Four channel tour sound amplifier with BSS OmniDrive HD processing

SRP from £10,166.67 + VAT

The I-Tech 4x3500HD amplifier is the industry's first high-powered tour sound amplifier featuring four inputs, Analog, AES3, and CobraNet™, fully routable to any one of 4 outputs. Each channel features a complete compliment of OmniDriveHD™ Processing, including the acclaimed LevelMAX™ Limiter Suite, and support for linear phase FIR filters as used in the latest JBL V5 loudspeaker tunings. Combine that with Crown's patented Class-I technology delivering uncompromising power output across all four channels, and it's easy to see why the I-Tech 4x3500HD is the new flagship tour sound amplifier from Crown.

  • True Power Density - Crown amplifiers run louder, longer, and with higher fidelity than competing amplifier designs. The I-Tech 4x3500HD is no exception, with four channels of patented Class-I technology packed into a compact 2U design.
  • DriveCore - A culmination of nearly two decades of R&D in PWM and switch-mode amplification, DriveCore™ is a Crown exclusive that combines hundreds of parts into one chip the size of a your fingertip, resulting in more efficiencies and unsurpassed reliability.
  • 4 In/4 Out - each amplifier is capable of independently driving up to four separate zones with a full suite of processing options on each channel.
  • OmniDrive HD - the latest programmable studio-grade 32-bit Sharc® processors with enhanced SIMD architecture and a proprietary D/A output filter for improved signal-to-noise at least 6 dB quieter than outboard DSP
