The 4-channel I-Tech 4x3500HD incorporates Crown’s sixth-generation Class I engine with DriveCore™ technology to deliver 1,900 watts per channel into eight ohms, 2,000 watts per channel into four ohms and 4,000 watts into four ohms bridged with all channels driven at full bandwidth—all from an amp that measures just 2U rack spaces high. The 4.3-inch front-panel LCD touchscreen provides amplifier monitoring and access to key functions with color-keyed visuals that are similar to the at-a-glance FaderGlow™ indicators used on Soundcraft and Studer mixing consoles.

This power to size ratio is made possible by Crown’s exclusive DriveCore amplifier IC chip which combines the amplifier driver stage into 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.


A common concern among tour and installed sound professionals is a shortage of inputs and outputs on DSP-enabled power amplifiers. The I-Tech 4x3500HD provides a real-world solution with its four analog inputs, four AES3 digital inputs and four AES inputs over VDrive and the ability to select four CobraNet® inputs. SpeakON or banana plug speaker connectors are included, as well as a Neutrik® PowerCON AC input connector to prevent the power cord from coming loose in transit.

The amplifier is compatible with the HARMAN HiQnet System Architect and JBL HiQnet Performance Manager™ sound reinforcement system design software. The inclusion of JBL VerTec Version 5 DSP preset tunings for VerTec Series loudspeakers interface with the I-Tech 4x3500HD’s FIR filters to improve the loudspeakers’ sound quality and horizontal coverage performance. For enhanced control and monitoring capabilities the amplifier is also compatible with the Powered By Crown iPad/iPhone application.

The I-Tech 4x3500HD incorporates a host of additional useful features including Crown’s innovative LevelMax™ limiter technology that combines the operation of the amplifier’s Peak, Thermal and RMS limiters for more effective protection; a front-panel USB port that enables users to load preset amplifier settings or device files and update firmware.
