I-Tech Series Power Amplifiers

Bandpass Gain: In each channel of the I-Tech’s DSP, just before the output limiter and after the preceding filter, is a gain block (not shown on the Signal Path block diagram). Bandpass Gain adjusts the gain of this block.

Adjusting the bandpass gain in the LCD screen makes it easy to vary the level of subwoofers, midrange drivers and high-frequency driv- ers.

Rotate each channel’s Encoder knob to adjust the gain of that chan- nel’s bandpass filter.

Bandpass Gain

2.5 dB 0.0

4.2.4 MONITOR MENU

This menu lets you monitor the status of the amplifier. Starting from the Attenuation Screen, press Menu, then press Prev. Or, starting from the Advanced Menu screen, press Next to go to the Monitor Menu screen. Then press an Encoder knob to enter the menu.

Load Monitoring: Press an Encoder knob (or use IQwic) to turn speaker load monitoring off or on. When on, the load connected to the amplifier output is displayed. The text below the reported load indicates whether the value is within the limits set in IQwic or Sys- tem Architect. LOW means the load is below limits; HIGH means the load is above limits. NORMAL means the load is within limits.

Normal

Thermal %: This indicates the amplifier temperature in percent, where 100% is the maximum allowable temperature. If Thermal % reaches 100%, the amplifier is out of thermal headroom and has shut down (or will very soon).

Thermal %

0 0

AC Voltage: This shows the AC line voltage at the AC cord inlet to the amplifier.

Firmware Versions: Displays the firmware versions of the Dis- play and DSP. The two may not always match. Go to www.crownaudio.com to see what firmware is available.

Firmware Versions

Manufacturing Info: Displays the amplifier model, serial number, and date code.

Manufacturing Info

Crown IT6000

S/N:10143

Date:0054

Networking: Displays the amplifier’s IP address, subnet mask, HiQnet or IQ address, and MAC address.

Operating Time: This displays the number of hours the amplifier has been on since manufacture. Like a car’s odometer, it shows the total amount of operating hours and cannot be reset. All I-Techs come with a variable amount of operating time on them due to burn- in and testing before shipping.

Operating Time

466.5 Hrs

Note: To prolong the life of the memory devices, this value is stored only every 30 minutes. For this reason, operating time serves only as a general means of determining how long the amplifier has been “on.”

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.
