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 DPA series amplifiers are digital power amplifiers designed to meet the specialized needs of sound contractors for Multi-Zone distributed speaker systems. They are designed in six different models of Class D power amplifiers, divided in three different architectures to meet the requirements for all kinds of applications.
They combine the best of all features in one single series of amplifiers, providing an outstanding sound quality with all the known advantages of Class D Amplifiers. Such as the excellent efficiency and very low heat dissipation. And due to the complete passively cooled entity only a minimal of maintenance is needed, while ensuring maximum reliability.
The small size of a single rack space make them very interesting for fixed rack mount as well as mobile applications.
The DPA74 is built as multi channel power amplifier with four individual controllable channels containing various specific features and advanced protection circuitry which protects against DC malfunctioning, short circuit, overheating and overload.
The signal input connections are accommodated with balanced XLR connectors. The operation mode can be selected between Stereo mode, Bridge mode and Parallel mode. The output connections are accommodated with Euro-Terminal blocks.
