Inside and out, the I-Tech HD is one of the most technologically advanced professional touring amplifiers on the market today. Building on the decades of innovation, invention, and insight Crown is known for, the I-Tech HD features five new patents – three on the power supply alone – giving you an amp that goes well beyond the expected. At the heart of the new I-Tech HD is the BSS OMNIDRIVEHD™ processing engine. Four times faster than its predecessor and featuring Linear Phase FIR filters and LevelMAX™ limiters, OMNIDRIVEHD provides unmatched clarity and sonically pure signal processing.
Features
Innovation
- BSS OMNIDRIVEHD™ DSP processing with IIR filters and linear phase FIR filters
- Covered by five patents
- Fan has true tachometer feedback for fan fault protection and precise control over thermal performance, so the amp runs longer and harder than the competition
- Includes SLM (Sweep Load Monitoring) with system-level diagnostics
Performance
- Ultra smooth processing by onboard high-definition BSS OMNIDRIVEHD DSP with 24-bit, 192kHz Cirrus Logic SHARC A/D and D/A converters
- LevelMAX™ peak voltage and RMS power limiters communicate with each other, resulting in smooth and accurate response, better sound
- True Ethernet backbone – fast, reliable and scalable
- High common-mode rejection eliminates hum and RFI on input cables
- 6th-generation patented Class-I (BCA®) circuitry couples power efficiently to the load and provides low AC current draw
Versatility
- Global Power Supply; universal AC input accepts100-240VAC, 50/60Hz (±15%)
- Front-panel USB connector transfers presets to/from a USB drive to the amp’s DSP
- New software interface based on customer feedback manages presets, provides easier system-level changes, and includes a configuration wizard
- The only product available with analog, AES/EBU, CobraNet®, HiQnet™and Ethernet connectivity
- User -definable front panel security feature
- The only tour sound amplifier that provides inputs routable to any output (analog, AES, or CobraNet)
Power
- Professional-grade connectors for all inputs and outputs
- Full power-supply voltage is always available, allowing instantaneous power on demand
- Quality-graded components let you safely drive the amplifier harder
- More total capacitance provides tremendous energy reserves for power bursts
- 200Vrms peak output voltage provides clean transient peaks

A true turtleneck that retains a snug high neck.
Color: White, Size: X-Large
I've found this brand to have gotten better over the years as far as offering the American market what it needs in terms of realistic sizing. I only wish they'd realize that there are a lot of us who are long in the back and arms where my only choice is to go a size up and sacrifice a slim fit for sleeves that are long enough plus a back that doesn't go up past my waist just because I reach up for something, that and I like to be warm. So these are such nice quality turtlenecks that it's hard to complain about but maybe the company will read this. The snug neck stays up is plus number one since that's why I'm buying a full neck. They come with very nice weaves in the fabric, good enough for casual or formal wear. Finally the warmth you seek is there but I've worn them in what most would think isn't the right temp for a turtleneck. Also they have them in white! Yes, a lot of others just don't for reasons I can't fathom, and the pic you're seeing is accurate, these will form to your shape without being ridiculously thin material. Several washes later and they are as fine a garment as when I first wore them. I've only found one other brand that compares to these but it's much more expensive, COOFANDY is affordable in these times of expensive everything. Warm but also a lightweight shirt, I've gotten them really dirty with actual dirt and it washes out so well you'd never know it. Don't let my taking off one star stop you, try one yourself and you'll be coming back for more.
