The LED will flash when the AC line voltage is approximately 15% above or 25% below the nominal rated value.

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 thermal level control, fault indicators, highpass filtering, DC protect, AC under/over voltage protection, inrush limiting, and variablespeed fans.

5.1.1 Thermal Level Control (TLC)

If the amplifier becomes too hot for safe operation, the light will shine brightly a nd TLC will engage the input compressor. By compressing the input, the amplifier will not generate as much heat and will have a chance to cool down. The degree of compression is proportional to the amount of overheating. This feature allows the show to go on, rather than having the amplifier shut down.

5.1.2 Junction Temperature Simulation (JTS) (CTs 600/1200 only)

JTS circuitry simulates the operation of the amplifier’s output transistors, and compares it against the transistors known Safe Operation Area (SOA). If JTS sees that more power is about to be asked of the output devices than they are capable of delivering under the present conditions, JTS immediately limits the drive level until it falls within the SOA. Limiting is proportional and kept to an absolute minimumonly what is required to prevent the possibility of output transistor damage.

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

5.1.3 Fault

The amplifier will light the Fault LED if the amplifier output stage stops operating. If this happens, see Section 8 for servicing information.

5.1.4 High-Pass Filters

Very low frequency signals contain no useful musical energy, waste valuable amplifier power and headroom, and can be damaging to your speakers. Your Crown amplifier provides highpass filters to remove these signals from each channel’s output.

On the back panel are two 3-position 3rd-order high-pass filter switches (one per channel) with selections of Off, 35Hz and 70 Hz.

5.1.5 Low-Pass Filters

Gaussian-approximation ultrasonic filters prevent ultrasonic feedback and HF burnout in drivers. This type of filter preserves transient response better than a Butterworth filter.

5.1.6 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 +15% /

-25%).

5.1.7 Circuit Breaker

A circuit breaker located near the IEC power inlet protects the amplifier from excessive AC current draw.

5.1.8 DC Output Servo

The output servo circuit protects your drivers by eliminating DC offset, even in the presence of very large asymmetrical signals.

5.1.9 Inrush Limiting

A soft-start circuit in the power supply minimizes the amplifier’s current draw during power-on.

5.1.10 Variable-speed Fans

Two continuously variable speed fans direct the airflow through the amplifier for cooling.

5.2 Advanced Features

5.2.1 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 120V or 240V.

5.2.2 Input Compressor

Prevent input/output overload.

5.2.3 Sleep Circuit

Lowers standby power consumption by shutting down the high-voltage supplies during idle periods.

NOTE: By default, the sleep circuit is not active on the CTs 600/1200, but may be activated as a service option.

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). The Specifications chapter lists the input sensitivity for the 26 dB gain setting.

5.3 Options

T-170V: See Figure 5.3. This is an autoformer that allows 100V output from the CTs 600/1200, and allows other amplifiers without direct constant voltage output to be easily integrated into distributed systems.

TP-170V: See Figure 5.4. This is a rack-mountable panel with four autoformers as described above.

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 error-driven compressor/limiters to crossovers to remote control and monitoring via IQwic™ or System Architect software. Your amplifier is a PIP2 amplifier, which means it can take advantage of the many advanced features found in PIP2 modules. The CTs Series 2-channel models do not accept earlier PIP modules.

Visit the Crown website at www.crownaudio.com, or contact Crown Customer Service, for descriptions of available PIP and PIP2 modules.

3.1 Unpack Your Amplifier

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 Rack for mounting amplifier (or a stable surface

for stacking)

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.

3.2 Install Your Amplifier

CAUTION: Before you begin, make sure your amplifier is disconnected from the power source, with the power switch in the “off” position and all level controls turned completely down (counterclockwise).

Use a standard 19-inch (48.3-cm) equipment rack (EIA RS-310B). See Figure 3.1 for amplifier dimensions.

You may also stack amps without using a cabinet.

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

3.3 Ensure Proper Cooling

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

Figure 3.2 illustrates standard amplifier airflow.

3.5 Choose Output Wire and Connectors

Crown recommends using professionally constructed, highquality, two- or four-conductor, heavy gauge speaker wire and connectors. You may use terminal forks or bare wire for your output connectors (see Figure 3.5). CTs amplifier terminal strips accept up to 10 AWG terminal forks which fit over a #8 screw. For best results, Crown recommends Panduit part #PV10-10LF-L or equivalent terminal fork. Screw spacing is shown in Figure

3.5. To connect outputs, first remove the touch-proof cover plate covering the ter-

minal strip by removing the screw which holds it in place. To prevent the possibility of short-circuits, wrap or otherwise insulate exposed

loudspeaker cable and connectors. Also, a touch-proof cover plate, which covers the terminal strips, is provided to help prevent short circuits. The cover plate should be reinstalled after connecting outputs.

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 ft (7.6 m) 16 AWG

26-40 ft (7.9-12.2 m) 14 AWG 41-60 ft (12.5-18.3 m) 12 AWG Over 60 ft (18.3 m) 10 AWG

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

CAUTION: Never use shielded cable for output wiring.

3.7 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 cordset 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 3.10 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.

3.8 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.

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.

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 disconnect the power cord.

4. WARNING: 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, and may also void the product’s warranty.

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. Use caution when operating the amplifier with a 2-ohm load impedance on 1 channel. Do not operate the amplifier with less than a 2-ohm load impedance per channel when driving more than 1 channel. Due to the amplifier’s output protection, such a configuration may result in premature clipping, speaker damage or a blown power fuse.

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

4.1 Precautions

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

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.

5.1 Protection Systems

Your Crown amplifier provides extensive protection and diagnostic capabilities, including thermal level control, fault indicators, automatic high-pass filtering, DC protect, AC under-/over-voltage protection, inrush limiting, and variable-speed fans.

5.1.1 Thermal Level Control (TLC)

If an amplifier channel starts to overheat, the TLC circuit will engage that channel’s input compressor. By compressing the input, the amplifier will not generate as much heat and will have a chance to cool down. The degree of compression is proportional to the amount of overheating. If the channel becomes too hot for safe operation even after full TLC limiting, the channel will shut off, and the Thermal Indicator for that channel will flash brightly to alert the user that a state of thermal stress or overload has cause the channel to shut down.

5.1.2 Fault

If an amplifier channel requires service, the corresponding Fault indicator will illuminate to alert the user of this condition. If this occurs, return the amplifier to the Cro wn factory or to an authorized Crown service center.

5.1.3 Fault Isolation Topology (FIT)

Crown’s new FIT (Fault Isolation Topology) design isolates channel-specific faults, and prevents them from affecting remaining channels. If a CTs multi-channel amp is powering multiple zones, and a channel fails, the other zones continue to operate. FIT makes the CTs 4200 and CTs 8200 the most trustworthy multi-channel amplifiers in the business!

5.1.4 35-Hz High-Pass Filter

A fixed 35-Hz (70-Hz in CTs 4200) high-pass filter per channel pair is automatically inserted when the mode switch is set to either of the constant-voltage settings. The high-pass filter corner frequency can be set to 70 Hz, or bypassed, with a service option.

5.1.5 AC Under-/Over-Voltage Protection

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 5.1 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, consult your electrician.

5.1.6 Power Fuse

A fuse protects the amplifier from excessive AC current draw.

5.1.7 Inrush Limiting

A soft-start circuit in the power supply minimizes the amplifier’s current draw during power-on.

5.1.8 Variable-speed Fans

Continuously variable speed fans direct the airflow through the amplifier for cooling.

5.2.1 Switching Power Supply

Crown’s new 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 absorb the substantial waste that occurs when operating 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 120V/60Hz, 220V/50Hz, 230V/50Hz, 240V/50Hz, and 100V/50Hz AC mains.

5.2.2 Mode Switch

Each consecutive pair of channels has one four-position switch that selects the amplifier’s mode of operation. The switch positions are:

• Dual mode for 4 or 8 ohm operation.

• Dual mode for 70V constant-voltage operation.

• Bridge-Mono mode for 8 or 16 ohm operation.

• Bridge-Mono mode for 100V constant-voltage operation.

Be sure to turn off the amplifier before changing the Mode-switch setting.

5.2.3 Bridge Mode Indicator

This yellow LED indicates when the amplifier’s mode switch is set to the Bridge position. Each consecutive pair of channels has one Bridge LED.

5.2.4 Channel Level Control

The signal level for each input can be attenuated accurately by adjusting the 21-step Level Control (see Section 4.2). Figure 5.2 shows the amount of attenuation in dB for each detent.

Note: Attenuation per detent varies with operating mode since gain varies with operating mode. Attenuation amounts shown may vary ±6%.

Operation Manual

CONDITION: Power indicator is off.

POSSIBLE REASON

• The amplifier has lost AC power.

• 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 fuse has blown. Verify that input levels and output impedances are within safe ranges. Refer the unit to an authorized Crown service center for fuse replacement.

CONDITION: Power indicator is flashing.

POSSIBLE REASON:

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

Refer to section 5.1.6 for specific voltage requirements.

CONDITION: Fault indicator is on.

POSSIBLE REASON:

• The amplifier channel has stopped operating. Return the unit to an authorized Crown Service Center.

CONDITION: Distorted sound.

POSSIBLE REASON:

• Load is wired incorrectly or Dual/Bridge mode switch is set incorrectly. Check both.

• Input is overloaded by a signal level that is too high. Turn down your amplifier level controls, or turn down the input signal, until the clip light goes out.

• Thermal Level Control (TLC) is active.

Note: If the signal sounds distorted even though the Clip LED is off, the input signal is distorted. Check gain staging and output levels of the mixer or preamp.

6 Troubleshooting

Page 46

Operation Manual

CTs Power Amplifiers

page 46

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

without flashing and the amp is receiving an input signal. Signal indicator is flashing.

• Speakers not connected.

• Open circuit due to speaker failure.

CONDITION: No input signal.

(Signal indicator is not flashing even though audio is applied and channel is ready).

POSSIBLE REASON:

• Input signal level is very low.

• Input cables have become disconnected.

• There is a short on the amplifier output. First disconnect your speakers from the affected channel(s) one by one to determine if one of the loads is shorted.

6 Troubleshooting

CONDITION: Thermal indicator is flashing.

POSSIBLE REASON:

• The amplifier has become too hot for safe operation. Check for loads less than 2 ohms, and for excessive input levels. Check for proper ventilation and proper mode-switch setting. Driving lowimpedance loads while in high-voltage mode can cause overheating.

CONDITION: All channel thermal indicators are flashing.

POSSIBLE REASON:

• Power supply thermal overload.

• DC or excessive low-frequency signal at the amplifier’s output has enabled speaker protection.

CONDITION: Bridge LED is flashing.

POSSIBLE REASON:

• The mode switch was switched while the power was on.
