The I-Tech 4x3500HD amplifier is the industry's first high-powered tour sound amplifier featuring four inputs, Analog, AES3, and CobraNetTM, fully routable to any one of 4 outputs. Each channel features a complete compliment of OmniDriveHDTM Processing, including the acclaimed LevelMAXTM 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. | | DriveCoreTM | | A culmination of nearly two decades of R&D in PWM and switch-mode amplification, DriveCoreTM 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 | | True flexibility, each amplifier is capable of independently driving up to four separate zones with a full suite of processing options on each channel. | | Omnidrive HD | | With 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, it's easy to see how the decade-long partnership between Crown and BSS continues to go beyond "what's possible" and into "what's next.“ | | Global PSU | | Universal power supply with Power Factor Correction technology adjusts to any frequency or mains voltage between 100-240VAC in a controlled manner - and in real time - so you can use it anywhere in the world and it will always deliver full power. | | Efficiency/Power/Weight | | When compared to traditional, non-switching amplifiers, the I-Tech HD series weighs an average of 50 lbs. (22.68 kg) less. Additionally, the patented Universal Power Supply with Power Factor Correction combined with the patented Class-I PWM output stage of the I-Tech 4x3500HD provides greater than 90% efficiency at full power from 100-240VAC. | | Warranty | | Crown offers a five-year, no-fault, fully transferable warranty on every new I-Tech HD series amplifier we make - an unsurpassed industry standard. |

The new DEEP2 amp series features four class-H power amplifiers with toroidal core offering amplifying levels from 2 x 400 W till 2 x 810 W at 4 Ohm. During the development of this series we attached a great importance to the reliability and the durability of the amps in continuous operation, this is why we used exclusively high end and selected components for the construction of these products.
The DEEP2 series features a Clip Limiter as well as every common protection circuit. On the rear panel you will find all the common In- and Outputs.
The DEEP2 series will convince every user thanks to a dynamic and very clear sound which is perfectly adapted for Subbass applications as well as for multifunctional speakers. All models are lightweight and feature a robust steel plate housing and a very user friendly and compact design.
The DEEP2 series will prove to be a profitable and reliable choice for bands, renting companies and professional users thanks to its excellent price/performance ratio.
