About Crown Audio I-Tech 4x3500HD

After extensive research and development, the I-Tech 4x3500HD DriveCore Series 4-Channel 4000W at 4Ohms Power Amplifier with speakON Output has emerged as the industry's premier high-powered tour sound amplifier. This innovative device boasts four versatile inputs - Analog, AES3, and CobraNet - all of which are fully routable to any one of its four outputs.

Each channel of the I-Tech 4x3500HD is equipped with a comprehensive suite of OMNIDRIVEHD Processing, including the highly-regarded LevelMAX Limiter Suite and support for linear phase FIR filters. These features are integral to the latest JBL V5 loudspeaker tunings.

The amplifier's patented Class-I technology ensures uncompromised power output across all four channels, making the I-Tech 4x3500HD a standout in Crown's flagship tour sound amplifier line.

This device offers unparalleled flexibility, featuring a true Ethernet backbone for fast, reliable, and scalable connectivity. Its color LCD provides users with diagnostics and presets for effortless setup, while the inclusion of Sweep Load Monitoring (SLM) offers system-level diagnostics.

The front panel USB connector allows for easy transfer of presets to and from a USB drive to the amplifier's DSP. The device's software interface, designed based on customer feedback, manages presets, facilitates system-level changes, and includes a configuration wizard.

The I-Tech 4x3500HD is the only product in its category that offers analog, AES, CobraNet, HiQnet, and Ethernet connectivity. It also features BSS OMNIDRIVEHD DSP processing with industry-leading IIR filters and linear phase FIR filters.

The amplifier's high common-mode rejection eliminates hum and RFI on input cables, and its professional-grade connectors ensure reliable connections for all inputs and outputs. The full power-supply voltage is always available, providing instantaneous power on demand.

Quality-graded components allow you to drive the amplifier harder, and its total capacitance provides substantial energy reserves for power bursts. The I-Tech 4x3500HD is the only tour sound amplifier that provides four routable inputs to any output (analog, AES, VDrive, or CobraNet).

Its LevelMAX peak voltage and RMS power limiters communicate with each other, resulting in smooth and accurate response and superior sound. The amplifier's sixth-generation patented Class-I (BCA) circuitry couples power efficiently to the load and provides low AC current draw.

Finally, the I-Tech 4x3500HD features a Global Power Supply with a universal AC input that accepts 100-240VAC, 50/60 Hz (+/- 15%), making it a truly versatile and reliable choice for professionals in the audio industry.
