2.1 Unpack and Install 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 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). 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.

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.

Dimensions

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.

I-Tech Series specifications

The Crown Audio I-Tech Series represents a pinnacle of power amplification technology, designed to meet the demanding needs of live sound reinforcement and installation applications. Renowned for their flexibility, efficiency, and sound quality, these amplifiers integrate cutting-edge features that appeal to both professional audio engineers and musicians alike.

One of the key technologies employed in the I-Tech Series is the use of DriveCore technology. This innovative design allows the amplifiers to achieve high power output while minimizing size and weight. The DriveCore technology combines the efficiency of Class D amplification with superior sound quality, yielding a lightweight solution that maintains high fidelity and low distortion even at peak volumes.

The I-Tech Series amplifiers come equipped with a comprehensive suite of digital signal processing (DSP) capabilities. Each amplifier integrates sophisticated DSP algorithms that enable advanced speaker management, including extensive equalization, delay settings, and limiting controls. This ensures optimal performance for a variety of loudspeakers and installation scenarios, allowing users to tailor the output to the specific acoustical environment.

Connectivity is another strong point for the I-Tech Series. The amplifiers often include a variety of input options, providing flexibility for different setups, whether analog or digital. The inclusion of Ethercon connectivity enables seamless integration into a networked environment, allowing for remote control and monitoring via Crown's sophisticated software interface. Users can access real-time data about the system's performance, making adjustments on-the-fly to maintain optimal sound quality.

Durability and reliability are fundamental characteristics of the Crown I-Tech amplifiers. Built to withstand the rigors of touring and the demands of permanent installations, these amplifiers are housed in rugged enclosures that dissipate heat effectively while maintaining a compact form factor. Integrated protection circuits safeguard against over-temperature, over-current, and short-circuits, ensuring longevity even under extreme conditions.

In terms of power output, the I-Tech Series features a range of models, each capable of delivering substantial wattage to drive large sound systems with authority. The efficient cooling design allows for extended use without compromising performance, making them suitable for both large concerts and smaller venues.

In summary, the Crown Audio I-Tech Series amplifiers combine advanced technologies, including DriveCore and flexible DSP, to deliver powerful and high-quality audio performance. Their robust design, comprehensive connectivity options, and tailored control make them a premier choice for audio professionals seeking reliable and effective amplification solutions.
