Setup

Unpack and Install Your Ampliﬁer

When 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):

1. Input wiring cables

2. Output wiring cables

3. Ethernet cables

4. 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 Instruc tions found at the beginning of this manual.

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 (counterclock wise).

Use a standard 19-inch (48.3 cm) equipment rack (EIA RS-310B).

You may also stack amps without using a cabinet.

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

Magnetic Field

CAUTION! Do not locate sensitive high-gain equipment such as preampliﬁers or tape decks directly above or below the unit. Because this ampliﬁer has a high power density, it has a strong magnetic ﬁeld which can induce hum into unshielded devices that are located nearby. The ﬁeld is strongest on the right side and right bottom of the ampliﬁer (facing the ampliﬁer).

If an equipment rack is used, we recommend locating sensitive equipment at least 20 cm (8 inches) away from the ampliﬁer.

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.

Connecting to AC Mains

WARNING: The third (ground) prong of the supplied AC power cord connector is a required 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 range and within the speciﬁed 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.

Packed with your I-Tech ampliﬁer is a clip that retains the power cord so it can’t pull out accidentally.

1. Locate the clip in a bag in the I-Tech packing carton.

2. Locate the IEC power connector on the back of the ampliﬁer. Above and below that connector are two slots. Stretch the ends of the clip and insert them into the slots.

Wire Inputs and Outputs

Wiring basics

• Always use shielded wire for input wiring. The higher the density of the shield (the

outer conductor) the better. Spiral wrapped shield is not recom mended.

• When using unbalanced lines keep the cables as short as possible.

Avoid lengths greater than 10 feet (3 meters).

• Do not run the audio input cables together with the high-level wiring such as loudspeaker wires or

AC cords. (This lessens the chance of hum and noise being induced into the input cables.)

• Turn the entire sound system off before changing any connections. Crown is not liable

for damage incurred when any transducer or compo nent is over driven.

THE CHANNEL 2 INPUT IS IGNORED by default in Bridge Mono mode. It can be summed using the input source selector and used instead of Channel 1.

Choose Input Wire and Connectors

Crown recommends using pre-built or professionally wired, bal anced line (two-conductor plus shield), 22-24 gauge cables and connectors. Use 3-pin male XLR connectors.

Unbalanced line may also be used but may result in noise over long cable runs.

The image below on the left shows connector pin assignments for balanced analog wiring or AES/EBU digital wiring. The use of standard analog cable with AES/EBU will result in diminished performance. For best results, 110 ohm shielded twisted-pair cable for AES/EBU signals is highly recommended. The image below on the right shows connector pin assignments for unbalanced analog wiring.

NOTE: Custom wiring should only be performed by qualiﬁed per sonnel.

Choose Output Wire and Connectors

Crown recommends using pre-built or professionally wired, high-quality, two- or four-conductor, heavy gauge speaker wire and connectors. Use Class 2 output wiring. You may use a 4-pole Speakon plugs, spade lugs, or bare wire for your output connectors. To prevent the possibility of short circuits, wrap or otherwise insulate exposed loudspeaker cable connectors.

CAUTION – SHOCK HAZARD: Potentially lethal voltages exist at the output connectors when the ampliﬁer is turned on and is passing a signal.

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

Distance Wire Size

up to 25 ft. 16 AWG 26-40 ft. 14 AWG 41-60 ft. 12 AWG 61-100 ft. 10 AWG 101-150 ft. 8 AWG 151-250 ft. 6 AWG

CAUTION: Never use shielded cable for output wiring.

Operation

Protecting Your Speakers

It’s wise to avoid clipping the ampliﬁer signal. Not only does clipping sound bad, it can damage high-frequency drivers. To prevent clipping, use System Architect software’s Level Max suite to enable or display the peak voltage limiter and average power limiter in your ampliﬁer’s built-in DSP. That way, no matter how strong a signal your mixer produces, the ampliﬁer output will not clip. Set the limiter threshold so that mixer signals above 0 dB or 0 VU on the mixer meters do not quite drive the ampliﬁer into clipping.

Also, avoid sending strong subsonic signals to the ampliﬁer. High-level, low-frequency signals from breath pops or dropped micro phones can blow out drivers. To prevent subsonic signals, use one of these methods:

• Insert a highpass ﬁlter between mixer output and ampliﬁer input (or between mixer and limiter).

• Use the I-Tech’s onboard DSP to set up a highpass ﬁlters.

• Switch in highpass ﬁlters at your mixer. Set the ﬁlter to as high a fre quency 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.

Startup Procedure

When ﬁrst turning on your ampliﬁer, follow the procedures in the Quick-Start Guide on page 4 (stereo) or page 5 (bridge-mono).

If you ever need to make any wiring or installation changes, don’t for get to disconnect the power cord.

For help with determining your system’s optimum gain structure (sig nal 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. 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. 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.

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 imped ance. Due to the ampliﬁer’s output protection,

such a conﬁgura tion may result in premature clipping and speaker damage.

9. CAUTION – SHOCK HAZARD: Potentially lethal voltages exist at the output connectors when the

ampliﬁer is turned on and is passing a signal.

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