Hardware Setup and Conguration

Wire Input Connectors

Crown recommends using pre-built or professionally wired balanced cables (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 odd-numbered channels (1,3,5,7) for each bridged pair need be wired.

AVB Connectors

For AVB audio connection, standard Category 6 cabling can be used.

When using the AVB Primary and Secondary input connections, pass the CAT 6 cable twice through a Ferrite core located as close to the ampliﬁer as possible. This is to ensure compliance with emissions regulations. See Figure 5.

Figure 3

Figure 4

Figure 5

Wire Output Connectors

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

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 6.

For best results, Crown recommends Panduit part #PV10-10LF-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.

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 6

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.

DriveCore Install Network Display Series Power Ampliﬁers

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.

DCi Network Display Series 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 input attenuators of the ampliﬁer.

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 8 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 clipping.

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.

Software Setup

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 Low-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 may be conﬁgured independently on multichannel models.

Set Up and Conﬁguration of the DriveCore™ Install Network ampliﬁers can be completed through HiQnet Audio Architect network via the Ethernet connection on the back of the ampliﬁer. Note: the AVB digital audio transport connectors cannot be used for control and monitoring of the ampliﬁer.

To quickly conﬁgure your DriveCore™ Install Network ampliﬁer, connect all of the ampliﬁers and conﬁguration computer to the same network. For more information on network conﬁguration, please visit www.archimedia.harman.com. In the following example, we will only show ampliﬁers.

When Audio Architect™ is ﬁrst loaded, the software will scan the network for HiQnet devices. All devices that are discovered on the network will be found under the ADD DEVICE tab on the left hand tree menu. If the devices are not found, then the network may not be conﬁgured correctly. See Figure 7.

. The ampliﬁer should be connected to a TCP\IP

• When the device is selected and highlighted in orange the ﬁeld is represented in red.

• The HiQnet address is not displayed, instead a dash is displayed as grayed out.

Devices not discoverable at the IP level

A device which is not discoverable at the IP level (invalid IP address etc) will not be able to report a HiQnet address. In this instance, the HiQnet ID ﬁeld will display a ‘?’ to indicate that the ﬁeld may exist but that the software does not have enough discoverability of the device to determine the value. A blank ﬁeld or ‘-‘ implies the value is null. The HiQnet ID ﬁeld may not be edited inline. Once edits have been made, it is critical to click the “Apply Current Edits” or “Apply and Exit” buttons.

Random ID

The device will be given a random HiQnet address. If you want to set the HiQnet address of a device to a random ID, check the Random ID check box. If the check box is unchecked before applying current edits, the prior HiQnet ID value will be restored.

All devices in the current ﬁlter view may be set to Random HiQnet ID by checking the check box in the column header. The individual check boxes for all devices will be checked if a single individual check boxes for all devices is subsequently unchecked the column header Random ID checkbox will be automatically unchecked.

If all devices in the current ﬁlter view are set to Random ID on and the Random HiQnet ID column header check box is checked, all devices may be set to Random ID off by unchecking the column header check box. The individual check boxes for all devices will be unchecked.

Devices not discoverable at the IP level

A device which is not discoverable at the IP level (invalid IP address etc) will not be able to report a HiQnet address. In this instance, the Random ID check box will be unavailable.

Status

Displays the current discovery status of the device. The Status ﬁeld may not be edited. Discovery status hierarchy is as follows:

• Discovered. If a device has a unique IP address and a unique HiQnet address, this condition will be shown unless the device is access controlled. When the

device is not selected, the ‘Discovered’ label is represented in green.

• IP conﬂict. If a device has an IP Address conﬂict, this error will be shown regardless of other status notiﬁcations. When the device is not selected, the ‘IP conﬂict’

label is represented in blue.

• HiQnet conﬂict. If a device has a unique IP address yet has a HiQnet address conﬂict, this error will be shown regardless of other status notiﬁcations. When the

device is not selected, the ‘HiQnet conﬂict’ label is represented in red.

• Locked. If a device has a unique IP address and a unique HiQnet address, this condition will be shown if the device is access controlled. When the device is not

selected, the ‘Locked’ label is represented in yellow.

• Discovering. This condition will be displayed if the device has had changes made to IP conﬁguration or HiQnet address and HiQnet NetSetter is waiting

to reestablish connection. When a device being rediscovered is not selected, all ﬁelds within the device row are displayed but is grayed out, represented in light gray.

Discovered - The ‘Discovered’ status is determined by the following conditions:

• The device is discoverable at the MAC Address level.

• The device has a valid and unique IP Address (manual or DHCP / Auto-IP).

• The device has a unique HiQnet address.

• The device is not Access Controlled.

IP conﬂict - The 'IP conﬂict’ status is determined by the following conditions:

• The device is discoverable at the MAC Address level.

• The device has an IP address which conﬂicts with another device which has already been discovered by NetSetter.

• The device is discoverable at the MAC Address level.

• The device has a valid and unique IP Address (manual or DHCP / Auto-IP).

• The device has a unique HiQnet address.

• The device is Access Controlled.

When the device has been discovered in the Locked state, an Admin password dialog prompt will be displayed. The Admin password must be entered before any ﬁeld can be edited.

• A successful login with the Admin password is required to enable ﬁelds for subsequential editing.

• This state may need to be reset on rediscovery after applying current edits, requiring the Admin password to be entered again.

Discovering - The ‘Discovering’ status is determined by the following conditions:

• The device had been previously discovered at least the MAC Address level.

• Edits had been made to one or more ﬁelds.

• The device is being rediscovered after applying current edits.

Since the sort order automatically updates when a ﬁeld within the sorted column is updated, the rediscovered device will occupy the same row on rediscovery. Unless DHCP / Auto-IP or Random ID has been set prior to applying current edits, in which case the rediscovered device will occupy the appropriate row in the current column sort order.

Match Devices allows users to associate ampliﬁers within their venue design to ampliﬁers on the network. In the Match Devices tab, the following options are available:

Figure 11

• Refresh Networking: Clicking this button will temporarily take Audio Architect ofﬂine, then restart the network.

• Match

- Auto-Venue: Automatically enables matching between all the devices in the Audio Architect venue.

- Detach: Removes the device's virtual connection from Audio Architect.

• Editing

- Undo: Erases the last change done, reverting to the previous state.

- Redo: Re-establishes the previous state.

• Show – The checked items are displayed along side the appropriate devices in the venue; Device Names, Rack/Array Names, HiQnet Addresses, and IP

Addresses. In Synchronize Venue, each device will be shown with either a Receive icon or a Send icon.

• Receive – Device settings will be downloaded to the Audio Architect.

• Send – Device setting will be sent from Audio Architect to the device.

When going Online, the following options are possible:

1. If one or more devices in the Venue are not matched AND corresponding devices are available on the network, going online lands in Match Devices mode.

2. If all the devices in the Venue are matched, going online lands in Synchronize Venue mode. In Synchronize Venue mode, the user is given the option to either

Send data from Audio Architect to the device or Receive data from the device to Audio Architect.

3. If no devices require to be synced, going online lands in Run Venue mode.

General Purpose In/Out Control Port

DriveCore Install Network ampliﬁers come with a 2-in, 2-out General Purpose In/Out (GPIO) control port in the form of a 6 position RJ-11 connector. The Control Port has multiple functions and uses which include preset selection, and gain control among others.

Hardware Speciﬁcation

Inputs are analog capable of either binary or analog control of a State Variable (SV) within the ampliﬁer. Outputs are binary only that represent an SV of the ampliﬁer. Additionally, outputs can be controlled independently (on/off, polarity) via the software.

PIN 1: Output 1. 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V. PIN 2: Output 2. 0VDC to +3.3VDC output. Output impedance = 1KΩ pullup to +3.3V. PIN 3: Input 1. 0VDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance > 20KΩ. PIN 4: +3.3VDC output. ILIMIT = 30mA. Output impedance = 100Ω to +3.3V. PIN 5: Input 2. 0VDC to +3.3VDC input. Logic = TTL thresholds. Analog = full scale 0-3.3V. Input impedance > 20KΩ. PIN 6: GND.

Conﬁguration of the Control Port Inputs

2 inputs: Can be variable (connect to pot) binary (connect to switch) or multilevel connect to rotary switch and voltage steps.

• Audio Architect is used to assign up to 40 SV's to each input.

• An input mode is selected.

SET - Sets the assigned SV(s)to a speciﬁc value.

VARY - Continuously varies the assigned SV(s) by a speciﬁed value, typically a volume pot application.

PRESET - Recalls the max preset in one state (high) and the min preset in the other state (low).

BUMP - Similiar to vary but implemented with a button instead of a pot. A high level will bump the assigned SV(s) by a speciﬁc value.

AUTOBUMP - Similiar to bump, but will continue to bump the assigned SV(s) value as long as the input state is changed.

Right click on a DCIN in the venue. Select “Conﬁgure Control Ports”. A new tab labeled “(ampliﬁer name) – Control Ports” will open.

Software Parameters

High Limit – Available only on input, and only for parameters in “Analog Input” mode. This ﬁeld determines the value that the selected assigned parameter will assume

when the control port input is at the maximum end of its range.

Input – Selects between control port inputs, labeled 1 and 2.

Low Limit – Available only on input, and only for parameters in “Analog Input” mode. This ﬁeld determines the value that the selected assigned parameter will assume

when the control port input is at the minimum end of its range.

Mode – For the control port input, the Mode ﬁeld determines how the assigned parameters will be controlled. For the control port output, the Mode ﬁeld determines the

conditions under which the output status will change.

Off Value – Available only on input, and only for parameters in “Direct Action” mode. Determines what the value of the selected assigned parameter will be when the

control port input is logic “Low”.

On Value – Available only on input, and only for parameters in “Direct Action” mode. Determines what the value of the selected assigned parameter will be when the control

port input is logic “High".

Output – Selects between control port outputs, labeled 1 and 2.

Output Polarity – Enables selection between “Normal” and “Inverted".

Parameter Assignment – List of parameters that are currently assigned to a given control port input.

Once an SV has been added, its type will determine which MODE options become available. If a binary SV has been assigned, only the “Direct Action” mode is selectable, and the “ON VALUE” and “OFF VALUE” parameters can be toggled as desired. However, if a non-binary SV is added, the “Analog Input” Mode becomes available. In this mode, the ON and OFF VALUE ﬁelds are unused, and the “HIGH LIMIT” and “LOW LIMIT” ﬁelds appear and become accessible. The LIMIT ﬁelds allow control of an SV over a speciﬁed range.

Conﬁguration of the Control Port Outputs

2 outputs: Binary only.

• There is a polarity control on each output so that it may function as active-high or active-low.

• Output Mode 1 - Manual: Controlled directly by the output enable button.

• Output Mode 2 - Report Errors: Active when any enabled error is reported. The indicator will stay on for up to 60 seconds after the error is cleared. Errors include:

Load Supervision

AC Line Voltage is out of range

Hardware Protection(faults)

Over temperature (any channel or power supply)

Amp output clipping

Processing output clipping (off by default)

Analog Input clipping (off by default)

• Output Mode 3 - Report online status: Active when HiQnet connection is lost. The length of time to wait for a time out is user adjustable, default=60sec.

The Control Port output conﬁguration options can be found directly below those for the input. No parameters can be assigned to the outputs. Instead, there are three modes available: Manual, Report Errors, and Report Online Status. Manual mode enables direct control over the selected output. In “Report Errors” mode, the output status will change if any errors are reported to the network, such as clip errors, temperature errors, line voltage errors, etc. Finally, in “Report Online Status” mode, the output status will change if no network communication is detected for at least 60 seconds. The control port output does not turn off right away when reporting errors or online status. There are several reasons for this. The online status does not change quickly, it can take up to 60sec to drop ofﬂine or to recover. In these modes, the output is intended to be used with devices such as a backup amp switcher or an electro-mechanical system. We want to prevent this output from toggling on/off quickly. It may take the output up to 90 seconds to recover (i.e. switch states) from an error or loss of connection.

Aux Port/Sleep/Amp Status

AUX Port

The AUX port can be used for basic monitoring of the ampliﬁer and for remote standby. The port is a 3 pin block connector with pin-2 used as ground.

Sleep

The ampliﬁer can be put to sleep by connecting pins 1 and 2 on the AUX port. When applying this connection, the ampliﬁer will shut down and remain in sleep until the connection between pins 1 and 2 is open. While the ampliﬁer is in sleep, the front panel power button is disabled. When the connection between pins 1 and 2 is open, the ampliﬁer will revert to its last conﬁguration and begin to output audio within 20 seconds. Communication via the network will take as long as the network interface card boots. If the front power button is pressed while the amp is in sleep mode, the blue power indicator will blink twice.

Amp Status

AMP STATUS can be used for basic monitoring of the ampliﬁer. Monitoring of the ampliﬁer can determine if the ampliﬁer is operating within optimal parameters or if the ampliﬁer has been shut off or is in fault. Between pins 2 and 3, there will be either a +5VDC potential or a 2Hz square wave (heart beat). This option can be found in the AMP INFO button on the main ampliﬁer page.

Introduction

Your DCi Network Display Series ampliﬁer has a wide variety of onboard Digital Signal Processing (DSP). HiQnet Audio Architect software lets you adjust the DSP settings, such as ﬁlter slope, compression ratio, EQ frequency bands, and so on.

A preset is a group of DSP settings that conﬁgure the amp for a speciﬁc application. For example, you might use one preset that optimizes the amp’s DSP for a JBL tri-ampliﬁed speaker setting. You might use another preset that sets up the DSP for a stereo pair of loudspeakers of your choice. You can

choose any of 20 presets.

Ampliﬁer Presets and Speaker Tunings

Preset 1 is the factory default preset and cannot be overwritten. It sets up the ampliﬁer for pass-thru operation with no DSP features enabled. The DCi Network Display Series ampliﬁer works with two types of presets:

User Presets – Using Audio Architect, you can create your own custom DSP presets, label them and send them to the DCi Network Display Series ampliﬁer. The

amp stores those presets in ﬁrmware.

Downloadable Presets – Available for download from a variety of manufacturers, these presets are conﬁgured for optimal performance and can be sent to the

ampliﬁer via Audio Architect.

User Presets

User presets are DSP presets that are conﬁgured manually. The following three steps outlines setting up User Presets:

1. Adjust the DSP settings as desired in the Audio Architect software.

2. Save this group of settings as preset, you will be prompted to name it.

3. Download the preset to the DCi Network Display Series ampliﬁer. See the software Help ﬁle for details. As soon as you save the setting as a preset, it is sent to

the ampliﬁer.

Speaker Tunings

Crown and JBL engineers have designed DriveCore Install DSP settings that are optimized for various JBL loudspeakers. Speaker tunings can be downloaded at the following website: www.jblpro.com. An improved speaker tuning approach has been developed for the DriveCore Install Network Series. The system is software library based rather than device preset based. The new approach offers signiﬁcant beneﬁts:

• Unlimited number of tunings organized into an unlimited number of libraries.

• Simple and fast drop-down tuning recall/store/delete within device GUI.

• Channel/band speciﬁc tunings – no more managing tunings across channels or amp chassis. Also yields logical one-to-one correlation of amp output

to transducer/band.

• Faster tuning load/store times – much easier to compare and run A/B tests on multiple tunings without audio dropouts.

• Library based – allows logical groupings and archiving of similar tunings (e.g. Screen Array Series or VTX Series, etc.).

• Tunings can be held within but are de-coupled from device presets. Eliminates concern of accidentally deleting or changing other device parameters –

speaker tunings only contain the parameters required for speaker tunings! Now presets can be used for complete device conﬁgurations – as intended.

• Simpler and faster third-party and user tunings and libraries development – more people will be willing to develop custom or 3rd party tunings.

• Single panel access to all required tuning parameters – easier/faster to create/modify tunings.

Speaker Tuning Panel

A new “speaker tuning” icon is implemented on the main device panel for each channel of DCi ampliﬁers. Double-clicking the speaker tuning icon will open the basic Speaker Tuning Panel (STP). See Figure 32.

Figure 32 Basic Speaker Tuning Panel.

Basic STP functions are:

Recall

Loads the selected tuning from the working library (drop-down list) into the respective channel.

Store

Stores the STP settings from the respective channel into the working library with speciﬁed user name. The stored tuning is then available in the drop-down list for any other channel or amp.

Delete Deletes the selected tuning from the working library.

Speaker Manufacturer

Software-Controllable Onboard DSP

Crown DriveCore Install Network ampliﬁer have Digital Signal Processing built into the ampliﬁer. When you use an DriveCore Install Network amp, the loud speaker processors, crossovers, limiters and delays are in the onboard DSP – so discrete rack mount devices are

not needed. This drastically cuts setup time, commissioning, rack space and costs. The DriveCore Install Network DSP can be monitored and controlled with a computer running Audio Architect software, and connected to the ampliﬁer Network Connector by a Category 5 Network cable.

Some applications for this DSP are:

• Conﬁgure signal ﬂow

• Optimize system gain structure

• Conﬁgure speaker conﬁgurations (set the drive levels, frequency bands, delays and limiting for your particular speakers)

• Conﬁgure EQ, ﬁltering, and much more.

See the Audio Architect Help ﬁles for more detailed information.

Figure 34 Main DCi Interface

On the left of this screen is the Input and Output Signal Level Monitor (explained later on this page). On the right side are rows of DSP selection buttons for each channel. When you double click on a button, a control panel opens for that button’s function.

Also on the right are buttons that open control panels for these functions:

• Ampliﬁer mode

• Signal generator (pink noise and sine wave)

• Ampliﬁer information

• Recall and store presets

• Preset manager

• Apply to others (apply this ampliﬁer’s DSP settings to other devices)

We’ll explain each of these functions on the next several pages.

LevelMax™ Suite

This is a suite consisting of a peak voltage limiter, RMS power limiter, clip limiter and transducer thermal limiter. First you will set the mode to automatic or advanced: See Figure 39.

• Automatic mode: The software determines the best settings based on the signal characteristics. You can modify only the RMS threshold, Speaker Thermal

threshold and time constant. Everything else is set automatically.

• Advanced mode: You can modify the RMS threshold, Speaker Thermal threshold, time constant, Peak threshold and Peak/RMS release. Peak Voltage Limiter This

limits the peak voltage output of the ampliﬁer.

• On: Enables or disables this function. You’ll set the parameters below:

• Threshold: Sets the level, in absolute voltage, which the limiter will allow from the ampliﬁer. The range is from 1 Vpk to 255 Vpk.

• Attack Time: Sets the attack time of the limiter. The attack time is deﬁned as the time it takes the limiter to attenuate the output signal by 20 dB. The range is from

.1 millisecond to 100 milliseconds. The Instant setting attack time is instant (0 millisecond).

• Release Time: Sets the release time of the compressor. The release time is deﬁned as the time it takes the limiter to increase the output signal by 20 dB. The range

is the same range as attack time above.

Figure 39 LevelMAX™ Main Page

Transducer Thermal Limiter

This limits the long-term output power of the ampliﬁer to what the loudspeaker load can handle without overheating and going into thermal compression. You can set the voltage level at which the thermal limiter engages, the thermal response time and thermal voltage. Your loudspeaker manufacturer might be able to provide this information.

Meters show the ampliﬁer output level in dBFS; and peak, RMS, and total gain reduction.

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. In addition, be sure that the load connected to the ampliﬁer is within 2 - 16 Ohm limit (4 - 16 Ohm Bridge Mono). If wiring is veriﬁed as correct and the fault condition persists, see Page 45 for servicing information.

Auto Insertion High-Pass Filters

A 35 Hz high-pass ﬁlter is inserted automatically when a channel is selected for operation.

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.

Power Breaker

The ampliﬁer utilizes a breaker to protect from excessive AC current draw.

Fan-cooled Chassis

DCi Series ampliﬁers are cooled by quiet, variable speed fans. Maximum fan noise level of a DCi ampliﬁer is 47 dBa @ 1M. The fans will pull air from the front to the rear of the ampliﬁer.

The following fault conditions cause the fan to turn on full speed:

• High Frequency fault

• DC fault

• Short circuit fault

• Thermal fault

• Rail fault

After a fault, the fan will remain at full speed for at least 60sec.

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.
