About the Crown Audio I-T4x3500HD

The Crown Audio I-T4x3500HD Pro Power Amplifier delivers 1900 watts per channel into 8 ohms, 2000 watts per channel into 4 ohms and a massive 4000 watts into 4 ohms bridged with all channels driven at full bandwidth, all from an amplifier that's just two rack spaces high. This power-to-size ratio is made possible by Crown's exclusive DriveCore amplifier integrated circuit chip. The DriveCore IC combines the amplifier driver stage and the power output stage (along with additional audio-signal functions) to dramatically reduce overall size and power-consumption requirements and yield energy-efficient operation that conforms to Harman International's GreenEdge environmental initiative.

DriveCore technology also gives the I-Tech 4x3500HD the ability to better control and more quickly recover from high voltage transients, for a highly accurate reproduction of the input signal and better low-frequency response. The I-Tech 4x3500HD provides an ideal real-world solution with its four analog inputs, four direct AES3 digital inputs plus four AES inputs over VDrive, or alternatively the ability to route four CobraNet inputs over VDrive. I-Tech HD is the only series of amps providing both AES and CobraNet connectivity as standard.

The amplifier is provided with a choice of either Speak ON or banana-plug/binding- post output speaker connectors and both employ a Neutrik Power Con 32 Amp AC input chassis connector to prevent the power cord from coming loose in transit. The Speak ON version of the amplifier provides two NL-4 connectors, with one supplying the first pair of channels, the other supplying the second pair of channels and below them, an NL-8 distributing all four channels of the amplifier.

The Crown I-Tech 4x3500HD provides more DSP sound-tailoring capability than any other amplifier on the market. Its proprietary BSS Omni Drive HD processing engine employs 32 bit/192 kHz A/D and D/A converters for superb sonic clarity and the ability to precisely tailor the amplifier's audio output. Crown's exclusive linear phase FIR and IIR filters provide optimized loudspeaker crossover points with improved midrange clarity and off-axis loudspeaker response. The 4x3500HD amplifier is compatible with JBL's HiQnet Performance Manager sound reinforcement system design software, a workflow-oriented application that facilitates the design and operation of touring and live performance sound systems.

The I-Tech 4x3500HD is well suited to powering pairs of VT4889 and VT4888 enclosures with a single amp, using two channels for the lows, another for mids and the fourth for highs. It will be featured in the upcoming Crown Audio VRack4, creating an amplifier rack that is complementary to the current VRack2 that is loaded with three stereo I-Tech HD 12000 amps.
