What is it?A 2U, 4-channel power amplifier – the latest model in Crown’s flagship I-Tech HD Series.DetailsThe I-Tech 4x3500HD delivers 1.9kW per channel into eight ohms, 2kW per channel into four ohms and 4kW into four ohms in bridged mode with all channels driven at full bandwidth. The high power-to-size ratio is made possible through Crown’s proprietary DriveCore amplifier IC chip which combines the amplifier’s driver and power output stages to significantly reduce overall size and power consumption requirements. The design includes a range of advanced features including a 4.3” TFT capacitive touchscreen, Harman’s HiQnet System Architect 2.0 control functionality and Version 5 DSP preset support for JBL’s newly-launched VTX Series V25 plus Vertec Series line array speakers.The LCD touchscreen provides amplifier monitoring and access to key functions with colour-keyed visuals similar to the FaderGlow indicators used on Soundcraft and Studer mixing consoles. DriveCore technology also gives the I-Tech 4x3500HD better control features and ability to recover more quickly from high-voltage transients, improving reproduction and offering improved low-frequency response.With its proprietary BSS OmniDriveHD processing engine, the design offers enhanced DSP sound-tailoring features and employs 32bit/192kHz A/D and D/A converters for improved sonic clarity. Crown’s exclusive linear phase FIR and IIR filters provide optimised speaker crossover points with improved mid-range clarity and off-axis response.And another thing…The I-Tech 4x3500HD includes four analogue, four AES3 digital and four AES inputs over VDrive and also has the ability to select four CobraNet inputs. For enhanced control and monitoring capabilities the amplifier is also compatible with the iPad/iPhone Powered By Crown application.
