About Crown Audio I-Tech 4x3500HD

Take your audio experience to the next level with the I-Tech 4x3500HD DriveCore Series 4-Channel 4000W at 4Ohms Power Amplifier, the Binding Post Version. This high-powered tour sound amplifier is a pioneer in the industry, boasting four versatile inputs - Analog, AES3, and CobraNet - all of which are fully routable to any of the four outputs.

Each channel is equipped with a comprehensive set of OMNIDRIVEHD Processing features, including the highly-praised LevelMAX Limiter Suite and support for linear phase FIR filters, as utilized in the latest JBL V5 loudspeaker tunings. This, coupled with Crown's patented Class-I technology, ensures an uncompromising power output across all four channels, making the I-Tech 4x3500HD the flagship tour sound amplifier from Crown.

Experience unparalleled flexibility with a true Ethernet backbone that is fast, reliable, and scalable. The color LCD provides users with diagnostics and presets for effortless setup. The amplifier includes SLM (Sweep Load Monitoring) with system-level diagnostics and a front panel USB connector for transferring presets to and from a USB drive to the amp's DSP.

The new software interface, designed based on customer feedback, manages presets, facilitates easier system-level changes, and includes a configuration wizard. This amplifier stands alone in offering analog, AES, CobraNet, HiQnet, and Ethernet connectivity.

The I-Tech 4x3500HD refuses to compromise on quality. It features BSS OMNIDRIVEHD DSP processing with industry-leading IIR filters and linear phase FIR filters. High common-mode rejection eliminates hum and RFI on input cables, and professional-grade connectors are used for all inputs and outputs. The full power-supply voltage is always available, ensuring instantaneous power on demand. Quality-graded components allow you to drive the amplifier harder, while more total capacitance provides tremendous energy reserves for power bursts.

In comparison to other amplifiers, the I-Tech 4x3500HD stands out as the only tour sound amplifier that provides four routable inputs to any output (analog, AES, VDrive, or CobraNet). The LevelMAX peak voltage and RMS power limiters communicate with each other, resulting in smooth and accurate response and superior sound. The sixth-generation patented Class-I (BCA) circuitry couples power efficiently to the load and provides low AC current draw. The global power supply with universal AC input accepts 100-240VAC, 50/60 Hz (+/- 15%), making it a truly versatile and high-performing audio equipment choice.
