2.1 Unpack Your Ampliﬁer

Please unpack and inspect your ampliﬁer for any damage that may have occurred during transit. If damage is found, notify the transpor tation company immediately. Only you can ini tiate 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 amplier (or a stable

sur face 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.

2.2 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 2.1 for ampli ﬁer dimensions.

You may also stack amps without using a cabinet.

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

2.3 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 back of the rack should be open.

Figure 2.3 Input Connector Phoenix Wiring, Bal anced (Top) and Unbalanced (Bottom)

2.4 Choose Input Wire and Connectors

Crown recommends using pre-built or professionally wired balanced line (two-conductor plus shield), 22-24 gauge cables and connectors. At the ampliﬁer inputs, use Phoe nix-style connectors (see Figure 2.3).

Unbalanced lines may be used, but may result in hum or RF noise over long cable runs.

NOTE: Custom wiring should only be performed by qualiﬁed personnel.

2.5 Choose Output Wire and Connectors

Crown recommends using pre-built or professionally wired, high-quality, two-conductor, heavy gauge speaker wire and connectors. You can use spade lugs or bare wire for your output connectors (Figure 2.4). To prevent the possibility of short-circuits, wrap or other wise insulate exposed loudspeaker cable connectors.

Using the guidelines below, select the appropriate size of wire based on the distance from ampliﬁer to speaker.

2 Setup (continued)

2.7 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 amplier; 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. You must operate your ampliﬁer from an AC mains power source with not more than a 10% variation above or a 15% variation below the ampliﬁer’s speciﬁed line voltage and within the specﬁed frequency require ments (indicated on the ampliﬁer’s back panel label). If you are unsure of the output voltage of your AC mains, please consult your electrician.

2.8 Protecting Your Speakers

It’s wise to avoid clipping the ampliﬁer signal. Not only does clipping sound bad, it can damage high-frequency drivers. The built-in clip limiter prevents clipping.

Also, avoid sending strong subsonic signals to the ampliﬁer. High-level, low-frequency signals from breath pops or dropped microphones can blow out drivers. To prevent subsonic signals, use the ampliﬁer’s DSP to insert a highpass ﬁlter (see Section

4.1.6). Alternatively, switch in highpass ﬁlters at your mixer. Set the ﬁlter to as high a frequency as possible that does not affect your program. For example, try 35 Hz for music and 75 Hz for speech. On each mixer input channel, set the ﬁlter fre quency just below the lowest fundamental frequency of that channel’s instrument.

2.9 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 indica tor 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. NOTE: In Bridge-Mono mode, only the Channel 1 Level control is functional (except for CH1 + CH2 Input Y mode).

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.

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.

3 Operation

3.1 Precautions

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

1. Before use, your ampliﬁer ﬁrst must be conﬁg ured 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, con sult 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. WARNING: Never connect the output to a power supply, battery or power main. Elec trical shock may result.

5. Tampering with the circuitr y, or making unautho rized circuit

changes may be hazardous and invali dates 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 sig nals 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 pre mature clipping and speaker damage.

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

9. Crown CDi ampliﬁers can directly drive 70V/high-Z loads. To conﬁgure your ampliﬁer for this mode of operation, see Section 4.1.6.

4 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.

4.1 Protection Systems

Your Crown ampliﬁer provides extensive protection and diagnostic capabilities, including output current limiting, microprocessor-controlled DC protection, and special thermal protection for the unit’s transformers and output devices.

4.1.1 Output Current Limiting

Output Current Limiting circuitry protects the ampliﬁer output stage from damage caused by short-circuit loads.

4.1.2 DC Protection

DC Protection shuts down the ampliﬁer in the event of an output DC offset exceeding 2V. In the majority of cases, DC protection is indicative of a faulty ampliﬁer channel, and will be accompanied by an illuminated red Clip LED, even with no input connected and level controls set at minimum (Figure 4.1). If this is the case, contact your dealer or service center.

4.1.3 Thermal Protection

The Thermal Protection circuit will activate if the internal heatsink temperature exceeds proper operating temperatures (176°F, 80°C). When the heatsink temperature has fallen to a safe level, this protection circuit will automati cally be reset. Principal causes of thermal protection are:

1) Inadequate ventilation of the equipment rack

2) Incorrect load impedance

3) Output cable short circuit

4) Blocked air vent

5) Heatsinks in need of cleaning

6) Cooling fan failure. The cause of your ampliﬁer’s thermal protection state should

be determined and corrected as soon as possible. Without correction, the Thermal Protection circuit will typically reactivate.

4.1.4 Non-Touch Cover

Located over the ampliﬁer output terminals, this included accessory provides a shock-proof cover for the output ter minals.

1. Remove the screw holding the cover onto the ampliﬁer back panel, and remove the cover. Keep the screw.

2. The cover has two tabs A and B (Figure 4.2). Insert tab A into the slot just to the left of the output terminals (Fig ure

4.3).

Figure 4.2 Interior of Non-Touch Cover

3. Put the screw through tab B, and screw it into the hole just to the right of the output terminals (Figure 4.3).

4.1.5 Attenuator Security Covers

The included attenuator security covers (Figure 4.4) can replace the existing level-control knobs so that the ampli ﬁer output level cannot be changed. The knobs snap into the front panel.

4.1.6 DSP Presets and Processes

OVERVIEW

Figure 4.5 shows the LCD screen and the three Menu navigation buttons: Sel/Enter, Prev/Up and Next/Down. These buttons let you step through the menu items displayed on the screen.

You can conﬁgure USER PRESETS with your own set tings. When you power off and back on, your settings will be as they were when you shut off the ampliﬁer. However, if you recall a user preset, all its DSP will be off– unless you had saved the preset using System Architect software (a free download from www.harman pro.com). Any custom settings can’t be saved by the front panel display, only by System Architect software.

The ICONS in the display illuminate to show which DSP functions are currently in use for each preset.

You can select the presets with the LCD screen and Menu navigation buttons.

From the front panel, you can change settings for several of the ampliﬁer’s DSP processes: cross overs, EQ bypass, delay, 70V mode, and output lim iting. The ICONS in the display illuminate to show which DSP functions are currently applied.

When you power-on the ampliﬁer for the ﬁrst time, the LCD screen displays DSP OFF (no DSP is applied). Subsequent power-ons display the preset that was active when you shut off the ampliﬁer.

Figure 4.6 shows the Menu Tree, which is the navi gation path of options in the Menu. Later in this manual is a table that shows how to access various presets and DSP processes

On the next page is a description of each block in the Menu Tree.

HOW TO ACCESS PRESETS AND DSP PROCESSES

NAVIGATING THE LCD SCREEN MENU: BASICS

To step through the Menu options, press the Sel, Next or Prev buttons as described in the table

later in this manual. ICONS illuminated at the top of the screen show

which DSP functions are active with the current preset.

When you are modifying a preset, its ICON ﬂashes. You can scroll through its settings with the Prev and Next buttons. When you see the desired setting, select it by pressing Sel.

Doing nothing returns you to the CURRENT PRESET after ten seconds.

In the LCD screen, if the PRESET icon is lit, the current pre set is unchanged from its stored settings. If the CUSTOM icon is lit, the current preset has been changed from its stored settings.

USER PRESETS: The CDi ampliﬁer provides 19 user presets which you can modify. For example, set up a user preset with a speciﬁc crossover frequency and a speciﬁc limiting threshold.

DSP PROCESSES

The CDi ampliﬁer includes a number of DSP processes, which appear as ICONS on the screen. They are described below:

Output Mode: The options are:

• 70V (70V/high-Z mode for Ch. 1 or Ch. 2)

• High Z – Channel is congured for 70V/high-Z

loads. (A 70Hz high-pass ﬁlter is automatically enabled whenever 70V is on.) It is a 24 dB/octave Linkwitz-Riley ﬁlter in the crossover section.

• Low Z – Channel is congured for low-Z loads.

Input Mode: The options are

• CH1+CH2 (Ch.1 input signal and Ch. 2 input

signal are summed and fed to both output channels.) This provides a 6 dB level boost.

• INPUT Y (Ch. 1 input signal goes to Ch. 1 and

Ch. 2 output. Ch. 2 input signal is ignored.)

• STEREO (Ch. 1 input goes to Ch. 1 output. Ch. 2

input goes to Ch. 2 output.) XOV (Crossover): The available crossover

frequencies are: OFF, 90 Hz, 100 Hz, 1200 Hz, 1500 Hz, 2000 Hz, 2-CH SUB, CUSTOM.

When you call up the XOV process, Ch.1 will always be set to low frequencies and Ch. 2 will always be set to high frequencies. DO NOT con nect highfrequency drivers to Ch. 1.

EQ (Equalization for Ch. 1 or Ch. 2): The

options are OUT or IN. When set to “IN”, equalization that you set up in System Architect software is applied to the signal. When set to “OUT”, equalization is bypassed.

DEL (Delay for Ch. 1 or Ch. 2): The delay times are OFF, 1-10 msec, 10-50 msec, and 0 sec. “0 sec” is a placeholder for any delay time set in System Architect soft ware.

BRG (Bridge-mono or Stereo): U se this option to set the ampliﬁer to bridge-mono or stereo mode. Wh en BRIDGE is ac tive, the Ch. 1 input sig nal is used (unless you ma de an alter nate setting with the Y processing block) .

5 Troubleshooting

CONDITION: Normal operation.

• This is normal operation for your amp.

CONDITION: Distorted sound.

• Input signal level is too high. Turn down your amplier

Level controls. NOTE: Your ampliﬁer should never be operated at a level which causes the Clip LEDS to illuminate constantly.

CONDITION: No power to the ampliﬁer.

• The amplier’s Power switch is off.

• The amplier’s power cord is unplugged.

CONDITION: No sound.

• The amplier is in “fault” mode. A Fault status can be

triggered when one of the ampliﬁer’s protection circuits is activated. First disconnect your speakers from the affected channels(s) one by one to determine if one of the loads is shorted. If the indicators return to normal status, then try a different speaker or cable to determine where the short is occurring. If no short can be found, turn off the amp and allow the amp to cool. If indicators do not return to normal after restarting your amp, check the fuse and replace if necessary, or return amp to Crown or an authorized Crown Service Center for servicing.

CONDITION: No sound.

• The amplier has just turned on and is still in

the 4-sec ond turn-on delay.

• Channel is in thermal protection.

• No input signal

• Input signal level is very low.

• Level controls are turned down.

• Speakers not connected.
