3.5Back Panel Controls, Indica- tors and Connectors

A. Fans

Provide front-to-back forced airflow for cooling.

ANALOG INPUTS SECTION

B. Balanced Analog XLR Inputs

A 3-pin female XLR connector for each channel.

C. Balanced Analog XLR Loop-Through Outputs

Two 3-pin male XLR output connectors are pro- vided (one per channel). The signal at these connectors is paralled with the input signal for feeding the input signal to other amplifiers.

OUTPUTS SECTION

D. 4-Pole Speakon Output Connectors

Two high-current, 50A Neutrik® Speakon NL4MLP (mates with NL4FC and NL4), one per channel. Class 2 output wiring required.

These two connectors accept 2-pole or 4-pole Speakon connectors. See Figures 2.5 through

2.10and Tables 1, 2 and 3 for connector wiring. The top Speakon connector is wired for both channels so it can be used for bridge-mono wiring or for stereo wiring of two speakers to a single Speakon connector.

E. Binding Post Output Jacks

One pair per channel of high-current, 60A color-coded binding posts. Accepts banana plugs, wire or spade lugs.

F. Power Cord Connector

Standard 20 amp IEC inlet. Voltage range is indicated above IEC inlet.

G. Reset Switch/Circuit Breaker

If the current draw of the amplifier exceeds safe limits, this breaker automatically disconnects the power supply from the AC mains. The switch resets the circuit breaker.

DIGITAL INPUTS SECTION

H. AES/EBU Digital Input

This 3-pin female XLR connector accepts a dig- ital signal in the AES/EBU format.

I. AES/EBU Digital Loop-through Output Male XLR active/re-clocked AES/EBU digital loop-through. The signal at this connector duplicates the digital input signal for feeding the input signal to other amplifiers.

It is not recommended to loop through more than four amplifiers. If larger distribution of AES is needed, the use of an AES distribution ampli- fier is recommended.

NETWORKING SECTION

J. Preset Indicator

Yellow LED flashes to signal the number of the current preset if active.

K. Data Indicator

Yellow LED indicates HiQnet or IQ data activity. Data indicator flashes only when the amplifier is polled for data, or is polled to see whether it is online.

L. Network Connector

This Ethernet connector accepts an RJ-45 con- nector for networking. Built into the connector is a yellow LINK ACT indicator that shows net- work activity, and a green 100Mb indicator that shows a 100Mb network connection.

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.
