Product Description

Designed for the professional audio market, the Crown I-Tech 4X3500HD combines massive output power with intelligent signal processing in a single rack unit. The amplifier's onboard DSP delivers comprehensive loudspeaker management including crossover, EQ, limiting, and delay — eliminating the need for external processing equipment. With four independent channels each capable of 4000 watts into 4 ohms, the I-Tech 4X3500HD is ready to drive even the most power-hungry speaker systems. The Speakon output configuration provides the quick-connect, locking performance required for fast touring changeovers and eliminates accidental disconnects during high-energy performances.

Key Features

• 4-Channel Architecture: Four fully independent amplifier channels in a single 2U rack chassis for maximum density and flexibility.
• 4000W Per Channel @ 4Ω: Massive, clean output power for high-SPL applications including large-scale concerts, arenas, and permanent installations.
• Advanced Onboard DSP: Comprehensive digital signal processing includes parametric EQ, crossover filters, time alignment, limiting, and Crown's exclusive BandPass Limiter for speaker protection.
• HiQnet Networking: Full Harman HiQnet protocol support enables system-wide control, monitoring, and configuration from any HiQnet-compatible software platform.
• Speakon Outputs: NL4 Speakon locking connectors provide fast, safe, and reliable speaker connections ideal for touring applications.
• Crown's PFC Power Supply: Power Factor Corrected switching supply ensures consistent performance regardless of AC mains voltage variations globally.
• Comprehensive Protection: Clip limiting, thermal management, DC protection, RF interference filtering, and inrush current limiting safeguard the amplifier and connected loudspeakers.
• Lightweight Design: Advanced switching power supply technology reduces weight dramatically compared to traditional amplifiers at this power level.

Typical Applications

• House of Worship: Drive large main PA systems with precision DSP control for consistent, articulate congregational coverage. HiQnet integration allows remote monitoring by A/V staff.
• Touring: The Speakon outputs and I-Tech 4X3500HD's power-to-weight ratio make it the preferred choice for international touring production companies demanding fast setup and tear-down.
• Concert Venues: Permanent installations in mid-to-large concert venues benefit from the integrated DSP and network control, reducing front-of-house rack complexity.
• Stadiums & Arenas: High-SPL stadium systems require the massive headroom and multi-channel flexibility that the 4X3500HD provides.

Technical Specifications

Frequently Asked Questions

What is the difference between the Binding Post and Speakon versions of the I-Tech 4X3500HD?

Both versions are electrically identical and deliver the same 4000W per channel performance. The Speakon version (SKU: 4X3500HDS-U-USFX) uses NL4 Speakon locking connectors, which are preferred for touring applications requiring quick and secure plug-in connections. The Binding Post version uses traditional screw-terminal outputs, preferred for permanent installations.

Does the I-Tech 4X3500HD require external DSP processing?

No. The I-Tech 4X3500HD includes comprehensive onboard DSP that handles EQ, crossover, limiting, and delay functions. For most applications, no external DSP is required. However, it is fully compatible with external HiQnet system processors for larger integrated systems.

What software is used to configure the onboard DSP?

The I-Tech 4X3500HD is configured using Crown's System Architect software, which communicates over a standard Ethernet connection via the HiQnet protocol. Firmware updates are also delivered via this interface.

Can the four channels be bridged for even higher output?

Yes. Channels can be configured in bridged mono mode for applications requiring maximum single-channel output power. Consult the product manual for bridging configuration and impedance requirements to ensure safe operation.

What is the warranty on the Crown I-Tech 4X3500HD?

Crown professional amplifiers are backed by a 3-year limited warranty covering defects in materials and workmanship. Crown's extensive global service network ensures rapid turnaround for warranty and out-of-warranty repairs.
