Setup

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
• HD-15 connector (if desired)
• 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.

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 Wiring DSi Amplifiers to DSi-8M Monitor Panel with HD-15 Connectors

2.5 Alternative: 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 two 3-pin Phoenix-style connectors (see Figure 2.5).
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. 2.6 Choose Output Wire and Connectors
Crown recommends using pre-built or professionally wired, high-quality, two- conductor, heavy gauge speaker wire and spade lug copnnectors or bare wire for your output connectors (Figure 2.6). To prevent the possibility of short- circuits, wrap or otherwise  insulate exposed loudspeaker cable connectors.
Using the guidelines below, select the appropriate size of wire based on the distance from amplifier to speaker.

CAUTION: Never use shielded cable for output wiring.

2.7 Wire Your System
2.7.1 Dual Mode
Typical input and output wiring is shown in Figure 2.7.
INPUTS: Connect input wiring for both channels.
Non-touch cover: Located over the amplifier out put terminals, this included accessory provides a shockproof cover for the output terminals. Remove the screw holding the cover onto the amplifier back panel, and remove the cover. Keep the screw.
OUTPUTS: Maintain proper polarity (+/–) on output connectors.
Connect Channel 1 loudspeaker’s positive (+) lead to Channel 1 positive (red) terminal of amp; repeat for negative (–). Repeat Channel 2 wiring as for Channel 1.
The non-touch cover has two tabs A and B (Figure 2.8). Insert tab A into the slot just to the left of the output terminals (Figure 2.9).
Put the screw through tab B, and screw it into the hole just to the right of the output terminals (Figure 2.9). 2.7.2 Bridge-Mono Mode
Typical input and output wiring is shown in Figure 2.10.
NOTE: Crown provides a reference of wiring pin assignments for commonly used connector types in the Crown Amplifier Application Guide available at www.crownaudio.com.
OUTPUTS: Cconnect the speaker across barrierstrip terminals 1+ and 2+.
IMPORTANT: Set the Bridge/Normal switch in the LCD screen to “Bridge.” See Section 4.1.5.
NOTE: In Bridge-Mono mode, only the Channel 1 Level control is functional (unless you make an alternate selection via the “Y” menu. See Section 4.1.5).

2.8 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. 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.

2.9 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 System Architect software to insert a highpass filter (see Section 4.1.6).
Alterna tively, switch in highpass filters at your mixer. Set the fil ter 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 frequency just below the lowest fundamental frequency of that channel’s instrument. 2.10 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.
   NOTE: In Bridge-Mono mode, only the Channel 1 Level control is functional (unless you make an alternate setting with the Y processing block).
   When Bridge Preset is used, both Level controls are functional.

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

Operation

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

1. Before use, your amplifier first must be config ured for proper operation, including input and out put 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 tech niques, 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. WARNING: Never connect the output to a power supply, battery or power main. Elec trical shock may result.
5. Tampering with the circuitry, 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.

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 Clip LED, even with no input connected and level controls set at minimum (Figure 4.1). If thisis 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 tempera tures (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 bedetermined and corrected as soon as possible. Without correction, the Thermal Protection circuit will typically reactivate.

4.1.4 Attenuator Security Covers
The included attenuator security covers (Figure 4.2) can replace the existing level-control knobs so that the ampli fier output level cannot be changed. The knobs snap into the front panel. 4.1.5 DSP Presets and Processes OVERVIEW
Figure 4.3 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 dis played on the screen.
The amplifier is shipped with factory-default JBL system presets. You can select the presets with the LCD screen and Menu navigation buttons. The ICONS in the dis play illuminate to show which DSP functions are currently in use for each preset.
Also, 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.harmanpro.com). Any custom settings can’t be saved by the front panel display, only by System Architect software.
From the front panel, you can change settings for several of the amplifier’s DSP processes: crossovers, EQ filters, delay, and output limiting. The ICONS in the display illumi nate 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 4.4 shows the Menu Tree, which is the navigation path of options in the Menu. Later in this manual is a table that shows how to access various presets and DSP processes.
The next pages describe each block in the menu tree.
Doing nothing returns you to the CURRENT PRESET after a time-out delay.
Starting from the CURRENT PRESET, Sel > Sel > Next goes to presets.
Sel > Next > Sel lets you configure the 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.
PRESETS: The DSi amplifier provides 20 presets total. One is “DSP OFF.” Fifteen are JBL loudspeaker presets that can be changed. Four are user presets that can be changed.
DSP PROCESSES
The DSi amplifier includes a number of DSP processes, which appear as ICONS on the screen. They are described below:
Y (Input Y): 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 out put. 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 high- frequency drivers to Ch. 1 when using this function.
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 software.
LIM (Limiter for Ch. 1 or Ch. 2): The amplifier can be set to hard-limit signals at one of these thresholds:

• –3 dB below clip
• –6 dB below clip
• –12 dB below clip.

BRg (Bridge-mono or Stereo): Use this option to set the amplifier to bridge- mono or stereo mode. When BRIDGE is active, the Ch. 1 input signal is used (unless you made an alternate setting with the Y processing block).
The tables on the next few pages describe what button sequence to press in order to achieve various functions.
Four identical tables are provided, each in a different language, for easy use in the field.

| CONDITION: No power to the amplifier.
• The amplifier’s Power switch is off.
| • The amplifier 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 amplifier 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.
